Resale of tamil nadu slum clearance board

If the land/flat was given on lease-cum-sale or allotment basis, generally the allottee cannot sell or transfer the property for a lock-in period (commonly 5–10 years or more, depending on the scheme).
The allotment deed will clearly state the restriction period.
Check if the allottee has been issued a sale deed / patta / absolute ownership document by the Board.
If the Board has only issued an allotment order or possession certificate, the allottee is not yet the full owner and cannot legally sell.
Even after the restriction period, in many cases Board’s permission/NOC is required for transfer.
If you purchase during the restricted period, the transaction is voidable and you may face cancellation by the Board.

The query is short of material facts.

Hi sir,thanks for the reply. what material?

The allottee cannot sell his land, which was allotted by the TMSC Board, now called as Tamil Nadu Urban Habitat Development Board.

Such allotments are conditional with restricted rights to transfer during a specified period. Unless those aspects are disclosed there could be no meaningful suggestion.
