Not so simple process.
1 do you know the location of the land? Who has kabza of the land? Does it come in agri land or sehari land?
do you have papers stating it is in your mother's name ? (Registry or intaqaal date and photocopy)
How was the property transferred to your mother name ? By patwar or by court order and succession certificate?
If land comes in sehari zameen then you will need succession certificate but if its agricultural land then patwar can do intaqaal(transfer) on your name but you will have to pay money to patwari amd tasheel dar for sure.
But If you dont have kabza of land and some other party is in possession then there could be a problem for sure..
Take some person with you who know these matters... other wise its a hell hole.
