Founders' Agreement vs SHA vs LLP Agreement: Which One Do You Actually Need?

If you've started reading about founder-relationship documents in India, you've probably run into three names — founders' agreement, Shareholders' Agreement (SHA), and LLP Agreement — used almost interchangeably. They're not interchangeable. Each one has a different legal basis, a different filing status, different signatories, and gets signed at a different point in your company's life. Confusing them is the single most common mistake founders make when they assume one document already covers what the others are meant to cover.

What a Founders' Agreement Actually Is, Legally

A founders' agreement is a private contract between the founders of a company, drawing its legal validity from Section 10 of the Indian Contract Act, 1872 — the same general contract law that governs any binding agreement between parties with the capacity to contract. It is not a statutory filing. No government authority reviews it, approves it, or requires it as a precondition to incorporation. That's precisely why it's easy to skip — nothing forces you to sign one before your company or LLP exists.

Founders' Agreement vs Shareholders' Agreement vs LLP Agreement

These three documents differ on every axis that matters — legal basis, whether they're filed with the MCA, who signs them, when they're signed, and what they actually govern:

Two things fall out of this table immediately. First: if you've formed an LLP and filed your LLP Agreement, that filing has nothing to say about vesting, IP assignment, or what happens if a founder walks away early — an LLP Agreement is a statutory governance document, not a founder-relationship document. Second: an SHA usually doesn't exist yet for an early-stage company — it typically shows up at the first funding round, which can be a year or more after the founders started working together. A founders' agreement is the document that fills that gap.

Why 'We Filed Our LLP Agreement / AoA' Doesn't Mean Founder Terms Are Covered

For LLPs specifically: the LLP Agreement is not replaced by a founders' agreement, and a founders' agreement doesn't replace the LLP Agreement either. The LLP Agreement is a statutory document — every LLP must file one as Form 3 under Section 23 of the LLP Act 2008, and it governs contributions, profit-sharing, and duties between designated partners. A founders' agreement for LLP designated partners sits alongside it as a supplementary private contract, covering things the statutory LLP Agreement typically doesn't — vesting schedules, IP assignment language, and deadlock mechanics between the founders specifically.

For Private Limited companies, the equivalent gap is between your Articles of Association (AoA) and a founders' agreement. Filing your AoA at incorporation sets up the company's constitutional rules, but it doesn't automatically encode founder-specific terms like a vesting/buyback schedule or a deadlock clause unless those terms are separately mirrored in.

When to Sign One: Pre-Incorporation, at Incorporation, or Later

• Pre-incorporation — the safest point, especially if any founder is writing code, designs, or content before the company legally exists (see our guide on the pre-incorporation IP trap)
• At incorporation — the next-best point, timed alongside your LLP Agreement or AoA filing
• Later, at funding — the riskiest point to sign your first founder document, since by then equity, IP, and role disputes may already be baked in and harder to renegotiate cleanly

The Enforceability Limit Founders Miss

In practice, this means a founders' agreement is necessary but not always sufficient. If a clause needs to be enforceable against the company itself — not just between the founders personally — it needs a corresponding provision in the AoA (for a Pvt Ltd) or the LLP Agreement (for an LLP).

What a Founders' Agreement Should Cover

A complete founders' agreement typically addresses roles and responsibilities, equity split, a vesting schedule (which works differently in India than the US — see our guide on founder vesting), an IP assignment clause (see the pre-incorporation IP trap), confidentiality, a narrowly-scoped non-solicitation clause, a deadlock/exit mechanism for even splits (see our guide on deadlock clauses), governing law, and dispute resolution.
