I believe my original reply still stands.. Also, best to post updates to the same thread as it helps other people to help you..
Here is my other reply...
The only way you can help is financially. That is to pay for an attorney to file for a change of custody on the grounds of abuse. At 15, the child will probably get a chance to speak and providing he does not exaggerate, a judge would consider his request.
Also, if the bio dad is refusing to obey a court ordered visitation schedule then that is more reason to proceed.
I may get beat for suggesting this.. but another option, if the child is strong, is to pack his bags and go live with his mother. Yes, the biodad can file a police report, yes the police will come knocking on the biomom door.. but this is where the child needs to be strong and inform the police of the abuse and that he is not leaving. The biomom needs to step back and not interfere or it will be seen that she is stopping him and it may go against her in court..

SMILE - Start Making It Livable for Everyone
Divorce is a process over which children have no control. Children should not be its victims.
When parents are under stress, it is harder to be in touch with their children's pain and anguish.
It takes time, effort, and planning on the part of the parents to be able to provide for the children's needs.
In the crisis of divorce, parents may put their children on hold while they attend to adult problems first.
Sometimes separating/divorced parents find that their roles and expectations are undefined and cloudy.
If handled properly, divorce need not be devastating for children.
