Wapda Town Lahore

Dear,

I am in the process of purchasing a 1 kanal plot in Wapda Town Lahore. Property dealer told me that owner has lost the original file. Now he has applied for duplicate file. Is there any problem to buy a plot with duplicate file in Wapda Town Lahore. Kindly also tell me what kind of documents I will get after buying this property and what extra cost have to pay in order to transfer this plot.

Regards,

Reluctant buyer
