SDLTM01060 - Scope: What is chargeable: Pre-Completion Transactions FA03/SCH2A
To meet the conditions of FA03/SCH2A there must be a contract for a land transaction within FA03/S44: a contract that is to be completed by a conveyance. Before that ‘original contract’ is substantially performed or completed, the purchaser under that contract may enter into a further agreement as a result of which another person is entitled to call for the conveyance of all or part of the subject matter of the original contract. Such an agreement is a pre-completion transaction.
