Does remarriage automatically cause permanent alimony to terminate?

Actually, there is one case where permanent alimony would continue after the traditional cessation point of remarriage: if you and your ex-spouse should negotiate that in the settlement agreement. You can always agree to continue permanent alimony after remarriage. This is not common, but has and will continue to be done under certain unique circumstances.

For example: your ex-wife may be willing to accept a smaller monthly payment if she knows that it would continue should she remarry. That way you would have a smaller monthly payment, albeit for a longer period of time.
