30-year-old letter admitted as evidence—court cites convenience

A letter sat in a drawer for 30 years. When it was brought to court, the judge said—it could be presumed genuine, without a single witness to prove who wrote it.

The question that hung over the case was simple. Could a document older than most of the lawyers in the room be admitted as evidence when no living person could swear to its handwriting? The Supreme Court's answer would change how old letters, deeds, and agreements are treated in Indian courts.

When the letter came out of the drawer

In Lakhi Baruah v. Padma Kanta Kalita, a civil dispute reached the Supreme Court. At its heart lay a document that had been sitting untouched for three decades. The party who wanted to rely on it produced it from what they said was proper custody—kept in the natural place where such a document would be stored. The other side objected. How could anyone prove, after 30 years, that the handwriting on that letter was genuine? The witnesses who might have seen it written were long gone. The ink had faded. The paper had yellowed. The person who signed it might have died years ago.

This was not a small objection. In Indian evidence law, a document is not automatically accepted as true just because someone files it in court. The party relying on it must ordinarily prove its execution—that the person who appears to have signed it actually did sign it, and that the document is what it claims to be. But after three decades, that ordinary burden becomes extraordinary.

Why proving old handwriting becomes nearly impossible

The Supreme Court recognised a practical reality that every trial lawyer knows. After 30 years, the person who wrote the document may be dead. The person who saw it being signed may be dead. Even if they are alive, their memory of a single signature from three decades ago is unlikely to be reliable. The Court observed that Section 90 of the Evidence Act, 1872—the provision that allows old documents to be presumed genuine without proof of handwriting—is founded on necessity and convenience. It acknowledged that "it is extremely difficult and sometimes not possible to lead evidence to prove handwriting, signature or execution of old documents after lapse of thirty years".

This is not a theoretical problem. In property disputes, family settlements, and commercial agreements, documents often surface decades after they were created. A partition deed from 1975. A will from 1980. A letter of understanding from 1992. If every such document required a live witness to prove its handwriting, most old documents would be worthless in court. The law would be asking litigants to do the impossible—to summon the dead, or to expect reliable testimony about events that happened before most lawyers were born.

The Court's reasoning was rooted in the texture of real litigation. Consider a family dispute over ancestral land. The only surviving evidence of a partition might be a deed signed by the grandfather in 1965. The grandfather is dead. The uncle who witnessed the signing is dead. The village scribe who drafted it is dead. Without Section 90, that deed would be inadmissible. The family would lose its land not because the deed was forged, but because the law demanded proof that time had erased.

What Section 90 actually does

Section 90 of the Evidence Act creates a special rule for documents that are at least 30 years old. When such a document is produced from what the court considers "proper custody", the court may presume that the document is genuine—that it was signed by the person who appears to have signed it, and that it was executed on the date it bears. The key phrase is "proper custody". This does not mean any custody. It means custody that is natural and appropriate for that kind of document. A family deed kept in a family trunk is proper custody. A business agreement kept in a company's file room is proper custody. A letter found in a stranger's pocket is not.

The Court explained that Section 90 was incorporated into the Evidence Act to "do away with the strict rule of proof of private documents". The strict rule would require the party to call the writer, or someone who saw the writer sign, or a handwriting expert. Section 90 removes that burden for old documents. It is a pragmatic concession to the reality that time is the enemy of proof.

But what does "proper custody" look like in a courtroom? It is not enough for a litigant to walk into court and say, "This document is old, so presume it is genuine." The court must be satisfied that the document was kept where it ought to have been kept. If a will is produced by the son of the deceased, and the will was found in the deceased's own steel almirah among other personal papers, that is proper custody. If a rent agreement from 1990 is produced by a stranger who says he found it in a trash bin, that is not proper custody. The court will look at the naturalness of the possession—whether the person producing the document is the person who would reasonably have had access to it.

How the presumption works in practice

The presumption under Section 90 is not automatic. The court has discretion. It may presume genuineness, but it is not forced to. The judge looks at the document, considers the custody from which it was produced, and decides whether the presumption should be raised. If the document appears suspicious—if it has erasures, if the ink looks too fresh for its claimed age, if the custody is unnatural—the court can refuse to raise the presumption. The burden then stays on the party relying on the document to prove its genuineness by other evidence.

But if the document is produced from proper custody and appears regular on its face, the court can raise the presumption. Once raised, the other side must then produce evidence to rebut it—to show that the document is forged or that it was not signed by the person it claims to be. The burden shifts, but it does not disappear. The opposing party can still attack the document by showing inconsistencies in its contents, by pointing to suspicious circumstances, or by producing their own evidence about its origin.

In practice, this means that a litigant relying on an old document must do two things. First, establish the age of the document—usually by showing the date it bears and satisfying the court that the document is indeed at least 30 years old. Second, establish proper custody—by leading evidence about how the document was preserved, where it was kept, and why that custody is natural. A bald statement in court that "this document is 30 years old" is not enough. The court must be satisfied on both counts.

Why the court called it a rule of necessity

The Supreme Court's reasoning in Lakhi Baruah was grounded in practicality. The law of evidence exists to help courts discover the truth. If the law made it impossible to prove old documents, the truth would remain hidden. Old frauds would go unpunished. Old rights would go unenforced. The Court firmly established the foundational rationale—practical necessity—for treating 30-year-old documents differently under the law of evidence. This is not a technical loophole. It is a recognition that time destroys evidence, and the law must adjust to that reality.

The judgment also clarified that the 30-year period is counted from the date the document bears, not from the date it was filed in court. A document dated 1 January 1990 becomes eligible for the presumption on 1 January 2020, even if it was filed in court only in 2023. The clock starts ticking from the moment the document was created, not from the moment it entered the litigation.

But the presumption is not a free pass. The Supreme Court itself noted that Section 90 was designed to "do away with the strict rule of proof of private documents"—not to do away with proof altogether. The document must still be produced from proper custody. The court must still exercise its discretion. The opposing party must still have an opportunity to rebut. The presumption is a tool of convenience, not a licence for forgery.

What this means for lawyers and litigants

For practitioners, the takeaway is clear. If you have a document that is 30 years old or older, you do not need to scramble to find a handwriting expert or a witness who saw it being signed. You need to show that the document comes from proper custody—that it was kept where it would naturally be kept. But the burden of showing proper custody is real. You must lead evidence about how the document was preserved, where it was found, and why the custody is natural.

For litigants, the lesson is equally important. If you are faced with an old document that your opponent is trying to admit, you must attack the custody. Ask: Who kept this document? Where was it stored? Why is this person producing it now? If the custody is unnatural or unexplained, the court may refuse to raise the presumption—and your opponent will be left without evidence.

THE PLAY: When relying on a 30-year-old document, file an affidavit explaining the chain of custody—who kept it, where it was stored, and how it came to court—before asking the court to raise the Section 90 presumption.

When the letter spoke for itself

The letter in Lakhi Baruah had sat in a drawer for 30 years. The person who wrote it was gone. The person who received it was gone. But the document itself, produced from proper custody, was allowed to speak. The court did not need a living witness to tell it what the paper already said. The law had bent—not to break the rules of evidence, but to acknowledge that after three decades, the paper itself is often the only witness left.
