How to read a Portuguese insurance policy

Almost everything that decides what your insurer pays you is written in the policy rather than in the law. Three words do most of the work: sum insured, premium and deductible. The Portuguese Insurance Contract Act leaves all three to the parties. This guide explains what each one means, who sets it, and why two policies with the same price can pay very different amounts for the same loss.

TL;DR

The policy is the contract, and it is the policy that fixes the numbers, not the law. Article 49(3) of Decreto-Lei 72/2008 expressly lets the parties set deductibles, indemnity tiers and other contractual terms that condition what the insurer pays, so looking for a legally defined standard deductible is looking for something that does not exist. Of the three words that decide the outcome, the sum insured is the most the insurer can pay, the premium is what you pay for the cover, and the deductible is the share of the loss you carry. The deductible is the one that misleads, because it is not always subtracted: in some policies it works as a threshold, and above it the insurer pays the loss in full.

The three words that decide the outcome

A policy runs to dozens of pages, but most of the questions people ask after a loss come down to three numbers: the sum insured, the premium and the deductible. It is worth finding them before you need them.

The starting point is that none of the three is set by law. Article 49(3) of Decreto-Lei 72/2008 lets the parties set deductibles, indemnity tiers and other contractual terms that condition what the insurer pays. The law organises the contract; the figures belong to the contract.

Sum insured: the ceiling

The sum insured is the most the insurer undertakes to pay. Above it, the loss is yours, however well documented.

There is a duty here that surprises people. Article 49(2) provides that, except where the law determines otherwise, it falls to the policyholder to tell the insurer the value of the property, right or estate the contract relates to, at inception or during the contract, for the purpose of setting the sum insured. The insurer is not going to value your house on its own initiative: the figure in the policy is, as a rule, the one you declared.

When the sum insured sits below what the property is actually worth, the problem is no longer the deductible but under-insurance, a situation with rules of its own, which the Insurance Contract Act handles in a separate article.

Premium: the price of cover

The premium is what you pay so that the cover exists. It is not savings and not a deposit: there is no refund for a claim-free year, and a higher premium does not in itself mean a larger payout.

What the premium reflects is the risk the insurer accepts and the covers you bought. Two contracts with similar premiums can behave very differently in a claim if their sums insured or deductibles differ.

Missing a premium is not a late payment: it ends the contract

This is the part of a policy most people discover too late. Article 61 of Decreto-Lei 72/2008 provides no grace period, and the consequences are automatic:

"1. Failure to pay the initial premium, or its first instalment, on the due date causes the automatic termination of the contract from the date it was entered into."

Note the last part. The contract does not end on the day the payment was missed: it is treated as terminated from inception. Someone who never paid the first premium was never covered, not even for the days that passed in between.

For later years the rule differs but is equally dry: paragraph 2 says non-payment "prevents the contract from being extended", so the policy simply does not renew. Paragraph 3 adds that failing to pay an instalment during the year causes automatic termination on that instalment's due date.

There is one exception worth knowing. If what went unpaid was an additional premium arising from a change to the contract, paragraph 4 provides that it is the change that fails, with the contract surviving "with the scope and on the terms in force before the intended modification". The old policy stands; what does not take effect is the amendment.

Deductible: the part that stays with you

The deductible is the share of the loss that is not paid to you. It appears in three shapes, and the last two require arithmetic:

  • a fixed amount in euros;
  • a percentage of the sum insured, common in home multirriscos cover;
  • a percentage of the loss, common in own-damage motor cover, almost always with a minimum.

The minimum causes half the confusion. Under a clause reading "10 % subject to a minimum of 250 EUR", an 1 800 EUR loss does not produce a 180 EUR deductible: it produces 250 EUR, because the minimum prevails.

The distinction that changes everything

There are two species of deductible, and policies are not always explicit about which one you bought.

A deductible proper is subtracted from every claim. On a 1 000 EUR loss with a 250 EUR deductible, you receive 750 EUR.

A threshold deductible, also called simple, is only a floor. Below it the insurer pays nothing; from it upwards the insurer pays the loss in full. On the same example, you receive 1 000 EUR.

Same loss, same deductible, 250 EUR apart. That is why mental arithmetic rarely lands on the right figure, and why the deductible calculator exists.

Where to find each thing

A policy comes, as a rule, in three layers:

  • General Conditions: the definitions and, above all, the exclusions. This is where it is decided whether what happened to you is a covered loss at all.
  • Special Conditions: the rules for any optional covers you bought.
  • Particular Conditions: your figures: sum insured, premium, deductibles, and the people and property named.

The temptation is to read only the third, because it is short and carries the numbers. It is also the one that explains least about why a claim might be refused.

Who is who in the contract

Three roles the policy separates and everyday conversation merges:

  • the policyholder enters into the contract and pays the premium;
  • the insured person is the one whose risk is covered;
  • the beneficiary is the one who receives the payment.

In a life policy tied to a mortgage, for example, all three can be different parties. Confirming which one you are avoids finding out at the worst moment.

Common mistakes

  • Looking for the standard or legal deductible

    There is none. Article 49(3) of Decreto-Lei 72/2008 lets the parties set deductibles and indemnity tiers, which means the figure is contractual. Two policies in the same line, at the same insurer, can carry different deductibles because they were contracted differently. The useful question is not what the deductible is, but what your policy says.

  • Assuming the deductible is always subtracted

    Only a deductible proper is subtracted. A threshold deductible, also called simple, works as a floor: below it the insurer pays nothing, at or above it the insurer pays the loss in full. Same word, same figure, and results that differ by exactly the deductible.

  • Confusing the sum insured with what the property is worth

    They are different, and the gap is where trouble starts. The sum insured is what the policy says; the value is what the property is actually worth. When the first falls below the second you are under-insured, and article 49(2) is clear about who states the value: it falls to the policyholder to tell the insurer the value of the property, at inception or during the contract.

  • Thinking a higher premium means a bigger payout

    The premium pays for the cover contracted, not for the size of the indemnity. What decides how much you receive is the combination of the sum insured, the covers you bought and the deductible. A higher premium may simply reflect a higher risk, a younger driver for instance, rather than better terms.

  • Reading only the Particular Conditions

    The Particular Conditions carry your figures, but the exclusions and definitions live in the General Conditions, and that is where it is decided whether your situation is a covered loss at all. The policy is both together, and skipping the second half is the most common reason for an unexpected refusal.

Frequently asked questions

What is an insurance policy in Portugal?
It is the document that embodies the insurance contract: it identifies the parties, the risk covered, the sum insured, the premium, the deductibles and the exclusions. In practice it comes in three layers: General Conditions, which set the product's rules and exclusions, Special Conditions, which govern optional covers, and Particular Conditions, which carry your specific figures.
What does sum insured mean?
It is the maximum the insurer undertakes to pay. It works as a ceiling: a loss above it is not fully indemnified. Article 49(2) of Decreto-Lei 72/2008 provides that, except where the law determines otherwise, it falls to the policyholder to tell the insurer the value of the property, right or estate the contract relates to, for the purpose of setting the sum insured.
What is the difference between a premium and a deductible?
The premium is what you pay the insurer to have the cover, usually periodically. The deductible is the share of a loss you carry when a claim happens. One is the cost of being insured, the other the cost of using the insurance, and they move in opposite directions: higher deductibles usually come with lower premiums.
Who is the policyholder?
The policyholder is the person who enters into the contract with the insurer and owes the premium. They may or may not be the same as the insured person, whose risk is covered, or the beneficiary, who receives the payment. In many personal lines these are three separate roles, and it is worth confirming in the policy which one is yours.
Does Portuguese law set a minimum or maximum deductible?
Not as a general rule. Article 49(3) of Decreto-Lei 72/2008 provides that the parties may set deductibles, indemnity tiers and other contractual terms that condition what the insurer pays, so the figure comes from the contract. Some compulsory lines have their own rules about what can be raised against an injured third party, which is a different question from the one between you and your insurer.
Use the deductible calculator to see what your insurer pays in your case, using the figures written in your own policy.
