File for support as if the parent were not incarcerated. If the parent owns property such as a bank account or real estate it can be levied or have a lien placed against it. The child support amount granted will accrue while the parent is in custody and he or she will be held responsible for payment of arrearages when released.
Contact the MO child support agency for your county.
Yes (but not SSI).
Child support stops when the child turns 18 or earlier if a courts rules as such. Child support may be for longer if the child is in college.
Before or after a change of custody?
Indiana has 10 days to extradite. If it is for child support they will pick him or her up and extradite also.
you don't.
absolutely
None, SSI cannot be attached
If she is a minor yes. Pregnancy does not emancipate her and neither is she emancipated after the child is born.
There are no applicable laws in any state that says the person receiving the child support must be actually spending the money on the child, so no. However, it could be addressed as an issue of abandonment of the child if the mother is in Texas and the child is in Missouri.
Yes, and continuing child support owed after in states like Missouri where death is not a justiable cause for not paying support.
I'm not familiar with Missouri law, but I'm certain that the child support obligation would continue in such a case.
