Relinquishing one's parental rights does not terminate one's child support obligation.
Yes, the right of a parent to be in his or her child's life has nothing to with whether or not he or she is paying child support. The court sees them as two entirely different issues.
Yes, until/unless the child is adopted.
No.
Child support and visitation are two separate issues. The father has the right to request a visitation schedule with his child. Visitation is not dependent on paying child support.
well i was looking to see how signing over my parental right works in Oklahoma
Your question is unintelligible (what does the Navy have to do with it?). However, in Minnesota, termination of parental rights does not terminate child support obligation unless the child is being adopted.
In general, the oldest child's right to support is not affected by the existence of younger children.
Yes. Parental rights are yours and you can sign them away. You cannot, however, sign away the child's rights, and one of those rights is the right to support. If you're signing away your rights so that someone else may adopt the child, once they do so you should be absolved from the responsibility to keep paying child support.

Yes, unless/until the child is adopted.
In general, parental rights are terminated either preparatory to an adoption, or after a trial in which it is determined that the parent is unfit. In any case, termination of parental rights does not, in itself, terminate child support.
