1. Is he the child's legal father? yes he is
2. Are there any court orders in place? no, i have never filed for support, i had to make do with what he gave me
3. WHERE exactly does he live? guyana
1. Okay.
2. Then he's never been legally obliged to pay a single cent of child support - you're lucky you've received ANYTHING.
3. Here's your problem. You have to file for child support. And to do that, you have to be able to have Dad served. Good luck getting that done in Guyana.
Since you're already getting money from him, I'm not entirely sure what you think you'll accomplish.
There would be, I think, a most EXCELLENT chance of him simply stopping the cash flow and leaving you with nothing.
