No Contact orders regarding children are usually made in the Family Court. They don't need renewing as they usually run until the child is 18. A variation of such an order would only be possible if one of the parents made an application to the court but in these circumstances there's no way a court would revoke it.
There must have been Family Court proceedings in the past (although this hasn't been mentioned) to give Catherine the legal right to exercise parental responsibility and care for Ryan through a Residence or Special Guardianship Order. As such Catherine would be a named party in any further applications to the court so would know and obviously object.
I don't know if No Contact orders can be made within criminal proceedings but if so the conditions would surely not be less stringent than in the Family Court?
Also, given the severity of TLR's offences, if he were eventually released from prison he would be subject to a life license and conditions of that would be that he does not approach or try to contact Catherine or Ryan. Surely then he would not be able to see Ryan inside prison whilst still serving time?
Any Probation Officers on here to clarify?
