Shareholder Agreement

A contract among shareholders of a corporation that supplements the certificate of formation and bylaws by addressing matters such as voting, transfers, buy-sell rights, and dispute resolution.

A shareholder agreement is a contract among the shareholders of a corporation that supplements the certificate of formation and bylaws. Common provisions include voting agreements (requiring shareholders to vote together on specified matters), transfer restrictions (right of first refusal, drag-along, tag-along rights), buy-sell mechanics (mandatory purchase upon death, disability, departure, or dispute), valuation procedures (formula vs. appraisal), and dispute-resolution provisions (mediation, arbitration, forum-selection).

Shareholder agreements are particularly important in closely held corporations where the parties have negotiated for specific rights that go beyond the default rules of the corporate code. They also play a central role in family-business succession planning, where buy-sell mechanics determine how shares move between generations or branches of the family. In multi-owner businesses, well-drafted shareholder agreements are the most effective tool for preventing partner disputes from becoming litigation.

Permitted scope

For-profit corporations governed by the Texas Business Organizations Code may enter into shareholder agreements that vary the default rules under § 21.101, subject to certain limits. Shareholder agreements may, among other things, eliminate or limit the powers of the board, govern distributions, restrict transfers, require specified buy-sell mechanics, and authorize binding dispute resolution.

Recent developments

Senate Bill 29 (effective May 14, 2025) authorized shareholder agreements to include jury waivers and exclusive forum-selection clauses for internal entity claims (TBOC §§ 2.115 and 2.116). The codified business judgment rule in § 21.419 also interacts with shareholder agreement provisions allocating director protection.
