My question involves a child custody case from the State of: Oklahoma. I have full custody of a 16 yr old. Visitation is 8 hrs monthly supervised. However she (the child) now doesn't always want to see or talk to the non custodial parent due to a variety of legitimate reasons. yet he is very very very persistent. calls and calls and calls and calls. Does she HAVE TO talk to him? What can I do to stop the calls if anything?
