Proof in Solemn Form Law and Legal Definition
Proof in Solemn Form is a pronouncement by a court of law that a will is formally approved and not subject to later contest barring fraud or the discovery of a later will. Proof in solemn form involves complex procedures and forms and may require opening a file in a higher court. It usually delays the administration of an estate and costs more if legal fees are required. There are state specific rules regarding proof in solemn form.
For example, in Missouri the proof in solemn form is required only when a contest arises, and then the case is transferred to the Circuit Court in the mode provided by law. [State ex rel. Callahan v. Hess, 348 Mo. 388, 396 (Mo. 1941)]
