Thank you for contacting Just Answer for assistance. Sorry for the delay; I had a lengthy answer that disappeared into cyberspace. So, here we go again...
1. Interim spousal support in LA terminates upon the grant of the final Judgment of Divorce unless there is a pending claim of permanent support. In that case, interim support continues until the first occurrence of 1) the denial or granting by the court of the permanent support claim or 2) the expiration of 180 days from the granting of the divorce judgment unless the court continues it for good cause shown. Here's the relevant section of the Louisiana Civil Code:
Art. 113. Interim spousal support allowance pending final spousal support award
Upon motion of a party or when a demand for final spousal support is pending, the court may award a party an interim spousal support allowance based on the needs of that party, the ability of the other party to pay, and the standard of living of the parties during the marriage, which award of interim spousal support allowance shall terminate upon the rendition of a judgment of divorce. If a claim for final spousal support is pending at the time of the rendition of the judgment of divorce, the interim spousal support award shall thereafter terminate upon rendition of a judgment awarding or denying final spousal support or one hundred eighty days from the rendition of judgment of divorce, whichever occurs first. The obligation to pay interim spousal support may extend beyond one hundred eighty days from the rendition of judgment of divorce, but only for good cause shown.
Acts 1997, No. 1078, §1, eff. Jan. 1, 1998; Acts 2001, No. 738, §1; Acts 2003, No. 1092, §1.
2. If you stop paying without the order of the court, you will be subject to contempt sanctions including a judgment for arrears.
3. DO NOT quit your job to avoid support! No good will come from either voluntary unemployment or under-employement.
4. It's always better to settle your case vs. going to trial. People who settle have more control over their destiny. But if one or both parties are stubborn, irrational or insistent upon a legal claim that is invalid, you're probably better off going to trial. Settlement vs. trial is a strategy decision to be made with your lawyer, taking into account all factors, including a cost-benefit analysis to you.
5. To protect yourself financially (I assume you mean with respect to the alimony claim), maintain the status quo. Don't take on significant fixed expenses in an effort to claim your available income is suddently less.
