Rehabilitative alimony helps the receiving spouse return to school or learn skills that will increase their ability to find employment and become self-sufficient. Typically awarded for a specific time period.
Restitutional Alimony
Restitutional alimony reimburses the receiving spouse for contributions made toward the other spouse's education or professional training received during the marriage.
