I am 29 years old, male . I don't have any family or relations. I take care of my living by myself. I have a sister( She is not my relation in any way. However she is my only well wisher. I consider her as my own sister and so she considers as her own brother ) .She is elder than me. She is married and has a girl child . Her partner left her alone and she is now working and struggling to bring up her child. She has father, mother and a brother , but no one even think of supporting or helping her rather they blame her for what she is now.
I am thinking of adopting( i am not sure if this is the rite word ) her as my sister legally .Kindly let me know if its possible to leggally adopt a sister. If yes, advice on the procedures would be of real help.
Thanks a lot in advance.
