When considering the sale of a leasehold DDA flat, it is crucial to understand the implications of converting it to freehold status. While the conversion is not legally mandatory, it is highly recommended for a hassle-free sale. Leasehold properties often face challenges, such as the need for DDA approval for transfers and additional conditions that can complicate the sale process. Buyers and financial institutions generally prefer freehold properties, which can lead to leasehold flats being sold at a discount and taking longer to close. As of January 2, 2026, the Delhi Development Authority (DDA) has halted new applications for leasehold-to-freehold conversions pending a review of associated charges, although applications submitted before this date will be processed at previous rates. Regarding the requirement for the original allottee's signature, if the seller is the original allottee or the flat has already been mutated in their name, they can proceed without it. However, if the property was acquired through an Agreement to Sell or General Power of Attorney (GPA) and the mutation is still pending, the original allottee's signature will typically be necessary.
