Mr Wong Kar-fai lives in Vancouver. He wants his sister, Ms Wong Mei-ling, to sign the assignment of his flat at Flat 9C, Pine Court, Tsuen Wan on his behalf at completion. How should he appoint her?
Answer: By a power of attorney executed as a deed. An attorney who is to sign a deed (the assignment) must be appointed by deed. Why not the others: - Signed letter of authority: An ordinary signed letter is not a deed, and a power of attorney must be created by deed. - Oral instruction confirmed by a solicitor: An oral appointment cannot give authority to execute an assignment, which must itself be a deed. - Form 3: Form 3 is the estate agency agreement for a vendor appointing an estate agent to sell residential property. It does not appoint a private attorney to execute documents. Rule: Express agency can be created orally or in writing, but powers of attorney must be created by deed, and an assignment of land must be by deed.

Thinking a signed letter is enough to let someone else sign a deed such as an assignment.
