If my child's father is on welfare, will I still be a able to collect child support from him?

Whether a parent is homeless or rich in a mansion, child support is mandated by law and requried. You will need to file a child support order in court to start collecting payments from him. The worst possible scenerio is anywhere from $25/month or more. You mentioned you are seeking financial assistance which implies you can not afford a private attorney as private attorney for a child support case cost anywhere from $1,500 to $2,500. You can go to the family court in your county and speak with the court clerk for a Pro Bono attorney (someone that volunteers to gain experience.) Feel free to contact my office and speak with a case manager at 877-866-8665 or email help@smsattorneys.com as we do also offer reduced price services for PRO SE people who can't afford an attorney but able to represent themselves in court.
