Md. Code, Courts and Judicial Proceedings § 12–501

(a) A party may appeal to the Appellate Court of Maryland from a final judgment of an orphans’ court.

(b) However, if the final judgment was given or made in a summary proceeding, and on the testimony of witnesses, an appeal is not allowed under this section unless the party desiring to appeal immediately gives notice of the party’s intention to appeal and requests that the testimony be reduced to writing.

(c) In such case the testimony shall be reduced to writing at the cost of the party requesting it.
