The father of my son won't pay child support

If you have an existing child support order from the court and he does not pay it you have several options depending on your situation.  If you filed with child support services, then it is their responsibility to enforce the child support payments.  If you filed for child support with the family court then you can file a 'contempt order' for failure to follow the court order, or you can execute a collection order by doing a wage assignment etc. If you do not have any court orders and are not married to the father then you would need to file a paternity action (petition to establish parental relationship) which will address custody, visitation and support for your son.
