Which step involves the giving of a professional undertaking by the seller's lawyer to the buyer's lawyer?

• A. Release of the seller's part contract to the buyer's lawyer on exchange of contracts under Law Society Formula C
• B. Provide title deeds
• C. Provide mortgage deeds
• D. Confirm completion date

Answer: (A)

The step being tested is the moment contracts are exchanged and the seller’s solicitor gives a formal undertaking to the buyer’s solicitor. Under the Law Society Formula C, this is shown by releasing the seller’s part of the contract to the buyer’s solicitor at exchange. That undertaking is a binding promise from the seller’s solicitor to progress to completion and to provide the necessary documents and actions (such as transferring title and dealing with required deeds) on completion.

Other options describe actions that happen during conveyancing but are not the undertaking itself: providing title deeds or mortgage deeds are about delivering documents, and confirming the completion date is a contractual detail—not the undertaking given at exchange.
