Louisiana Alimony Law Overview

Louisiana distinguishes between interim periodic support during proceedings and final periodic support after divorce. Final support is capped at one-third of the paying spouse's net income. Adultery by the requesting spouse completely eliminates their right to final support.

Formula & Calculation Approach

Interim support is based on the needs of the requesting spouse and the other's ability to pay. Final support is capped at 1/3 of net income. Courts consider the needs of the spouse and financial obligations.

Duration Rules in Louisiana

Final periodic support is paid until the recipient is no longer in need. Support terminates on remarriage.
