Cohabitation (Unmarried Couples) in Denmark (2026 Legal Guide) — Rules & Requirements
About this article
Sourced from Danish Acts of Parliament (love), executive orders (bekendtgørelser), and official government guidance. Written in plain language for general understanding — this is educational content, not legal advice. Our editorial standards
What is this right?
Denmark has no single cohabitation statute — unmarried cohabitants have far fewer automatic rights than spouses:
- No automatic division of property: Each party owns what they themselves bought or earned. There is no community of property.
- Inheritance: Unmarried cohabitants do not inherit automatically. You must make a will to leave assets to your partner.
- Estate duty: If you inherit via a will, the estate-duty rate for cohabitants is 36.25% — far higher than the 0% that applies between spouses. After 2 years of cohabitation the rate falls to 15%.
- Pensions: Many pension schemes allow you to name an unmarried cohabitant as beneficiary — but you must actively register this.
- Housing: An unmarried cohabitant has no automatic right to stay in a rented home if the other party moves out or dies — the lease is only in the tenant's name.
When does it apply?
- You live with a partner without being married.
- You are planning finances, a property purchase or children as unmarried cohabitants.
What to do if you live with your partner without being married in Denmark
- Make a cohabitation agreement covering property, expenses and what should happen if you separate.
- Make a will — without a will your partner inherits nothing.
- Register your partner as a pension beneficiary with your pension company.
- Consider co-ownership agreements when buying property.
What should you NOT do?
- Don't assume you have the same rights as spouses — you have almost none in any area of law.
- Don't buy real estate together without a written agreement — disputes over ownership are common and expensive to resolve without documentation.
- Don't forget the difference in estate duty — without the 2-year rule the duty rate is heavy.
About Family Law in Denmark
Most family-law cases in Denmark start at Familieretshuset (the Agency of Family Law), the central authority that since 2019 has handled divorce, custody, child support and paternity. You can be divorced administratively if you agree, or via the family court if you do not. Couples with children under 18 go through a 3-month reflection period. Forældreansvarsloven (the Parental Responsibility Act) treats joint custody as the default and applies the best interests of the child; children from age 10 have the right to be heard. Domestic violence is handled through restraining orders and the rules of the Criminal Code.
