My fiance' has a son that will be 5 in May. He and the mother spilt up when the son was only 1 1/2 years old. Of course, she got a child support order on him, which essentially takes half of his income. The mother has denied him visitation (and has moved and we have no idea where she is) and he has not seen his son in over 3 years. The mother is also remarried, so has a stable household and a father figure that would be more than capable of financially supporting the son. We are now trying to start a family of our own, and raise my son, which is hard to do on our limited income. Not to mention the fact that my fiance' is supporting a child that he never gets to see, and who would have no idea who he was were he to run into him on the street. We know she is an unfit mother, but there is no way of proving it. We live in Missouri, which is tailored to the mother in these cases. Do we have a chance of getting custody? Do we have a chance of getting a judge to terminate parental rights and terminate child support?
