Quick Summary

In law, a witness is someone who provides testimony to establish a fact. This testimony can be oral or documentary. Under Anglo-American law, almost anyone can be a witness, including parties to a lawsuit and experts, though their credibility may be questioned. Continental European law has stricter rules, often excluding parties and experts as witnesses.12

Witnesses may be protected by privileges that allow them to refuse to testify in certain situations, such as if their testimony could incriminate them or reveal confidential information. The oath is a traditional method to encourage truthful testimony, though some jurisdictions allow affirmations for those who object to oaths. Ultimately, judges and juries evaluate witness testimony freely.12
