Short answer. Not necessarily. Where a private document is more than thirty years old, comes from the custody where a genuine document of that kind would naturally be kept, and shows no alterations or suspicious circumstances, no other evidence of its authenticity needs to be given — this is the ancient document rule.
What the law says
Where a private document is more than thirty years old, is produced from a custody in which it would naturally be found if genuine, and is unblemished by any alterations or circumstances of suspicion, no other evidence of its authenticity need be given.

Three conditions have to be met together
The exemption from ordinary authentication requires all three elements at once: the document must be more than thirty years old, it must be produced from a custody in which it would naturally be found if genuine, and it must be unblemished by any alterations or circumstances of suspicion. Missing any one of these takes the document outside the rule, and ordinary proof of authenticity is then required.
"Natural custody" is about where the document came from
A document's age alone is not enough. It also has to come from a custody in which it would naturally be found if genuine — for example, a deed found among a family's other old property papers, or an old will kept with a decedent's papers, rather than surfacing from an unexplained or suspicious source that raises questions about how it was obtained or where it has been. Where the document actually came from before it reached the courtroom is often the first thing an opposing party will probe.
Alterations or suspicious circumstances defeat the exemption
Even an old document from the right kind of custody loses the benefit of this rule if it is not unblemished by any alterations or circumstances of suspicion. Visible changes to the text, unexplained erasures, or anything else that casts doubt on the document's integrity means the party relying on it has to prove authenticity the ordinary way rather than through this shortcut, typically through witnesses who can speak to its execution or genuineness directly.
Why this rule exists
Requiring live testimony to authenticate every genuinely old document would often be impossible — the people who could testify to its execution may be long dead by the time it becomes relevant in litigation. The ancient document rule lets a document's age, provenance, and apparent integrity substitute for that missing direct testimony, but only where all three conditions genuinely hold, and a party relying on it should be ready to show each one.
