I'm a single mother of one. I currently have the father on child support. I'm trying to join the airforce but when your a single mother you have to give temporary custody to someone willing to watch her until my tasks are complete. I don't want to give temporary custody to anyone. So if I offer my childs birth father a deal to take him off child support if he agrees to watch her during my studies what do I need to do to make sure he abides & follows the agreement. Is this possible? Can I sign any type of contract.
