Sep Agreement in place and dating/adultry concerns

We have a signed sep agreement in place since last summer that covers all property, financials, child custody/support- EVERYTHING. Mostly her idea, since she knew I was in contact with previous girlfriend. My question is can anything in SA be altered or “thrown out” because of adultry after SA created and signed? She is telling me that she can go back and ask for changes in property/alimony… because of new information concerning possible adultry AFTER SA was signed. Is this true?


No, the agreement cannot be thrown out on the basis of undiscovered adultery.
