Key Takeaways

-   Bylaws are never filed with the Montana Secretary of State — they're an internal governance document you keep with your corporate records
-   Montana allows a board of just one director regardless of how many shareholders the corporation has (§35-14-803(1): 'A board of directors must consist of one or more individuals') — there's no multi-director minimum tied to shareholder count.
-   Required officer positions: no specific named titles at all — §35-14-840 uses the modern, flexible approach: 'A corporation has the officers described in its bylaws or appointed by the board,' without requiring a 'president' or 'secretary' by name. Your bylaws simply need to describe whatever officer structure the corporation actually uses.
-   Absent a contrary bylaw provision, Montana's default board quorum is a majority, but with a real floor: articles or bylaws may NOT set board quorum below one-third of the fixed or prescribed number of directors (§35-14-824) — a specific numeric limit that not every state imposes. The default shareholder quorum is a majority, adjustable by the articles (§35-14-725).
-   Under Montana law (§35-14-1020), the board may amend or repeal bylaws unless the articles or a shareholder-adopted bylaw reserves that power to shareholders — the standard modern Model Act default, with the board controlling amendment absent a specific reservation.
-   Same-day bylaws drafting available through LLC Attorney as part of formation, at no markup on state fees

Montana's Business Corporation Act is a near-verbatim adoption of the modern Revised Model Business Corporation Act, which makes it one of the more predictable states to draft bylaws for — no automatic cumulative voting, no reversed bylaw-amendment default, and no legacy grandfather clauses complicating the picture.

This guide covers exactly what to include in a Montana corporation's bylaws in 2026 — the difference between bylaws and your Articles of Incorporation, Montana's default rules for directors, officers, meetings, and voting, and the one numeric floor worth remembering: board quorum can never be set below one-third of the board.

## What Are Montana Corporate Bylaws?

Bylaws are your corporation's internal rulebook — they govern how the board, officers, and shareholders operate day to day. Unlike your Articles of Incorporation, bylaws are not filed with the Montana Secretary of State — they're an internal governance document you adopt and keep with your corporate records.

Montana law (§35-14-206(1)) requires the incorporators or board of directors to adopt initial bylaws, but nothing in the Montana Business Corporation Act requires filing them with the Secretary of State or any other agency — they stay in your corporate records, not on the public record.

## Bylaws vs. Articles of Incorporation in Montana

Your Articles of Incorporation are a short public document filed with the Montana Secretary of State under the Montana Business Corporation Act (Mont. Code Ann. Title 35, Chapter 14) that creates the corporation's legal existence — name, registered agent, and authorized shares. Bylaws are a longer, private document that never gets filed anywhere; they spell out how the corporation actually runs.

Amending your Articles of Incorporation requires a formal filing with the Montana Secretary of State and, in most cases, shareholder approval — amending bylaws requires no state filing, and the board can typically act on its own unless your specific bylaws or articles say otherwise.

## Board of Directors: Montana's Default Rules

Montana allows a board of just one director regardless of how many shareholders the corporation has (§35-14-803(1): 'A board of directors must consist of one or more individuals') — there's no multi-director minimum tied to shareholder count.

Absent a contrary bylaw provision, directors are elected annually — Montana's Act is essentially a verbatim adoption of the current Revised Model Business Corporation Act, so staggered (classified) boards are permitted if the bylaws establish one, but that's not the default.

If a board seat becomes vacant and your bylaws don't specify a filling procedure, Montana's default follows the standard modern Model Act pattern, with the remaining directors filling the vacancy.

Yes — Montana allows one person to be the sole shareholder, sole director, and hold every corporate office simultaneously. Nothing in the Act prohibits it, consistent with the flexible modern Model Act structure Montana adopted.

## Required Officer Positions in Montana

no specific named titles at all — §35-14-840 uses the modern, flexible approach: 'A corporation has the officers described in its bylaws or appointed by the board,' without requiring a 'president' or 'secretary' by name. Your bylaws simply need to describe whatever officer structure the corporation actually uses.

Montana places no restriction on one person holding multiple officer titles simultaneously — a sole owner can hold every office the bylaws create, which is common for single-shareholder Montana corporations.

## Meeting, Notice, and Quorum Defaults

Montana requires an annual shareholder meeting (§35-14-701(1)) to elect directors and transact other business, following the standard modern Model Act pattern.

Absent a contrary bylaw provision, Montana's default board quorum is a majority, but with a real floor: articles or bylaws may NOT set board quorum below one-third of the fixed or prescribed number of directors (§35-14-824) — a specific numeric limit that not every state imposes. The default shareholder quorum is a majority, adjustable by the articles (§35-14-725).

Montana requires 10 to 60 days' notice of shareholder meetings absent a different bylaw provision (§35-14-705(1)). Board meeting notice is largely left to the bylaws to define.

Montana permits unanimous written consent in lieu of a meeting by default (§35-14-704(1)). Less-than-unanimous consent is also available if the articles opt into it (§35-14-704(2)) — except that if the articles authorize cumulative voting, director elections can never be conducted by less-than-unanimous consent.

## Voting Procedures Your Bylaws Should Address

Montana's default voting standard for board and shareholder action is a majority of those present at a meeting where a quorum exists. Directors are elected by plurality by default (§35-14-728(1)).

Montana is a clean baseline state on this point: cumulative voting requires an Articles opt-in only, with no automatic right whatsoever. §35-14-728(2) states plainly: 'Shareholders do not have a right to cumulate their votes for directors unless the articles of incorporation provide for that right.' Unlike Minnesota, North Dakota, Missouri, Nebraska, North Carolina, or Mississippi — all of which have some automatic or date-dependent cumulative-voting wrinkle — Montana simply requires the standard opt-in, making it one of this batch's genuinely 'textbook' states on this issue.

Montana shareholders may vote by proxy, and your bylaws should specify how proxies are appointed and revoked if you want rules different from the statutory default.

## Stock and Shareholder Provisions

Montana permits both certificated and uncertificated shares under the standard modern Model Act mechanics — your bylaws should state which approach the corporation uses and how share records are maintained either way.

Absent a contrary bylaw provision, Montana's default record date follows the standard modern Model Act pattern — board-set, with a statutory fallback if none is fixed. Most bylaws set this explicitly to avoid ambiguity.

Montana permits reasonable share transfer restrictions, enforceable if reasonable and conspicuously noted on the certificate (or equivalent uncertificated-shares notice) — a standard modern Model Act rule.

## Indemnification of Directors and Officers

Montana follows the standard modern two-tier pattern: permissive indemnification authority with defined exceptions (§35-14-851), but MANDATORY indemnification for a director who is 'wholly successful, on the merits or otherwise' in defending a claim (§35-14-852) — the same structure used by most of the modern Model Act states in this research batch.

Montana separately authorizes D&O insurance purchase (§35-14-857), independent of the corporation's statutory indemnification power — your bylaws' indemnification section and any D&O policy should be reviewed together.

## How to Draft Bylaws for Your Montana Corporation

### If You Do It Yourself

**Step 1 — Confirm your Articles of Incorporation are filed first.**

Bylaws govern a corporation that already legally exists — file your Articles with the Montana Secretary of State before drafting bylaws around them.

**Step 2 — Set your board of directors structure.**

Montana allows a board of just one director regardless of how many shareholders the corporation has (§35-14-803(1): 'A board of directors must consist of one or more individuals') — there's no multi-director minimum tied to shareholder count. Absent a contrary bylaw provision, directors are elected annually — Montana's Act is essentially a verbatim adoption of the current Revised Model Business Corporation Act, so staggered (classified) boards are permitted if the bylaws establish one, but that's not the default.

**Step 3 — Name your required officer positions.**

no specific named titles at all — §35-14-840 uses the modern, flexible approach: 'A corporation has the officers described in its bylaws or appointed by the board,' without requiring a 'president' or 'secretary' by name. Your bylaws simply need to describe whatever officer structure the corporation actually uses. Montana places no restriction on one person holding multiple officer titles simultaneously — a sole owner can hold every office the bylaws create, which is common for single-shareholder Montana corporations.

**Step 4 — Set meeting, notice, and quorum rules.**

Absent a contrary bylaw provision, Montana's default board quorum is a majority, but with a real floor: articles or bylaws may NOT set board quorum below one-third of the fixed or prescribed number of directors (§35-14-824) — a specific numeric limit that not every state imposes. The default shareholder quorum is a majority, adjustable by the articles (§35-14-725). Montana requires 10 to 60 days' notice of shareholder meetings absent a different bylaw provision (§35-14-705(1)). Board meeting notice is largely left to the bylaws to define.

**Step 5 — Address voting procedures.**

Montana's default voting standard for board and shareholder action is a majority of those present at a meeting where a quorum exists. Directors are elected by plurality by default (§35-14-728(1)). Montana is a clean baseline state on this point: cumulative voting requires an Articles opt-in only, with no automatic right whatsoever. §35-14-728(2) states plainly: 'Shareholders do not have a right to cumulate their votes for directors unless the articles of incorporation provide for that right.' Unlike Minnesota, North Dakota, Missouri, Nebraska, North Carolina, or Mississippi — all of which have some automatic or date-dependent cumulative-voting wrinkle — Montana simply requires the standard opt-in, making it one of this batch's genuinely 'textbook' states on this issue.

**Step 6 — Cover stock and shareholder mechanics.**

Montana permits both certificated and uncertificated shares under the standard modern Model Act mechanics — your bylaws should state which approach the corporation uses and how share records are maintained either way.

**Step 7 — Include an indemnification provision.**

Montana follows the standard modern two-tier pattern: permissive indemnification authority with defined exceptions (§35-14-851), but MANDATORY indemnification for a director who is 'wholly successful, on the merits or otherwise' in defending a claim (§35-14-852) — the same structure used by most of the modern Model Act states in this research batch.

**Step 8 — Write your amendment procedure.**

Under Montana law (§35-14-1020), the board may amend or repeal bylaws unless the articles or a shareholder-adopted bylaw reserves that power to shareholders — the standard modern Model Act default, with the board controlling amendment absent a specific reservation.

**Step 9 — Adopt the bylaws at your organizational meeting.**

Bylaws are typically adopted by the incorporator or the initial board of directors at the corporation's first organizational meeting, right after the Articles of Incorporation are filed. Adopting bylaws early — before you open a bank account or bring on your first shareholder — keeps your corporate formalities clean from day one, which matters if the corporation's liability shield is ever tested.

**Step 10 — Watch for Montana-specific bylaws traps.**

Montana is one of the 'cleanest' states in this research batch — a near-verbatim adoption of the modern Revised Model Business Corporation Act with no automatic cumulative voting, no unusual bylaw-amendment reversal, and no legacy grandfather clauses. The one number worth remembering is the one-third floor on board quorum (§35-14-824): your bylaws can raise board quorum above a majority, but can never drop it below one-third of the board.

## Frequently Asked Questions

### Does Montana require corporations to file bylaws with the state?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

No. Bylaws are an internal governance document under §35-14-206 — they're never filed with the Montana Secretary of State or any other agency. They stay with your corporate records rather than becoming part of the public record the way your Articles of Incorporation do.

### What's the difference between bylaws and Articles of Incorporation in Montana?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

Your Articles of Incorporation are a short public document filed with the Montana Secretary of State that creates the corporation's legal existence — name, registered agent, and authorized shares. Bylaws are a private, longer document that governs how the board, officers, and shareholders actually operate day to day, and they're never filed anywhere.

### What officer positions do Montana bylaws need to address?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

Montana doesn't require any specific named officer titles by statute (§35-14-840) — the corporation simply has whatever offices its bylaws describe or the board appoints. One person may hold every office the bylaws create.

### Can I amend my Montana corporation's bylaws later?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

Yes. Under Montana law, the board of directors can generally amend bylaws on its own unless the articles reserve that power to shareholders, or unless shareholders previously adopted a bylaw provision that only they can further amend. Your bylaws should include their own amendment procedure so it's clear from the start.

### What's the default quorum for board and shareholder meetings in Montana?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

Absent a contrary bylaw provision, Montana's default board quorum is a majority, but it can never be set below one-third of the board (§35-14-824). The default shareholder quorum is a majority, adjustable by the articles.

### Does Montana require corporations to indemnify their directors and officers?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

Montana's indemnification statute is permissive for most claims (§35-14-851) but becomes mandatory once a director is wholly successful in defending a claim on the merits or otherwise (§35-14-852) — the standard modern Model Act pattern.

### Can one person be the sole director, officer, and shareholder of a Montana corporation?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

Yes. Montana allows one person to be the sole shareholder, sole director, and hold every corporate officer title simultaneously — a common and fully valid structure for single-owner Montana corporations.

### Does Montana offer a simplified close corporation structure?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

No — Montana doesn't have a separate statutory close-corporation election. It instead relies on a modern Shareholder Agreements statute (§35-14-732) that lets shareholders eliminate the board and run the corporation directly by unanimous agreement, serving a similar function without a formal election.

### Does LLC Attorney draft bylaws for corporations?

![icon](/_next/image?url=%2Fimages%2Ficons%2FfaqPlus.png&w=128&q=75)

Yes. LLC Attorney drafts corporate bylaws tailored to your Montana corporation as part of formation, starting at $49.
