Corporate Shareholder Agreement Governance-Override Requirements in Texas

At a glance

Requirements one by one

Agreement subjects and corporation-binding effect

Texas supplies a detailed subject menu. The agreement may restrict or eliminate the board, place management in shareholders or other persons, establish directors or officers, govern employment, distributions, profit and loss, voting, property or services, arbitration or deadlock authority, winding up, social purposes, and other governance relationships not contrary to public policy (Tex. Bus. Orgs. Code § 21.101(a)).

If the agreement complies with the subchapter, it is effective among the shareholders and between them and the corporation even when its terms are inconsistent with the Business Organizations Code (Tex. Bus. Orgs. Code § 21.104).

Initial adoption and amendment

The certificate-of-formation or bylaw route requires approval by all shareholders at the time of the agreement. The separate-writing route requires every current shareholder's signature and that the agreement be made known to the corporation. Amendment likewise defaults to all shareholders at the time of amendment, but the agreement may provide another rule (Tex. Bus. Orgs. Code § 21.101(b)).

If no shares have been issued when the agreement is signed, an organizer or a subscriber for shares may act as a shareholder for this purpose (Tex. Bus. Orgs. Code § 21.108).

Duration and public-market termination

For a current agreement, any term limit must be in the agreement itself. The ten-year rule is a legacy clause only: an agreement already in effect before September 1, 2015 remains effective for ten years unless it provides otherwise (Tex. Bus. Orgs. Code § 21.102).

The statutory agreement ceases to be effective when the corporation's shares are listed on a national securities exchange or regularly traded in a market maintained by members of a national or affiliated securities association. If the agreement had eliminated the board, the board must be instituted or reinstated; a board may also remove the expired agreement from the certificate or bylaws without shareholder action (Tex. Bus. Orgs. Code § 21.109).

Disclosure, purchaser rescission, and liability

The certificate or uncertificated-share information statement must conspicuously carry the exact warning prescribed by Section 21.103. A corporation with outstanding certificates must recall them and issue compliant substitutes. Omission does not invalidate the agreement or corporate action, but a purchaser who lacked knowledge at purchase may rescind within the earlier of 90 days after discovery or two years after purchase (Tex. Bus. Orgs. Code §§ 21.103, 21.105).

When the agreement shifts board discretion or management, the directors are relieved and the person receiving that power assumes director-law liability in the same manner and to the same extent. The agreement, partnership-like or tax treatment, and failure to observe covered formalities are not by themselves grounds to impose personal liability on a shareholder for corporate obligations (Tex. Bus. Orgs. Code §§ 21.106-.107).

What trips people up

The notice rule has two different consequences. Missing the certificate or information-statement notation does not affect agreement validity under Section 21.103(d), but the rescission provision protects a purchaser who lacked knowledge. For uncertificated shares, deemed knowledge also requires delivery of the information statement no later than the purchase time (Tex. Bus. Orgs. Code § 21.105).

Texas also maintains a separate statutory-close-corporation framework later in Chapter 21. This page addresses the general Subchapter C agreement available to a domestic for-profit corporation; it does not import the close-corporation provisions, certificate language, judicial remedies, or management rules into the ordinary route.

Common questions

Must the corporation itself sign the Texas agreement?

Section 21.101(b) does not state a corporation-signature requirement. It uses either a certificate or bylaw approved by all current shareholders, or a writing signed by all current shareholders and made known to the corporation. Other contract and authorization issues remain document-specific.

Is every Texas shareholder agreement limited to ten years?

No. Section 21.102 says a current term limit must appear in the agreement. Its ten-year language applies to agreements that were already in effect before September 1, 2015, unless those agreements provide otherwise.

Can the agreement remain effective after the corporation becomes publicly traded?

Not under this subchapter once the shares are nationally listed or regularly traded in the market described by Section 21.109(a). The provision also requires a board to be instituted or reinstated when the corporation had none.
