Insuring a property portfolio across two jurisdictions

Owning more than one property rarely happens all at once. A main home in one country, a second home bought in the Algarve a few years later, perhaps a flat that was meant for holidays and now takes paying guests, sometimes a unit held through a company. Each was insured when it was acquired, by whoever was convenient, on the terms that suited that moment. Years later the arrangements have accreted rather than been designed, and no single person holds the whole picture. This article sets out how owners with property spanning Portugal and another country can bring that collection of policies into a coherent shape — and where the rules of the Portuguese market change what the cover has to look like.

Why piecemeal cover fails

The common thread in a portfolio built over time is that no two policies were arranged on the same basis. One property sits with a broker in London, another with a Portuguese insurer found through the estate agent at completion, a third on a policy inherited from the previous owner and never revisited. The sums insured were set on different assumptions in different years, the renewal dates fall in scattered months, and the liability limits differ from one policy to the next for no deliberate reason.

None of this is visible while the properties sit quietly. The weaknesses surface at claim time, which is the worst moment to discover them. An owner learns that a sum insured set years ago no longer reflects what the building would cost to rebuild, that a policy lapsed when a renewal notice went to an old address, or that two policies were quietly covering the same risk while a third risk was covered by neither. Because nobody was looking across the portfolio, the gap between what the owner believed was insured and what actually was becomes apparent only when a loss tests it.

A Portuguese property needs a Portuguese policy

The single most common misconception among owners with homes in more than one country is that a domestic policy can be stretched to cover a foreign building. It cannot, and the reason is regulatory rather than a matter of the insurer's goodwill. A property in Portugal has to be insured under a contract that is valid in Portugal: written by an insurer authorised to operate there, supervised by the Autoridade de Supervisão de Seguros e Fundos de Pensões (ASF), and with claims assessed and settled under Portuguese law and practice. A UK or US home insurer, however willing, is generally not in a position to extend a domestic home policy to a house in the Algarve.

The practical consequence is stark. An owner who assumes their existing home insurer covers the Portuguese property is, in most cases, holding a building that is effectively uninsured, because the domestic policy responds only to risks in its own territory. Portuguese cover also carries features a foreign policy will not replicate — local perils, the handling of liability, the language and process of the claim — which is why a property here belongs on a Portuguese multi-risk home policy rather than bolted onto arrangements made abroad.

Occupancy is the variable that decides the claim

Insurers price a home around how it is used, and occupancy is the single factor that shifts cover, conditions and exclusions the most. A main residence, occupied year-round, is the lowest-friction case. A secondary or holiday home that stands empty for stretches carries different terms, because an unoccupied property is exposed to escapes of water, intrusions and slow-developing damage that go unnoticed with nobody there. Many policies impose conditions on properties left empty beyond a set number of consecutive days — that the water be turned off, the property inspected periodically — and a claim can turn on whether those conditions were met.

Letting changes the picture again, and this is where portfolios most often go wrong. A policy written for a second home assumes private, family use. The moment the property takes paying guests it is a different risk: more people through the door, higher wear, greater liability exposure, and in Portugal the specific framework of Alojamento Local (AL) short-let accommodation. The failure is rarely deliberate. A holiday home is let to friends of friends one summer, then listed on a platform the next, and the use drifts from private to commercial without the insurer ever being told.

The most expensive words in a property portfolio are the ones nobody said to the insurer. A holiday home that quietly became a rental is not a smaller version of the cover you bought — at claim time it can be no cover at all.

When an insurer discovers at claim stage that a property described as a holiday home was in fact operating as a short-let rental, it can reduce or decline the claim for non-disclosure, because it never underwrote the risk it is being asked to pay for. For AL properties in Portugal there is also a distinct liability dimension: guests are on the premises commercially, and the expectations around public liability for injury or damage to them are not the same as for a private household. An owner who rents out a second home needs cover written for that use, with the liability limits to match, not a private home policy quietly carrying a commercial risk.

The Portuguese layers: mandatory fire cover and the condominium

Owners of apartments and townhouses in Portugal meet a structure that has no exact equivalent in the UK or US, and misreading it leaves predictable gaps. Where a building is held in horizontal property (propriedade horizontal) — the regime that governs most apartment blocks and many gated developments — fire insurance on the building is mandatory, and it is arranged by the condominium for the common structure. That requirement is often the source of the belief that the flat is “already insured”.

It is insured, but only partly. The condominium's policy covers the shared structure and the compulsory fire risk. It does not reach inside the individual unit: your contents, the fittings and any improvements you have made to the flat, and your own liability as an owner all sit outside it. Relying on the condominium policy alone therefore leaves the whole interior of the property, and your personal liability, uncovered. Owners close that gap with their own multirriscos policy sized to the unit, which sits alongside the condominium cover: the building's shared fabric on one, the inside of your home and your liability on the other. Understanding which policy answers for what — building versus contents versus improvements — is what prevents two owners each assuming the other's insurance will pay.

Making the portfolio consistent

Once each property carries cover valid where it stands and written for how it is used, the work is to make the whole set consistent. The first point is the sum insured, and the most frequent error across a portfolio is anchoring it to the market price. Insurance responds to rebuild cost — what it would take to reconstruct the building — not to what the property would fetch on sale, which includes the land and the location. In a rising market the two drift apart, and owners who insure to value or to purchase price often end up underinsured against the cost of actually rebuilding.

Underinsurance in Portugal carries a specific and often underestimated consequence: the proportional rule (regra proporcional). If a property is insured for less than its correct value, the insurer can settle even a partial claim in the same proportion — a building insured for half its rebuild cost can see a claim met at roughly half, regardless of the repair being well within the sum insured. Setting each property's figure against a realistic rebuild cost, and revisiting it as construction costs move, is what keeps that rule from biting. Sums insured that have gone unrevised for years are among the commonest weaknesses a review turns up.

Consistency also means harmonising the parts that need not differ but usually do. Liability limits set property by property, in different years, tend to vary for no deliberate reason; bringing them to a coherent level is straightforward once they are looked at together. So is the calendar: policies with renewal dates scattered through the year are reviewed in fragments, and aligning them, as far as insurers allow, creates a single point in the year to look across everything at once. None of this requires all the cover to sit with one insurer or in one country. What matters is that one adviser has sight of the full set, so the portfolio is read as a portfolio rather than a drawer of unrelated documents.

When a property is held through a company

Some properties in a portfolio are owned not personally but through a structure — a Portuguese Lda, a US LLC, or an offshore holding company. Whatever the reason for that arrangement, it changes who the policy must name, and getting this wrong is a genuine claims problem rather than a technicality. The policyholder and the insured interest have to match the legal owner. If the building is owned by a company but the policy is written in an individual's name, or the reverse, the party suffering the loss may not be the party the insurer contracted with, and the claim can founder on that mismatch.

The insurance point here is narrow. Whether a property should be held through a company, and the tax and legal consequences of doing so, are questions for the reader's own tax and legal advisers, and this brokerage does not advise on them. What the insurance arrangement must do, once the ownership is settled, is name the right entity as policyholder and reflect the real insured interest — so that when a claim arises, the policy responds to the party that actually owns the building.

What a portfolio review looks like

Bringing a scattered set of policies into order is a methodical exercise rather than a dramatic one. It starts with an inventory: every property, where it is, how it is owned, and how it is actually used through the year — occupied, empty for periods, let long-term, or run as short-let or AL. Against each property sit its current policy, the sum insured, the basis that figure was set on, and the liability limit. Laid out together, the pattern that was invisible while the documents lived apart becomes clear.

From there the review looks for two things: overlaps, where more than one policy covers the same risk and the owner is paying twice, and gaps, where a risk is covered by nothing — a let property on private-use terms, a Portuguese flat leaning on the condominium's fire cover alone, a sum insured that has fallen behind rebuild cost, a policy in the wrong name. Each of those is fixable once seen. The value of the exercise is less in any single correction than in someone finally holding the whole picture, across both jurisdictions, and keeping it aligned as the portfolio changes.
