Can a spouse sue another person for having an extramarital affair that causes them to get a divorce?
You can sue the interloper for what’s called “tortious interference.” It’s been done successfully recently. (Recently for me is anything in the last ten years.) Basically, the idea is this: Persons A and B have a contract. Person C comes along and impels A to violate or break his contract with B. B sues C for tortious interference.
