You bought a home in the Algarve to enjoy it now and to leave it to your children later. The "later" part is where many foreign owners are caught off guard. Portuguese inheritance law does not simply follow your wishes the way an English, Irish, or American will might. It reserves a fixed portion of your estate for close family by law, and it decides which country's rules apply based on where you live, unless you take a specific step to change that.

This guide explains the three things that actually determine whether your Portuguese property passes the way you intend: forced heirship, the EU Succession Regulation, and the ownership structure you choose. It is written for international owners and is current as of 2026. It is general information, not legal or tax advice for your specific situation. For that, speak to a qualified Portuguese lawyer.

Forced heirship: the rule that surprises foreign owners

Most common-law countries let you leave your assets to whomever you choose. Portugal does not. Under the Portuguese Civil Code, a portion of your estate, called the legítima (the "reserved" or "forced" share), is set aside by law for your closest relatives, known as herdeiros legitimários (forced heirs).

You cannot freely give this portion away, whether by will or by lifetime gift, except in narrow cases of disinheritance defined by law.

The forced heirs are, in order: your spouse, your descendants (children, then grandchildren), and, where there are no descendants, your ascendants (parents, then grandparents). T

he part of your estate that is reserved depends on who survives you.

As a guide:

• Spouse and children together: two-thirds of the estate is reserved; one-third is freely disposable.
• Spouse alone (no descendants or ascendants): one-half is reserved.
• Children but no spouse: one-half is reserved if there is one child, two-thirds if there are two or more.
• Ascendants only: typically one-half (parents) or one-third (more distant ascendants).

The portion you can leave freely is called the quota disponível (available quota). Everything outside the available quota belongs to the forced heirs by operation of law. A will that tries to give the family home entirely to one child, a new partner, or a charity can be challenged and reduced to respect the legítima.

This is why a generic foreign will, drafted without Portuguese advice, often does not do what its author assumed. For owners with blended families, unmarried partners, or stepchildren, the gap between intention and outcome can be wide.

The EU Succession Regulation: choosing which country's law applies

Here is the part that gives foreign owners real control. Since 17 August 2015, cross-border inheritances in most of the EU are governed by the EU Succession Regulation (Regulation (EU) No 650/2012), often called Brussels IV.

The default rule is straightforward: the law that governs your entire succession is the law of the country where you had your habitual residence at the time of death. So if you have retired to the Algarve and made Portugal your home, Portuguese succession law, including forced heirship, applies to your worldwide estate by default.

The Regulation also gives you a powerful option called professio juris, a choice of law. You may instead choose the law of a country of your nationality to govern your succession, made expressly in your will. A British national resident in Portugal, for example, can elect for the law of their nationality to apply, which does not impose forced heirship in the same way. That single clause can be the difference between freely leaving your Algarve home as you wish and being bound by the legítima.

Two points international owners should not miss. First, Denmark and Ireland are not bound by the Regulation, which affects how their nationals and assets are treated. Second, choosing your national law is a deliberate act: if you do nothing, the law of your habitual residence applies. The choice must be made correctly in a valid will, which is exactly where professional drafting matters. You can read more in our overview of Legal and tax guidance.

What inheriting property actually costs in Portugal

Good news for most families: Portugal does not levy an inheritance tax in the classic sense. What exists is Stamp Duty (Imposto do Selo) on the transfer of assets on death, and the closest relatives are exempt.

According to the Portuguese government (gov.pt) and the Tax and Customs Authority, the following are exempt from Stamp Duty on inheritance: the surviving spouse or de facto partner, descendants (children and grandchildren), and ascendants (parents and grandparents). For everyone else, such as siblings, nieces, nephews, or unrelated beneficiaries, the rate is 10% on the value transferred on death.

There are also administrative steps. The death must be reported to the Tax Authority and a Stamp Duty declaration filed, but only if the deceased left assets to transmit. This is done by the cabeça de casal (the estate administrator, usually the surviving spouse or closest heir) by the end of the third month after the month of death, using the official Modelo 1 form. The reporting itself is free of charge.

A practical implication: leaving the Algarve property to your children or spouse is, in most cases, Stamp Duty exempt. Leaving it to a partner you never married, or to more distant relatives, can trigger the 10% charge, another reason structure and documentation matter.

How foreign owners structure property for a clean inheritance

Putting it together, here is how international families typically reduce friction:

• Make a Portuguese will, and consider the law choice. A will drafted in Portugal, covering your Portuguese assets and including a clear professio juris clause if you want your national law to apply, is the single most effective step. It speeds up the process and removes ambiguity for your heirs.
• Decide consciously between habitual-residence law and national law. If you are happy for Portuguese forced heirship to apply, you may need to do nothing. If you want freedom of disposition, the choice of your national law must be expressed correctly. This is a decision to make with advice, not by default.
• Check how the property is owned. Whether the home is held jointly, individually, or through a company changes how it passes and how it is taxed. Co-ownership and the marital property regime (for married couples) interact with the legítima in ways that are easy to get wrong.
• Plan for the tax-exempt path where possible. Because spouses, descendants, and ascendants are exempt from Stamp Duty, keeping the intended beneficiaries within that group, or planning around it, can avoid the 10% charge on other beneficiaries.
• Coordinate across borders. Your Portuguese will and your home-country will must not contradict each other, and your choice of law should be consistent. Cross-border estates fail most often at the seams between two legal systems.

Why this matters for Algarve buyers specifically

The Algarve attracts exactly the buyers for whom these rules bite hardest: international retirees, second-home owners, and families with assets and heirs in more than one country. Many arrive through residency routes such as the Portugal D7 visa guide, establish habitual residence here, and never revisit what that means for their estate. If part of the appeal was leaving a legacy in one of Europe's best retirement destinations, the legacy is worth structuring properly.

Frequently asked questions

Can I leave my Algarve home to whoever I want?

Not automatically. If Portuguese law applies, forced heirship reserves a fixed share for your spouse, children, or parents. You can gain more freedom by validly choosing the law of your nationality under the EU Succession Regulation, where that law permits it.

Will my children pay inheritance tax in Portugal?

Portugal has no classic inheritance tax. Spouses, descendants, and ascendants are exempt from Stamp Duty on inheritance. Other beneficiaries pay 10% on the transferred value.

I already have a will in my home country. Is that enough?

Often not. A foreign will may not address Portuguese assets cleanly, may omit the choice-of-law clause, and can create delays. A coordinated Portuguese will is usually worthwhile.

Does Brexit change this for British owners?

The EU Succession Regulation applies based on assets and residence within participating EU states, not on the deceased's EU membership status, so British nationals can still benefit from choosing their national law. Tax treatment is separate and should be checked individually.

The bottom line

Inheriting property in Portugal is not difficult, but it is governed by rules that differ from what most foreign owners expect. Forced heirship sets a floor on what your family receives. The EU Succession Regulation lets you choose which country's law applies, if you act deliberately. And the tax exemptions for close family make most transfers cheaper than people fear. The owners who get clean outcomes are simply the ones who planned, with proper advice, before it mattered.
