Is it legal to purchase the freehold property in noida?

If your asking that is freehold property legal in noida then you should know that authority has not sanctioned any freehold property, whether land or flats in Noida and Greater Noida. All properties, including authority flats, societies, or land, are leased. If someone claims that the land is freehold and assures you there won't be any issues with the authority in the future they are misleading you and taking advantage of your trust.
