Recognition of Foreign Wills in Germany: Why It Matters for U.S. Citizens

Your Will, Recognized. Your Legacy, Protected

I guide clients through the recognition of U.S. and other foreign wills in Germany—securely, efficiently, and without costly mistakes.

Recognition of foreign wills is not a mere formality. It determines whether your wishes will actually be enforced under German law. If your will fails recognition, statutory succession rules apply—potentially giving shares of your estate to relatives you never intended to benefit. Executors named in a U.S. will may be blocked from acting, German banks may freeze accounts, and property transfers may stall for years. Recognition ensures your legacy is preserved exactly as you intended, even across borders.

Why Recognition Matters

Wills made abroad—such as under U.S. law—are not automatically valid in Germany. Recognition depends on compliance with the European Succession Regulation and other international rules. According to the Hague Convention on the Form of Wills, a will is considered formally valid in Germany if it complies with:

• The law of the state where it was executed
• The law of the testator’s nationality
• The law of the place of the testator’s last residence or habitual abode
• Or, in the case of real estate, the law of the state where the property is located

Formal Validity vs. Material Validity

Recognition requires distinguishing between two issues:

• Formal Validity: Is the will properly executed (e.g., handwritten, notarized, or in the required form)?
• Material Validity: Are the substantive provisions enforceable? This depends on the so-called hypothetical succession law, i.e., the law of the habitual residence at the time the will was made. The testator may also choose the law of their nationality.

For inheritance contracts (Erbverträge), stricter rules apply: validity depends exclusively on the hypothetical succession law, and no choice of law is possible.

Special Case: Joint Wills (Ehegattentestamente)

Recognition of joint wills—such as the German Berliner Testament—is particularly problematic in international cases. Some countries (including Italy, Greece, and Portugal) do not recognize joint wills at all, viewing them as a violation of public policy (ordre public). For U.S. citizens with German assets, this means extreme caution is required when using joint wills in cross-border situations.

Risks of Non-Recognition

• German authorities, banks, or land registries may refuse to execute the will
• Probate proceedings become delayed and more expensive
• Statutory or compulsory-share (Pflichtteil) claims may override your intent
• Executors appointed abroad may lack authority in Germany
• Assets may remain frozen or pass to unintended heirs

Requirements for Recognition

To ensure a foreign will is recognized in Germany:

• Confirm formal validity under one of the accepted laws
• Include a clear choice-of-law clause
• Provide official translations and authentication (apostille)
• File the will with the competent German probate court or via a German consulate
• Anticipate scrutiny of trusts, joint wills, or ambiguous language

Practical Scenarios

• U.S. Citizens Owning German Property: Real estate in Germany must pass through German probate, regardless of a U.S. will
• German Citizens Living in the U.S.: Their German assets remain subject to German succession law
• Dual Citizens: Must comply with both systems—double compliance is key
• Executors Named Abroad: Without recognition, executors lack standing before German institutions

Mistakes to Avoid

• Ignoring the governing law clause—leads to unintended application of German law
• Using informal wills for complex estates—high risk of rejection
• Assuming U.S. trusts are automatically valid in Germany—they are not
• Filing too late—delays freeze assets and increase disputes
• Skipping legal review—minor defects can void an entire will

Strategic Considerations for Cross-Border Families

Recognition is more than a box-ticking exercise—it is the hinge on which international estate planning turns. Families with property in several jurisdictions must carefully coordinate their documents to ensure consistency. A U.S. will that contradicts a German inheritance contract, or a German joint will that is not enforceable abroad, can create conflicts that leave heirs tied up in litigation for years. Proper recognition planning means aligning documents, anticipating conflicts of law, and ensuring every will or contract is compatible across jurisdictions.
