Most family businesses in Spain do not have a family business protocol, and many that do wrote it once and never revisited it. The problem does not usually show up in day-to-day management, but at moments of change: the second or third generation joining, the founder’s death or retirement, or a son-in-law, daughter-in-law or outside capital partner entering the business. That is when the lack of written rules becomes a real conflict, with both financial and personal consequences.
The risk is not just disagreement among family members. It is a deadlock from a tied vote, paralysis in decision-making, ownership becoming diluted among heirs who do not share a common view on management, or poorly planned succession that spikes the tax bill exactly when the company needs cash flow to keep operating. Family businesses have a particularly high failure rate at the jump from the second to the third generation, and in most cases it is not for lack of business, but for lack of clear rules among people who are, at once, family and shareholders.
This guide explains exactly what a family business is, what the family protocol should include as the central tool for organising the relationship between family, ownership and management, how it connects with succession planning and taxation, what risks a company without one is running, and which other documents need to accompany it for it to have real effect.
What a family business protocol is and why it matters
The family business protocol is the document that governs the relationship between family, ownership and the management of the business: it sets who can work in the company and under what requirements, how dividends are distributed, how conflicts between family shareholders are resolved, which governance bodies exist, and how succession is planned. Its function is not decorative: it anticipates, with written rules agreed calmly in advance, the conflicts that almost always appear at moments of change.
To know what that protocol needs, it helps to start by defining, in your case, what a family business actually is. There is no single legal definition, but the most widely accepted criterion combines two elements: control of ownership (a majority of the capital or voting rights held by a family) and the intention of generational continuity, meaning the aim for the next generation to keep running the business, or at least remain its owner. According to the figures usually published by the Instituto de la Empresa Familiar, this type of business makes up the majority of Spain’s corporate fabric and a very significant share of private-sector employment.
This is not a theoretical exercise: it determines which clauses your protocol needs. A first-generation family business, with the founder still at the helm and a single family branch, is not the same as a third-generation business with several branches, cousins who barely know each other, and already-separate estates. The design of the protocol depends directly on where your company sits along that path, and that is what the rest of this guide covers.
What a family business protocol should include
A complete family business protocol does not stop at declaring good intentions: it regulates, in concrete terms, the governance of the company, the admission of new generations, the exit of shareholders and the dividend policy. These are the blocks it should not be missing.
Family members joining and leaving the business
One of the most sensitive parts of a family protocol is the admission policy: what requirements a family member must meet to work in the business (minimum qualifications, prior experience outside the family firm, a selection process comparable to that of any external candidate), and under what conditions they can access a management position. It must also govern exit: how a family shareholder’s stake is valued when they want to sell, using what valuation method, and on what payment schedule to avoid straining the company’s cash flow. Without these rules in writing, every admission or exit is negotiated from scratch, usually at a moment of family tension, which worsens the terms for everyone involved.
Dividends and remuneration: separating being a shareholder from working in the business
One of the most common mistakes is confusing the status of shareholder with that of employee or executive. The protocol should set a clear dividend policy (what percentage of profit is distributed and what is reinvested) and, separately, a remuneration criterion for family members who work in the business, based on the role and the market rate, not on kinship. This separation also matters for tax purposes: to apply the benefits under Spain’s Inheritance and Gift Tax, family members with management duties are typically required to receive remuneration above a certain threshold relative to their other income, as required by Spain’s Wealth Tax rules.
Governance bodies: family council and board of directors
A mature family protocol distinguishes two bodies with different functions. The board of directors, governed by the Spanish Companies Act, is the corporate management body and must operate on professional criteria, regardless of who is or is not family. The family council, by contrast, is the forum where the family discusses matters that are not strictly corporate: values, criteria for bringing in new generations, resolving internal disputes. Keeping the two spaces separate stops family discussions from contaminating business management, and vice versa. You can see how this dual governance model for family businesses works in practice.
Family business protocol and succession: tax rules and the 95% reduction
Family business succession should not be decided in the months following the founder’s death, but designed years in advance. This means identifying whether there is a clear successor for management, whether ownership will be split equally among heirs or whether compensation mechanisms are planned for those who do not join the business, and what happens if no heir wants or is able to take over management. Well-planned succession separates ownership of the shares from the ability to manage — a distinction many families do not make until it is too late.
Family businesses also benefit from favourable tax treatment on generational transfers. Article 20 of Spain’s Inheritance and Gift Tax rules allows a 95% reduction in the taxable base on the transfer of shares in a family business, provided the exemption requirements set out in the Wealth Tax Act are met: a minimum shareholding percentage (individual or across the family group), remunerated management functions above a certain income threshold, and holding the acquired shares for several years after the transfer. Meeting these requirements is not automatic: it depends on how ownership is structured and how the succession is documented, so it is worth reviewing well in advance rather than at the moment the tax is settled.
Risks of not having a family business protocol
Without a protocol, the rules of the family business get improvised once it is already too late. The most frequent conflicts we see are:
- Deadlock from a tied vote between family branches holding the same percentage of capital.
- In-laws joining management (sons-in-law, daughters-in-law, partners) with no prior criteria.
- Lack of a clear plan for when the founder dies or becomes incapacitated.
- Gradual dilution of ownership among heirs who do not agree on how to manage the business together.
None of these risks are solved with good will alone. They are solved with a document that anticipates the conflict before it happens, and with the right governance bodies to apply it when the moment comes.
How a family business protocol is designed
By nature, a family protocol reflects family agreements, but it does not always carry the same legal force on its own as a contract or registered bylaws. Designing it well means accompanying it with a layer of complementary legal documents and instruments that make it genuinely binding and enforceable against third parties.
| Document or body | What it governs | Risk if missing |
|---|---|---|
| Family protocol | Values, admission, exit, dividends and governance bodies. | Every decision gets improvised in a moment of tension. |
| Family council | Forum for family values and criteria, with no direct corporate effect. | Family conflicts spill over into the running of the business. |
| Board of directors | Corporate management on professional criteria. | Business decisions taken with no independent professional judgement. |
| Shareholders agreement | Turns the family’s agreements into enforceable commitments among signatories. | The protocol remains a mere statement of intent. |
| Will | Carries the protocol’s intentions into the inheritance itself. | Succession disconnected from what was agreed during the founder’s lifetime. |
For it to be genuinely effective, the design should include: a shareholders agreement that turns the protocol’s rules into commitments enforceable among the signatories, bylaws adapted under the Spanish Companies Act, and a will (and, where the applicable civil law allows, such as in some Spanish regions, marriage settlements or succession agreements) that ensures the protocol’s intentions are also honoured at inheritance level. Without this layer of legal instruments, the family protocol risks remaining a mere statement of intent.
The family protocol also does not replace the contracts that govern executives’ relationship with the company. If your family business has executives on senior management contracts, it is also worth reviewing how that special employment relationship is protected — something we cover in more detail in our article on senior executive contract severance protection. This type of contract usually affects precisely the family members who have already joined executive management, so both documents — the protocol and the senior management contract — need to be consistent with each other.
Finally, a family protocol drafted fifteen years ago, designed for two founding shareholders, rarely serves a third generation with six cousins and already-separate estates. Every time a new generation joins, the corporate structure changes significantly, or tax or corporate regulations are updated, is a good moment to review the document. A protocol that is never updated stops fulfilling its preventive purpose exactly when it is needed most.
How GraciaCalbet can help you
At GraciaCalbet we have spent more than 45 years supporting family businesses in Barcelona and Madrid, both in drafting the family protocol and in designing the full succession plan. We know every family business is different: designing a protocol for a first generation is not the same as organising succession among several family branches in a third generation.
We work on the family protocol, the shareholders agreement, the bylaws, the family council and board of directors, and the tax planning for the transfer, all together, so that the rules agreed have real effect rather than staying on paper. If your family business still does not have a protocol, or the one it has no longer reflects the current reality of the family and the business, you can find out how we work on family business protocol at GraciaCalbet and start with a review of your specific situation.
Frequently Asked Questions (FAQs)
What exactly is a family business protocol?+
It is the document that governs the relationship between family, ownership and the business: who can work in the company and under what requirements, how dividends are distributed, how conflicts between family shareholders are resolved, which governance bodies exist (family council and board of directors), and how succession is planned. It does not always have full legal effect against third parties on its own, so it is complemented by a shareholders agreement, bylaws and a will. Its purpose is to anticipate the typical conflicts of a family business before they occur, especially at moments of generational change.
Is a family business protocol mandatory?+
No, the law does not require family businesses to have a protocol. It is a voluntary instrument, though highly recommended once there is more than one family shareholder or a new generation is expected to join. The absence of a protocol carries no legal penalty, but it does significantly raise the risk of conflict, corporate deadlock or improvisation during succession when a major change arrives, such as the founder’s death or retirement.
What is the difference between a family protocol and a shareholders agreement?+
The family protocol sets out broad family agreements on values, admitting new generations, and family governance bodies. The shareholders agreement, on the other hand, translates some of those agreements into legally enforceable commitments among the signing shareholders, with clear consequences for breach. Ideally, and recommendably, both documents coexist: the protocol sets the framework for family relations, and the shareholders agreement gives contractual force to the more sensitive corporate matters, consistent with the Spanish Companies Act.
How is family business succession planned?+
Succession is planned by identifying in advance who will take on management (which does not always match who inherits ownership), how capital will be split among heirs, and what compensation mechanisms exist for family members who do not join the business. It is also worth reviewing the tax requirements to benefit from the reduction in Inheritance and Gift Tax, and coordinating the protocol with the will and, where relevant, succession agreements. The earlier it is planned, the lower the risk of improvised decisions following a death or incapacity.
What tax advantages does transferring a family business have?+
The rules allow a 95% reduction in the taxable base of Inheritance and Gift Tax for the transfer of shares in a family business, provided the exemption requirements under Wealth Tax are met: a minimum shareholding percentage held by the family group, remunerated management functions above a set threshold, and holding the shares for several years after acquisition. Meeting these requirements means reviewing well in advance how ownership and the remuneration of family executives are structured, not only at the moment the tax is settled.
What is a family council for?+
It is the body where the family discusses matters affecting its relationship with the business but that are not strictly corporate management: shared values, criteria for admitting new generations, resolving internal disagreements, and monitoring the family protocol. It differs from the board of directors, which is the management body governed by the Spanish Companies Act. Keeping both bodies clearly separate stops family conflicts from interfering in business decisions, and stops business decisions from ignoring family sensitivities.
When should the family protocol be updated?+
It should be reviewed every time a new generation joins, whenever the ownership structure changes significantly (for example, after a succession or an outside shareholder joining), or when there are significant tax or corporate regulatory changes. A protocol designed for two founding shareholders rarely fits the needs of a third generation with several family branches. Ongoing review, more than the initial drafting, is what keeps a family protocol genuinely useful.
What happens if several heirs inherit a family business with nothing agreed in advance?+
Without a prior agreement, the heirs become co-owners of the business by default, which usually leads to deadlocks if they disagree on how to manage it, especially where there is a tied vote between family branches. It is also common for only some heirs to want to work in the business, creating tension with those who are shareholders but not involved in daily management. A well-coordinated family protocol and will allow this outcome to be anticipated, setting clear criteria for joint management or compensation among heirs before succession actually happens.
