Legal Definitions - resolutory condition

A resolutory condition is an uncertain event that, upon its occurrence, terminates an already enforceable obligation and restores the parties to their original positions. For example, if a person promises to pay another person $500 for repairing their car, the failure of the repair (an implied or constructive condition) relieves the person of the promise to pay.

Another example of a resolutory condition is a lease agreement that terminates upon the sale of the property. Once the property is sold, the lease agreement is terminated, and the parties are restored to their original positions.

Overall, a resolutory condition is a condition that, when fulfilled, ends an already enforceable obligation and restores the parties to their original positions.
