Determining Heirs in the Tension Between Formal Wills and Informal Amendments
The recent decision of the Federal Court of Justice (Bundesgerichtshof, BGH, decision of January 10, 2024 – IV ZB 30/20) once again puts the requirements for the formal validity of testamentary dispositions at the center of the discourse on inheritance law. For entrepreneurial testators, investors, and wealthy private individuals, the question often arises as to how binding inheritances formulated in a handwritten will can be modified by subsequent documents that are not created in a formally valid manner. With its decision, the BGH has laid out clear guidelines on the conditions under which amendments outside the statutory will form can affect determinations of heirs—and when the validity of such amendments fails.
The Legal Situation: Relevance of Will Form
According to German inheritance law (§ 2247 BGB), a handwritten will requires the strict adherence to certain formal provisions. The assumption that additional, informally created amendments—such as handwritten notes, annexes, or unsigned lists—could potentially correct or individualize an already made determination of heirs in a properly executed will has now been explicitly rejected by the BGH.
Will Form as a Prerequisite for Validity
Federal law stipulates that expressly intended dispositions of last will only have legal effect if they have been made in a formally valid manner. Violations of form carry the risk that subsequent individualizations, such as the final naming of specific individuals from a group mentioned in the will, remain ineffective. This means that testators must carefully examine whether intended changes or additions meet the strict form requirements of inheritance law when designing wills.
The Federal Court of Justice’s Decision: Background and Implications
Case Scenario: Group Inheritance with Subsequent Assignment
In the specific case, the testator in the holographic will named the “descendants of my siblings” as heirs, which initially provides a relatively indeterminate basis for disposition without further individualization. Later, a separate list that was not personally signed and dated was attached to the will, listing the descendants by name. The heir claimants based their appeals on the formal and material requirements for validity.
Legal Evaluation: Formal Defect Leads to Invalidity
The BGH confirmed that a group designation in the will, combined with subsequent individualization carried out through non-will-compliant lists, does not meet the legal requirements. This listing, according to the BGH, constitutes an impermissible delegative concretization of heirs that, in its present form, cannot entail any binding effect. The formally invalid announcement of named heirs does not preserve the necessary authenticity and integrity of the testamentary disposition.
Principle: Group Designation and Individualization Must Meet the Same Formality Requirements
The Federal Court of Justice sees this as a principle whose observance is of significant importance, particularly in complex inheritance successions—such as in family corporations, multi-generation wealth, or company holdings: The identification of heirs must be unequivocally possible at any time through the properly executed will. If there is a lack of this clarity, the probate court cannot issue a certificate of inheritance due to the absence of a clear determination of heirs. This increases the risk of adverse legal uncertainties and costly inheritance disputes.
Practical Relevance for Businesses, Investors, and Wealthy Individuals
Risk Areas in Amendments and Attachments
For individuals with complex asset structures, who—due to reasons of discretion or flexibility—regularly resort to supplemental amendments, the BGH’s decision is of fundamental relevance. There is often a need to later concretize an abstract group designation in the will through new, current lists or notifications. However, the decision makes it clear: Such formally invalid amendments do not have legal effect. In fact, referencing lists created only afterwards may even endanger the effectiveness of the entire determination of heirs.
Impact on Will Design
Particularly in entrepreneurial structures, but also in family offices or foundation models, the ability to design flexible succession arrangements is practically significant. The BGH’s jurisprudence requires that any testamentary individualization, whether through name lists, distribution plans, or group-specific assignments, must be made through the formally valid will itself. Subsequent modifications that circumvent these formality requirements generally lead to invalidity.
Significance for the Design of Corporate and Wealth Succession
The decision underscores the necessity to make all aspects of wealth succession—from the selection and determination of heirs to the specific allocation of individual estate values—in compliance with legal requirements. Especially for entrepreneurial successions, where corporate law commitments as well as complex participation and exclusion mechanisms play a role, precise and form-compliant execution of testamentary dispositions is essential.
Legal Certainty Through Strict Formal Design
The BGH’s decision leads to an increased formal quality threshold in the design of wills and amendments. Especially internationally active companies or investors, whose wealth succession often involves multinational components, must maintain the strict requirements of German inheritance law on determinability and form. A lack of individualization in the prescribed form can result in significant uncertainties and potential disputes regarding the succession.
Testator’s Responsibility for Will Design
A core element of the decision is the explicit assignment of the responsibility for determining heirs clearly and directly in form to the testator himself. A subsequent, informally inserted concretization cannot replace this obligation. Consequently, it is essential to make all significant individualizations already in the will or at least to define the groups of persons so precisely that no doubts in interpretation remain.
Conclusion and Outlook
The BGH decision makes it clear that inheritance law imposes strict standards on the form and clarity of testamentary dispositions. Testators—especially with entrepreneurial or international backgrounds—face an increased risk of creating significant uncertainties in succession through inadequately individualized or formally invalid amendments. Given the multitude of possible constellations, it is advisable to carefully examine all issues surrounding the design and effectiveness of testamentary dispositions.
