A fiduciary deed is a deed used to transfer property when the grantor is acting in his official capacity as a trustee, guardian, conservator, or executor, etc. A fiduciary deed typically only warrants that the fiduciary is acting in his appointed capacity and in the scope of his/her authority and doesn’t guarantee the title of the property. Fiduciary deeds are governed by state laws, which vary by state, and may provide an exemption from transfer taxes for fiduciary deeds.
