Appointment letter format: the employment contract in letter form
Issued after the offer is accepted and before the first day, the appointment letter is the document both sides reach for when something is disputed. Here is what each clause does, who signs, and what the signed duplicate is for.

What an appointment letter is, and who it is really for
An appointment letter is the employment contract written as a letter. The offer letter that came before it asked a candidate to say yes; the appointment letter records what they said yes to, in enough detail that neither side has to rely on memory later. It is issued by the employer, on letterhead, after the offer has been accepted and usually on or shortly before the joining day, and it is signed by somebody who has the authority to bind the company. The employee signs a duplicate and returns it, and from that moment the letter is the terms.
This page is written for the people who actually draft these letters: an HR executive at a mid-sized company, a founder hiring their fifth employee, the manager of a school or clinic or shop who has never had a template that was not copied from somewhere else. It explains the letter rendered below clause by clause — why each clause is there, what it is protecting, and what changes when the appointment is part-time, fixed-term or academic. The FAQ at the end answers the questions an employee asks when the letter lands on their side of the desk.
The letter has to do two things at once. It has to be readable by the person receiving it, who is about to change their life on the strength of it and should not need a lawyer to follow it. And it has to be precise enough that if the relationship goes wrong — a disputed notice period, an unpaid variable, a transfer nobody mentioned — the letter answers the question rather than starting an argument. Most of the decisions on this page are about holding those two demands together on a page and a half of A4.

The letter, block by block
Top to bottom, the way it is read. Each block carries a decision the drafter has to make, and the letter above shows one defensible answer to each of them.
- 01
The letterhead
The company’s name, department, address, phone and email, printed at the top. It is what makes the document a letter from the company rather than a note from a person.
An appointment letter is issued on the employer’s letterhead, and in the letter above the letterhead names the department as well as the company: Human Resources, Trilok Systems, with the Gurugram address, a landline and an HR mailbox. The department line matters more than it looks. It tells the employee where to send the signed duplicate and whom to write to about anything in the letter, and it means the reply does not land in one individual’s inbox and leave with them when they resign.
A small employer with no printed stationery does not need to buy any. A typed header with the registered name exactly as it appears on the company’s registration, the address of the establishment, and a phone number and email that will still be answered in two years is a letterhead. What to avoid is a trading name that differs from the legal name, because the entity that appoints is the entity that pays salary, deducts tax and issues the experience letter later, and all of those documents should read the same.
- 02
The date
The date the letter is issued. It is not the joining date, and the two should not be confused.
The letter above is dated 21 September 2026: two weeks after the offer of 7 September was accepted, and two weeks before the 5 October joining date. That gap is typical and it is useful. It gives the employee time to read and return the duplicate before their first day, and it means the terms are settled before anyone is on the payroll. Some companies issue the appointment letter on the joining day itself, which works but leaves no room for a question to be asked and answered before the person has already started.
Whatever the date is, it should be the real one. An appointment letter back-dated to the joining date because HR was late is a small dishonesty that becomes a real problem the day somebody has to prove when the terms were communicated. If the letter is late, date it the day it is signed and let the effective date inside the letter do the work of saying when employment began.
- 03
The employee’s address
The person being appointed, with their postal address, as on any formal letter. Name and title, then the address on separate lines.
The letter above is addressed to Mr. Aarav Nair at his home address in Kochi, which should be the same address the offer letter used and the one he gave in his application. The address block is not decoration. It may be the address the company uses for any formal notice later, and using the same one throughout the file avoids the argument about whether a letter reached the person it was meant for. If the employee moves, the change goes on the file in writing.
Do not put an employee ID, designation or department in the address block of an appointment letter. The person does not have any of those yet; the appointment sentence in the body is where they are conferred. Compare a relieving letter, where the address block does carry the designation and ID, because by then they are facts about the person rather than things the letter is granting.
- 04
The subject line
One line that names the document and the post. It is the line a reader uses to find this letter in a file of twenty.
The subject above says what the document is and which post it concerns, and nothing else. It does not repeat the company name, which is on the letterhead, or the employee’s name, which is in the address block, or the grade and team, which belong in the body where they can be read in context. A subject line that runs to two lines has taken on work the body should be doing.
Use the same noun for the post that the rest of the company uses. If the offer said “Data Analyst”, the appointment letter says “Data Analyst” — not “Analyst — Data” or “Data Analyst I”. Titles that drift between the offer, the appointment letter and the payroll system are one of the most common reasons an experience letter has to be reissued years later, and the subject line is where the drift usually starts.
- 05
The reference to the offer and the appointment sentence
The first paragraph of the body. It ties this letter to the accepted offer, then makes the appointment in one sentence: post, grade, team, effective date.
The letter above opens by referring to Aarav’s acceptance of the offer dated 7 September 2026, and then appoints him as Data Analyst (Grade L2) in the Platform Analytics team with effect from 5 October 2026. The reference does two jobs. It makes the chain of documents explicit, so anyone reading the file later can see that an offer was made and accepted before the appointment was issued. And it establishes that this letter follows and supersedes the offer where the two differ, which is the ordinary rule and one worth stating in so many words if the company’s practice is to say it.
The appointment sentence should carry everything about the role that a payroll clerk or a future HR person would need, and nothing they would not: the designation, the grade or level if the company uses one, the team or department, and the effective date. The reporting manager’s name is commonly left out, because managers change and the letter should not need reissuing when they do. The sentence that follows — that the terms and conditions are set out below — is the hinge that hands over to the numbered clauses.
The salutation is the first name, because the offer has been accepted and the working relationship has begun. “Dear Mr. Nair” would not be wrong; it is a matter of house style, and more traditional employers prefer it. What is wrong is “Dear Sir/Madam” on a letter that has just been addressed to a named person three lines above.
- 06
Clauses 1 and 2: place of work, and remuneration
Where the employee will work and whether they can be moved; what they will be paid, in what structure, and on what day.
Clause 1 names Gurugram as the initial place of posting and reserves the company’s right to transfer the employee to any of its offices in India, with reasonable notice, on the same terms. The three qualifiers are the clause. “Initial” signals that the posting can change. “Reasonable notice” is what stops the clause reading as a threat. “On the same terms” is what an employee actually wants to know, because a transfer that cuts pay is a different thing altogether. A company with one office can shorten this to a single sentence, but should still name the place of work, because it fixes which state’s rules the establishment works under.
Clause 2 states the cost to company as one annual figure, points to Annexure A for the structure, and says when salary is paid — the last working day of each month — and that statutory deductions apply. Keeping the breakdown in an annexure is a deliberate choice: the letter stays readable, and when the structure changes at the next revision only the annexure is reissued. What must be in the body is the total, the pay date and the fact of deductions, because those three are what an employee compares against the offer and, later, against a bank statement.
Where the company contributes to provident fund, or the employee is covered by state insurance, or gratuity will accrue, the letter above handles all of it in one phrase — subject to statutory deductions — and leaves the detail to the annexure and to the law. That is the right level for the letter. Reciting rates and thresholds in the body means the letter is wrong the day a rate changes; saying that statutory contributions and benefits apply as the law provides is always true, and it is what most companies do.
- 07
Clauses 3 and 4: probation and confirmation, hours and leave
How long probation lasts and how it ends; what a working week looks like and how much leave comes with it.
Clause 3 sets six months of probation and then says the thing most appointment letters leave out: confirmation will be communicated in writing, and the absence of a letter does not imply confirmation. Without that sentence a probation clause is ambiguous the day it expires — has the employee been confirmed by silence, or not? Employers have lost that argument in both directions. Say which it is. Six months is the common period in the Indian private sector for most roles; three months is common for junior or hourly positions, and a year is seen in some senior ones. If the company may extend probation, the letter should say so and cap the extension.
Clause 4 gives the standard hours, the working days and the annual leave entitlement, credited pro rata, under the company’s leave policy. The figures in the letter above are illustrative of a reasonable white-collar policy, not a statutory minimum; what the law requires varies with the kind of establishment and the state, and the policy is where it is spelled out. The words “under the company’s leave policy” are what keep the letter honest when the policy is revised. Pro rata crediting is worth stating because a new joiner in October will otherwise assume a full year’s leave is waiting.
- 08
Clauses 5 and 6: notice and termination, confidentiality — and what is left out
How either side ends the appointment, and what the employee is bound to about the company’s information. Also the clauses the letter above deliberately leaves to other documents.
Clause 5 gives a shorter notice period during probation and a longer one after confirmation, allows salary in lieu of notice, and reserves termination without notice for proven misconduct. Three features are worth copying. The notice is mutual — either party — which is both fairer and easier to rely on than a one-sided clause. Salary in lieu is stated, so neither side has to guess whether buying out notice is allowed. And the misconduct exception says “proven”, which commits the company to a process rather than an accusation. Notice periods of 30 to 90 days are common in the Indian private sector; anything longer needs a reason the employee would recognise.
Clause 6 does not set out the confidentiality and intellectual property terms. It says the employee will sign the company’s agreement on joining and that the agreement forms part of these terms. That is the right pattern for anything long enough to be its own document: refer to it, incorporate it, do not paste it. The same approach works for a code of conduct, an IT usage policy or a travel policy. A company that wants a conduct clause in the letter should write one sentence — that the employee will abide by the company’s policies as issued and amended from time to time — and leave the policies themselves to the handbook.
Two things some templates include and this letter does not: a non-compete that runs after employment ends, and an “at will” termination line. Post-employment non-compete restrictions are generally treated as unenforceable in India, so a clause of that kind mostly tells a careful reader that the drafter copied a foreign template. Non-solicitation and confidentiality obligations that survive employment are a different matter and are commonly included. “At will” is an American doctrine; in India notice is the norm, and the letter above says so in clause 5.
- 09
The acceptance request and the signature
The closing paragraph asks for the signed duplicate; the signature block says who the company is speaking through.
The letter above ends by asking Aarav to sign the duplicate copy as his acceptance and return it to Human Resources within seven days. That returned duplicate is the contract. The original in the employee’s hands is the company’s statement of terms; the duplicate with his signature on it is the evidence that he agreed to them. It goes on his personnel file — paper or scanned — and stays there for the life of the employment and for as long afterwards as the company keeps such records. An appointment letter with no signed duplicate on file is a promise, not an agreement.
The signatory is the Head of Human Resources, over the company’s name. Who signs is a question of authority, not seniority. The person should be one the company has authorised to appoint — usually the head of HR, a director or the proprietor — and the same person or role should sign the offer, the appointment and, later, the experience letter. In a small firm that is the owner. Type the name and designation under the signature, because a signature alone tells the reader nothing in three years’ time. Some companies add a seal beside the signature; that is house practice, not a requirement.
The one-line welcome before the sign-off is the only warmth in a letter of terms, and it is enough. The appointment letter is not the place for a paragraph about culture or mission; that was the offer letter’s job, and it will be the manager’s job on the first morning.
When the letter changes shape
The six clauses stay. What changes is how they are filled in, and occasionally who issues the letter and what it is called.
Probationary appointment
Most Indian appointment letters are probationary appointments, including the one above, so the change here is emphasis rather than structure. A letter for a role where probation is the whole point — a junior hire the company genuinely may not keep — should say how performance during probation will be assessed and by when the decision will be communicated, and may provide for one extension of probation, stated as a maximum. What it should not do is use probation to postpone every other term. The pay, the hours and the leave apply from the first day, and the letter should say so rather than implying that they begin at confirmation.
Fixed-term or contract appointment
A fixed-term appointment replaces the open-ended appointment sentence with a start date and an end date, and replaces the probation clause with a sentence on whether the term can be renewed and how. The notice clause commonly shortens, and the letter should say what happens if the work finishes early — whether the employee is paid to the end of the term, or notice applies. Fixed-term employees are, in practice, entitled to the same conditions as permanent staff doing the same work for the duration of the term, and the letter reads better if it says so than if it hopes nobody asks. The word to avoid is “consultant” for a person who keeps office hours and reports to a manager: that is an employee on a fixed term, and calling them something else does not change it.
Part-time appointment
A part-time appointment letter has to be exact about the thing a full-time letter takes for granted: the hours. Clause 4 becomes the working schedule — which days, which hours, or a total of hours a week and how they are agreed — and clause 2 states the pay in terms that match, whether a monthly figure for the agreed hours or an hourly rate with a minimum. Leave is stated pro rata to the hours worked. The letter should also say whether the employee may take other work, because a part-time appointment that silently forbids it is exactly the kind of thing that ends in a dispute. Everything else — place of work, notice, confidentiality — reads the same as the full-time letter.
School or college teacher appointment
A teacher’s appointment letter is issued by the management — the trust, society or company that runs the institution — and signed by its secretary or by the principal on its behalf, so the letterhead names the institution and the signature block names the management. The term is usually expressed in academic years, probation as one or two academic years, and the notice clause is written around the session: commonly, notice that would end during the academic year is not accepted without the management’s consent, so that a class is not left without a teacher in February. The letter should state the subject and classes to be taught, the pay scale the management follows, and any approval by the education authority the appointment is subject to, which applies to aided institutions and varies by state and board.
Appointment after promotion or transfer
When an existing employee is promoted or transferred, the company has two choices: a fresh appointment letter that restates all the terms with the new designation and pay, or a short addendum that changes only the affected clauses and says that everything else in the original letter continues. Most companies use the addendum — a promotion letter or a transfer letter — because it keeps the original appointment date and the original file intact. A fresh letter is the right choice when the change is large enough that the old letter no longer describes the job: a move from a fixed-term to a permanent appointment, or from part-time to full-time. Whichever is used, the employee signs a duplicate of it just as they did the first time, and both letters stay on the file.
Government-style appointment order
A government appointment is made by an order, not a letter, and the difference is instructive. The order names the post and the pay level in the government’s pay matrix rather than a negotiated figure, refers to the recruitment rules and the selection it follows from, commonly sets probation at two years, and makes joining conditional on a medical fitness certificate, verification of character and antecedents, and the submission of a joining report by a fixed date. The private-sector letter above has none of that machinery because it does not need it: pay is agreed rather than scheduled, and the conditions of joining were dealt with in the offer. What the private letter can borrow is the habit of naming the exact documents to be produced on the first day, and the deadline for producing them.
Offer letter versus appointment letter, said plainly
The offer letter proposes; the appointment letter records. An offer letter is sent before the candidate has committed. It names the post, the pay, the joining date and the conditions on which the offer stands, and it asks for acceptance by a date. It can be declined, negotiated or withdrawn, and it is conditional on things the company has not yet checked — certificates, a relieving letter, a background check. Once it is accepted and those conditions are met, the appointment letter is issued. It does not ask the employee to decide anything; it tells them what has been agreed, in full, and asks them to acknowledge it.
That is why the appointment letter is longer and duller than the offer. The offer that preceded the letter above ran to a few paragraphs and sold the role a little; the appointment letter runs to six numbered clauses and sells nothing. Some companies collapse the two into a single “offer cum appointment letter”, especially for small teams. It works when the hire is simple, but it asks the candidate to accept terms they have not seen in full before the checks are done, and it leaves the company without a document to withhold if a check fails. Two letters, two weeks apart, is the cleaner practice.
Where the two differ, the appointment letter governs, because it is the later document and the one the employee signed. That is exactly why it must not quietly differ from the offer in a way the employee did not agree to. If the terms have genuinely changed between offer and appointment — a different grade, a revised variable — say so in the letter and take the acceptance on those terms, rather than hoping the difference goes unnoticed until it matters.
Letterhead, signature and the personnel file
The appointment letter is the one document in the employment file that has to be signed by both sides, and it is commonly the one that is missing when a dispute arrives. The practice that prevents that is simple. Print two copies on letterhead. The authorised signatory signs both. The employee keeps one and signs the other, writing “Accepted” with the date, and returns it to HR by the deadline in the letter. HR scans the signed duplicate into the personnel file and keeps the paper. Nothing about this needs a system; a folder per employee does it.
Who may sign for the company is worth settling once, in writing, rather than every time somebody joins. In a private limited company it is commonly the head of HR or a director; in a partnership or proprietorship it is a partner or the proprietor; in a school it is the secretary or chairman of the management, or the principal where the management has authorised it. The same authority should sign the appointment and, years later, the experience and relieving letters, so that the file tells one consistent story about who spoke for the company.
Email is fine for delivery and is not a substitute for signature. Sending the appointment letter as a PDF, with a request to print, sign and return a scanned copy — or to sign electronically where the company has set that up — is normal practice now. What does not work is treating an email that says the letter is attached, with no reply, as acceptance. If the duplicate has not come back, chase it, and do not let the first pay run go out without it.
Length, tone and the annexures
The letter above is about a page and a half of A4, and that is right for a standard appointment. Six to eight clauses is normal; twelve is a sign that policies have been pasted in which should have been incorporated by reference. The test for any sentence is whether an employee would need to know it to understand what they have agreed to. If it is there to protect the company against a scenario the employee will never encounter, it belongs in the handbook or in the separate agreement, not in the letter.
The tone is formal and neutral. No exclamation marks, no “we are thrilled”, no capitalised Defined Terms that make a letter read as a contract drafted by somebody who wanted it to look like one. Numbered clauses with short bold headings, as above, are the convention because they let a reader find the notice period in five seconds. Short sentences and the active voice — “the company may transfer you”, not “you may be liable to be transferred” — make the letter both kinder and harder to misread.
Annexures carry what is long or changeable: the salary structure, the list of documents to be produced on joining, sometimes a job description. Each annexure is titled, dated and referred to from the body, and the employee’s signature on the duplicate covers the annexures too, which is worth saying in the acceptance line. Keep the annexures with the letter on the file. A salary structure that has gone missing is the most common reason a company cannot answer a straightforward question about what it promised.
Where appointment letters go wrong
Terms that differ from the offer without saying so
A lower variable, a longer notice period or a different grade slipped in between offer and appointment starts the employment on a grievance, and the employee’s signature on a duplicate they did not compare against the offer does not settle it in practice.
Silence on how probation ends
A probation clause with no sentence about confirmation leaves both sides guessing in month seven. Say that confirmation is in writing and that silence does not confirm, or say that it does — but say something.
A foreign template’s clauses
Post-employment non-competes, “at will” termination and references to another country’s statutes turn up in Indian appointment letters more often than they should, and each tells a careful reader that nobody read the template before signing it.
No signed duplicate on file
An appointment letter the employee never signed and returned is a statement of the company’s intentions, not evidence of an agreement. Chase the duplicate before the first pay run, not after the first disagreement.
Back-dating a late letter
Dating the letter to the joining day because it was actually issued in month three creates a document that is provably false. Date it when it is signed and let the effective date inside carry the start of employment.
The salary structure in the body
Ten lines of basic, allowances and deductions in the letter itself make it unreadable and mean the whole letter is reissued at every revision. Total, pay date and deductions in the body; the structure in an annexure.
Signed by someone without authority
A team lead signing an appointment letter because HR was busy leaves the company unable to say who bound it. Settle once who signs, and have that person or role sign every time.
Questions people actually ask
Is an appointment letter mandatory in India?
In practice an employer in India should issue a written appointment letter to every employee, and the law increasingly says so directly: several state Shops and Establishments Acts have long required one, and the central labour codes make a written appointment letter a requirement for every employee as they come into force. Beyond the legal position, the appointment letter is the document both sides rely on for notice, pay and probation, so an employer without one has no record of what was agreed. Employees are entitled to ask for it and should not accept a payslip as a substitute.
What is the difference between an offer letter and an appointment letter?
An offer letter proposes employment and asks the candidate to accept it by a date; an appointment letter is issued after acceptance and records the full terms of the employment as agreed. The offer is conditional on checks the company has not yet done and can be withdrawn or negotiated; the appointment letter is the contract, signed by both sides, and where the two differ the appointment letter governs. Most companies issue them two to four weeks apart, with the appointment letter arriving on or shortly before the joining day.
When is an appointment letter issued?
An appointment letter is issued after the candidate has accepted the offer and the conditions attached to it — certificates, a relieving letter, a background check — have been met, which in practice means a week or two before the joining date or on the joining day itself. Issuing it before joining gives the employee time to read and return the signed duplicate before they start. Issuing it months after joining, which happens in small firms, is better than not issuing it at all, but the letter should carry the date it was actually signed and state the original date of joining inside.
What if an employer never issues an appointment letter?
An employee who has worked without an appointment letter is still an employee, and the terms of employment can be shown from other records — the offer letter, payslips, salary credits, emails about the role — but every one of those is a weaker document than a signed appointment letter, and each question about notice or leave becomes an argument. The first step is to ask HR for the letter in writing, referring to the offer and the joining date. If it is refused, keep the offer letter, the payslips and any written communication about terms together, because those become the record. The state labour department is the usual place to complain where an establishment is one the law requires to issue an appointment letter.
Can the terms in an appointment letter differ from the offer letter?
The terms in an appointment letter can differ from the offer letter, but only if the employee agrees to the changed terms, and a change slipped in without being pointed out is not an agreement in any practical sense. Where something has genuinely moved between offer and appointment — a grade, a variable component, a joining date — the appointment letter should say what changed, and the employee’s signature on the duplicate then covers the new terms. An employee who finds an undisclosed difference should raise it in writing before signing, because the appointment letter is the later document and will be read as governing.
Does an appointment letter need stamp paper or notarisation?
An appointment letter does not need to be on stamp paper or notarised; it is a letter on the company’s letterhead, signed by an authorised person, with a duplicate signed by the employee as acceptance. That is how most companies in India issue them, and in practice it is treated as a sufficient record of the terms. Some employers execute a separate employment agreement on stamp paper alongside the letter, usually for senior roles or where the confidentiality and intellectual property terms are elaborate; that is a matter of the company’s practice rather than a requirement for the letter itself.
What should an employee check before signing an appointment letter?
Before signing an appointment letter an employee should compare it line by line with the offer letter: the designation and grade, the cost to company and its structure in the annexure, the joining date, the probation period and how confirmation happens, the notice period during and after probation, and the place of work and transfer clause. Read the confidentiality or intellectual property agreement the letter refers to, because signing the letter commits you to signing that too. Anything that differs from the offer, or is unclear, should be raised in writing with HR before the duplicate goes back, and the copy you keep should stay with the offer letter and the annexures.
