Agent signing lease on behalf of landlord

[David Powers]

Hey eveyone! 

I wanted to get other agents thoughts on this. I am a broker in Missouri and I have a client that I handle leasing for (not management)  that prefers that I sign the lease as a "authorized agent" on his behalf. Looking through our listing agency agreement with him I don't see any verbiage that mentions the ability to sign on his behalf.

Has anyone experienced this? I have no problem signing on this behalf but just want to make sure I can legally do that without raising a red flag to the real estate commission if audited.
