Yes, but it might take a court order. Single fathers have no rights to see the child without an order, plus if a child support order is not in place, you better get it done. see links
Yes.
It's likely that the father will still owe support until/unless the child is adopted. see links
No he does not because he is not the child's parent anymore.
yes see link
Child support is calculated based on income of the father (or mother in such a case). If the father is unemployed his child support will still be calculated based on whatever minimum wage is in your state. The only time this does not apply is when the father is on disability. Welfare shouldn't matter.
No, but you can't anyway. see link
It is just like if the father did not see the child. He would have to pay child support. Visitation and custody are 2 separate things in the court system. Whether a parent sees a child or not, support is usually still issued. If the judge signed a support order and it is not payed, that parent can go to jail for unpayed child support.
No. Visitation and child support are 2 separate issues and the child (although now adult) does not have to see the parent. The parent is always obligated to support the child anyway. Child support usually stops from age 18 though but in some states it can be prolonged when the child is in college.
i dont think so cause youre not abandoning him if u support him but its not nice to not want to see youre child
You will still have to pay back if any owed. After you sign you won't have to pay anymore because all your legal rights to the child will be terminiated. If Mom agrees to let you voluntarily terminate your parental rights, then, no, you won't have to pay child support going forward (but will still have to pay any arrearage unless Mom agrees to forgive it). But DO NOT do this if it not what you want to do. If you want to be a father, fight for it. Get court ordered visitation, then if Mom refuses to allow you to see your child, she can be held in contempt of court.
If an order is still in place, yes, even in Michigan. see links below
