When I got a girl pregnant, was young and never got a test and signed the recognition of parantage form in Minnesota, we got married about a year later and that did not last, never thought the boy looked liked me but always wondered and never got a test, fast forward a few years he is now 8, I finally got a good job I am married now and have 2 kids with my wife, I take my 8 year old 2 days a week, I get a thing from child support saying I have to pay 1400 a month! I have a family at home I have to take care of too after taxes and everything that is almost half my take home pay, so I got a dna test done and it turns out he is not my kid, I live in wisconsin and my sons mom lives in wisconsin what are my options?
