File a complaint in the family court for child support.
I suggest that you contact your State's child support agency. When you get an interview with them, bring all the papers relating to your child support: birth certificates, acknowledgments of paternity, court orders, payment records, etc. Be polite but persistent. Good luck!
In addition Im 18, my brother's 17 and my sister's 15. we lived with our dad for 12 years and my mom paid child support for that time. Now my dad moved away because my mom was getting to him ( not gonna go in detail). we live with our mom now, and she is seeking child support from my dad, i DO NOT want that. Do we have a say in any of this ?
No, they are unrelated.
Absolutely not!
no yes when you turn 18
Only if they are marrying each other.
Yes, the father will need to pay child support in order to support his child. You are responsible for supporting your child until they reach the age of 18.
Not much you can do as the child but your mom can go to court and report him for not paying child support assuming there is a court order for it. The court have several ways to get someone to pay their child support.
In WI (as that is where I am) if Dad is in jail because of non-payment of child support arrears, Mom can get him out by writing a letter saying she does not want any of the monies due. Contact your Child Support Agency in the assigning county for more information.
If court ordered, yes.
Go back to court and tell it to the judge.
Step-child is only eligible for survivor's benefits from step-dad under special circumstances. If child moves in with biological dad, customarily dad is entitled to child support from mom. This very well might affect child's eligibility for survivor's benefits from step-dad. Social Security Administration would need to be notified of child's address change and representative payee would need to be changed (from mom to dad).
Only can speak for Arizona: when the parents are unmarried, the dad has no rights except to pay child support. Of course if the child is old enough and the mom does not object, the dad can keep custody.
