Drafting and negotiation of shareholders agreements in Chile by Anguita Osorio.
Transfer restrictions, tag along, drag along, deadlock and exit mechanics for SpA and corporations.
Shareholders agreements: what they regulate and when to sign one
The bylaws create the company; the shareholders agreement governs the relationship among its owners. It decides who can sell and to whom, who controls the board, what happens when the partners disagree and how someone leaves. Every rule it omits gets negotiated later, in the middle of the conflict it was supposed to prevent.

This page covers what a shareholders agreement is and how it relates to the bylaws, the clauses that do the real work (transfer, governance, deadlock, exit), how registration makes it effective against third parties, and the drafting errors that turn it into paper. It applies to the SpA and the sociedad anónima alike; the differences are noted where they matter.
Bylaws and agreement: two instruments, two jobs
The bylaws are the company's public constitution: they bind every shareholder, present and future, and are amended by shareholder meeting. The agreement is a private contract: it binds only its signatories, is amended by their unanimity and can regulate what the bylaws cannot or should not show. Exit prices, non-compete undertakings, founder vesting and investor vetoes belong in the agreement; share series, quorums and corporate purpose belong in the bylaws.
In the SpA the boundary is more flexible: article 424 of the Commercial Code gives its bylaws near-total freedom, so many rules can live in either instrument. The choice is then strategic, not legal: what goes in the bylaws is public and binds everyone; what goes in the agreement stays private and binds the signatories.
The clauses that do the work
Four families of rules answer the four conflicts every multi-partner company eventually faces.
Who can sell, and to whom
Right of first offer or first refusal before selling to a third party, lock-up periods, and permitted transfers (family vehicles, affiliates). The goal: no partner wakes up with a stranger at the table.
Tag along and drag along
Tag along lets minority partners join a sale by the majority on the same terms; drag along lets the majority compel everyone to sell when a buyer wants 100%. Together they make the company sellable.
Board, vetoes and information
Who appoints how many directors, which decisions need a qualified majority or investor consent (debt, related-party deals, new shares), and what information each partner receives and when.
What happens when partners disagree
Escalation mechanisms, buy-sell options (including shotgun clauses), put and call options with a valuation formula, and arbitration. The exit rule is the one clause everyone hopes never to use and no one should sign without.
Registration: making it work against third parties
Between its signatories the agreement binds from signature. Against third parties, article 14 of Law 18.046 sets the rule for corporations: share-transfer agreements must be deposited with the company and their existence noted in the Shareholders Registry; unregistered agreements cannot be asserted against third parties. The SpA follows the same logic through the supplementary application of the corporations regime. The practical consequence: an unregistered transfer restriction does not stop a sale to a third party; it only supports a damages claim against the seller.
The errors that turn an agreement into paper
- Copying a foreign template: preferences and mechanics designed for Delaware often collide with Chilean corporate and tax rules, and some are simply unenforceable here.
- Exit clauses without a valuation formula: an option "at market price" with no method to set that price is an invitation to litigate.
- Obligations without remedies: undertakings with no penalty clause, no exercisable option and no arbitration seat convert breach into a cheap decision.
- Forgetting the registry: leaving the agreement out of the Shareholders Registry, which leaves it unenforceable exactly when a third party appears.
- Not updating it: agreements signed at incorporation rarely survive a financing round or a partner change without amendment.
The agreement rarely lives alone: in an acquisition it interacts with the legal due diligence and the purchase agreement, and in a financing round with the investment documents. The criminal-liability side of M&A has its own page: successor liability under Law 20.393.
Frequently asked questions
What is a shareholders agreement?
A contract among all or some shareholders of a company regulating matters the bylaws do not cover or that are better kept out of them: how shares are transferred, how certain decisions are made, what happens when a partner wants to exit and how deadlocks are resolved. It binds only its signatories, unlike bylaws, which bind every present and future shareholder.
Is a shareholders agreement mandatory in Chile?
No. No statute requires one. It is a voluntary tool, but in practice no serious investor joins a multi-partner company without one: template bylaws do not solve partner exit, joint sale or deadlock, and renegotiating those rules in the middle of a conflict is far more expensive than agreeing them at the start.
How does it differ from the bylaws?
Bylaws are public, bind all shareholders and are amended by shareholder meeting under statutory majorities. The agreement is a private contract binding only its signatories and amended by their unanimity. Sensitive rules (exit price, non-compete, founder vesting) usually go in the agreement; structural rules (share series, quorums) in the bylaws. In the SpA the line is more flexible, since its bylaws admit almost anything, but the logic of what to keep private holds.
Is the agreement enforceable against third parties?
It depends on registration. For corporations, Article 14 of Law 18.046 requires depositing share-transfer agreements with the company and noting their existence in the Shareholders Registry; otherwise they cannot be asserted against third parties. The same logic applies to the SpA through the supplementary regime. An unregistered agreement still binds its signatories, but does not prevent a third party from acquiring shares free of it.
Which clauses should a shareholders agreement include?
The ones that answer that company's probable conflicts, not a template. The usual core: transfer restrictions (right of first offer or first refusal), joint-sale mechanics (tag along and drag along), governance (board composition, veto matters, information rights), deadlock mechanisms and exit rules (put and call options, valuation). In startups, founder vesting, non-compete and investor preferences are added.
What happens if a shareholder breaches the agreement?
It is enforced like any contract: damages and, where the drafting allows, specific performance of the agreed obligation. Drafting quality decides the outcome: penalty clauses with defined amounts, exercisable call options and well-designed arbitration make the agreement enforceable; a statement of intentions without enforcement mechanics does not.
