text: i want to know how do i divorce my adopted parents? i am going to be 21 years old and i was adopted when i was about 5 years old in grenada.  i have always lived with my biological mother.  i want to know how i can get my adopted mother's name off my birth certificate and put back my biological mother name onto my birth certificate? since you are above 18, it doesn't really matter for most issues.  but this is a personal choice.  you should contact your local family court in your county for the proper procedures to file paperwork to make this change.
