When my ex disappears, I have to do the detective work to find him (the CS doesn't do anything). Luckily since I am in contact with his family, eventually I find out little tid-bits of information that lead me to where he is. Do you know the town where your CP lives???? Your
child support office is supposed to check with the post office to see if the CP filed a change of address. This is what my CS office told me, but my ex never files a change of address. Technically, there's no valid address for my ex.
I know that it's frustrating and it's not fair, but unfortunately I don't think that there's much that you can do about it except to bring it up the next time you go to court.
Is there a reason that the CP doesn't want you to know the address or phone number. Have you been able to visit your
SS in the last 2 months?
