Section 3-105
Persons interested in decedents' estates may petition the magistrate for determination in the informal proceedings provided in this article, and may petition the court for orders in formal proceedings within the court's jurisdiction including but not limited to those described in this article.
Comment
This and other sections of Article III contemplate a non-judicial or quasi-judicial officer who will act on informal petition and a judge who will hear and decide formal petitions. See Section 1-307 which permits the judge to perform or delegate the functions of the Magistrate.
Massachusetts comment
See G.L. c. 215, §§ 3 and 6 for jurisdiction of the Court.
