Number of witnesses

No fixed minimum number of witnesses is needed to prove any fact. A single credible witness may be enough, while many witnesses who are unreliable do not help. It is for the court to judge credibility and decide whether the evidence proves the fact.

Anjali lends Rohan money and later says he promised to repay. No one else saw the promise; only Anjali will give evidence. Under this rule a single credible witness can suffice to prove the promise, and the court will decide how much weight to give her testimony.
