Relative cheated and took half of our property. What to do?

To enable me to reply to your query, you need to provide information like - what is this deed, the year/date of such deed, when did you learn about such a deed, who is having the title deed to such a land, in whose name the land was recorded at that time, what is this BL.

Well there are two ways of dealing with this, firstly you will have to file a suit for declaration and permanent injunction concerning the title of the land by challenging the validity of the deed made and Secondly you can also initiate criminal proceedings which may also include trespass, criminal breach of trust etc.

You can file criminal complaint for cheating. First approach the police for filing of FIR. If they do not register, write to SHO followed by DCP. If it is still not registered, move court under S156 CrPC.

You can also file civil suit for declaration and permanent injunction in relation to that land.
