Please excuse the advice of the previous poster, she is associated with parent's rights groups and is in most cases against grandparent's rights.
Please understand that since you are caring for the child it is reasonable to apply through your county probate court, for tempoary guardianship. Not knowing the county in which you reside I will provide informaiton about the process for Grady County which will be much the same, but contact your county for local rules. This is not the same as legal custodian or sole custody. You can use an attorney if you wish, but most courts are helpful in your situaiton and self-help is available.
TEMPORARY GUARDIANSHIP INFORMATION
If you have a child in your physical custody and you are not that child’s parent, you are without authority to enroll the child in school, obtain medical treatment for the child or otherwise control the child without first becoming the legally qualified Temporary Guardian of Person through the Probate Court of your county of residence. (Alternatively, you may contact the Juvenile Court about becoming the legal custodian of the child.)
If you wish to become Temporary Guardian of Person, you must comply with every legal requirement, including notice to both parents of the child. If either is deceased, you must furnish the death certificate or other proof of death. If whereabouts of both parents are unknown, you will need to go to Juvenile Court. You must furnish a certified copy of child’s birth certificate and your personal identification. Upon completion of the forms, you will need to telephone the Probate Court 229/377-4621) to secure an appointment time to file for temporary guardianship. If you have any questions about the proceeding, contact an attorney. Clerks can furnish forms to you but have no authority to explain the law to you. You will be required to sign a consent form for your criminal history to be checked.
