In short. Not everything a liability policy leaves out is an exclusion. There are four distinct families: what the law forbids insuring —the benefits surcharge, penalties, wilful misconduct—, what simply defines the risk bought, what belongs to another class of business —pollution, cyber, product recall, D&O— and what is negotiated at placement. Only limiting clauses require special highlighting and specific written acceptance under article 3 of the Spanish Insurance Contract Act. In large risks, not even that.
The Spanish liability class wrote €2,342 million in premiums, up 5% and accounting for 4.7% of non-life business, according to ICEA figures reported in the trade press (2026). Almost the entire conversation between company, broker and market revolves around two numbers: the limit and the premium. The real content of the contract sits a few pages further back, in the exclusions.
And there is one corporate liability that no policy in the market can cover, because Spanish law declares it uninsurable and voids any agreement that attempts to shift it.
Not everything left uncovered is an exclusion
This is the original confusion, and it contaminates everything else. A policy wording leaves things out for legally very different reasons, and that difference decides who wins the litigation.
The First Chamber of the Spanish Supreme Court, in judgment 853/2006 of 11 September, settled the distinction that still governs: risk-defining clauses set out what risk is covered, in what amount, for what period and in what territory; limiting clauses restrict or condition the insured's right once the risk has materialised.
The consequence is what matters. Article 3 of the Spanish Insurance Contract Act (Law 50/1980) requires clauses that limit the insured's rights to be specially highlighted and specifically accepted in writing. Risk-defining clauses are not subject to that requirement: they form part of the description of the risk.
Put another way: where your declared activity does not include a line of business, there is no exclusion to challenge, because that risk was never bought. Where a clause cuts back a right after the loss, the way it was incorporated into the contract becomes decisive.
The boundary is not intuitive
It is worth resisting mechanical rules. The Supreme Court sets the test case by case, and two recent decisions show it clearly.
On employers' liability, judgment 1479/2023 of 23 October treated as risk-defining a clause setting cumulative conditions determining cover: it did not cut back a right already accrued, it described the circumstances in which the right arose.
In the opposite direction, judgment 1581/2025 of 5 November classified as limiting something as apparently innocuous as a sub-limit per victim. It does not describe the risk: it cuts it back. If it fails to meet the requirements of article 3, it cannot be relied upon and the insurer responds up to the limit per claim.
The nuance is finer still: judgment 57/2024 of 18 January confirms that the sum insured under article 27 of the Spanish Insurance Contract Act is indeed risk-defining and can be relied upon against a claimant exercising the direct action. An overall limit, risk-defining; a sub-limit per victim, limiting. The structure of limits, sub-limits and deductibles is not a technical detail: it is where enforceability is decided.

What the law forbids insuring
Here there is no negotiation available, no buy-back extension and no alternative market.
The clearest case is the benefits surcharge. Article 164.1 of the Spanish General Social Security Act quantifies it at between 30% and 50% of the economic benefits arising from an accident at work or occupational disease, depending on the seriousness of the breach. Article 164.2 places it directly on the infringing employer and renders void as a matter of law any agreement or contract to insure, offset or transfer it. Article 164.3 adds that it is independent of and compatible with liabilities of every kind. We develop the point in why the benefits surcharge cannot be insured.
Alongside the surcharge, administrative fines and penalties are excluded as a general principle. This does not rest on a single express prohibition like the one governing the surcharge, but on the personal and punitive nature of a penalty: passing it to a third party would hollow out its function. Legal defence costs in the proceedings are a different matter and may well be covered, subject to the terms of each policy.
And wilful misconduct. There is no insurable risk where damage is caused intentionally, because the fortuity on which the contract rests disappears.
Does the injured party still get paid if the damage was intentional?
A false conclusion is often drawn from the above: "the policy does not cover wilful misconduct, therefore the claimant recovers nothing." That is not how it works.
Article 76 of the Spanish Insurance Contract Act grants the injured party a direct action against the insurer, and that action is immune to the defences the insurer could raise against its own insured. The same provision expects the insurer, having paid, to recover from the insured where the conduct was wilful.
The wilful misconduct exclusion, therefore, can be relied upon against the insured, not against the third party. The victim is paid; the insured who acted wilfully ends up repaying the amount. The insurer does retain its personal defences against the claimant and the defence of the claimant's sole fault.
For a board, the practical reading is simple: excluding wilful misconduct does not protect the company from paying, it shifts who pays in the last instance.
Exclusions that are really doors into another class of business
A good part of what a wording excludes is not a gap in cover: it is a market with its own product, its own underwriting and its own rating. Presenting these as "what you are not covered for" is a common misreading.
- Pollution and environmental damage → an environmental liability policy. General liability, where it admits pollution at all, usually restricts it to sudden and accidental events, with a sub-limit.
- Cyber incidents, data breach and damage to information → cyber insurance, with its response, business interruption and third-party claim sections.
- Product recall. The logistical cost of withdrawing a batch from the market is not damage to a third party, which is why it falls outside product liability unless expressly extended.
- Acts of directors and officers → D&O. This is the personal liability of the board, with their own assets at stake.
A well-built programme does not argue about these exclusions: it coordinates them, so that no no-man's-land is left between two policies.
A map of the most common exclusions
| Typical exclusion | Family | Why it is excluded | Where it is covered, if at all |
|---|---|---|---|
| Benefits surcharge | Uninsurable by law | Article 164.2 of the General Social Security Act voids any agreement as a matter of law | Under no policy |
| Administrative fines and penalties | Uninsurable (general principle) | Personal, punitive nature of the penalty | Under no policy; legal defence costs may be covered |
| Damage caused by wilful misconduct | Uninsurable by law | No fortuity; the insurer may recover from the insured (art. 76 LCS) | The third party is paid under the direct action; the insurer then recovers |
| Undeclared activity | Definition of the risk | It never formed part of the risk bought | By extending the declared activity |
| Events outside the territorial or temporal scope | Definition of the risk | It sets the period and territory of cover | By extending territory and retroactive date |
| Gradual pollution | Belongs to another class | Progressive loss pattern, specialist underwriting | Environmental liability |
| Cyber incidents and damage to data | Belongs to another class | Technology risk with its own product | Cyber policy |
| Product recall | Belongs to another class | Management cost, not damage to a third party | Product recall cover or express extension |
| Directors' and officers' liability | Belongs to another class | Personal liability of the board | D&O |
| Property in care, custody or control and property being worked upon | Negotiable | It is in the insured's custody or being worked on | Specific section with its own sub-limit |
| Damage to the insured's own work | Definition / negotiable | Defective performance, not damage to a third party | Completed operations cover, with caveats |
The precise content of each row varies: the label, the scope and the carve-outs are governed by the specific terms of each policy.
The ones that really are negotiable
This is the useful ground at placement, and where a brokerage either proves its worth or does not.
The most relevant negotiable exclusions are usually four: property in care, custody or control and property being worked upon, completed operations —damage manifesting after the works or the service have been handed over—, hot works —welding, cutting, oxy-fuel cutting, with the aggravated fire risk they carry— and contractual liability assumed above what the law imposes.
All of them are open to discussion: deletion, a specific sub-limit, a separate deductible or associated risk-management conditions. None of them is resolved by asking for a price.
There is a nuance most sector content explains poorly, and it is worth fixing. Liability insurance is not a quality guarantee or a performance bond. The First Chamber of the Spanish Supreme Court made the point in judgment 730/2018 of 20 December, recalling that public liability insurance covers non-contractual liability arising from the operation of the business, and does not insure the correct performance of the contracted service or damage to the property being worked upon. Defective performance of what was agreed has other instruments; liability insurance responds to the damage that defect causes a third party, on the terms of each wording.
Before renewing, it is worth knowing which exclusions are structural and which are on the table. Let us review your wording together.
If you are a large account, a formal defect will not save you
This is where the most repeated piece of advice on the internet breaks down: "if the exclusion was not highlighted and signed, they cannot apply it to you." For a large account, that is simply false.
The second paragraph of article 44 of the Spanish Insurance Contract Act provides that the mandate of article 2 —the mandatory character of the Act— does not apply to insurance contracts covering large risks. In those contracts the formalities of article 3 do not operate: a limiting clause that was poorly highlighted remains valid and enforceable. The First Chamber has applied this to claims-made clauses, among other cases, in judgment 545/2020 of 20 October.
If your company exceeds the thresholds in article 11 of Law 20/2015, the law will not rescue you from a badly negotiated wording. The only defence is exercised before signing, in the liability policy and in the placement process. After that, there is no formal defect left to rely on.
The role of an independent broker
Two quotations with the same limit and a similar premium can conceal wordings that are not comparable: one excludes hot works outright, another admits them subject to risk-management measures; one caps completed operations at twelve months, another at thirty-six. Reading them line by line is our job. As an independent brokerage registered with the Spanish DGSFP under reference J0140, we act on the client's mandate and not on the insurer's.
In practice that means three things: we negotiate the wording and not only the price, we coordinate the referrals between classes of business so that no gaps are left between policies, and when a claim arises we argue the classification of the clause on the company's side.
Frequently asked questions
What exclusions does a liability policy carry? They fall into four families: what is uninsurable by law (the surcharge, penalties, wilful misconduct), what merely defines the risk (activity, territory, period, sum insured), what belongs to another class (pollution, cyber, product recall, D&O) and what is negotiable (property in care, custody or control, property being worked upon, completed operations, hot works). The detail depends on each wording.
What is the difference between an exclusion and the definition of the risk? A risk-defining clause sets out what risk is covered, in what amount, period and territory; a limiting clause restricts a right already accrued. Only the latter must be specially highlighted and specifically accepted in writing under article 3 of the Spanish Insurance Contract Act.
Can a claim be declined under a clause I never signed? If it is a limiting clause and was neither highlighted nor accepted in writing, article 3 denies it effect. If it is risk-defining, no such formality is required. And if the contract is one of large risks, the second paragraph of article 44 disapplies the mandatory character of the Act: the clause remains valid.
Does the policy cover the benefits surcharge? No. Article 164.2 of the Spanish General Social Security Act places it directly on the infringing employer and renders void as a matter of law any agreement to insure, offset or transfer it. It is not a question of wording or of premium.
Does the policy cover pollution? General liability usually excludes it, or admits it only where sudden and accidental, with its own sub-limit. Gradual pollution and environmental remediation belong to an environmental liability policy, subject to the terms of each contract.
