The county department of social services or the state department that collects child support payments (not the DA, who has nothing to do with civil divorce or child support enforcement) is not a messenger service and cannot/will not ‘pass a message along’ to a non-custodial parent. Most ‘contact’ between the county and the payer is through payroll deductions or bank garnishments. The custodial parent has no right to know where the NCP works or lives. The county is only concerned with whether the payments are being made. Think about it from the other side. What if the NCP parent wanted to contact the CP but there was a court order of protection? Do you think the county should just pass along the contact information?
You think the university is going to send a message through the DA to an unknown NCP?
This would never happen.
