Spousal Support Reduction

In Pennsylvania, if a soon-to-be-ex-wife has someone living with her (not a boyfriend) and that person is contributing financially to help with household expenses (not necessarily paying rent), can the soon-to-be-ex husband get a reduction in the amount of spousal support he has to pay her during the separation?

What if the person is living with the wife, not contributing financially to household expenses, but the wife included the extra need for income (in her expense report) based on the fact this person is living with her (need I mention she did not tell the court anyone was living with her). Is there anything the soon-to-be-ex husband can do to get the court to decrease the support? If he got proof that someone was living with her, would that be something the court could consider in decreasing support?

My apologies if this is too confusing but any input would be helpful. The court has taken half of my salary and given it to my ex (who is gainfully employed) during the separation. At the end of the year she will be getting more in "salary" than I will because of my support. I need to do something to stop this travesty. Thanks much!

You should consult with an attorney regarding the possibility of modifying the order under "change in circumstances" or perhaps pursuant to state civil rules which set forth how orders/judgements may be modified when there is new evidence, fraud, neglect, or otherwise. This would require a Motion to Modify Maintenance/Alimony to be placed before the Court of proper jurisdiction.
