Letter of Authorization Requirement
The owner is the only person recognized by law to have “standing” to file an appeal. Appeals filed by individuals other than the owner or authorized agent may be denied for lack of standing. A notarized letter of agency (written letter of authorization) is required from persons or agencies, including attorneys who are not the owner of record but are filing an appeal on behalf of the property owner.
If the Notarized Letter of Authorization isn’t filed with the initial appeal, then the appeal will not be accepted at the Assessor Level, and you will have to wait until the following year to file an abatement.
