TR, some states and/or title companies may require them to be filed as part of the deed transfer. In that case it would be a settlement charge. Although I will have to admit I'm not aware of any that do.
I do know some states, IN being one, require a POA be recorded if it is used to excute any document that has to be recorded or certified by a county or state official.
