A joke about finding out that his son doesn't look like him.

Sympathize with what happened to you. Fortunately, you are smart enough to find the root of the problem.

Your situation depends on the specific situation.

The first kind:

You negotiate with her, you produce your evidence, she must have nothing to say.

If she doesn't want to make a mountain out of a molehill, and she doesn't want you to know who her real father is. It is quite possible that she must agree to leave her clean home.

The second type:

Your agreement failed, and you chose to sue for divorce.

The judge will also decide to divorce you according to your situation.

In the division of property, because she is the wrong party, you can get more or all of the property.

But it depends on the judge's judgment on your marriage and your pain. The more serious the injury, the more property you get.
