I have full coustody of my 3 kids I gave my x wife house in divorce she owe me back child support and don't pay can I get home back
If she got the house in a divorce settlement then it's hers , you can get back child support from her.
You can only sue for your back child support; there is no way the court will give you the house back. The house is her entitlement according to the court, so it belongs to her now, not you. Talk to an attorney for professional legal advice.
call an attorney, definitely. you may be able to sue in civil court for the house, but it would be pricey and may not work.
you cnt go back home but you can take her to court for child support
