@heartkat “I’m pretty sure that the three day buyers remorse clause is across all 50 states.”
Yes, and specific states can be more generous. For example, someone might have 5 or 10 “buyer’s remorse” days in certain states. But, as I emphasize again, the “cooling off” rules apply only to a limited range of specific transactions. Someone can’t simply sign any and every contract and expect to back out.
As @elbanditoroso points out, marriage contracts are rather difficult to end! And, annulment is very different from breaking a contract. An annulled marriage means that the contract hadn’t been valid and, thus, that the marriage never existed.
