You need to prove two things:

1.) Disposition
2.) Opportunity

Evidence must include the testimony of a corroborating third party. It is not sufficient for the spouse committing adultery to simply admit the adultery.

In my case:
1.) Disposition (My wife abandoned her car in a parking lot and jumped in car with OM, obviously wanting to hide what she was doing)
2.) Opportunity (My wife spent the entire night at OM's house)

Corroborating third party: Private Investigator

Supporting Evidence: Video/Pictures/Testimony from me

Admissions aren't enough because they may show collusion where two parties are getting a fault divorce by colluding with each other to avoid a state waiting period.

You do not have to show actual intercourse.
