complicated in OKLAHOMA

[tressy]

What is the name of your state (only U.S. law)? oklahoma
OK here goes: We have had our great-nephew living with us since January 2008. He is now 15 months old.
His mom was busted for selling narcotics to undercover officers...when she was busted, she had him with her. After very long drawn out court appearances, she got a plea bargin and no jail time in June. Probation, drug classes, counseling, and AA....and a felony charge is what she got.
She has made NO attempt to come get him, does not pay for anything for him and has only called 3 times in 3 months....
[b]at what point could we look in to terminating her parental rights?
[b]Baby's dad is unknown and from out of state.
She brought me his birth certificate, ss card & shot record in July.
I just really feel like something needs to be done...but I'm not sure what to do. I just don't feel like I'm gonna come out ahead on this deal...if something isnt done soon. And especially for the baby involved, its not fair to him.
Thanks for any advice anyone can give. I appreciate it!!

You cannot terminate her rights. You can always sue for custody however.
