Yes, if in cases of unmarried persons paternity has been established. If pataernity is uncertain then it will be required by the court before a petition for child support can be addressed. Collection of child support for years passed is only possible if there was a valid court order for support relating to the year(s) in question.
no it goes to the mother.
no not at the age of 20 years of the child. It may be of 25 years of the child
Depending on the state, she has until the child turns 18 to 23 to file for up to 18 years retroactive support.
The mother cannot receive child support for a child who is over the age of 18. However, if the father owes money from before, that money has to be paid to the mother, even if the child is over 18. The father owes child support whether or not he sees 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.
arrears - yes; current (ongoing) support - yes, if the child is still a minor/dependent; retroactive support - maybe, it depends on several factors
