How Do You Put a Manager/ Representative/ Agent Into Lease?

[John Woodman]

My wife basically manages a few properties for family members who now live out of town. So when one comes up for rent, we are taking over advertising it, showing it to prospective tenants, selecting tenants, and so forth.

Things have not been very organized in the past, and we are working on a better lease agreement. A standard lease agreement would work, except it's likely to be my wife signing on behalf of the actual owner, rather than the actual owner himself (or herself).

How do we put this into a lease agreement - that my wife (or my wife and I) are signing and acting on behalf of the actual owner of the property?

Thanks!
