One Heir Didn't Sign the Sale Deed: Is the Sale Valid for the Others' Shares?

One of the legal heirs did not sign the sale deed. The seller says the others signing is enough, and the sub-registrar accepted the document, so the sale must be complete. It is one of the most common questions buyers of inherited or resale property in India ask, and the confident answers they get on forums ("the deed is void", "the registrar will never register it") are usually wrong in a way that costs money.

Here is what the law actually says, and how to check it before you pay.

In short (2026)

No, a sale deed signed by only some of the legal heirs does not sell you the whole property. It is valid only for the shares of the heirs who actually signed. This is the "pro tanto" rule under Section 44 of the Transfer of Property Act, 1882, and the Supreme Court applied it directly in Sk. Golam Lalchand v. Nandu Lal Shaw (2024 INSC 676): a co-owner who sells the "entire" jointly owned property without the other heirs joining conveys only his own undivided share. The non-signing heir's share is untouched. So as a buyer you acquire an undivided fractional interest, not a clean, exclusive, marketable title, and your only route to a specific portion is a partition suit.

The deed is not automatically "void", and a sub-registrar can and often will register it anyway (K. Gopi v. Sub-Registrar, 2025 INSC 462, held the registering officer has no power to check the seller's title). That is precisely why the fact that a deed was registered never proves that every co-owner signed it.

Is the sale valid if one of the legal heirs did not sign?

The honest answer is: partly. A sale is not an all-or-nothing event when several people co-own the property.

When a person dies without a will, the property does not pass to one "family representative". It passes to all the legal heirs together, each holding a defined share. Each heir can deal only with their own share. Section 7 of the Transfer of Property Act allows a person to transfer only property that is his, or that he is authorised to dispose of. An heir who signs the deed is authorised to convey his own share. He is not authorised to convey a co-heir's share unless that co-heir has given him a registered power of attorney or has signed too.

So when four of five heirs sign a deed that purports to sell the whole property:

• The four signing heirs validly transfer their four shares.
• The fifth heir's share is not transferred at all. It stays with that heir exactly as before.
• The deed is "valid to the extent of" the signing heirs' shares, and inoperative for the rest.

This is not a loophole or a technicality. It is the settled rule the Supreme Court restated in 2024 (see below).

What did you actually buy if only some heirs signed?

You bought an undivided share, not a demarcated plot.

Section 44 of the Transfer of Property Act says that when one co-owner transfers his share, the buyer steps into that co-owner's shoes: he gets the transferor's right to joint possession and the right to enforce a partition, subject to the same conditions that bound the seller. He does not get a fenced-off portion he can occupy to the exclusion of everyone else.

In Sk. Golam Lalchand v. Nandu Lal Shaw (2024 INSC 676, decided 10 September 2024), a property jointly owned by two brothers since 1959 devolved on many heirs on both sides. One heir, Brij Mohan, alone sold the whole property in 2006 without the others joining. The Supreme Court held that he "was not competent to transfer the entire property without getting his share determined and demarcated", and that the sale deed, in accordance with Section 44, "may be a valid document to the extent of the share of Brij Mohan". The buyer's remedy, the Court said, was to claim relief "either by suit of partition or by suit of compensation and damages".

Read that carefully, because it is the whole point. The buyer did not lose everything. He also did not get what he paid for. He got one man's undivided share and a lawsuit.

For you as a buyer that means, until a partition is worked out:

• You cannot get exclusive possession of the property.
• You cannot get the whole property mutated into your name in the revenue or municipal records.
• The omitted heir can independently sue to protect their share, and you inherit that dispute.

But the deed got registered. Doesn't that make my title complete?

This is the myth that traps most buyers. Registration and title are two different things.

Registration proves that a document was executed and formally recorded. It does not prove that the person who signed actually owned what he sold. In K. Gopi v. The Sub-Registrar (2025 INSC 462, decided 7 April 2025), the Supreme Court struck down a state rule that had let sub-registrars refuse documents on title grounds, holding that "the registering officer is not concerned with the title held by the executant" and "has no adjudicatory power to decide whether the executant has any title". Even a seller with no title at all can get a deed registered if the paperwork is in order.

The companion rule runs the other way. In Suraj Lamp & Industries v. State of Haryana ((2012) 1 SCC 656), the Supreme Court held that power-of-attorney "sales", agreements to sell and wills do not by themselves transfer title, and that a proper registered conveyance is necessary. So registration is necessary, but it is not sufficient. "My deed is registered" answers only the question of formality. It says nothing about whether every co-owner signed, which is exactly the question a missing-heir problem raises.

Who counts as a legal heir who must sign?

The answer depends on how the property was held, and this is where sellers, and even some agents, get it wrong.

Self-acquired property, owner died without a will. Where the deceased was a Hindu man, the property devolves on the Class I heirs under Section 8 of the Hindu Succession Act, 1956 (other personal laws set their own heirs and shares). Section 10 fixes each heir's share, and Section 19 says two or more heirs take "as tenants-in-common and not as joint tenants", per capita. Translation: each heir holds a fixed, ascertainable fraction from the day the owner died. Four of five equal Class I heirs signing a deed for a self-acquired flat convey exactly four-fifths, no more. A common seller line, "it was self-acquired, so the other heirs need not sign", is only half true: it is self-acquired for the deceased, but on intestacy all his Class I heirs now co-own it, and they all must sign to sell the whole.

Undivided joint family (coparcenary) property. Here shares are notional and fluctuate until an actual partition, so the "missing share" is not even a fixed number until partition is worked out. A single coparcener still cannot sell the whole.

If you want the full map of who inherits in each situation, our guide to the Hindu Succession Act and property rights of heirs sets it out. If the family "divided" the property informally years ago with no registered partition deed, read No registered partition deed: can the heirs sell, and is the title safe to buy? first, because an oral partition changes what each person can sign for.

The daughter nobody included

The single most common "we forgot someone" gap is a married or estranged daughter.

Since the 2005 amendment to the Hindu Succession Act, a daughter is a coparcener by birth in her own right, in the same manner as a son. The Supreme Court settled this in Vineeta Sharma v. Rakesh Sharma ((2020) 9 SCC 1), holding it applies whether the daughter was born before or after 2005 and regardless of whether the father was alive on the amendment date. For self-acquired property, Arunachala Gounder v. Ponnusamy (2022 LiveLaw (SC) 71) confirmed that a daughter inherits her father's self-acquired property as a Class I heir in preference to collaterals.

A married daughter who moved to another city, a daughter the brothers "settled" verbally, or a daughter nobody thought to consult is a legal heir with a real, enforceable share. If her signature is missing, her share is unsold, and she can assert it. Our explainer on why a decades-old family partition can unwind a purchase covers this specific risk in detail.

What if one of the heirs was a minor?

If one of the heirs was under 18 when the deed was executed and a parent signed "on the minor's behalf", that portion of the sale sits on a fuse.

Section 8 of the Hindu Minority and Guardianship Act, 1956 says a natural guardian cannot sell, mortgage or gift a minor's immovable property without the previous permission of the court, and permission is given only for the minor's necessity or evident advantage. A sale made without that permission is not void outright. It is voidable at the instance of the minor, who can move to set it aside, typically within three years of turning 18. Section 29 of the Guardians and Wards Act, 1890 applies the same rule to a court-appointed guardian. So a deed that looks fully signed can still be undone years later if one of those signatures was a parent signing for a child without a court order.

The special trap for a family dwelling house

There is a further limit that catches buyers of a family home specifically. The second paragraph of Section 44 of the Transfer of Property Act says that where the buyer of a share in a dwelling house belonging to an undivided family is not himself a member of that family, he is not entitled to joint possession or common enjoyment of the house.

In plain terms: if you buy one heir's undivided share in the family house, you may not even be able to move in alongside the others. Your right is a right to a share in value, realised only through a partition suit. It is one of the sharpest reasons an outside buyer should never accept a part-signed deed on a family residence.

How a clean deal is actually done

The problem is entirely fixable before you pay. There are four legitimate routes, and one thing sellers wave around that usually does not work.

1. Every heir signs the sale deed as an executant. This is the clean default. If an heir cannot attend, they can execute a registered special power of attorney authorising someone to sign for their share.
2. The omitted heir executes a registered release or relinquishment deed in favour of the other heirs or the buyer, before or alongside the sale. This must be registered. Section 17 of the Registration Act, 1908 makes any instrument that extinguishes a right in immovable property compulsorily registrable, and an unregistered release does not by itself give up the heir's share.
3. A minor's share needs prior permission of the court under Section 8 of the Hindu Minority and Guardianship Act (or Section 29 of the Guardians and Wards Act). No court order, no valid sale of that share.
4. A genuine, registered partition that first splits the property into demarcated portions, so the seller is selling a specific piece he now solely owns.

The thing that usually does not work: an unregistered "family settlement" paper produced to explain away a missing signature. In Kale v. Deputy Director of Consolidation ((1976) 3 SCC 119), the Supreme Court held that a document merely recording a family arrangement that had already happened can be an unregistered memorandum, but a document that itself creates or declares the division for the first time must be registered under Section 17. A settlement letter that "divides" the property, rather than recording a completed and independent division, does not convey title on its own.

Why the encumbrance certificate will not warn you

Here is the gap that a routine document check misses. An encumbrance certificate (EC), issued under the Registration Act, is built from the register of documents actually presented for registration. It lists the registered instruments affecting a property, with the executants named on each. It is not a document of title.

So the EC will faithfully show the sale deed and list the heirs who signed. It will not tell you that the seller had three sisters and a set of cousins who were co-heirs and never signed. Catching a missing heir is a different exercise from pulling an EC. It means reconstructing the family tree from death certificates, a legal-heir or succession certificate, and birth or marriage records for daughters, then cross-checking every heir against who actually executed each deed across the full ownership chain, typically 30 years, not just the most recent transaction. Our guide on how to read an encumbrance certificate explains what the EC does and does not capture, and how to read a sale deed before buying shows where the executants and recitals sit in the document itself.

What to do before you pay

• Get the full list of legal heirs of every deceased owner in the chain, proved by a legal-heir or succession certificate, not the seller's word.
• Match every named heir against the signatures on the sale deed and on each earlier deed in the chain. Look specifically for married daughters, heirs of a pre-deceased son or daughter, and anyone who was a minor at the time.
• If a heir did not sign, insist on either their joining the deed or a registered release deed from them before any advance changes hands.
• Remember your exposure window. In Shanti Devi v. Jagan Devi (2025 INSC 1105, decided 12 September 2025), the Supreme Court confirmed that a co-sharer whose signature was never on a deed can sue for possession of their share within twelve years of the buyer's possession turning adverse to them, without even having to formally cancel the deed. A part-signed deal can be challenged for a long time after you buy.
• Run a full title search that reconstructs the heirship, not just an EC download. This is exactly the kind of defect a proper 30-year title search report is designed to surface, and the reason a clean EC is never the end of the enquiry.

Frequently asked questions

If one heir did not sign, is the whole sale deed void? No. It is valid for the shares of the heirs who did sign, and inoperative for the share of the heir who did not. The Supreme Court in Sk. Golam Lalchand v. Nandu Lal Shaw (2024 INSC 676) called such a deed valid "to the extent of" the signing co-owner's share. You get an undivided fractional interest, not the whole property.

The sub-registrar registered the deed, so surely all heirs must have signed? Not necessarily. In K. Gopi v. Sub-Registrar (2025 INSC 462) the Supreme Court held that a registering officer cannot verify or adjudicate the seller's title and must register a document if the procedure is complete. Registration proves the deed was executed and recorded, never that every co-owner signed.

The property was self-acquired by the deceased. Do the other heirs still need to sign? Yes, if the owner died without a will. On intestacy, self-acquired property devolves on all the Class I heirs together as tenants-in-common (Sections 8, 10 and 19 of the Hindu Succession Act). Each holds a fixed share, and all of them must sign to sell the whole.

Can I just buy the shares of the heirs who are willing to sign? You can, but understand what you are buying: an undivided fractional interest and the right to sue for partition, not a specific plot you can occupy or fully register. For a family dwelling house, the second paragraph of Section 44 may even bar you from joint possession until partition.

One of the heirs was a minor and a parent signed for them. Is that valid? Only if the court gave prior permission under Section 8 of the Hindu Minority and Guardianship Act. Without it, the sale of the minor's share is voidable, and the minor can move to set it aside up to about three years after turning 18.

A missing heir signed a plain "family settlement" letter later. Does that fix it? Usually not. Under Kale v. Deputy Director of Consolidation ((1976) 3 SCC 119), only a memorandum recording an already-completed, independent partition can be unregistered. A paper that itself divides or releases a share must be a registered deed to be effective.

Will an encumbrance certificate show that an heir is missing? No. An EC lists registered instruments and the people who signed them. It cannot reveal an heir who never appeared on any deed. Finding a missing heir requires reconstructing the family tree and checking it against the signatures across the whole title chain.
