Governing Indian Law & Statutory Authority
Quick answer
An offer letter states the role, the compensation and the key conditions, and asks for acceptance. Once the candidate accepts, an agreement exists, and the terms that were in the offer are the terms that bind. An appointment letter is issued after acceptance and sets out the full terms, including the matters the offer letter deliberately left short. Where only one document is used, it should be the fuller one. Neither document is compulsorily registrable, and neither is in the First Schedule to the Information Technology Act, 2000, so both can be e-signed. Whether an appointment letter attracts stamp duty depends on the state and on how the document is framed, because an appointment letter that operates as a contract of employment is categorised differently from a bare letter of appointment.
An offer letter and an appointment letter are often treated as the same piece of paper with two names. They are not, and the difference matters the moment a candidate accepts and then does not join, or joins and then discovers that the terms are not what they believed. An offer letter is an invitation that becomes a contract on acceptance. An appointment letter is the formal record of the terms on which the person is actually engaged. Some employers use only one document, some use both in sequence, and both are legally workable. What causes trouble is using a short informal offer letter as though it were the whole contract, and then relying later on terms that were never in it. Both documents are ordinary commercial instruments, not documents in the First Schedule to the Information Technology Act, 2000, which means both can be issued, accepted and signed electronically. This guide covers what each document does, what makes an offer binding, which clauses decide the relationship, the stamping position, and how the whole sequence is completed online.

Offer letter, appointment letter, and employment agreement: three different jobs
The three documents sit at different points in the same sequence, and confusing them is the source of most of the problems in this area. An offer letter is short by design. It identifies the role and designation, the reporting line, the location, the compensation and the date by which the offer lapses, and it asks the candidate to confirm acceptance. It is written to be read in two minutes and answered the same day. An appointment letter is issued once the candidate has accepted. It confirms the date of joining and sets out the terms that actually govern the relationship: the duties, the working hours and place of work, the compensation structure and its components, the probation period and how it is confirmed, the notice period on both sides, confidentiality and intellectual property obligations, the policy documents that are incorporated by reference, and the circumstances in which the engagement may be terminated. An employment agreement, which the library covers separately, is the fuller contract used where the parties want a negotiated document rather than a letter. Many Indian employers use an appointment letter in place of a full agreement, which works, provided the appointment letter actually contains the clauses that matter instead of referring vaguely to "company policy". A reference to a policy is only as good as the policy's existence, its version control, and whether the employee was given it.
When an offer letter becomes legally binding
The Indian Contract Act, 1872 governs this, and the analysis is straightforward. An offer is a proposal under Section 2(a). Acceptance under Section 2(b) turns the proposal into a promise. Section 10 then asks whether the agreement is a contract: free consent, competent parties, lawful consideration and a lawful object. Applied to hiring, the effect is that a clear offer accepted without qualification on the terms stated becomes a binding contract. Communication of acceptance matters: under the Act, acceptance must be absolute and unqualified, and a purported acceptance that varies the terms is a counter-offer, not an acceptance. This is exactly what happens when a candidate replies to an offer letter with a request for a higher salary or a later joining date, and the employer treats the reply as an acceptance without answering the change. Two situations deserve drafting attention. The first is the conditional offer. Where the engagement depends on background verification, reference checks, production of documents, a medical examination or a qualification, the offer letter must say so expressly and must say what happens if the condition is not met. An offer that is silent on conditions is difficult to withdraw once accepted. The second is the candidate who accepts and does not join. Indian courts do not generally grant specific performance of a contract of personal service, so an employer cannot compel a person to work. The remedies that are practically available are the recovery of demonstrated losses, and, more usefully, a clear notice obligation and an express statement that the offer is subject to satisfactory verification. Whether a court awards damages for a candidate who does not join depends on proof of loss, which is why the practical protection is not a penalty clause but a properly drafted condition and notice provision.
The clauses that decide the arguments
Compensation structure. The letter should break the cost to company into its components rather than stating a single figure, because the components determine statutory contributions and the treatment of variable pay. Whether a bonus is discretionary or guaranteed should be stated, not implied. Probation and confirmation. State the length of probation, whether it can be extended, the notice during probation, and whether confirmation is automatic or requires a positive act. An indefinite probation with an unstated consequence is a recurring dispute. Notice period and its interaction with the offer. The notice period is the clause most likely to be litigated on exit. It should state the notice required from each side separately, whether the employer may pay in lieu, and how leave and dues are settled. Confidentiality and intellectual property. Employment agreements in India frequently omit a clear assignment of intellectual property, relying instead on the default position in copyright law that work created in the course of employment belongs to the employer. That default does not cover everything, particularly where the work is created outside ordinary duties or where the relationship is later characterised differently. An express assignment clause is inexpensive and removes the argument. The library covers the surrounding issues in its guide on intellectual property ownership in service contracts. Restrictive covenants. Post-employment non-compete restraints run into Section 27 of the Indian Contract Act, 1872, which renders agreements in restraint of trade void, and Indian courts read that section strictly. Confidentiality obligations and reasonable non-solicitation covenants travel considerably further than a broad non-compete. A letter that threatens a non-compete it cannot enforce is worse than one that relies on the clauses that work. Termination. Distinguish termination for cause from termination without cause, and set out what each requires. Employees in the categories covered by standing orders or by the Industrial Disputes Act, 1947 framework, and in states with Shops and Establishments legislation, may have statutory procedural protections that a letter cannot contract out of.
Is an offer letter or appointment letter stamped?
This is where templates mislead. An offer letter is normally not stamped, and in most states it does not attract stamp duty, because it is a communication of a proposal rather than an instrument creating an obligation. An appointment letter is a different question. Under the stamp legislation of several states, the article applicable to an "agreement" or to a "contract of employment" can apply where the letter actually operates as the contract of service, as distinct from a simple letter of appointment which is often treated as exempt or as attracting only nominal duty. The framing of the document therefore affects the analysis, and the position differs from state to state. The practical approach is to identify the category of the instrument and the applicable state before issuing the letter, and to confirm the current position rather than relying on a figure from an older template. Where duty applies, it is usually modest, and the cost of getting it wrong is the admissibility problem in Section 35 of the Indian Stamp Act, 1899, which arises at exactly the moment a dispute is being argued.
Issuing and signing both letters online
Neither document is compulsorily registrable, neither requires notarisation, and neither appears in the First Schedule to the Information Technology Act, 2000. Both can therefore be issued and signed electronically, end to end. The sequence that works: the letter is prepared as a digital document; it is routed to the candidate for acceptance using Aadhaar-based eSign, so that the acceptance is attributable and timestamped; where the state position requires stamping, an e-stamp certificate is obtained before the letter is issued; and the signed copy is returned automatically to both sides together with the signature certificate and the audit trail. The practical gains are specific rather than general. Remote candidates can accept on the day the offer is made instead of waiting for a courier. The audit trail records who accepted, when and from where, which removes the argument about whether an acceptance was communicated. And the countersigned copy is filed with its evidence intact rather than as a scan of a scan. The party who must act personally is the candidate, who signs the acceptance in their own name, and the employer's authorised signatory, whose authority to issue the letter should be clear. Where the letter incorporates policy documents, those documents must be attached in the version that applies on the date of issue. A common failure is to e-sign an appointment letter that refers to a policy nobody has sent.
What goes wrong most often
The offer letter that contains everything. Employers sometimes put the entire contract into the offer letter, including restrictive covenants, and then issue a separate appointment letter with different wording. Two documents with inconsistent terms create an argument about which prevails. If both are used, the appointment letter should say expressly that it supersedes the offer letter except as to the terms it repeats. The unstated condition. An offer made subject to verification, where the verification condition is never written down, becomes difficult to withdraw after acceptance. The acceptance that was a counter-offer. A candidate's email asking for a changed joining date is not an acceptance of the original offer. If the employer does not answer it and treats it as accepted, there is no contract on the original terms, and possibly no contract at all. The policy incorporated by reference but never supplied. The reference should identify the policy by name and date, and the policy should be attached. The restrictive covenant that will not hold. Broad post-employment non-competes are read against the employer under Section 27. A letter that leads an employer to believe it has protection it does not have is a liability, not an asset.
When to obtain a review
A review is especially useful when…
- — You are hiring remotely and want the offer accepted and recorded without a courier
- — Your current offer letter is silent on conditions, probation or verification
- — You are relying on a non-compete clause that may not be enforceable
- — You need the appointment letter, policy documents and acceptance record filed together
