Bitcoin differs fundamentally from any other asset you own. There is no bank that grants your heirs access in the event of your death. There is no safe-deposit box a notary can open. If your heirs do not know where your private keys are and how to access them, your Bitcoin are irretrievably lost.
Every year, billions in Bitcoin holdings are lost because no estate planning exists. In this guide you will learn how a professional inheritance arrangement for Bitcoin works and what you need to pay attention to.
What happens to Bitcoin without estate planning?
Bitcoin is what is known as a bearer asset: whoever controls the private keys controls the wealth. Unlike a bank account, a securities portfolio or a property, there is no central institution that regulates access for heirs. Without estate planning, your heirs are faced with an unsolvable task.
The problem does not only affect technically inexperienced heirs. Even with technical understanding, access without documented steps is barely possible if a multisig setup, a passphrase or geographically distributed keys are involved.
The consequence: without an explicit inheritance arrangement, your Bitcoin will most likely be lost to your heirs in the event of your death.
Why a will alone is not enough
Many Bitcoin owners assume that it is sufficient to record the seed phrase in their will. This is problematic for several reasons.
A will is opened after death and is generally visible to all heirs and parties involved. Seed phrases or private keys have no place in a will, because any person with access to this information can immediately and irreversibly dispose of the entire wealth.
In addition, a will contains no technical instructions. Even if the keys were transmitted securely, most heirs would not know what to do with them.
The three pillars of professional Bitcoin estate planning
A well-considered inheritance arrangement for Bitcoin addresses three areas at the same time: technical access, documentation and the legal framework.
1. Technical access: redundancy instead of single point of failure
The security concept itself must be designed so that the inheritance case is represented technically. In a multisig setup (for example 2-of-3) this means: one of the three keys is deposited in such a way that the heirs can access it in the defined case, without anyone other than you having access during your lifetime.
The geographic distribution of the keys protects against physical risks such as burglary, fire or natural disasters. At the same time, the estate plan must ensure that the heirs can bring together all the necessary keys.
2. Documentation: understandable even without technical knowledge
A frequently underestimated aspect: your heirs must understand what to do. Professional estate documentation contains a step-by-step guide that can be followed even without deep technical understanding.
This documentation describes where each key is located, how the hardware wallets are operated, in what order the steps are to be carried out and whom the heirs can turn to with questions.
3. Legal framework: alignment with the existing will
The technical estate plan should be aligned with the existing will and the overall inheritance arrangement. We recommend carrying out the technical estate planning in parallel with the legal arrangement.
Common mistakes in Bitcoin estate planning
From our consulting practice we see recurring mistakes, which we summarise here.
Seed phrase in a safe-deposit box without context: the box is inherited, but without documentation the heirs do not know what the 24 words mean or what software they need to use.
Password manager as the only storage location: if the password manager itself is protected by a master password that nobody knows, the problem is only shifted.
Relying on a single person: if only one trusted person knows the full access, a new single point of failure arises.
No regular updates: security concepts and inheritance arrangements must keep pace with changes in life circumstances.
Inheritance tax on Bitcoin in Germany
Bitcoin holdings are subject to inheritance tax in Germany. The value is determined at the time of death and taxed according to the regular allowances and tax brackets. Spouses have an allowance of EUR 500,000, children of EUR 400,000 per parent.
The fiscal valuation of Bitcoin in the inheritance case is not trivial and should be coordinated with a specialised tax advisor. Schwarzberg does not provide tax advice on this, but recommends including this aspect in the overall planning at an early stage.
How Schwarzberg implements estate planning
As part of setting up your security concept, Schwarzberg creates a detailed estate plan. This ensures that during your lifetime nobody other than you has access to your wealth. In the event of your death, a multi-stage process is initiated that guarantees your heirs access to your Bitcoin.
Our approach is based on three principles. First, we never have access to your private keys. Second, the system works without our involvement — your heirs are not dependent on us. Third, on request we accompany your heirs in the inheritance case during the technical execution.
Conclusion
Bitcoin estate planning is not an optional add-on. For anyone holding significant Bitcoin in self custody, it is a necessity. The good news: with a professional security concept, estate planning can be integrated elegantly without compromising security during your lifetime.
