Section 9

The Probate Officer may require the attendance of any party in person, or of any person whom he may think fit to examine or cause to be examined, in any action or other proceeding in respect of matters or causes tes-tamentary, and may examine or cause to be examined upon oath parties and witnesses by word of mouth, and may, either before or after or with or without such examination, cause them or any of them to be examined upon interroga-tories or receive their, or any of their, affidavits.

The Probate Officer may by writ require the attendance of any such party or witness, and order to be produced before himself or otherwise any deeds, evidences, or writings, in the same form, as nearly as may be, as that in which a writ of subpoena ad testificandum or of subpoena duces tecum is now issued by the High Court in its original jurisdiction.
