When the seller sells a portion of a property it is known as a sale of part. A portion of the garden of a house may be sold, certain portions of a plot of land may be sold, a landlord might grant new leases of a certain portion of a huge block. The special conveyancing of sales in part are to be taken into consideration. It has to be checked carefully whether any lender’s permission is required or not. It is also to be taken into consideration whether the permission of the other co-owners are to be taken before selling, renting or leasing out a portion of a property.
