no it goes to the mother.
yes
no not at the age of 20 years of the child. It may be of 25 years of the child
No, 11 years too late, and dangerous. I growing number of relationships with mother are destroyed by these actions when the adult child learns their mother had been lying about getting child support.
In this case, you can not force the mother to be in contact with her child, neither can the court, however, you are, and by all means, entitled to child support. All you need to do is, file for it.
If she's kept the claim current.
Yes, and the mother should request it retroactively.
Petition the court for a modification. If the back support was for any state aid the mother was on, then it can't be forgiven. If it isn't for that, then the mother can write a letter saying she forgives the back support owed to her.
No. The statute of limitations for child support arrears in New York is twenty years from the date of the default. However, in your case it seems that your mother never obtained a court order for child support. You have no cause of action.
arrears - yes; current (ongoing) support - yes, if the child is still a minor/dependent; retroactive support - maybe, it depends on several factors
no
