Open files are common in Pakistani housing societies, including large projects such as Blue World City. They can be traded legitimately, but they are also a frequent source of fraud. This guide explains what an open file is, how it works and how to protect yourself.
What is an open file?
An open file is essentially a registration form issued by a housing society that has not yet been assigned to a buyer. Once a customer fills it in and the dealer submits it to the society, the file becomes closed. A plot is only allocated against a closed file.
How an open file works
- Dealers or marketing agencies buy open files from a society in bulk, usually below the full price.
- They advertise the files and look for buyers.
- When a buyer is found and the form is correctly completed and submitted, the society records a plot entry against it and the file is closed.
- The society marks that land as sold, and the buyer learns the plot’s location at the next balloting.
- If files are not sold in time and the society’s land is fully sold, the unsold files must be returned to the society within a set period, which refunds the initial amount paid for them.
Why open files carry risk
An open file that is not sold in time loses its value: the holder can only recover the initial amount originally paid to the society.
The problem is worse when informal dealers sell open files to ordinary buyers at inflated prices, promising large future gains. If those buyers cannot sell the files on, they must return them to the society, which refunds only the original amount paid by the dealer — leaving the buyer with a loss.
Marketing agencies that buy files in bulk may receive installment discounts or merging offers from societies to offset such losses. These offers are generally not available to informal dealers or to individual buyers.
How to avoid open-file scams
- Buy only from the society itself or from established, authorised marketing companies with a permanent office.
- Avoid informal dealers with no fixed place of business — many scams are run by individuals who move on after a few sales.
- Ask the society to confirm that a file is genuine and how its status will change once you buy it.
- Be wary of claims that an open file will deliver large profits.
- Pay only into official company accounts and keep every receipt.
