Section 3-405
If evidence concerning execution of the will is necessary, the affidavit or testimony of 1 of any attesting witnesses to the instrument is sufficient. If the affidavit or testimony of an attesting witness is not available, execution of the will may be proved by other evidence or affidavit.
Comment
For various reasons, attorneys handling estates may want interested persons to be gathered for a hearing before the Court on the formal allowance of the will. The Court is not required to conduct a hearing, however.
If no hearing is required, uncontested formal probates can be completed on the strength of the pleadings. There is no good reason for summoning attestors when no interested person wants to force the production of evidence on a formal probate. Moreover, there seems to be no valid distinction between litigation to establish a will, and other civil litigation, in respect to whether the court may enter judgment on the pleadings.
Massachusetts comment
Orders may be entered in uncontested matters without hearing by the Court or Magistrate. See Section 1-401.
