| Sorry, this was not answered sooner. Sometimes, these things get missed.
You are going about this backwards. FIRST he needs to get custody changed. Then he applies for a modification of the support order due to the change in custody.
I'm not sure what papers the mother has to sign, but if they were issued by a court, then he should have been going back to court to force her to sign.
After the custody issue is resolved, he then applies for the mopdification of the support order (this can all be done in one hearing) and also applies to the court to order the ex to return any amounts overpaid. Depending on the history of the case, the judge may or may not order the refund.
If he doesn't have a lawyer, he should get one.
P.S. I responded to your comment and PM in the thread you posted it. |
