Important correction: witnesses are not required
The older product placed unnecessary emphasis on witness signatures. Under Chapter 7 section 3 of the Swedish Marriage Code, a prenuptial agreement must be in writing, dated, signed by both prospective spouses and registered with the Swedish Tax Agency.
Witnesses are not a statutory form requirement. They may be used voluntarily for evidentiary purposes, but they do not replace the parties' signatures or registration.
What can a Swedish prenuptial agreement do?
Prospective spouses can agree that property already owned by either of them, or property acquired later, shall be that spouse's separate property. The arrangement can cover all property, only one spouse's property or selected property.
This package is primarily designed for full or one-sided separation of property before marriage. If only a specific company, property, account or other identified asset should be separate, a more narrowly drafted agreement is generally more suitable.
Marital property does not mean co-ownership
A Swedish prenuptial agreement does not change who legally owns an asset during the marriage. The distinction between marital property and separate property mainly affects a future division of property.
It is therefore inaccurate to say that “all property is divided equally” when there is no prenuptial agreement. In a Swedish division of property, marital property is generally included, liabilities are deducted and the remaining net amount is divided according to the statutory rules. Some property can already be separate on another legal basis, such as a gift or will containing a separate-property condition.
Substitute property
Under Chapter 7 section 2 of the Swedish Marriage Code, property replacing separate property is generally also separate property unless otherwise provided by the legal instrument that made the original property separate.
The template makes this rule explicit and allows the parties to record an exception where appropriate.
Yield and income from separate property
This is one of the most important drafting points. Under the Swedish statutory default, yield from separate property is marital property unless the relevant legal instrument provides otherwise.
This can include dividends, interest, rental income and other recurring returns. The template therefore requires the parties to make an express choice on whether yield should also be separate property.
Future property
The Swedish Marriage Code permits a prenuptial agreement to cover property that a spouse already owns as well as property that later accrues to that spouse. The template includes options for current and future property.
Ownership and liabilities are not automatically transferred
A prenuptial agreement does not transfer legal ownership of a house, company, securities or bank account between the spouses. Nor does it make one spouse responsible for the other's liabilities.
If ownership is to change, a separate legally appropriate transfer – for example a purchase or gift – may be required.
A prenuptial agreement does not determine inheritance
The agreement affects the classification of property for division of property. It does not decide who inherits after a spouse dies. Inheritance planning can therefore require a separate will.
Registration with the Swedish Tax Agency
Registration is required for the agreement to obtain the legal effect prescribed by the Swedish Marriage Code.
- The signed original is sent to Skatteverket, Äktenskapsregistret, 871 87 Härnösand, Sweden.
- Both parties should sign and date the document.
- Swedish personal identity numbers should be stated where available so the parties can be identified.
- The Swedish Tax Agency's current application fee on 7 October 2026 is SEK 275 per registration matter.
- After registration, the Tax Agency returns the original and retains an electronic copy.
When does a premarital agreement take effect?
If an agreement executed before the wedding is submitted for registration no later than one month after the marriage date, it takes effect from the date of marriage.
If it is submitted later, it does not receive retroactive effect from the wedding date. After the marriage has taken place, the rules applicable to spouses govern the effective date.
Registration is not substantive legal approval
The Swedish Tax Agency checks the formal conditions for registration. Registration does not mean that the authority has decided that the wording is fair, materially valid or will necessarily produce every legal consequence the parties expect.
Avoid time limits and conditional clauses
Swedish Tax Agency guidance states that a prenuptial agreement cannot simply be structured as a private contract that expires after a set number of years or depends on uncertain future conditions. If the spouses later want to change the property regime, they should execute and register a new prenuptial agreement.
Later changes
A new registered prenuptial agreement can, for example, convert property that was previously made separate property back into marital property. The new document must satisfy the applicable form and registration requirements.
Unreasonable terms
Under Chapter 12 section 3 of the Swedish Marriage Code, a term in a prenuptial agreement can in certain circumstances be adjusted or disregarded on division of property if it would be unreasonable having regard to the content, circumstances at formation, later developments and the circumstances overall.
A registered agreement should therefore not be presented as an absolute guarantee of a particular future financial result.
Cross-border situations
Foreign nationality, residence outside Sweden, property in another country or a planned international move can raise additional choice-of-law and form questions under EU Regulation 2016/1103 and Swedish private international law. Individual legal advice is recommended in such cases.
English primary – Swedish reference included
The English document is the primary template in this product. A full Swedish reference version is included separately.
This is not a UK or US prenuptial agreement. English terminology is used to make the documents easier to work with internationally, but the governing legal framework is Swedish.

Frequently asked questions
Do we need witnesses?
No. Witnesses are not part of the statutory Swedish form requirements for a prenuptial agreement.
Must the agreement be registered?
Yes. A Swedish prenuptial agreement must be registered with the Swedish Tax Agency.
Can future property be made separate?
Yes. The agreement can cover property already owned and property that later accrues to a spouse, provided the drafting is sufficiently clear.
Are dividends from separate shares automatically separate property?
No. Under the statutory default, yield from separate property is marital property unless otherwise provided.
Can the agreement say that it expires after five years?
That structure should be avoided. Swedish guidance does not treat a prenuptial agreement as an ordinary time-limited private contract. A later change should instead be made through a new registered agreement.
Does registration guarantee that the agreement will work exactly as intended?
No. Registration is not a complete substantive review of fairness, interpretation or future legal effect.
This package is a general documentation aid governed by Swedish law and does not replace individual legal advice.
