Massachusetts General Laws Part III. Courts, Judicial Officers and Proceedings in Civil Cases (Ch. 211-262) Ch. 215, § 2

Probate courts shall be courts of superior and general jurisdiction with reference to all cases and matters in which they have jurisdiction, and no order, judgment, decree, sentence, warrant, writ or process made, issued or pronounced by them need set out any adjudication or circumstances with greater particularity than would be required in other courts of superior and general jurisdiction, and the like presumption shall be made in favor of proceedings of the probate courts as would be made in favor of proceedings of other courts of superior and general jurisdiction.
