For a Maryland Protective Order, you would complete and file a Petition for Protective Order. 

You file the petition to obtain a Temporary Protective Order with the clerk in any District Court or Circuit Court when the court is open, 8:30 a.m. to 4:30 p.m.

However, if the court is closed, you can file the petition to obtain an Interim Protective Order with the Commissioner’s Office of the District Court, which is open at all other times (24 hours) every day including weekends.
