My question involves child support in the State of: Wisconsin
So my wife did everything right she send a letter to her ex husband telling him that she was moving to Hawaii with their two daughters. He hasn't seen his kids for 4 years, hasn't called, hasn't sent a letter, hasn't contacted for birthdays nothing. My wife has lived in the same house for 8 years, had the same phone number everything but no contact nothing. His child support has been spotty some months here and other months not but he has been getting more consistent.
So she sent him a letter saying that she was moving and 60 days later she moved to Hawaii. He contacted her saying that if she didn't waive child support then he was going to tie her up in court so she couldn't leave. He text her saying that he didn't care if she left but he wanted her to waive support from $500 to $50.
So she moved to Hawaii and now he is saying he wants to take her to court to prevent her from leaving. He isn't very smart the paperwork had her movement date but he apparently doesn't know that she was leaving on the day that she said she was.
The children are 15 and 17. Does he have any legal ground to stand on? Can he make her move her and the kids back to Wisconsin if he hasn't seen them in 4 years completely on the grounds that he doesn't want to have to pay support anymore?
I am not worried we did everything legally the way we were supposed to do but my wife is stressed because she is going to school out here and if the worst happened then she would be out and we would be in a bad financial situation.
