Dependent on the laws in your state, you may be fully reimbursed for your deductible if:

•    The other party was 100% at fault
•    The other party paid the damages claimed in full 
•    There were no collection expenses (i.e. collection agency) to recover the money.

Often times though, it is not that simple.  Based on the different factors that come into play, the calculation of the reimbursement amount can become quite complicated. The reimbursement of your deductible depends on several factors, including the amount recovered, the amount claimed (based on the amount the various parties were at fault), and state laws.

Generally, you would receive reimbursement of your deductible equal to your proportion of the total amount claimed to the total amount recovered, net of expenses. However, precisely how the reimbursement amount is determined varies by state.

The following examples outline general rules that apply in many states—please discuss the specifics of your case with your subrogation claim representative.
