Who signs a partnership firm or LLP cheque? Mandates, liability and the firm-name trap (2026)

The cheque was for ₹3,80,000, drawn on a fabrics firm's Axis current account, signed by the younger of the two partners — the same signature he'd put on everything for six years. It came back in three days. Memo reason: not drawn as per mandate. The account mandate, filed the week the account was opened and read by nobody since, said cheques above ₹2,00,000 need both partners' signatures.

Nothing was forged. Nothing was short. A fully funded cheque returned on a rule the firm itself had written, filed and forgotten.

If you run a private limited company, "who signs" is settled by a board resolution — the authorised signatory guide for companies covers that world. But most of Indian business is not a company. It's a proprietorship, a partnership firm or an LLP — and each of the three answers the signing question differently, with different paper behind it and very different consequences when a cheque bounces. This is the guide for those three.

Three entity types, three different answers

A proprietorship is the proprietor. Full stop. The law sees no gap between "Sharma Enterprises" and Mr Sharma — the firm name is a trading style, not a person. The account is legally the proprietor's, the signature is the proprietor's, and there is no delegating signing to a manager "by resolution", because there is no entity to pass one. A bank can register a mandate or power of attorney letting someone else operate the account, but that is the proprietor lending out his own authority — every rupee of liability stays personally his. The simplicity cuts both ways: nothing to file, and nothing standing between the firm's cheques and the owner's personal assets.

A partnership firm acts through its partners. The firm has a name, a PAN and an account, but under Indian partnership law it is not a separate legal person the way a company is. Each partner acts as an agent of the firm, and who may sign cheques is fixed by two documents working together: the partnership deed (what the partners agreed among themselves) and the account mandate (what the firm told the bank). When the two disagree — and they disagree more often than anyone admits — the counter follows the mandate.

An LLP is a separate legal person. Closer to a company than to a traditional firm. It exists independently of its partners, and it acts through its designated partners. The bank opens the account against the LLP agreement, the incorporation certificate and an authority resolution naming who operates it. The liability shield is real. It is also, as we'll get to, not absolute.

Three structures, one bank counter. And the counter cares about exactly one document. Hold that thought.

The firm-name trap

The most common signing mistake in firm banking isn't a wrong signature. It's the right signature in the wrong capacity.

The account is in the name "Shree Balaji Traders". The cheque comes in signed "R. Patel" — bare, personal style, nothing connecting the scrawl to the firm. Or the reverse: someone signs with a confident "for Shree Balaji Traders" and a rubber stamp, but that someone was never added to the mandate at all. Both cheques are funded. Both signatures are genuine. Banks return both — the first because a bare personal signature doesn't execute the firm's payment order, the second because the bank has no specimen on record for that hand, however grand the stamp.

The fix is boring and absolute. Sign exactly as the specimen filed in the mandate, in the same style, with the firm's name appearing with the signature — most printed cheques carry "For [firm name]" above the signature line, and you sign under it in your mandate capacity. Keep the signing style constant, too: a firm cheque returned for a signature mismatch costs exactly what a mandate breach costs, and it happens to partners who "modernised" their signature somewhere along the way. And the rest of the leaf — date, payee, amount in words — follows the same rules as any personal cheque; the field-by-field guide applies unchanged.

The mandate is the rulebook — "any one" vs "jointly by two"

Strip away the folder and what the bank actually holds against a firm account is short: the names of the authorised signatories, a specimen signature for each, and one operating instruction. That instruction is usually one of three:

• Any one, singly. Either partner alone can sign anything. Fastest daily operations, weakest control.
• Jointly by two. Every cheque needs a co-signer. Slower — and every rupee leaving the account gets four eyes.
• Hybrid. Singly up to a threshold, jointly above it — say, either partner alone up to ₹1,00,000, both partners above.

For most two- and three-partner firms the hybrid earns its keep. The monthly salary run, the rent cheque, the courier bill — one signature, no bottleneck. The ₹5,00,000 machinery advance — two signatures, deliberately. Most money disputes between partners begin with a cheque one of them didn't know about. A joint threshold is a great deal cheaper than that dispute.

One caution the counter will never give you: the bank enforces the mandate, not the deed. If the deed says purchases above ₹2,00,000 need both partners' consent but the mandate says "any one singly", the bank will clear a ₹4,00,000 cheque signed alone without blinking. The deed breach is a fight between the partners. The bank was never in it.

When a partner leaves, dies or joins

This is the section most firms get wrong, because everything else about a partner's exit has a ceremony — the retirement deed, the MCA filing for an LLP, the farewell dinner — and the bank mandate has none. It does not update itself. Until the firm files a fresh mandate, the departed partner's signature still clears cheques, and the incoming partner's signature bounces them.

The sequence that works:

1. Revise the mandate first. The letter (in the bank's format, signed the way the bank requires) goes in before the next cheque is signed under the new arrangement. Not after. Same rule for an added partner: no signing until the specimen is on record.
2. Hunt down leaves signed in advance. Cheques the outgoing partner signed under the old mandate — post-dated cheques to a lender, blank-signed leaves kept "for emergencies" — are now live problems. Decide, leaf by leaf, whether each should still be presented, and replace the ones that shouldn't. A cheque signed by someone who has since exited invites questions you don't want asked at a clearing desk.
3. Count the unused books. Every cheque book issued on the account, accounted for, physically. A book that was in the departed partner's drawer needs to come back; if one can't be traced, tell the bank and stop the series. Fresh books under the new mandate can be ordered online in minutes.

Death is the harder case. On notice of a partner's death, banks generally hold operations on the account until fresh instructions come from the surviving partners — so a firm that waits to inform the bank "until things settle" is quietly running on a mandate that no longer works. Inform early; restructure the mandate immediately.

Who pays when a firm cheque bounces

Now the part that separates the three structures for real: a firm cheque returns unpaid against a due debt, and Section 138 of the NI Act enters the room. Who is standing there?

Proprietorship: the proprietor, alone and entirely. There is no firm to hide behind, because there is no firm — the "firm's" cheque was always the proprietor's cheque.

Partnership firm: the NI Act's provisions on offences by companies extend to firms — the firm can be prosecuted, and so can partners who were in charge of and responsible for the conduct of its business when the cheque was issued. And the exposure doesn't stop at the criminal complaint: partnership law makes partners jointly and severally liable for the firm's obligations, so the payee can come after a partner's personal assets for the firm's debt. A company director almost never faces that for a company's dues. A partner can.

LLP: the shield is real — a partner is not personally liable for the LLP's debts merely for being a partner. But the shield protects against the debt, not against having signed the cheque: the signatory of the bounced cheque and those responsible for the conduct of the business at the time can still face Section 138 proceedings personally. Limited liability was never a licence to bounce cheques.

This is general information, not legal advice. If a firm cheque of yours has actually been returned against a debt, the Section 138 clock runs on short, unforgiving deadlines — talk to a lawyer this week, not this quarter.

The bank doesn't read your partnership deed at the counter — it reads the mandate. Whatever the deed says about who runs the firm, the only signature rule that clears or returns a cheque is the one sitting in the bank's records. Keep that document current, and half of firm-cheque trouble never happens.

An operating checklist for firm cheques

Five habits, none of them expensive:

• A copy of the current mandate in the firm's own file — not just the bank's. Half the firms that bounce a cheque on "not drawn as per mandate" couldn't say what their mandate was.
• Specimen discipline. Signatures drift over years. If a signatory's everyday signature has wandered from the filed specimen, refresh the specimen at the bank before the drift bounces something.
• Custody separation. The cheque book lives with someone who is not a signatory — the accountant holds the leaves, the partner holds the pen. One person holding both is how blank-signed leaves happen.
• A register of every cheque issued in the firm's name — number, date, payee, amount, who signed, current status. When a partner asks "what did we pay Mehta & Sons in March?", the answer should take seconds. That register is exactly what cheque lifecycle tracking is — issue to clearance, per leaf.
• Print, don't handwrite, the fixed fields. Payee, amount in figures, amount in words, date — printed cleanly, leaving only the signature line for the humans the mandate names. Fewer handwritten fields, fewer return reasons.

That last habit is where software quietly does the compliance work for you. The signature stays exactly where the law and the mandate put it — with the partners. Everything else on the leaf stops being a place to make mistakes.
