Forfeiture of cover: when a Belgian insurer can refuse to pay

What is forfeiture of cover in car insurance?

Forfeiture of cover, known in Belgium as déchéance de garantie, denies the insured any payout for a claim that was in fact covered, on the ground that a specific obligation imposed by the policy was not respected. The contract is not cancelled, it keeps running, premiums remain due and later claims stay covered. Only the claim at hand falls away.

It is the most misunderstood sanction in the sector, and not only by policyholders.

Type the question into a search engine from Belgium and you will land on Ornikar, LeLynx, Meilleurtaux, Assurpeople or Luko. Those pages are all serious work. They all cite article L113-1 of the French Insurance Code and its famous requirement of « very apparent characters ». None of that applies to a Belgian policy, where the legal test is entirely different and, on at least one point, distinctly more favourable to the insured.

Forfeiture, exclusion and nullity: three sanctions, three regimes

The three words come up in the same conversations and describe three mechanisms with different causes, different effects and different legal bases.

The distinction is not academic. It governs your defence.

Against an exclusion, the argument turns on how the risk is defined: does your situation fall inside the listed case or not? Against a forfeiture, the argument turns on causation, which is much friendlier ground. Against nullity, the argument turns on your intent when you took out the policy, which means the insurer must prove bad faith.

When can a Belgian insurer actually invoke forfeiture?

Two conditions, cumulative, and the second is the demanding one.

Article 65 of the Belgian Insurance Act of 4 April 2014 provides that a policy may only stipulate partial or total forfeiture of the right to the insurance benefit for non-performance of a determined obligation imposed by the contract, and on condition that the breach is causally related to the occurrence of the claim.

Break that down.

First test, the determined obligation. A clause vaguely requiring the insured to show « normal care » or to follow « good practice » does not qualify. The obligation must be identifiable: lock the vehicle, activate the anti-theft device, do not leave the keys inside, have the car serviced, stay within a declared mileage.

Second test, the causal link. The breach must have contributed to the claim happening. A clause requiring an annual service cannot ground forfeiture on a theft in a car park, because the missed service has nothing to do with the theft. That second test knocks out a great many refusals.

Remember the shorthand: no precise obligation, no forfeiture. No causal link either.

What did the Court of Cassation change on 10 March 2025?

It settled a question insureds kept raising, and not in the direction they hoped.

In ruling no. C.24.0343.F of 10 March 2025, the Belgian Court of Cassation heard a stolen-vehicle case. The insurer refused payment on the forfeiture clause at article 4.2 of its general conditions, which listed prevention duties: locking the vehicle, no keys left on board. The insured replied that article 62, paragraph 2 of the 2014 Act reserves denial of cover for cases of gross fault expressly listed, so ordinary carelessness could not suffice.

The Court rejected that reading. Articles 62 and 65 pursue different aims and belong to autonomous regimes: article 62 governs exclusion for gross fault, article 65 governs contractual forfeiture. Forfeiture may therefore take effect without gross fault by the insured, provided the obligation is determined and the causal link established.

Translated for a Belgian driver: everyday inattention, leaving the keys in the ignition while nipping into the bakery, can be enough to bring down theft cover if your policy spelled it out. That is exactly why I never recommend a policy without having read its exclusions and prevention duties first.

Does a late claim declaration forfeit cover?

No, and this is one of the points where Belgian law protects far better than the French pages topping the results suggest.

Article 74 of the Act of 4 April 2014 requires you to report a claim as soon as possible and, in any event, within the period set by the contract. The same article immediately adds a safety valve: the insurer cannot rely on the contractual deadline being missed if the report was made as quickly as could reasonably be done. Someone hospitalised for three weeks is therefore not out of the game because the policy announced eight days.

Article 76 finishes fencing in the sanction. Where the breach causes harm to the insurer, the insurer is entitled to a reduction of its benefit matching the harm it suffered, no more and no less. Outright denial of cover is possible only where there was fraudulent intent.

A worked example fixes the idea. You report bodywork damage six weeks late. The insurer puts at €300 the extra survey cost caused by traces disappearing from the scene, on a payout of €2,400. It may deduct those €300, and it must justify the figure. It may not refuse the €2,400.

Five forfeiture clauses found in almost every Belgian car policy

The list varies between companies, but a common core recurs at AG Insurance, Ethias, AXA, KBC, Belfius Insurance and P&V, under similar wording.

• Anti-theft prevention duties. Locking, removing the keys, activating an approved alarm where the policy requires it. This is the clause behind the March 2025 ruling, and by far the most frequently applied in practice.
• Driving under the influence. Alcohol above the legal limit, drugs, refusing a test. It appears sometimes as an exclusion for gross fault under article 62, sometimes as a forfeiture, and the label chosen changes how much room you have to argue.
• Driving without a valid licence. Expired, suspended, never obtained, or the wrong category for the vehicle. A foreign licence not converted after settling in Belgium is a more common trap than newcomers expect.
• Use that does not match what was declared. A car insured for private use and driven for paid delivery, commercial ride-sharing or car-sharing is a risk the insurer never priced.
• Obstructing the survey. Repairing before the loss adjuster arrives, disposing of damaged parts, refusing to hand over requested documents. Article 74 requires you to supply all useful information without delay.

One remark covers all five: read the stated sanction, not only the obligation. Some policies provide for full forfeiture where others settle for a higher deductible or a capped recourse.

How do you spot forfeiture clauses in your general conditions?

Allow ten minutes, on the PDF your broker handed you or that the company publishes online.

1. Open full-text search and type in turn « déchéance », « perd le droit », « ne sera pas indemnisé », « obligations de l'assuré », « sous peine de ». Those phrasings hold almost every clause of this kind. Belgian policies are issued in French or Dutch, so search the language of your own document.
2. Note the article number of each hit. That number is what you will demand later if a refusal arrives, and its absence from a refusal letter is itself a signal.
3. Separate the two blocks. The « exclusions » chapter lists risks never covered. The « obligations of the insured » chapter lists behaviour whose breach opens forfeiture. Conflating them distorts the whole analysis.
4. Check whether an obligation genuinely applies to you. A mandatory alarm, a locked garage overnight, a mileage cap: these terms are sometimes accepted in exchange for a lower premium, then forgotten.
5. Turn to your particular conditions. The personalised document may restrict or adjust what the general conditions say, and it prevails.

Should forfeiture clauses drive your choice of policy?

Yes, as soon as two offers are close on price and cover.

Two comprehensive policies quoted a few euros apart can diverge sharply here. One requires an approved alarm above a certain vehicle value, the other does not. One provides total forfeiture for driving under the influence, the other a capped recourse. One requires overnight parking in a closed garage in certain areas, the other says nothing. None of these gaps shows on a price grid, and yet they decide the fate of your payout the day something happens.

The useful reflex fits in one sentence. Before signing, ask your intermediary for the list of obligations whose breach triggers forfeiture, in writing, and hold it against how you actually use the car.

A driver who parks on the street in Brussels does not have the same ideal policy as a commuter with a garage in Namur. The car insurance comparison tool puts the formulas side by side, and the ranking of the best car insurers sets out company by company what each one covers and refuses. If you are still unsure about the level of cover, the quiz takes two minutes.

If a refusal has already been notified, the ground shifts and the question becomes procedural: challenging the survey, pricing the harm relied on, referring the matter to the mediator. The Insurance Ombudsman handles Belgian consumer complaints free of charge, and the FSMA, the Belgian financial services and markets authority, supervises insurers and intermediaries. For the step-by-step route after a claim, our article on reporting a car insurance claim sets out the deadlines and the documents to gather.

One last marker, often decisive. A refusal letter based on forfeiture must identify the clause relied on and the breach alleged. Where it offers only a general reference to the general conditions, with no article number and no description of the behaviour at issue, ask for that detail in writing before starting anything else: everything that follows will rest on that document, including any file with the mediator. Companies do reply, and the reply itself is often instructive.
