Aw MAN you've let another month pass. Get a lawyer, You cant' afford to continue to pay child support and not get any. The price of the lawyer will be paid for by the savings.... let's say you paid $500 a month (and now not only will you not owe that, but hse will owe YOU $500 a month) by allowing this to sit for a month, you are now $1000 in the hole. That $1000 would have been worth it to pay an attorney to get this done LAST month.
If you're having trouble finding what you need online and the court officer said you need a lawyer, it might be that you do need one. Some people can't negotiate the highly regulated court system on thier own (like others with their taxes, some people just NEED a tax guy, no matter how little money they make, they need someone to do the forms for them & make certain it's done right... not an insult, just saying your skills are better in other areas than in negotiating the legal things on your own). It soudns like YOU NEED a lawyer.
If only for the initial filing. DO NOT LET THIS WAIT.
