condition precedent

n. 1) in a contract, an event which must take place before a party to a contract must perform or do their part. 2) in a deed to real property, an event which has to occur before the title (or other right) to the property will actually be in the name (vest) of the party receiving title. Examples: if the ship makes it to port, the buyer agrees to pay for the freight on the ship and unload it; when daughter Gracella marries she shall then have full title to the property.
