When you say the grandmother took custody, do you mean she raised the child or that your parental rights were terminated by a court? If there was a termination, you don't owe child support. If your rights were not terminated you can be sued for back child support by your DAUGHTER not the grandmother. The sue can be brought any time before your daughter's 21st birthday.
