Property dispute

Dear brother, there is no doubt  you are entitled 50% undivided share in land and building (first floor) and your brother can not claim apart from his share ( i.e 50% ) Sktch map attached or not that is immaterial. pl.approach the concernerned revenue authurities to mutation of revenue records in your name as per will with respect of your 50% undivided share in land and buliding ( First Floor )

Never misunderstand the other citizens and law makers are foolish.  The mutation in poperty, tax payment, application for electrcity, disclosing of income on such first floor or such declarations in public records, non payment of rent etc, gives adequate strength to first floor owner'\occupier and he can claim even adverse possession.

Why 'suppose'? Is it not a real issue?

Then why 'suppose'. Anyhow, please post simple facts devoid of assuptions and presumptions and subjective personal opinions.

Adverse possession is a present law that states that whoever is in possession for more than 12 years in his own name without paying a single paisa as rent, continue to pay tax and as known to all he is the possessor of that apartment, and if the land is ancestral, the FIRST GROUND OWN CAN claim adverse possession as owner.  I am not an expert to state as to whether adverse possession is proper or not as it is controversialal in many countries.   There is a case in Delhi, where a sister was given a self acquired property to a widowed brother's wife, she claimed it as own and dragged the litigation during entire life time and the court passed strictures on that issue.
