If you are dead, you cannot own land. It's a fact that has led to innumerable cases in India of people being registered dead and dispossessed of their property - and many have discovered that there is very little they can do about it, writes the BBC's Chloe Hadjimatheou.
In his late 70s, after the death of his daughter and son-in-law, he unexpectedly found himself raising two grandchildren. So, to pay for their upbringing and education, he sold some land he had inherited from his father in the village where he was born.
"The man I had sold the land to called me to say there was a legal case against me. He said my nephew was telling everyone I'd died and that an impostor had sold the land."
Yadav immediately travelled from Kolkata, where he lives now, back to the village in the Azamgarh district of Uttar Pradesh. When he got there, people were shocked to see him.
"They stared like they were seeing a ghost and said, 'You are dead! Your mourning rituals have been carried out!'"
