Md. Code, Commercial Law § 17-322

(a) At reasonable times and on reasonable notice, the Administrator may examine the records of any person if there is reason to believe that the person has failed to report property that should have been reported under this title. The Administrator may not examine the records of any person regarding abandoned property after 5 years from the date the person filed the report with the Administrator covering the period of time during which the property allegedly became abandoned, unless the Administrator finds that the person acted fraudulently or with gross negligence with respect to the report.

(b) If any person refuses to permit the examination of records, the Administrator may issue a subpoena to compel the person to testify and produce records. The subpoena shall be served by the sheriff of the county where the person resides or may be found. The person shall be entitled to the same per diem and mileage as witnesses appearing in a circuit court of the State, which shall be paid by the State.

(c) If any person refuses to obey any subpoena so issued or refuses to testify or produce records, the Administrator may present a petition to the circuit court of the county where the person is served with the subpoena or where the person resides. The court then shall issue an order to require the person to obey the subpoena or to show cause for failure to obey it. Unless the person shows sufficient cause for failing to obey the subpoena, the court immediately shall direct the person to obey and, on refusal to comply, adjudge the person to be in contempt of court and punished as the court may direct.
