Sunil RaoWhen moving to Sweden, many expats choose to live with their partners under Sweden's legal framework for cohabitation. In Sweden, couples living together in a marriage-like relationship are regulated by the Sambo Act (Sambolagen 2003:376).
While this framework grants legal rights to partners without formal marriage, it introduces substantial financial risks for property owners. The law dictates that certain assets are split equally upon separation, regardless of who paid for them.
The 50/50 Joint Property Rule
The core of the Sambo Law is the definition of joint property (samboegendom). This only includes the joint home (gemensam bostad) and joint household goods (gemensamt bohag).
If a home or household item was purchased with the intention of joint use (för gemensamt bruk), it is split 50/50 upon separation. This applies even if only one partner paid 100% of the purchase price and holds the entire mortgage.
| Asset Category | Sambo Status | Legal Default Split |
|---|---|---|
| Property bought for joint use | Joint Property | Split 50/50 regardless of financial contribution |
| Property owned before meeting | Separate Property | Excluded from division unless bought to live in together |
| Bank accounts & Stocks | Separate Property | Always kept by the individual owner |
What this means for us: if you buy a SEK 4,000,000 apartment in Göteborg and your partner moves in with you, they are legally entitled to SEK 2,000,000 of its value if you separate, even if they never paid a single krona.
How to Protect Your Capital with a Samboavtal
To override the default 50/50 division of your home, you must write and sign a cohabitation agreement (samboavtal). This private legal contract specifies that the Sambo Act will not apply to your home or specific assets.
If you paid unequal amounts toward the downpayment (kontantinsats), a Samboavtal alone is not enough. You must also write a promissory note (skuldebrev) stating exactly how much one partner owes the other to ensure the difference is repaid.
Exceptions and Key Deadlines
The Sambo Law has a strict statute of limitations. A former partner has exactly **one year** from the date the relationship officially ends to request a division of property (bodelning). If no request is made within 12 months, the right to split the assets is lost.
Additionally, properties owned by one partner prior to the relationship are generally excluded, unless the property was bought specifically to serve as the couple's first joint home.
What this means for us: if you already owned an apartment before you met your partner, they cannot claim half of it, unless you sell it to buy a new place together.
NordDaily Tips
Actionable Tip: If you buy a property in Sweden where one partner pays the down payment, draft a Sambo agreement (Samboavtal) and a co-ownership agreement (skuldebrev) immediately. Without these, the entire apartment will be split 50/50 upon separation, regardless of who paid for it.

Frequently asked questions
Does the Sambo Law apply to bank accounts or stock portfolios?
No. The Sambo Law only applies to your joint home and joint household goods. Private bank accounts, stock portfolios, cars, and assets acquired before or during the cohabitation for personal use remain separate property.
How long after separation can a partner request a property division?
Under the Sambo Act, a former cohabiting partner must formally request a division of property (bodelning) within one year of the date the cohabitation ended.
Does a Samboavtal need to be registered with the government?
No. Unlike prenuptial agreements (äktenskapsförord), a Samboavtal is a private contract and does not need to be registered with Skatteverket. It only needs to be signed by both partners.
What happens if one partner paid the entire downpayment?
If the home was bought for joint use, it is still split 50/50. To protect your unequal cash input, you must sign a Samboavtal to override the law and a separate promissory note (skuldebrev) to secure the debt.
