- (b) [Paragraphs (b) through (f)](/cfr/14/47.13.md?p=b..f) of § 47.13 of this chapter apply to a conveyance made by, or on behalf of, one or more persons doing business under a trade name, or by an agent, corporation, partnership, coowner, or unincorporated association.

    - (i) It is signed; or
    - (ii) The grantor (a corporate officer or other person in a managerial position therein, where the grantor is a corporation) certifies in writing that the authority to sign shown by the power of attorney or other evidence is still in effect.
