Commissaria Lex

A principle of the Roman law relative to the forfeiture of contracts. It was not unusual to restrict a sale upon credit, by a clause in the agreement that if the buyer should fail to make erty was the buyer's, and at his risk. A debtor and his pledgee might also agree that, if the debtor did not pay at the day fixed, the pledge should become the absolute property of the creditor.

2 Kent, Comm. 583.

This was abolished by law of Constantine.

Code, 8. 36. 3.
