A CAO is applied for by the NRP. The RP already has the children, so doesn't need an order. People are often under the impression that if they (the RP) apply for a CAO then the NRP can be forced to see the children. This is not true. A NRP cannot be forced to be a responsible engaged parent. It is a one way street legally against the RP.
So, the NRP makes the application to the court. This will cost £215 but can be reduced of exempt based on NRP income or benefits.
If this is the father, first he must have PR for the children. He will have this automatically if he is named on the birth certificate after a certain date, (can't remember exactly but I don't think relevant any more for kids going through custody fights now.. think about 2002 ) or was married to the mother at the time of the birth. If neither he has to apply to the court for this, which is fairly straightforward if the mother does not dispute it.
The NRP and RP will then be obliged to attend mediation . They must arrange this themselves it's about £200 . If there is abuse on either side, or one party refuses to engage, the mediator can sign it off as inappropriate and you proceed to court.
Prior to court (or in our case) on the day !! CAFCASS (children's court service) will have a chat with both parties to establish the concerns of both parties. They will let the judge know the issues and recommendations for the proceedings. The important part is that the court tries to do everything in the 'best interests of the children' and is not usually remotely concerned about parental point scoring. They want to know if the NRP is someone that is a valuable and effective parent in the child's life. NOT if they were a good husband or wife. They start from the position that the child has rights to a relationship to BOTH parents IF it's not detrimental to their welfare to do so.
The CAO can be awarded on the day if it's straightforward. Sometimes if there has been no contact for a while they can make an order gradually introducing the child to the parent again. If there are allegations (real or malicious) of a nature that could be detrimental to the welfare of the child - then the judge can order certain steps that the NRP must take - for example, allegations of drink or drug abuse - monthly hair follicle and liver function testing for three months before returning to the court for a decision. Meanwhile, supervised contact can be awarded either at a centre of by a court appointed family member.
Once awarded the CAO makes the RP legally bound to 'make the children available ' to the NRP for the period determined by the court. Failure to do so means enforcement action can be taken by the NRP . This can in extreme cases of refusal to comply with the order result in arrest, community service orders and imprisonment.
