The fact that the 18-year-old legally changed their name is irrelevant. Legal Dad (which would be biological Dad, not step-dad) is still responsible for child support for as long as the court has ordered.
Yes. You need to contact an attorney immediately. Your husband needs to support you while you are pregnant and will have to pay child support for the child until at least age eighteen.
husbands income does not count and is irrelevant
it stops
That depends on the state.
no
In a word, no.
A child has to be eighteen before the child support ends for a child. You then cant apply for child support than or you can get anymore for that child once you are eighteen you are done.
no
You be a good wife and support him. What else can you do?
No.No.No.No.
You need to visit the court, notify it that the child has reached eighteen years of age, and inquire about ending the child support order.
No, they are an adult.
