The Montana Department of Revenue Form AOS, known as the Affidavit of One and the Same, is a formal legal document designed to clarify and rectify identity inconsistencies in official records. This affidavit is typically required during application processes—such as for alcoholic beverage or gambling licenses—when an individual’s name appears differently across various supporting documents. For instance, if a driver’s license uses a full middle name while a background check uses only an initial, or if a maiden name is used on one form and a married name on another, this affidavit serves as a sworn statement linking those identities. By signing this document under oath, the affiant legally attests that the different names refer to the exact same person, thereby resolving potential confusion and preventing processing delays with the state agency.
How To File The Affidavit
This form is rarely filed as a standalone document; instead, it is usually submitted as a supporting attachment to a larger application or request being made to the Montana Department of Revenue, specifically the Alcoholic Beverage Control Division. Once completed and notarized, you should include the original affidavit with your primary application package. If you are asked to provide this form after already submitting an application, mail the completed document to the specific department or case manager requesting it. For general submissions, it is typically sent to the Alcoholic Beverage Control Division at the Department of Revenue in Helena. Always ensure you keep a copy for your personal records before surrendering the original.

How To Complete The AOS Form
Affiant Statement
Date Of Execution
At the top of the form, locate the line that reads “Dated this.” Enter the current day of the month, the name of the month, and the last two digits of the year in the respective spaces to establish when the document is being created.
Affiant Name
On the line following “I,”, print your full legal name. This identifies you as the person making the sworn statement.
Identity Clarification
The core of the affidavit is the statement “state that [Name] and [Name] is one and the same person.” In the first blank space of this sentence, write one version of the name in question (e.g., your name as it appears on your birth certificate). In the second blank space, write the other version of the name (e.g., your name as it appears on your driver’s license or application). This legally links the two variations.
Signature And Venue
Venue
Under the header “State of Montana,” find the line labeled “County of.” Enter the name of the specific county where you are physically located when signing this document.
Signature
Sign your name on the line labeled “Signature.” This must be done in the presence of a notary public; do not sign it beforehand.
Printed Name
Clearly print your name on the line directly below your signature to ensure legibility.
Notary Public Section
Notary Block
The final section of the form is reserved exclusively for the notary public. Do not write in this area. The notary will enter the date they witnessed your signature (“Subscribed and sworn to before me this…”).
Notary Signature And Stamp
The notary will sign their name on the designated line and affix their official notary stamp in the box provided at the bottom of the page. This official seal makes the affidavit a legally binding document.
