Determination of the Law Applicable to German-American Estate Matters

Under the European Succession Regulation, the conflict of laws rules regarding succession matters applied by Germany have changed dramatically for decedents with a date of death occurring on or after August 17, 2015. While U.S. laws regarding the determination of the laws applicable to probate estates and trusts haven’t changed, the European Succession Regulation may have a significant impact on the law to be applied by U.S. courts. This article outlines the law applicable to US/German estate matters from a German and U.S. perspective.

Applicable Law from a German Perspective

A German court will determine the applicable law for deaths occurring on or after August 17, 2015, under the European Succession Regulation (‘the Regulation’).

Notably, a German court will apply the Regulation whether it is the law of a Member State of the Regulation or not.[1] Accordingly, German courts will also apply the Regulation in relation to estates of persons domiciled in the U.S. or estates with U.S. real estate. This broad application is consequential as it could result in the application of German law even when a U.S. court would typically apply U.S. law. 

The application of the Regulation is broad. The Regulation applies to all questions pertaining to “succession to the estates of deceased persons”.[2] ‘Succession’ means succession to the estate of a deceased person and covers all forms of transfer of assets, rights, and obligations by reason of death, whether by way of a voluntary transfer under a disposition of property upon death or a transfer through intestate succession. However,

Application to Trusts and Other Non-Probate Transfers

Some questions that typically arise in US/German estate/trust matters are excluded from the scope of the Regulation; in particular, the Regulation does not apply to 

  • the “creation, administration and dissolution of trusts”. However, this should not be understood as a general exclusion of trusts; e.g. where a trust is created under a will (testamentary trust) or under statute in connection with intestate succession, the law applicable to the succession under the Regulation should apply with respect to the devolution of the assets and the determination of the beneficiaries.[3] The Regulation does not state which law applies with regard to the creation of a living trust and the administration and dissolution of trusts. As Germany is not a member of the Hague Convention on the Law Applicable to Trusts and on their Recognition, a German court will determine the applicable law under domestic conflict of law rules, specifically, Art. 25 Introductory Act to the Civil Code (EBGB).
  • non-probate transfers on death, e.g.,  by way of gifts, joint ownership with a right of survivorship or a pension plan. 
  • questions relating to matrimonial property regimes and property regimes of relationships deemed by the law applicable to such relationships to have comparable effects to marriage.

However, any obligation to restore or account for gifts (e.g., “clawback”), when determining the forced heirship right, is in the scope of the Regulation even when a non-probate instrument or a trust is utilized.

Example: Norbert`s domicile, residence, and habitual abode are in Germany. He and his daughter own a bank account with a Bank in Florida, which is held in joint tenancy. While the laws of Florida govern the question of whether the bank may pay out to his daughter after his passing, German law is applicable regarding the question if his other children have a clawback claim. 

General Rule and Last Habitual Residence

Generally, the law applicable to succession matters is governed by the law of the State in which the decedent had his habitual residence (gewöhnlicher Aufenthalt) at the time of death.[4]

A threshold issue that has created uncertainty is that the term ‘last habitual residence’ is not defined in the Regulation. In order to determine the habitual residence, a German court will make an overall assessment of the circumstances of the life of the deceased during the years preceding his death and at the time of his death.[5] The court will take into account all relevant factual elements, including:

  • The duration and regularity of the decedent’s presence in the U.S. or in Germany;
  • the conditions and reasons for that presence; and
  • the individual’s intent to remain in the country for an indefinite period or not.

Please note: While an individual’s intent is relevant to the overall assessment, a new habitual residence does not require that the decedent intends to remain for an indefinite period with no definitive intention of returning. Therefore, the habitual residence of a person may be different from that person’s “domicile”.

While the duration and regularity of the decedent’s presence in the U.S. or in Germany is relevant, no minimum period is required for the establishment of a new habitual residence.[6]

Example: Wolfgang moves from Germany to Boston, MA, on March 20, 2025, and abandons his home in Munich, Germany. On April 10th, Wolfgang died in a car accident. Based on the given fact, Wolfgang`s “habitual residence” would be considered to be in Massachusetts. 

A decedent who maintained a close and stable connection with his home country, but was required to live abroad for professional reasons, even for a significant period of time, could still be considered to have his habitual residence in his State of origin, in which the center of interests of his family and his social life was located.[7]

Continuation of Example: If in the example above the decedent worked for a German subsidiary of Siemens, his family stayed in Germany, and he visited them on occasion. Germany would apply German law as the decedent maintained a stable connection to Germany.

In the case of a decedent who lived in several States alternately or travelled from one State to another without settling permanently in any of them, his nationality or the location of his main assets will be a significant factor in determining his habitual residence.[8]

Immovables

While the conflict of law rules in force until August 16, 2015, included an exception for immovables (e.g., real estate) in the U.S., there is no such exception under the European Succession Regulation, and the law determined as outlined in this article also governs succession with regard to immovable assets located in the U.S. However, U.S. courts are likely to disregard the application of German law to the disposition of immovable property in the U.S.. As a result, German and U.S. courts may apply different laws.

Example: Axel, a German citizen purchases a vacation home in Naples, Florida, which he uses every summer. His family and center of interest are in Germany. He dies intestate. Based on the situs of the real property, a Florida court will apply Florida law to the disposition of the vacation home, whereas a German court will apply German law.

In such a scenario, the German court, having ceased to rule on the succession, may, at the request of one of the parties, decide not to rule on one or more of such assets as it may be expected that its decision in respect of the U.S. assets will not be recognized.[19] Arguably, this does not apply to forced heirship claims as such claims may be enforceable in assets located in Germany or other States that would recognize a German judgment.

Renvoi

When the law determined under article 21(1) is the law of any non-member State of the Regulation (e.g., the U.S.), article 34(1) holds that such State’s rules of conflict of laws are included insofar as those rules refer back to the law of a Member State. Accordingly, referrals to German law by U.S. conflict of laws rules are to be observed, and the German substantive provisions shall apply. This is particularly relevant with regard to immovable property (e.g., real estate) situated in Germany of a decedent having his/her last habitual residence (and domicile) in the U.S.

Example: David, a US citizen having his last habitual residence in the U.S. and domiciled in Illinois, dies without leaving a will. His estate includes an apartment in Berlin, Germany. Art. 21(1) of the Succession Regulation refers to U.S. law. As Illinois law calls for the application of the law of the situs of immovables, German courts would apply German law with regard to the apartment in Germany by way of back reference from Illinois law. 

But even in the rather rare cases where habitual residence and domicile fall apart, there can be a referral to German law.

Example: In 2014, Monika, a German citizen, moved to Virginia together with her family. She then died in 2015. However, the family always expressed the clear intention to return to Germany after his retirement. A German court would apply German law by way of back reference from Virginia law, whereas a court in Virginia would apply the laws of Virginia. 

Applicable Partial Legal Order

When the Regulation refers to U.S. law, a court must determine which partial legal order is applicable. According to Article 36(1) of the Regulation, the relevant jurisdiction is primarily determined by the internal conflict of laws rules of the respective State. In the U.S., the vast majority of inheritance matters are not subject to federal subject matter jurisdiction, and there is no federal probate code. Instead, probate and trust matters are generally subject to state law.[9] Thus, the law of the U.S. state in which the decedent had his habitual residence at the time of death is applicable.[10]

“Escape Clause”

Article 21(2) provides for an exception from the general rule in article 21(1). The exception applies when it is clear from all the circumstances of the case that, at the time of death, the decedent was manifestly more closely connected with a State other than the State where he had his habitual residence. In this case, the law applicable to the succession shall be the law of that State.

Article 21(2) is intended to apply in exceptional cases. For example, if a decedent was to move from the State of his habitual residence just before his death and all the circumstances of the case indicate that he was manifestly more closely connected with another State.[11] Another example would be if an incapacitated individual whose guardian relocates from Germany to the U.S. without his wish, and later dies in the U.S.

The mere fact that it is difficult to determine the habitual residence of the decedent, is not a sufficient justification for the application of article 21(2)[12], and there must be a compelling argument that the decedent was closely connected with the State.

Choice of Law Clauses

Pursuant to article 22(1), the testator may choose the law applicable to their “succession as a whole”. The choice of law can include the law of the State whose nationality he possesses:

  • at the time of making the choice or
  • at the time of death.

If an individual possesses multiple nationalities, they may choose the law of any of the States whose nationality they possess at the time the election is made or at the time of death.

The choice can be made expressly in a declaration in the form of a disposition of property upon death (e.g., a will) or it shall be demonstrated by the terms of such a disposition (implied choice of law).[13] For example, a choice of law can be demonstrated by a disposition of property upon death where the decedent referred in his disposition to specific provisions of the law of the State of his nationality or where he had otherwise mentioned that law.[14]

Example: Albert, a U.S. citizen from Connecticut, permanently lives in Berlin, Germany. Albert makes a will attested by 2 witnesses in the U.S. Embassy in English in which he names his cousin in Hartford as “personal representative” and devises his “residuary estate” to this niece. A Will of this sort is typical for common law jurisdictions, but not for Germany. Accordingly, an implied choice of the laws of Connecticut be inferred from the will. 

A choice of law is only permissible if it pertains to the entire estate of the decedent. A choice of law with regard to particular assets or assets located in a particular jurisdiction will be deemed void.

Please note: It is common in US/German estate plans to make separate wills for assets located within each jurisdiction, and the wills typically limit their applicability to assets located within the specific jurisdiction. However, when the testator limits the application of laws to specific assets, such an estate plan may result in an unacceptable partial election. 

In case of a choice of law election, the substantive provisions of the chosen law are applicable. The conflict of laws rules of the appointed State are irrelevant because a renvoi is not applied.[15]

 When a U.S. citizen with a habitual residence in Germany chooses “U.S. law”, the inheritance law of the U.S. state in which the decedent had the closest connection shall apply.[16] If the testator chooses the law of a particular U.S. state and he is not most closely connected to this state, the choice of law is generally invalid.

Deemed Choice of Law 

If a disposition of property upon death was made prior to August 17, 2015, in accordance with the decedent's chosen law according to the Regulation, that law shall be deemed to have been chosen as the law applicable to the succession.

Example: A German citizen dies in 2016 with a habitual residence in California. In 2010, he had made a notarized will before a German notary and designated an “heir” without naming a “personal representative”. As such a will is typical for Germany but rather uncommon in California, it is deemed that he has chosen German law to govern succession.

Public Policy 

The application of a provision of the law of any State specified by the Regulation may be refused only if such application is manifestly incompatible with the public policy (ordre public) of the forum.

If a U.S. citizen from California uses a choice of law clause in order to avoid Germany’s forced heirship regime, the question arises if the application of Californian Law is incompatible with the German public policy (ordre public). Forced heirs may argue, that the German Federal Constitutional Court (Bundesverfassungsgericht)[17] provides that the German forced heirship regime receives constitutional status.[18] However, a counterargument to such an assessment is that the legislators of the Regulation recognized that the choice of law can be used to avoid the compulsory share, and they decided to limit its applicability only to the law of the decedent’s nationality.

Special Rules

Special rules apply with regard to the admissibility (e.g., joint wills) and substantive validity (e.g., capacity or interpretation of a will) of dispositions of property upon death; insofar that it must be based on the date of the establishment.[20] In addition, there are special rules with regard to the admissibility, substantive validity, and binding effects of agreements as to succession;[21] such rules also apply to a contract to make a will or not to make a will. Finally, there are special rules with regard to the formal validity of a will, which is governed by the Hague Convention.[22]

Applicable Law from the Perspective of a U.S. Court

There is no federal conflict of laws regarding the determination of law applicable to US/German estate or trust matters. In all States, the conflict of laws analysis begins by applying a basic formula that holds that

  • The law of the domicile applies to “movable” property, and
  • the law of the situs applies to dispositions of “immovable” property.

However, different rules apply with regard to the validity of a will as regards to form, and the administration of estates and trusts.

Movable Property

As stated above, the law of the domicile applies to “movable” property.[23] 

While there is no uniform definition of domicile, domicile consists of two elements that must exist concurrently:

  • physical presence in the jurisdiction and
  • the intent to remain indefinitely.[24]

This common law definition has been codified in one form or another in both federal and state laws. For example, under New York law, “domicile” is defined as “a fixed, permanent and principal home to which a person wherever temporarily located always intends to return."[25] 

Pursuant to this test, a person may have only one domicile at a given time. [26]

Immovable Property

With respect to immovable property located in the U.S., U.S. courts are likely to apply U.S. law regardless of the decedent’s domicile.[27] The characterization of an asset as movable or immovable is governed by the law of the situs.[28] Thus, German law would apply to the characterization of assets located within Germany, whereas U.S. law would apply to U.S. situs assets.

Example: The decedent dies with last habitual residence and domicile in New York without a Will. He owned real estate in Berlin held in a German partnership. As Germany generally characterizes real estate held via a partnership as movables.[29] Accordingly, New York laws would govern the distribution of the interest in the German assets.  

Administration of the Estate

The administration of a decedent’s estate is governed by the local law of the state that has appointed the personal representative (lex fori).[30] It is important to consider that it is possible that multiple states have jurisdiction because jurisdiction exists both in the state in which the testator had his last domicile, as well as in a situs-state of immovable property.[31] When an individual dies owning real property (not subject to a trust), that real property is subject to the jurisdiction of the Court in the County where the property is located.  As seen above, movable (or intangible) assets can be subject to ancillary proceedings out of state or even in foreign jurisdictions. Accordingly, the characterization of an asset as immovable or movable can be a threshold issue in determining jurisdiction, which will govern the application of U.S. probate administration law.[32]

Accepting a Choice of Law Clause under the Regulation

As stated above, under German law, the testator may choose the law of his/her nationality according to Art. 22 of the Regulation. The ability to undertake this election is significant, as the choice of law selection could negate the German forced share. In contrast, most States do not allow or partially allow a choice of law. A question thus arises whether a choice of law clause that touches on substantive issues (other than interpretation) will be recognized in the U.S.  

If the decedent was domiciled in Germany at the time when he/she made the choice of law or at the time of his/her death, such choice of law will likely be honored by U.S. probate courts as the choice of law rules of the U.S. refer not only to German internal law but to Germany’s choice of law rules.[33]  As far as a U.S. citizen has elected “U.S. law” with regard to immovables in Germany, the same holds true.[34]
