If Wisconsin had jurisdiction in a case with the same facts as we are reading about in the media regarding Tiger Woods, his conduct would have little impact because Wisconsin is a no fault divorce state.  His behavior could be a factor relative to placement of his children, but you would have to show that his marital misconduct impacted the best interests of the children – which could be a difficult burden to meet.  If Tiger Woods and his wife had a prenuptial agreement, the issue of marital misconduct could be addressed in that document which would be a factor in property division.
