Sra ownership

Dear Sir,

I m liivng in a SRA room & it is in my FATHER name who has expired.

Later on nominee my mother she has also expired.

Now, I being the elder one i m the nominee at present.

 10 yrs have been completed of this oroject a few days earlier.

Now, the problem is that my BROTHERS WIDOW is residing with me with her daughter.

She has brought a letter from SRA & submitted to the society  stating that her name should also be added as a nominee.

Please let me know who will be legally owner of the room,

& is the SRA documnet valid for her.

& if the society not supports me where I should launch a complaint.

Please also guide me which docs are required FOR me to submit the Society.

THANKS & REGARDS,

NARPAT SINGH MOMAVALA
