What can you decide in a prenuptial agreement?

Spouses-to-be may decide that property that belongs to or later accrues to either of them shall be that person's separate property. The prenuptial agreement can cover all property, only one party's property, or specifically defined property.

This template is primarily designed for complete or unilateral separation of property before the wedding. If only a certain company, a specific property, an account, or another specifically identified asset is to be separate property, a more specifically defined template is often more appropriate.

Marital property is not the same as joint ownership

A prenuptial agreement does not change who owns an asset during the marriage. Marital rights become significant primarily in the event of a division of marital property.

It is therefore misleading to say that "all property is divided equally" without a prenuptial agreement. As a general rule, the spouses' marital property is included in a division of property; debts are deducted, and the net value is then divided according to the rules of the law. Furthermore, property may already be separate property on other grounds, such as through a gift or a will with conditions regarding separate property.

Surrogates – property replacing separate property

As a general rule, what replaces separate property is also separate property, unless otherwise stipulated. This could be, for example, a new asset purchased with money from the sale of a separate property asset.

The template makes this clear and also provides the option to specify exceptions.

Yields – an important distinction

Conversely, the yield from separate property is, according to the main rule of the law, marital property, unless otherwise stipulated in the legal act that made the property separate.

This may apply to, for example, dividends, interest, and rental income. The new template therefore forces an active choice between the yield also being separate property or the law's main rule applying.

Future property

The Marriage Code makes it possible for the prenuptial agreement to cover property that a party already owns and property that later accrues to the party. Therefore, the template contains options for both current and future property.

Ownership rights and debts do not change automatically

A prenuptial agreement does not transfer ownership of the house, the company, securities, or other assets between the parties. Nor does it make one party liable for the other's debts.

If ownership is to be changed, a separate civil law transfer is required, such as a purchase, gift, or other relevant deed.

A prenuptial agreement does not determine who inherits

The prenuptial agreement affects what is separate property and marital property during a division of property, but it does not regulate who inherits from a spouse. Inheritance planning may therefore require a will.

Registration with the Swedish Tax Agency

To have legal effect according to the rules on prenuptial agreements, the document must be registered with the Swedish Tax Agency.

• The original document must be sent to Skatteverket, Äktenskapsregistret, 871 87 Härnösand.
• Both parties must have signed and dated the document.
• Personal identity numbers should be provided so that the parties can be identified.
• The Swedish Tax Agency's current application fee as of October 6, 2026, is 275 SEK per registration case.
• After registration, the Swedish Tax Agency sends back the original and archives a copy.

When does a prenuptial agreement before marriage take effect?

If a prenuptial agreement between spouses-to-be is submitted for registration no later than one month after the wedding, it is valid from the date the marriage was entered into.

If it is submitted later, it does not have retroactive effect from the wedding day. After the wedding, the parties are treated as spouses, and the effect of the agreement is linked to when the document is received by the Swedish Tax Agency.

Registration is not a material quality check

The Swedish Tax Agency mainly checks the formal requirements for registration. Registration does not mean that the authority has determined that the agreement is materially valid, fair, or has the exact legal effect the parties intended.

Avoid time limits and conditions

The Swedish Tax Agency's legal guidance indicates that spouses cannot time-limit or condition a prenuptial agreement in the way that sometimes occurs in private agreements. If the parties later wish to change the property arrangement, they should instead draw up and register a new prenuptial agreement.

Can a prenuptial agreement be changed?

Yes. A new prenuptial agreement can, for example, stipulate that property that was previously made separate property is to be marital property again. The new document must meet the same formal and registration requirements.

Unreasonable conditions

According to Chapter 12, Section 3 of the Marriage Code, a condition in a prenuptial agreement may in certain cases be adjusted or disregarded in the event of a division of property if the condition is unreasonable in view of, among other things, the content of the agreement, the circumstances at the time of its creation, and subsequently occurring circumstances.

It is therefore inappropriate to describe a registered prenuptial agreement as an absolute guarantee of a certain future financial outcome.

International connection

If either party has foreign citizenship, lives abroad, owns property in another country, or plans to move, EU rules on matrimonial property regimes and Swedish private international law may affect the choice of law, form, and effect.

In such cases, individual legal advice is recommended.

Frequently asked questions

Must a prenuptial agreement be witnessed?

No. Witnesses are not included in the statutory formal requirements for prenuptial agreements.

Must the prenuptial agreement be registered?

Yes. A prenuptial agreement must be registered with the Swedish Tax Agency.

Can we make all future property separate property?

Yes, prenuptial agreements can cover property that a party currently owns or that later accrues to the party. The wording should be clear.

Does a dividend from separate shares automatically become separate property?

No. According to the main rule, the yield from separate property is marital property unless otherwise stipulated.

Can we write that the prenuptial agreement only applies for five years?

That should not be done. The Swedish Tax Agency's legal guidance indicates that prenuptial agreements cannot be time-limited in that way. If you want to change the arrangement later, a new prenuptial agreement should be drawn up and registered.

Does registration guarantee that the content works exactly as intended?

No. The Swedish Tax Agency does not perform a full material review of the legal effects of the agreement upon registration.

This package is a general documentation support according to Swedish law and does not replace individual legal advice.
