There are several things post divorce that can be modified - these include parenting time with a child or custody of the child, child support, and spousal support. A clause in a divorce decree that says spousal support will terminate upon death of the paying spouse or remarriage of the recipient spouse is pretty common. The termination upon death of the paying spouse is actually required to meet with tax law requirements and is usually offset with the requirement that the paying spouse maintain life insurance that gets paid to the recipient spouse if the paying spouse dies. The clause about remarriage is intended to recognize that the recipient spouse now has a new spouse who replaces the spouse from the former marriage and who now can be a source of spousal support for the recipient spouse.
What will happen in your particular situation is hard to determine via the small amount of information we see here on face book. To get legal advice for this type of problem you need to take your divorce decree and go and talk to a lawyer. Not only do they have to read your particular decree but they need to discuss with you the circumstances of your divorce. It may be that the termination of spousal support is not absolute and will depend on the examination of other factors.
Spousal support is ordered for different reasons. There is the traditional general maintenance type of support which is for the spouse that just didn't have much earning potential and needs economic assistance. There is also the type of spousal support known as transitional, which is just a temporary fix to help the low income spouse get job training and reenter the workforce. There is also compensatory spousal support which is like paying back a student loan and is meant to compensate a spouse that sacrificed by working and supporting the other spouse while they went to school and built a high paying career. So of these three types of support, the first type, general maintenance, is the type that would typically be replaced by the new income of a new spouse and thus would properly be terminated. The latter two types of support, transitional and compensatory shouldn't be terminated because they are meant to be paid for different reasons that are not removed by remarriage. There can be spousal support that is part of an agreement by spouses on the overall division of assets and debts from the marriage. Spousal support that is meant to balance a division of assets or debts should not be terminated upon remarriage. Finally in some marriages the spouses agree that any spousal support they have agreed to can't be terminated and the court will generally enforce this type of agreement despite a later change of circumstances like remarriage.
Understand that generally speaking either party can generally go back to court and seek a modification of the spousal support award after the divorce, even when the decree is silent. The underlying idea behind spousal support is normally to help the lower income spouse survive while they try to become financially independent, which can occur by them improving their income from employment or by remarriage. So even where a spousal support decree doesn't state that it terminates upon remarriage, the court can still be asked to terminate the support when the financial conditions of the recipient spouse change. (Conversely, the recipient spouse can seek an increase in spousal support or the duration of the support when the conditions as well.) Again predicting the possible outcome of revisiting the issue in court depends on analyzing the wording of the decree, the circumstances of the divorce when the decree was issued, the purpose for which the support was ordered in the first place, and the current circumstances of the both former spouses. http://www.portlandlegalservices.com
