What is AEO-011?
AEO-011: Agent Authorization is the San Bernardino County Assessor-Recorder-County Clerk form, printed with the title Appointment of Agent, by which a property owner authorizes a named agent to represent them in property tax matters for listed property.
The form has three blocks. The owner block gives the owner's name, addresses and contact person, and marks the property covered: all property listed for the owner in San Bernardino County, all real property, all business and personal property, or another description. The agent block gives the agent's name, addresses and contact person. The authorization block holds the owner's signature and date.
Between them, the owner chooses the powers granted. One option is a general power to represent the owner in property tax matters concerning the property. The other is a list of specific powers: filing of Assessor's forms; filing assessment appeal applications and representing the owner at appeal hearings for a stated assessment year; receiving confidential information; negotiating and resolving assessment matters; and changing the mailing address for property tax notices and other communications. An "Other" line allows a power not listed.
The county's forms page lists AEO-011 under the Assessor, among forms such as the Assessment Appeal Application and AOS-058: Request for Change of Address. The form carries the revision mark AEO 011 Rev. (01-25).
Who needs to file AEO-011?
Property owners in San Bernardino County who want another person to handle property tax matters with the Assessor-Recorder-County Clerk use this form to appoint that person as their agent.
The owner completes the owner block and decides how much authority to give: a general power to represent the owner in property tax matters concerning the property, or only the specific powers checked on the form.
Who signs:
- An individual owner signs for themselves.
- For other owners, the form names a partner, or an LLC Manager, or a corporation officer whom the Board of Directors has designated in writing to sign on behalf of the corporation.
- The signer prints their name and title below the signature line.
The agent is the person or business named in the agent block; the form asks for the agent's mailing address, physical address, contact person and telephone number, and the agent does not sign it. The form is about property tax matters concerning the listed property and does not describe any other kind of representation.
When to file AEO-011
Complete AEO-011 when you want an agent to act for you in property tax matters with the Assessor-Recorder-County Clerk. The form prints no due date of its own. If you grant the power to file assessment appeal applications and represent you at hearings, the form asks you to write the assessment year to be appealed, so have that year ready before you sign. If you grant the power to change the mailing address for your property tax notices, read the note printed on the form first: these notices can affect your legal rights, and the affected offices are not required by law to send you duplicate copies.
How to fill out AEO-011
Enter the owner's name and addresses
In the owner block, write the owner's full legal name, mailing address, and physical address, each with city, state and ZIP code.
Add the owner's contact person
Enter the contact person and title and the telephone number in the owner block.
Mark the property covered
Check the property the appointment covers: all property listed for this owner in San Bernardino County, all real property, all business and personal property, or Other with a description.
Choose the powers you grant
Check the general power to represent the owner in property tax matters concerning the property, or check each specific power the agent should have: filing of Assessor's forms, assessment appeals, receiving confidential information, or negotiating and resolving assessment matters.
Enter the appeal year if needed
If you grant the appeal power, write the assessment year to be appealed. The same power includes giving you a copy of the appeal application filed on your behalf.
Decide on the mailing address power
Check the power to change the mailing address of your property tax notices only if you intend it. Read the printed note first: these notices can affect your legal rights, and the offices need not send duplicates.
Add any other power
Use the Other line under the powers only for a power the form does not list, and describe it.
Complete the agent block
Write the agent's name, mailing address, physical address with city, state and ZIP code, the contact person and title, and the telephone number.
Sign, date and print name
Under Authorization, the owner, a partner, or an LLC Manager or designated corporation officer signs and dates, then prints their name and title.

Common mistakes to avoid
- Leaving the property section unmarked, so the form does not show whether the agent covers all property, all real property, all business and personal property, or something else.
- Checking the assessment appeal power without writing the assessment year to be appealed.
- Granting the power to change the mailing address for property tax notices without noting the form's warning that these notices can affect legal rights and that the offices need not send duplicates.
- Having someone sign who is not the owner, a partner, or an LLC Manager or corporation officer designated in writing by the Board of Directors to sign for the corporation.
- Signing without printing the signer's name and title in the space below the signature line.
- Omitting the date next to the owner's signature.
- Leaving out the agent's contact person, telephone number or addresses in the agent block.
- Marking both the general power and a list of specific powers without a clear intent, instead of choosing the scope you actually want the agent to have.
