Allocatur (from med. Lat. allocatur, "it is allowed"), in law, refers to the allowance of a writ or other pleading. It may also designate a certificate given by a taxing master, at the termination of an action, for the allowance of costs.
In Pennsylvania courts, the term is still commonly used to denote permission for an appeal to the Pennsylvania Supreme Court, even though the procedure for obtaining discretionary review in the court is now called a petition for allowance of appeal. See Pennsylvania Rule of Appellate Procedure 1112. In most other American courts, the term certiorari is used.
