Requirements one by one
The records officer is the statutory secretary
Montana Code Annotated § 35-14-840(1)-(3) gives the corporation the offices described in its bylaws or appointed by the board consistently with them. It does not mandate a president, treasurer, CEO, or CFO title. It requires one officer to maintain and authenticate the records required by § 35-14-1601(1), and § 35-14-140(47) defines that function-holder as secretary.
The initial directors organize the corporation by appointing officers under § 35-14-205(1)(a). The board may elect individuals—defined as natural persons—and an officer may appoint additional officers when the bylaws or board authorize. The same individual may simultaneously hold multiple offices.
Officer functions include information escalation
Under Montana Code Annotated § 35-14-841, officer authority and functions come from the bylaws. To the extent consistent with them, the board or an officer whom the board authorizes may prescribe another officer's functions.
Montana Code Annotated § 35-14-842(1)-(2) separately requires good faith, reasonable care, and a reasonable belief that action serves the corporation's best interests. Within the officer's functions, the officer must inform the appropriate superior, board, or committee of material corporate information and must escalate a believed actual or probable material legal violation or material breach of duty. This page states those duties without predicting liability or a disputed fiduciary outcome.
Written resignation may depend on future events
Montana Code Annotated § 35-14-843(1) requires written notice delivered to the corporation. Under § 35-14-141(3), delivery may be made to the registered agent at the registered office or the secretary at the principal office shown in the latest annual report. General notice-effectiveness rules apply unless the resignation delays effectiveness, including by one or more future events.
If the board or appointing officer accepts the delay, that actor may fill the pending vacancy before it occurs, but the new officer must wait to take office. The statute states no withdrawal rule.
Removal follows the delegated appointment chain
Montana Code Annotated § 35-14-843(2)-(3) permits removal at any time, with or without cause, by the board; by the appointing officer unless the bylaws or board say otherwise; or by another officer authorized by the bylaws or board. A successor to the original appointing officer also qualifies. The section states no special vote, notice, or hearing.
Under § 35-14-844, election or appointment alone creates no contract rights. Removal does not affect the officer's existing contract rights, if any, and resignation does not affect the corporation's existing contract rights with the officer.
Internal and public rosters cover different officer groups
Montana Code Annotated § 35-14-1601(1)(f) requires an internal list of all current directors and officers with business addresses. The public annual report under § 35-14-1621(1)(d) instead lists directors and principal officers with business addresses. Its information is current when signed, and the filing window runs January 1 through April 15 beginning in the year after incorporation.
The officer part states no fixed term, holdover, failure-to-elect consequence, general vacancy term, or acting-officer route beyond the accepted delayed- resignation mechanism.
What trips people up
Montana requires a written officer resignation even though the general notice section permits oral notice when reasonable in other settings. The officer- specific writing rule controls.
The resignation delay can turn on future events, not only a calendar date. Advance successor selection still requires acceptance by the board or appointing officer, and the successor cannot start before the vacancy occurs.
The public annual report lists principal officers, while the internal roster lists all current officers. Filing the report also does not itself appoint or remove anyone.
Common questions
Must a Montana corporation have a president and secretary?
It need not create a president title under § 35-14-840. It must assign the required records function, and the Act defines the officer holding that function as secretary.
Can one person hold every office?
Section 35-14-840(4) permits the same individual to hold more than one office. The bylaws, assigned functions, and transaction-specific signature rules still need separate review.
Can an officer remove someone the officer appointed?
Yes, unless the bylaws or board provide otherwise. A successor to the appointing officer also qualifies, and another officer may remove if authorized.
Does officer status automatically create employment rights?
No. Section 35-14-844 says election or appointment alone creates no contract rights. Section 35-14-140(16) defines employee to include an officer but not a director; that classification does not decide a particular employment remedy.
