Legal Definitions - reduction improbation

Definition: Reduction improbation is a legal action in Scots law that allows a person to challenge the authenticity of a document. It is also known as proper improbation.

Example: Let's say John has a will that leaves all his property to his son, but his daughter believes the will is a forgery. She can bring a reduction improbation action to court to prove that the will is false or forged. The court will then determine the validity of the will and either nullify it or uphold it.

Explanation: This example illustrates how reduction improbation works in practice. The daughter is able to challenge the authenticity of the will and bring it to court. The court will then decide whether the will is valid or not, based on the evidence presented. If the will is found to be false or forged, it will be nullified and the daughter may be entitled to a share of the property.
