Frequently Asked Questions (FAQs)<\/a><\/li>\n<\/ol>\n<\/nav>\n<p style=\"margin:0 0 16px;\">Many Spanish companies, especially limited companies with two or three shareholders and startups in their early funding rounds, are incorporated without a shareholders agreement. The assumption is that &#8220;we understand each other&#8221; and that the bylaws already cover the essentials. That is not the case: bylaws are a public document, aimed at third parties, with a minimum and fairly rigid content that does not get into the nuances of the relationship between shareholders.<\/p>\n<p style=\"margin:0 0 16px;\">The risk of not having a shareholders agreement, or of having a poorly drafted one, tends to surface at the worst possible moment: when the company starts generating real value, when an investor comes in, or when a shareholder decides to leave. At that point, with no rules agreed in advance, the dispute moves to the courts, with costs in time and money that almost always exceed what it would have cost to draft a proper agreement from the outset.<\/p>\n<p style=\"margin:0 0 16px;\">This guide explains what a shareholders agreement is, how it differs from the bylaws, which clauses tend to make the difference between an agreement that genuinely protects shareholders and one that ends up in a drawer, and when it is worth reviewing or updating it. It applies both to traditional limited companies and to startups going through funding rounds, and to family businesses working through succession.<\/p>\n<p style=\"margin:0 0 28px;\">We also go through the most common drafting mistakes, because they tend to be the same ones: using a generic template, leaving a 50\/50 deadlock unresolved, or failing to update the agreement when the company&#8217;s circumstances change.<\/p>\n<h2 id=\"what-is-shareholders-agreement\" style=\"margin:clamp(48px,9vw,68px) 0 20px;padding-top:20px;border-top:1px solid #000;color:#000;font-family:PlayfairDisplay,Georgia,serif;font-size:clamp(27px,5.8vw,42px);line-height:1.04;font-weight:600;\">What a shareholders agreement is and what it&#8217;s for<\/h2>\n<p style=\"margin:0 0 16px;\">A <strong style=\"color:#000;font-weight:800;\">shareholders agreement<\/strong> is a private contract between a company&#8217;s shareholders that governs how they will relate to one another beyond what the bylaws say: how important decisions are made, what happens if one shareholder wants to sell their stake, what happens if two 50\/50 shareholders cannot agree, or what conditions apply to a founder&#8217;s shares if they leave the project early.<\/p>\n<p style=\"margin:0 0 16px;\">In essence, it exists to set out in writing, ahead of time, the scenarios that most often generate conflict between shareholders: the entry of new investors, a founder&#8217;s departure, the balance of decision-making power, or the sale of the company. It typically includes, among other elements:<\/p>\n<ul style=\"margin:0 0 16px 22px;padding:0;\">\n<li style=\"margin:0 0 7px;\"><strong style=\"color:#000;font-weight:800;\">Majority rules<\/strong> for strategic decisions.<\/li>\n<li style=\"margin:0 0 7px;\"><strong style=\"color:#000;font-weight:800;\">Transfer rules<\/strong> for shares, both between shareholders and towards third parties.<\/li>\n<li style=\"margin:0 0 7px;\"><strong style=\"color:#000;font-weight:800;\">Orderly exit mechanisms<\/strong> for founders and investors.<\/li>\n<li style=\"margin:0 0 7px;\"><strong style=\"color:#000;font-weight:800;\">Protective clauses<\/strong> such as non-compete or confidentiality provisions.<\/li>\n<\/ul>\n<p style=\"margin:0 0 16px;\">A good shareholders agreement does not repeat what the bylaws already say: it complements them, covering everything the bylaws cannot or should not include. The freedom to enter into these agreements stems from the principle of freedom of contract set out in <a style=\"color:#000;font-weight:700;text-decoration:underline;text-decoration-color:#797979;text-underline-offset:4px;\" href=\"https:\/\/www.boe.es\/buscar\/act.php?id=BOE-A-1889-4763\" target=\"_blank\" rel=\"noopener\">article 1255 of the Spanish Civil Code<\/a>, which allows parties to agree whatever they consider appropriate, provided it is not contrary to law, morality or public policy.<\/p>\n<h2 id=\"agreement-vs-bylaws\" style=\"margin:clamp(48px,9vw,68px) 0 20px;padding-top:20px;border-top:1px solid #000;color:#000;font-family:PlayfairDisplay,Georgia,serif;font-size:clamp(27px,5.8vw,42px);line-height:1.04;font-weight:600;\">Shareholders agreement vs. articles of association: which prevails and why<\/h2>\n<p style=\"margin:0 0 16px;\">The first common mistake is confusing the two documents. <strong style=\"color:#000;font-weight:800;\">Company bylaws<\/strong> (the articles of association) are public, are registered with the <strong style=\"color:#000;font-weight:800;\">Commercial Registry<\/strong>, and are enforceable against third parties. A <strong style=\"color:#000;font-weight:800;\">shareholders agreement<\/strong>, by contrast, is a private contract that only binds those who sign it: it is not registered, is not public, and can cover matters shareholders would rather not disclose (for example, the economic terms of an exit or financing arrangements).<\/p>\n<p style=\"margin:0 0 16px;\">This private nature has an important legal consequence: if the agreement and the bylaws contradict each other, the bylaws prevail against a third party acting in good faith. Between the shareholders themselves, however, the agreement is fully enforceable and a breach can be claimed in court, including damages or agreed penalties.<\/p>\n<p style=\"margin:0 0 16px;\">That is why it matters for both documents to be well coordinated: what is essential for third parties should be in the bylaws, and what governs the internal relationship between shareholders belongs in the agreement. Without an agreement, many important decisions can be approved with the ordinary majority set out in the <strong style=\"color:#000;font-weight:800;\">Spanish Companies Act<\/strong>, which gives enormous power to any shareholder or block that controls just over 50% of the company.<\/p>\n<h2 id=\"essential-clauses\" style=\"margin:clamp(48px,9vw,68px) 0 20px;padding-top:20px;border-top:1px solid #000;color:#000;font-family:PlayfairDisplay,Georgia,serif;font-size:clamp(27px,5.8vw,42px);line-height:1.04;font-weight:600;\">Clauses that shouldn&#8217;t be missing<\/h2>\n<p style=\"margin:0 0 16px;\">Not every company needs the same clauses, but in our experience there is a core set that makes the difference between a shareholders agreement that genuinely protects the company and one that ends up in a drawer, never actually doing its job.<\/p>\n<h3 style=\"margin:30px 0 12px;color:#000;font-family:Raleway,Arial,sans-serif;font-size:clamp(18px,4.6vw,22px);line-height:1.25;font-weight:800;\">Enhanced majorities for key decisions<\/h3>\n<p style=\"margin:0 0 16px;\">A well-designed shareholders agreement raises the approval threshold for especially sensitive decisions: borrowing above a set amount, disposing of essential assets, admitting new shareholders, amending the bylaws, or distributing dividends. The practical recommendation is to list, in a closed way, which matters require an enhanced majority (for example, 75% or 80%) and which follow the ordinary regime. An open or vague list generates disputes about its own interpretation \u2014 exactly what the agreement should be preventing.<\/p>\n<h3 style=\"margin:30px 0 12px;color:#000;font-family:Raleway,Arial,sans-serif;font-size:clamp(18px,4.6vw,22px);line-height:1.25;font-weight:800;\">Right of first refusal on share transfers<\/h3>\n<p style=\"margin:0 0 16px;\">A <strong style=\"color:#000;font-weight:800;\">right of first refusal<\/strong> gives existing shareholders preference to buy shares that another shareholder wants to sell, before they can pass to an outside third party. It is worth setting a precise deadline to exercise it, a reference price (an agreed valuation, an independent valuer, or the same price offered by the third party), and what happens if several shareholders want to exercise it at the same time. Without this clause, any shareholder can sell their stake to a stranger with no chance for the rest to react.<\/p>\n<h3 style=\"margin:30px 0 12px;color:#000;font-family:Raleway,Arial,sans-serif;font-size:clamp(18px,4.6vw,22px);line-height:1.25;font-weight:800;\">Drag-along and tag-along<\/h3>\n<p style=\"margin:0 0 16px;\">A <strong style=\"color:#000;font-weight:800;\">drag-along clause<\/strong> allows the majority shareholders (or an agreed percentage) to force minority shareholders to sell their shares on the same terms if they decide to sell the company to a third party. This is especially relevant for startups, where an investor buying 100% of the capital is usually unwilling to be left with a minority shareholder who refuses to exit. The important legal nuance here is that drag-along must come with fair-price guarantees: it is normally required that the terms offered to minority shareholders be at least equivalent to those offered to the shareholder driving the sale.<\/p>\n<p style=\"margin:0 0 16px;\">The counterpart is <strong style=\"color:#000;font-weight:800;\">tag-along<\/strong>, or the right to join a sale: if the majority shareholder sells their stake, minority shareholders have the right to sell theirs on the same terms, rather than being left as shareholders of a new controlling party they did not choose. It is worth checking that the agreement clearly defines what &#8220;the same terms&#8221; means (price, form of payment, timelines), so the right is effective rather than merely theoretical.<\/p>\n<div style=\"margin:24px 0;overflow-x:auto;\">\n<table style=\"width:100%;min-width:640px;border-collapse:collapse;border-top:1px solid #000;border-bottom:1px solid #000;font-size:15px;line-height:1.55;\">\n<thead>\n<tr>\n<th style=\"padding:13px 12px;text-align:left;border-bottom:1px solid #000;color:#000;font-weight:800;\">Clause<\/th>\n<th style=\"padding:13px 12px;text-align:left;border-bottom:1px solid #000;color:#000;font-weight:800;\">Mainly protects<\/th>\n<th style=\"padding:13px 12px;text-align:left;border-bottom:1px solid #000;color:#000;font-weight:800;\">Risk if not agreed<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">Right of first refusal<\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">Existing shareholders against outside third parties.<\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">An unwanted shareholder joins the company with no way to react.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">Drag-along<\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">The buyer and the majority shareholders.<\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">A minority shareholder blocks the sale of the whole company.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">Tag-along<\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">Minority shareholders.<\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">Being stuck with a new controlling shareholder you did not choose.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\"><strong style=\"color:#000;font-weight:800;\">Deadlock mechanism<\/strong><\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">The continuity of a 50\/50 company.<\/td>\n<td style=\"padding:12px;border-bottom:1px solid #e6e6e6;\">Total paralysis on any strategic decision.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding:12px;\">Good leaver \/ bad leaver<\/td>\n<td style=\"padding:12px;\">The shareholders who remain in the project.<\/td>\n<td style=\"padding:12px;\">A founder leaves early while keeping capital they did not earn.<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/div>\n<h3 style=\"margin:30px 0 12px;color:#000;font-family:Raleway,Arial,sans-serif;font-size:clamp(18px,4.6vw,22px);line-height:1.25;font-weight:800;\">Non-compete and confidentiality<\/h3>\n<p style=\"margin:0 0 16px;\">A shareholder who leaves and starts an identical business the next day, using the company&#8217;s client base, know-how or contacts, can cause considerable damage. <strong style=\"color:#000;font-weight:800;\">Non-compete clauses<\/strong> limit this for a reasonable period after departure (typically one to two years, with a clearly defined geographic and material scope so the clause is valid and proportionate), while <strong style=\"color:#000;font-weight:800;\">confidentiality clauses<\/strong> protect the company&#8217;s sensitive information, both during the relationship and after it ends. It is advisable to pair these clauses with a specific financial penalty for breach, because without one, a court claim tends to be slow and uncertain in outcome.<\/p>\n<h3 style=\"margin:30px 0 12px;color:#000;font-family:Raleway,Arial,sans-serif;font-size:clamp(18px,4.6vw,22px);line-height:1.25;font-weight:800;\">Resolving deadlocks<\/h3>\n<p style=\"margin:0 0 16px;\">In companies with two 50\/50 shareholders, or two balanced blocks, the risk of a <strong style=\"color:#000;font-weight:800;\">deadlock<\/strong> is very high: it only takes one strategic disagreement to bring the company to a standstill. A good agreement anticipates this scenario with concrete mechanisms: mandatory prior mediation, a cross buy-sell option (one shareholder offers to buy or sell at a price they set), arbitration, or even agreed dissolution if the deadlock continues beyond a set period. Leaving this issue unaddressed is one of the most frequent causes of shareholder litigation once a company grows and decisions stop being trivial.<\/p>\n<h3 style=\"margin:30px 0 12px;color:#000;font-family:Raleway,Arial,sans-serif;font-size:clamp(18px,4.6vw,22px);line-height:1.25;font-weight:800;\">Shareholder exits: good leaver \/ bad leaver, vesting and liquidation preference<\/h3>\n<p style=\"margin:0 0 16px;\"><strong style=\"color:#000;font-weight:800;\">Good leaver \/ bad leaver<\/strong> clauses determine the economic terms a founding shareholder receives when leaving the company, depending on the circumstances of their departure. A &#8220;good leaver&#8221; (for example, someone who leaves for justified reasons: illness, retirement, mutual agreement) usually keeps the market value of their shares. A &#8220;bad leaver&#8221; (someone who breaches their obligations, leaves without justification within a short period, or competes unfairly) may see that value reduced, sometimes down to nominal value. This distinction is decisive for startups, where several founders dedicate time and effort from day one: without this clause, someone could leave after a few months while keeping a significant percentage of the capital without having put in the expected work.<\/p>\n<p style=\"margin:0 0 16px;\"><strong style=\"color:#000;font-weight:800;\">Vesting<\/strong> consolidates founders&#8217; ownership of their shares progressively over a period (typically three to four years), rather than handing them over in full from incorporation. It is a standard practice in the startup ecosystem and one of the clauses investors demand most before joining a round. It is usually combined with an initial <strong style=\"color:#000;font-weight:800;\">cliff<\/strong> period (normally one year) during which no shares vest at all if the founder leaves early, after which the rest vests monthly or quarterly.<\/p>\n<p style=\"margin:0 0 16px;\"><strong style=\"color:#000;font-weight:800;\">Liquidation preference<\/strong> is a common clause when an outside investor joins: it guarantees they will recover their investment (or a multiple of it) before other shareholders receive any distribution, in the event of a sale or liquidation of the company. It is reasonable for an investor to require it, but its scope should be negotiated carefully: a simple preference (which also participates in the remaining distribution) is not the same as full-participation preference, which can leave founders with very little in modest exit scenarios.

Unlike the bylaws, it is not registered with the Commercial Registry and only binds those who sign it. It is enforceable between shareholders, although the bylaws prevail against a third party acting in good faith in case of contradiction. It is drafted under the freedom-of-contract principle set out in article 1255 of the Spanish Civil Code.<\/p>\n<\/details>\n<details style=\"border-bottom:1px solid #e6e6e6;padding:0;\">\n<summary style=\"cursor:pointer;display:flex;align-items:center;justify-content:space-between;gap:16px;padding:18px 0;color:#000;font-weight:800;list-style:none;\">Is a shareholders agreement mandatory?<span style=\"display:inline-flex;align-items:center;justify-content:center;min-width:26px;height:26px;border:1px solid #000;font-weight:800;\">+<\/span><\/summary>\n<p style=\"margin:0 0 18px;\">No, the law does not require it. A company can be validly incorporated and operate with only its bylaws. In practice, however, it is highly recommended, especially when there is more than one shareholder with a significant stake, when there is a risk of a 50\/50 deadlock, or when outside investors join and will require specific clauses (vesting, liquidation preference) that do not naturally fit into standard bylaws. The absence of an agreement carries no legal penalty, but it does leave the company without tools to resolve future conflicts.<\/p>\n<\/details>\n<details style=\"border-bottom:1px solid #e6e6e6;padding:0;\">\n<summary style=\"cursor:pointer;display:flex;align-items:center;justify-content:space-between;gap:16px;padding:18px 0;color:#000;font-weight:800;list-style:none;\">Is there a shareholders agreement template that works for any company?<span style=\"display:inline-flex;align-items:center;justify-content:center;min-width:26px;height:26px;border:1px solid #000;font-weight:800;\">+<\/span><\/summary>\n<p style=\"margin:0 0 18px;\">Not reliably.

That is why it is important for both documents to be well coordinated: what matters to third parties should be in the bylaws, and what governs the internal relationship between shareholders, in the agreement.<\/p>\n<\/details>\n<details style=\"border-bottom:1px solid #e6e6e6;padding:0;\">\n<summary style=\"cursor:pointer;display:flex;align-items:center;justify-content:space-between;gap:16px;padding:18px 0;color:#000;font-weight:800;list-style:none;\">When should a startup sign a shareholders agreement?<span style=\"display:inline-flex;align-items:center;justify-content:center;min-width:26px;height:26px;border:1px solid #000;font-weight:800;\">+<\/span><\/summary>\n<p style=\"margin:0 0 18px;\">Ideally from incorporation, before any tension between founders exists, including vesting and exit-regime clauses from the start. In any case, it is essential before closing an investment round, since investors will require clauses such as liquidation preference, drag-along or tag-along as a condition for joining. Drafting the agreement under pressure, in the middle of a funding negotiation, tends to produce worse results than doing it calmly in an early phase of the project.<\/p>\n<\/details>\n<details style=\"border-bottom:1px solid #e6e6e6;padding:0;\">\n<summary style=\"cursor:pointer;display:flex;align-items:center;justify-content:space-between;gap:16px;padding:18px 0;color:#000;font-weight:800;list-style:none;\">How much does it cost to draft a shareholders agreement with a lawyer?<span style=\"display:inline-flex;align-items:center;justify-content:center;min-width:26px;height:26px;border:1px solid #000;font-weight:800;\">+<\/span><\/summary>\n<p style=\"margin:0 0 18px;\">The cost depends on the complexity of the company: number of shareholders, presence of investors, sector of activity, and the specific clauses required. A simple agreement between two or three founding shareholders costs less than one that must integrate liquidation preference, staged vesting and drag-along provisions for an investment round. In any case, the cost of drafting it properly from the start is significantly lower than that of shareholder litigation resulting from not having one, or from having a poorly drafted one.<\/p>\n<\/details>\n<details style=\"border-bottom:1px solid #e6e6e6;padding:0;\">\n<summary style=\"cursor:pointer;display:flex;align-items:center;justify-content:space-between;gap:16px;padding:18px 0;color:#000;font-weight:800;list-style:none;\">Can a shareholders agreement be amended once signed?<span style=\"display:inline-flex;align-items:center;justify-content:center;min-width:26px;height:26px;border:1px solid #000;font-weight:800;\">+<\/span><\/summary>\n<p style=\"margin:0 0 18px;\">Yes. Being a private contract, it can be amended at any time if all signing shareholders agree, following whatever amendment procedure the agreement itself sets out (usually unanimity or a specific enhanced majority for this purpose).
