a type of litigation challenging the admission of a Will to probate

a unique hybrid form of litigation, fundamentally different from a typical civil trial and fraught with procedural peculiarities

Litigation to overturn a decedent's will for lack of testamentary capacity, undue influence or lack or proper execution.

When you challenge the validity of a Will in probate court. You can challenge a Will because: it was not executed properly; it was cancelled or revoked; the testator was not capable of writing it. (See Testamentary Capacity); someone put inappropriate pressure on the person who made it. (See Undue Influence); there was fraud; or there was a mistake.

A will contest, in the law of property, is a formal objection raised against the validity of a will, based on the contention that the will does not reflect the actual intent of the testator (the party who made the will). Will contests generally focus on the assertion that the testator lacked capacity, was operating under an insane delusion, or was subject to undue influence. A will may be challenged in its entirety, or only in part.
