In Law, Apportionment is the method used to determine a claimant’s payment for permanent workers’ compensation injury awards. For instance, if you have been previously injured your employer is allowed to reduce benefits for your current injury through the process of “apportionment.”

Factors such as causation, risk factors, age, prior industrial accidents, prior awards and prior disabilities are all factored into the apportionment decision making process. Specific requirements must be met to apportion a certain percentage of your past injury’s disability from the amount of disability that you have with your current injury. Generally, claimants are entitled to their full workers compensation benefits. If you need help getting workers compensation talk to a work comp lawyer.
