Definition of Mitigation of Damages
After a tort the theory of mitigation of damages requires the victim to take reasonable steps to minimize their loss. For example, the victim should get proper medical care for their injuries. If a plaintiff fails to get proper medical care or remedy the injury the court could decide they will not be fully compensated for their loss.
Mitigating of damages can also occur in other types of cases such as breach of contract. For instance, if a renter breaches a contract and leaves their rental home prior to the expiration of the lease the landlord is required to attempt to mitigate their damages and seek another renter. If they fail to perform this duty the court may decide not to compensate them for the full extent of the lease.
