Rights of a 16 Year Old

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?

As the CP, you are actually obliged to facilitate the relationship between the child and the other parent. So if there is court order saying there will be X visitation, you make sure that the child is available for the other parent.

If the order does not address telephone visitation, you do not have to allow telephone contact.

Though frankly letting a 16 year old choose is a major mistake.
