You sound like a great guy there are 2 avenues to take. Initially, please realize that Michigan law has an automatic presumption that you are the father since you were married to her when the child was born. However, there is a relatively new legal procedure by which you have to prove that you are not the father to get out of the presumption so you do not have to pay child support. So First you can file for divorce now and based upon the child DNA test showing you are not the father jump through the hoops in the law so you do not have to pay child support. Or Second, wait a bit once she gets the results of the paternity test from the other guy and assuming she wins child support from him that judicial finding acts as a judicial determination that you are not the father and she cannot claim child support or anything else from you in the future on behalf of the child she is NOT eligible for child support from 2 different men for the same child.
