Unus Nullus Rule: The Importance of Witness Testimony in Law

Definition & Meaning

The unus nullus rule is a legal principle stating that the testimony of one witness is equivalent to no testimony at all. In civil cases, courts typically do not give weight to the evidence provided by a single witness. For a claim or transaction to be proven, at least two witnesses are generally required. This is especially important in situations such as proving the validity of a will.

Real-world examples

Here are a couple of examples of abatement:

For instance, if someone wishes to contest a will, they would need at least two witnesses to provide testimony regarding the circumstances of its creation. (Hypothetical example.)

In a property dispute, if one party claims ownership based solely on their testimony, the court may dismiss their claim unless corroborated by another witness.
