Ownership through nomination

Did owner/title holder leave a valid WILL? Your query does not mention about WILL so probate may be ruled out. On what grounds adverse possession may be contemplated! Did Nominee act as per MCS Act;92(b)….. You are aware this clause and its function.

The old arrangement was to save stamp duty.

Perspective: Check LOCALY from LOCAL counsel if suit jointly by possessor, society, for consent decree is possible. If other legal heirs have not come forward thee many years they may remain Ex.Party in the suit.

It is  felt that in such case stamp duty may be levied.

No will was made by the deceased. No succession certificate was obtained as it was not called for by the Society. In a hypothetical case if there was a will in 1962 was a probate necessary as a flat was not an immovable property under law in 1962?  No claim was made by other heirs. They knew for family reasons the property was to go to the nominee only. Now all the Class I heirs are dead.

Co-operative Housing Societies and nominations are almost  a 100 years old in Maharashtra (previously Bombay). Flats were transferred to nominees and such transfers were final all these years. Is there a pre-1980 judgment saying that a nominee is not an absolute owner?
