Promissory Condition Law and Legal Definition
An unlawful condition is a condition which cannot be fulfilled without violating the law. An unlawful condition can be a term, provision, or clause in a contract. This term condition is generally used to describe any fact, after the formation of a contract. An unlawful condition operates to make the duty of a promisor immediately active and compelling. This is usually attached to the conveyance of property providing that if a particular event does or does not take place, the estate will be created, enlarged, defeated, or transferred.
