Offer Letter vs Employment Contract: What Is Actually Binding
An offer letter is legally binding once you accept it: its designation, CTC, start date and reporting manager count as a contract under the Indian Contract Act, 1872. But it is rarely the whole deal, confidentiality, IP assignment, notice-period details and non-compete limits are usually missing, and Indian law voids post-employment non-competes under Section 27. Insist on a signed employment agreement before day one.
The Offer Letter Is a Promise, Not the Whole Deal
Most people treat the offer letter as the finish line. You get it, you're relieved, you sign and forget about it. But an offer letter is really just the starting handshake, a written record that the company intends to hire you on certain terms and that you've accepted. Under the Indian Contract Act, 1872, it usually satisfies the basic ingredients of a contract: offer, acceptance, and consideration (your salary in exchange for your work). So yes, the core commercial terms in an offer letter, designation, CTC, start date, reporting manager, are legally binding once you accept.
What it is not, in almost every case, is a complete employment contract. Offer letters from Indian startups are typically two pages, sometimes less. They tell you what you'll earn and when you start. They rarely tell you what happens if you want to leave early, who owns the code you write, what you're allowed to say about the company after you quit, or whether you can join a competitor next door.
Where the Gaps Actually Bite
Confidentiality is the first gap. A generic offer letter might have one line about "maintaining confidentiality of company information," which is too vague to hold up if there's ever a dispute about what counts as confidential or how long the obligation lasts. A proper employment agreement spells out what data, code, client lists, and processes are covered, and for how long after exit.
IP assignment is the second, and it matters more for startups than founders often realize. Under Section 17 of the Copyright Act, 1957, work created "in the course of employment" generally belongs to the employer by default, but this gets murky fast with interns, contractors, freelancers, or anyone paid on a retainer rather than a payroll. If your company has ever had a contractor build a feature without a written IP assignment clause, technically that contractor may still hold rights to it. A detailed employment or consulting agreement closes that gap explicitly instead of relying on a default that courts interpret narrowly.
Notice period is where most disputes actually land in practice. Offer letters often just say "30 days" or "90 days" without addressing what happens if the company wants to let you go without notice, whether they can pay you in lieu of notice, or what your last-working-day process looks like. Ambiguity here creates friction exactly when both sides are least willing to compromise.
Non-solicitation and non-compete clauses need the most care, because Indian law treats them very differently depending on timing. Section 27 of the Indian Contract Act makes any agreement that restrains a person from carrying on a lawful profession or trade void, with a narrow exception for the sale of business goodwill. Courts, going back to cases like the Supreme Court's ruling in Niranjan Shankar Golikari, have consistently held that a restriction can operate while you're still employed but cannot bind you after you leave. So a clause stopping you from joining a rival company for a year after resignation is generally unenforceable in India, no matter how confidently it's worded. A restriction on soliciting your former employer's clients or poaching colleagues during your notice period, though, tends to hold up much better.
What a Real Employment Agreement Should Cover
A proper agreement, separate from the offer letter, should walk through probation terms, appraisal cycles, grounds for termination, dispute resolution (arbitration clause or jurisdiction), stock options if any, and a clear IP assignment schedule listing what's being assigned and from when. If your offer letter is silent on all of this, that silence is not neutral. It usually means the terms default to whatever's least favourable to you when a disagreement actually comes up.
For founders drafting these documents and for employees signing them, the safest approach is to treat the offer letter as step one and insist on a signed employment agreement before your first day, not after. Stamp duty requirements for employment agreements vary by state, so it's worth confirming what applies to your specific location before finalising anything.
