TLDR: Sweden doesn’t require a will for most estates since inheritance law already sets out who gets what, but if you want control over your assets, have a blended family, or own property abroad, writing a will matters more than people think. Get it formalized properly and keep your heirs informed.
Why Swedish Inheritance Law Works Differently
Most countries assume you need a will to avoid chaos after you pass. Sweden takes a different approach. The Ärvdabalken, Sweden’s inheritance code, already lays out a clear order of succession. Spouses, children, and other relatives inherit according to a set formula whether you’ve written anything down or not.
That sounds convenient, and for a lot of families it is. But it also means the default outcome might not match what you actually want. If you’re in a long term relationship without marriage, for instance, Swedish law doesn’t automatically protect your partner the way it protects a spouse. Cohabiting partners (known as sambo) have far fewer automatic rights than married couples.
The Sambo Gap
This is where a lot of people get caught off guard. Under the Cohabitation Act, a sambo can claim a share of the shared home and household goods, but that’s about it. Everything else goes to the deceased’s children or other blood relatives, not the surviving partner. If you’ve been with someone for fifteen years but never married, your partner could end up with almost nothing unless you’ve written a will specifying otherwise.
What Happens If You Die Without a Will
Dying intestate in Sweden isn’t the disaster it is in some countries, but it’s not neutral either. Children inherit first, split equally. If there are no children, the estate moves to parents, then siblings, then more distant relatives. A surviving spouse generally inherits everything if there are no children from outside the marriage, but stepchildren or children from a previous relationship can complicate that picture fast.
This is the part people miss. If you remarry and have kids from an earlier marriage, those kids have a legal right to their inheritance even before your current spouse gets full access to the estate. Without a will laying out how you want things divided, the law decides for you, and it doesn’t always divide things the way families expect.
Forced Heirship and the Laglott
Sweden has something called laglott, which is a protected minimum share that children are legally entitled to, regardless of what a will says. You can’t disinherit your kids completely, even if you wanted to. This catches a lot of expats and foreign nationals off guard, since forced heirship isn’t common everywhere. If you’re drafting a will in Sweden, you need to work within this framework rather than around it.
Writing a Valid Will in Sweden
A Swedish will, or testamente, has specific formal requirements. It needs to be in writing, signed by the person making it, and witnessed by two people who are present at the same time and also sign the document. The witnesses can’t be beneficiaries, and they generally shouldn’t be close relatives either, since that can create conflicts later.
There’s no requirement to register a will with a government office, which surprises some people. Instead, it’s common practice to store the will somewhere safe and let a trusted person, lawyer, or bank know where to find it. Some people use a notary or legal firm for safekeeping just so there’s no question about authenticity when the time comes.
Updating a Will After Life Changes
A will isn’t a one and done document. Marriage, divorce, having kids, or acquiring property abroad are all moments where an existing will might need revising. Swedish law doesn’t automatically void a will after divorce the way some jurisdictions do, so if you don’t go back and update it, an ex spouse could technically still be named as a beneficiary. It happens more often than people assume, mostly because nobody thinks to check an old document years later.
Estate Planning for Property Outside Sweden
If you own a summer house in Spain or an apartment in another country, things get more complicated. The EU Succession Regulation (sometimes called Brussels IV) allows people to choose which country’s law applies to their estate, which can simplify cross border inheritance. Without that choice specified in a will, you might end up with two different legal systems arguing over which rules apply to which assets.
Why Working With a Legal Professional Still Matters
Sweden’s system is straightforward on paper, but the details around forced heirship, cohabitation rights, and cross border assets trip people up constantly. A lawyer familiar with Swedish inheritance law can help make sure your will actually reflects your wishes instead of defaulting to a formula that might not fit your family.
Planning ahead isn’t about expecting the worst. It’s about making sure the people you care about aren’t left untangling a legal puzzle during an already hard time.
