Prenuptial Agreements in Germany: How an Ehevertrag Protects Spouses’ Assets

A prenuptial agreement in Germany is not only for couples with substantial assets. If spouses do not enter into an Ehevertrag, the statutory property regime of Zugewinngemeinschaft automatically applies. It does not turn all purchases and income into joint property, but on divorce or another end of the regime it can lead to an equalization of gains in the spouses’ assets.

What Happens Without a Prenuptial Agreement

By default, spouses in Germany live under the Zugewinngemeinschaft regime. This is often translated as “community of accrued gains,” but it is important to understand the nuance: each spouse’s property remains their own. Marriage alone does not automatically create joint ownership of a salary, bank account, apartment, or business.

The main mechanism applies later. When the property regime ends, for example through divorce, each spouse’s initial and final assets are compared. If one spouse increased their assets more than the other during the marriage, half of the difference in the gains may become a claim of the other spouse.

A simple example: one spouse has saved and invested substantially more during the marriage, while the other’s assets have grown less. In this situation, it is not about “half of the salary” or transferring all assets, but about monetary Zugewinnausgleich—the equalization of gains.

What Is Usually Not Divided Directly

Under the statutory regime, it is important to distinguish ownership from gains. Not everything becomes part of a “common pot” before a settlement.

The following are usually considered separately:

• property each person owned before the marriage;
• personal gifts and inheritances, if they are properly reflected in the calculations;
• each spouse’s personal debts and obligations;
• assets that legally belong to only one spouse.

However, an increase in the value of such assets can matter. For example, if a business, company shareholding, securities portfolio, or property rises significantly in value during the marriage, that gain may be included in the Zugewinnausgleich calculation. This is why entrepreneurs, freelancers, investors, and property owners should understand the consequences in advance.

When an Ehevertrag Is Especially Useful

A prenuptial agreement helps establish rules in advance that better suit a particular family. It is not necessarily an “agreement of distrust.” At its best, it is a financial map for difficult life scenarios: a business, relocation, parental leave, childcare, income differences, or an international marriage.

An Ehevertrag is often considered when:

• one or both spouses run a business, freelance practice, or own shares in a company;
• the couple has a substantial difference in income or capital;
• one spouse plans to take Elternzeit or a long break from work for the family;
• there is property, investments, family assets, or an expected inheritance;
• the spouses are connected to different countries, nationalities, or legal systems;
• the couple wants to reduce the risk of a lengthy property dispute in the event of divorce.

What Can Be Regulated in a Prenuptial Agreement

In Germany, a prenuptial agreement can change the property regime and clarify individual consequences of marriage. In practice, different models are used.

The most common options are:

• Gütertrennung — separation of property without the standard equalization of gains;
• modifizierte Zugewinngemeinschaft — the statutory regime remains, but certain assets or situations are treated differently;
• rules for a business, company shares, property, and investments;
• compensation for a spouse who temporarily reduces their income because of children or family;
• arrangements for individual maintenance issues within the limits of the law;
• procedures for valuing assets and settling disputes, including mediation.

Not everything can be agreed freely. German law protects the weaker party to the agreement, children, and fundamental family obligations. Clearly one-sided terms or terms that violate mandatory rules may be challenged.

Why a Notary Is Required

An Ehevertrag in Germany must be concluded before a notary with both parties present at the same time. A simple written agreement between spouses is not sufficient for this type of contract.

A notary does not merely “put a stamp on it.” They prepare the agreement in the required form, explain the legal consequences, and ensure the parties understand what they are signing. If the circumstances are complex—business, international law, substantial assets, children from different marriages, or tax consequences—it is worth discussing the draft separately with a family-law lawyer or tax adviser before seeing the notary.

How Much a Prenuptial Agreement Costs

There is no universal fixed price. Notarial costs in Germany depend on the Geschäftswert—the assessed value of the matter under the rules of the Gerichts- und Notarkostengesetz. For an Ehevertrag, the spouses’ current assets are usually considered; where the agreement covers only particular assets, the value of those assets or claims is used.

That is why a short statement such as “an agreement costs from €400 to €2,000” can be misleading. Costs will differ for a couple without significant assets and for an entrepreneur with a company or property. There may also be additional costs for legal advice, translation, tax valuation, or an expert assessment of assets.

Can You Conclude an Agreement After the Wedding?

Yes, an Ehevertrag can also be concluded after the marriage is registered. However, both spouses must agree. The closer a conflict or divorce is, the harder it is to reach an agreement, because each party is already assessing what they gain or lose if the current regime remains in place.

In practical terms, it is better to discuss an agreement before the wedding or during a calm period of the marriage: when buying property, starting a business, having a child, moving to Germany, or when income changes significantly.

What to Check Before Signing

Before meeting the notary, it is useful to prepare the facts without which the agreement will be superficial.

Check:

• what property each person owned before the marriage;
• what assets appeared during the marriage;
• whether there is a business, shareholdings, options, investments, or property;
• what loans and personal obligations each person has;
• whether children, Elternzeit, or a move to another country are planned;
• whether inheritances, gifts, or family assets need to be considered;
• whether an interpreter or advice on another country’s law will be needed.

Common Mistakes

The most dangerous mistake is thinking that there is “nothing to divide” without a prenuptial agreement if accounts and property are held separately. In Germany, separate ownership and equalization of gains are different things.

The second mistake is excluding from the agreement only what exists today. For an entrepreneur, the future growth of a business is often more important than its current value.

The third mistake is signing a rigid template without considering children, periods spent caring for the family, and one spouse’s financial dependence. Such an agreement can become a source of a new dispute rather than protection.

Brief Conclusion

A prenuptial agreement in Germany is useful when the standard Zugewinngemeinschaft regime does not reflect a couple’s real plans. It is especially important for entrepreneurs, freelancers, property owners, international families, and spouses with different financial roles in the marriage. But the agreement must be balanced, notarized, and understood by both parties; otherwise, it will not solve the problem and will only push the conflict into the future.
