Where an agent executes a contract (including a deed) in its own name on behalf of an unidentified or non-existent principal, there is an arguable basis for the agent to sue on the contract as principal, particularly where the identity of the principal is immaterial to the other contracting party. The absence of a power of attorney does not of itself render the agreement invalid; the question of validity depends on wider common law principles of agency. Section 84 of the Property Law Act 1969 (WA) has no application where there is no power of attorney at all.
