What should my brother and sister-in-law do if they want a divorce?

Let's see if we can settle this peacefully. It is not easy to get together in life, and it is inseparable. Try to persuade my sister-in-law more and see if this can be solved. This is the best policy. If the best policy can't be solved, use the worst policy to solve it. It's wrong to get paid under false pretenses. You should be able to sue her for this. Don't be afraid to keep your secret. Just talk to your bosom friend. Let the people know who your sister-in-law is. Find a suitable time to talk about it. For example, when you tell your intimate friends about your sister-in-law, you should bring a sentence or two to let them know. You are a good man, making people think that your uncle is innocent.
