An experienced salesperson is preparing stamp-duty advice for a client's proposed property sale. His internal checklist was accurate when prepared, but an official notice now identifies a rule change that may affect the transaction. He has completed his required professional education and can access the current official guidance. No advice has yet been given. Which course best meets the standard of professional care?
Paragraph 4(2) of the Code requires familiarity with relevant laws and continued awareness of developments affecting property transactions. Paragraph 5(1) requires diligence and care in the work itself. Completing education or having an accurate historical reference does not establish that advice for this transaction is current. Equally, a new rule cannot simply be applied without checking when and to which transactions it applies. Checking the official guidance against the client's facts, and seeking appropriate expertise if necessary under paragraph 14, addresses the actual risk. The question tests updating professional advice, not any particular stamp-duty rate or holding period. Whether careless advice subsequently creates civil liability additionally depends on the other negligence elements.
