How can a legally adopted person get his or her name changed in the documents?
I was legally adopted when I was 3 years old by my biological father's unmarried sister. Adoption deed is legal & registered.I also have a pension account under her name. She died when I was 7. My biological father is my legal guardian. My school and college records have my biological parents name and also in all the other documents such as pan card, voters id, drivers license, aadhaar card. I have applied for passport. Advice me what should I do? All the documents have my biological parents name. Do I need to change all the documents in her name? Can I now change the documents especially passport?
