Credible Witness Law and Legal Definition

Credible witness is a person competent to give evidence, whose testimony can be believed and relied upon. A credible witness’s testimony will be trust worthy on the basis of his/her knowledge, training, experience and morale. The credibility of a witness is measured by the facts whether s/he is competent to know the testifying fact thoroughly, whether the witness actually witnessed the testifying fact and whether the witness honestly relates the fact fully, without any intention to deceive, or suppress the truth. In Delaware, Illinois, Maine, Maryland, Rhode Island, Vermont, and Virginia, wills need to be attested by credible witnesses to gain validity.
