A witness sees his signature on a document but has no recollection of the transaction whatsoever. May he testify in court about it?
A witness testifies about the transaction, not just his signature. His signature helps trigger memory — but if memory cannot be restored, he is forbidden to testify. Testifying without actual knowledge would be equivalent to testifying falsely.
Question 2
The plaintiff himself reminds the witness of a transaction, and the witness then remembers. May he testify?
If the plaintiff reminds him, it appears to the beit din that the witness is testifying based on what the plaintiff told him — not from his own knowledge. This creates an unacceptable appearance of false testimony.
Question 3
A witness forgot a transaction for ten years. Seeing his signature reminds him fully. May he testify?
In financial cases, a leniency allows a witness whose memory was restored by seeing his own signature to testify — even after many years. Genuine memory, however dormant, is valid.
Question 4
Witnesses say their signatures are genuine but they have no memory of the transaction. Their signatures can be verified by comparison with other documents. Is the document valid?
When signatures can be independently verified, the court disregards the witnesses' claim of forgetfulness — suspecting it is an attempt to void the document. The document stands on the independently verified signatures.
Question 5
A witness finds in his own records a note in his handwriting: 'So-and-so asked me to witness that he owes So-and-so 100 dinars.' He does not remember the event. May he testify?
Even one's own personal notes do not substitute for actual memory. Without genuine recollection, the witness cannot testify — the note is comparable to hearsay from another person.
