I would like to discuss the repeal or amendment of my next treaty, on the basis that there was no quid pro quo, it was signed under duress and by misrepresentation. Please contact me as soon as possible. Thank you very much! uniformlaws.org/shared/docs/premarital%20agreement/upaa_final_83.pdf fault of one or both parties with regard to marriage does not necessarily result in the invalidity of a postal or marriage contract. For example, adultery is usually not enough to nullify an agreement. Traditionally, the behavior must be rude enough that it is beyond the idea of the parties being bound by its conditions.
