A notary's signature: automatic proof or just a stamp?

A notary stamped a Power of Attorney. The court said: that seal alone makes it valid—unless the notary skipped the one step that matters.

Two property disputes. Two different courts. One question: does a notary's stamp automatically prove that the person who signed a Power of Attorney was who they claimed to be?

The answer depends entirely on whether the notary actually did their job.

When the seal became the only proof

In Jugraj Singh v. Jaswant Singh, the dispute reached the Apex Court over a Power of Attorney (POA) — a document that gives one person authority to act for another. A Notary Public, a government-appointed officer who verifies signatures and identities, had authenticated the POA. The courtroom was still, the only sound the rustle of paper as the bench examined the document. On the POA, the notary's seal sat crisp and dark, its embossed edges pressing into the fibre of the page.

One side argued the document was not genuine. The other side pointed to the notary's seal and signature and said: that's enough. The law says so.

The Supreme Court agreed — but with a crucial assumption baked into its reasoning.

The presumption that saved the document

The Court looked at Section 114 of the Indian Evidence Act, which lets courts presume that "official acts" were done properly. A notary's authentication is an official act under Section 8 of the Notaries Act. So the Court was "satisfied that he (the notary) must have satisfied himself in the discharge of his duties that the person who was executing it was the proper person."

That single sentence became the foundation of the judgment. The Court then applied Section 85 of the Indian Evidence Act, which says courts "shall presume" that a POA executed before and authenticated by a Notary Public was properly executed and authenticated. The word "shall" is mandatory. The court has no choice. The bench's voice was firm as it read out the finding — the presumption was not optional, it was commanded by statute.

The document was upheld. The seal, the Court said, carries strong initial statutory weight.

But what if the notary didn't check?

That question landed before the Bombay High Court in Prataprai Trumbaklal Mehta v. Jayant Nemchand Shah. The facts were different — a notary certifying a copy of a document as a "true copy" — but the principle was the same: does the notary's seal automatically prove the document is genuine?

The Bombay High Court said: not if the notary skipped the one step that matters. The courtroom fell quiet as the judges examined the notary's register — or rather, the absence of any entry in it. The page where the notary should have recorded the transaction was blank, save for the faint ghost of an erased pencil mark.

The Court examined what a notary is actually supposed to do. The law takes judicial notice of a notary's seal. An initial presumption may be made about the genuineness of the notarized document. But that presumption exists only because the notary is expected to be a responsible member of the legal profession who takes due care regarding the identity of the person appearing before them.

Section 85 of the Evidence Act creates a rebuttable presumption (a presumption that can be challenged and overturned with contrary evidence) about the genuineness of the POA and the identity of the person who signed it. But the Bombay High Court made clear: this presumption is not automatic. It is earned.

What the notary must actually do

The Bombay High Court laid out the minimum steps. If the notary marks a document as a true copy "without taking due care and even making any entry in the notary register and without taking signature of an advocate identifying the executant or without taking other reasonable precaution," the Court said, "it cannot be said that the notary is discharging his duty in accordance with law as expected of him." The register entry — a simple line in a bound book with a date, a name, and a description — was the first and most basic safeguard. Without it, the notary's work was incomplete.

More specifically: if the person appearing before the notary is unknown to the notary personally, the notary must "get the party identified by an Advocate known to him and take signature of both of them in token thereof." The advocate's signature line, sitting below the executant's name in the register, was the second safeguard — a second pair of eyes confirming the identity.

This is not a suggestion. It is the standard of care that the law expects.

When the foundation crumbles

The Bombay High Court's reasoning is devastatingly simple. The initial presumption of genuineness arises only because the notary is expected to take due care to satisfy themselves about the identity of the party. If the notary fails in this duty — no entry in the notary register, no identifying advocate signs, no reasonable precaution — then the foundation for the presumption of regularity is weakened or destroyed entirely.

The seal becomes just a stamp. The signature becomes just ink. The document becomes vulnerable to challenge.

In the Prataprai case, the notary's register was produced in court. The pages were turned slowly by the court clerk, each leaf inspected for the missing entry. The silence in the room was heavy as the absence became clear — the notary had not recorded a single detail of the transaction. The presumption that had protected the document in Jugraj Singh was gone.

The two judgments sit side by side, not in conflict but in balance. The Supreme Court in Jugraj Singh established the strong initial presumption. The Bombay High Court in Prataprai Trumbaklal Mehta defined the condition on which that presumption rests: actual, demonstrable due diligence by the notary.

In Jugraj Singh, the notary had satisfied himself about the executant's identity — the Court accepted that the notary "must have satisfied himself in the discharge of his duties that the person who was executing it was the proper person." The seal had meaning because the notary had done the work behind it. In Prataprai, the notary had done nothing — no register entry, no advocate identification, no reasonable precaution — and the seal was left standing alone, unsupported by any evidence of due diligence.

The difference between the two outcomes is the difference between a notary who acts and a notary who merely stamps.

What this means for anyone signing a Power of Attorney

For practitioners, the lesson is practical. A notarized POA carries a powerful statutory presumption. But that presumption is rebuttable — and the easiest way to rebut it is to show that the notary did not follow the required procedure.

If you are relying on a notarized POA, ensure the notary has made a proper entry in the notary register. The register should show the date, the name of the executant, a description of the document, and the notary's own signature. If the notary did not know the executant personally, ensure an advocate known to the notary identified the executant and signed the register. The advocate's signature is a second layer of verification — a safeguard against impersonation and fraud.

If you are challenging a notarized POA, ask for the notary register. Ask whether the notary knew the executant. Ask whether an identifying advocate signed. The absence of these steps may be enough to destroy the presumption. In court, the register is the first piece of evidence the opposing side will demand — and if it is missing or incomplete, the foundation of the presumption crumbles.

The Jugraj Singh case established the rule: the seal creates a presumption. The Prataprai case established the exception: the presumption is only as strong as the notary's actual diligence. Together, they form a complete picture of the law — one that rewards careful notaries and punishes careless ones.

THE PLAY: Before relying on a notarized Power of Attorney, verify that the notary made a register entry and — if the executant was unknown to the notary — obtained an identifying advocate's signature. Without that, the statutory presumption is hollow.

The seal is only as strong as the notary who stamped it. And the notary is only as strong as the register entry they left behind.
