usually you put 2 cross lines, parallel to each other, 1 inch apart and in bold writing, write for verification only...use a ballpoint, not a marker..
always do this with your id card copies as well as utillity bills
there is first payment of bayana, then a stamp paper is signed with oath commissioner stamp and entered in register about terms of biyana only. then after payment another stamp paper worth atleast 100rs is signed and registered about payment.. then payment is made at same time, preferable via bank for security reasons, or a bank draft, never cheque... finally deeds are transferred then, and you are a billionaire.
for agricultural land, always meet your patwari, and ask about details first.. he will scare you to pee your pants, about fraud and tax and nAIB and PML N. but just ask procedure otherwise you may end up paying him lots of money.. since you are the seller, you dont need to pay him Shiit.. the buyer has to do his verifications and transfer. (or you CAN pay him in Shiit)
