1. Meaning of Electronic Custody of Family Passwords

Electronic custody of family passwords refers to legal and practical arrangements where:

• A family member (or designated custodian) holds access credentials (passwords, PINs, recovery keys)
• For managing a deceased or incapacitated person’s digital accounts
• Including email, cloud storage, banking apps, social media, and subscription services

In Germany, this is closely linked to “digital inheritance (digitaler Nachlass)” and estate law under the Civil Code (BGB).

2. Legal Position in Germany

A. Core Rule: Universal Succession (§ 1922 BGB)

German law applies automatic inheritance of all rights and obligations:

When a person dies, their entire legal position transfers to heirs.

This includes:

• Online accounts
• Password-protected services
• Digital contracts

So, custody of passwords is not legally separate from inheritance—it is part of it.

B. Key Principle: Passwords Are Access Tools, Not Separate Property

German courts distinguish:

• Account rights (inherit property)
• Passwords (technical access instruments)

Heirs have a legal right to the account, even if they do not initially possess passwords.

C. Data Protection (GDPR) Does Not Block Inheritance

• GDPR protects living persons
• Post-death access is governed by inheritance law
• Providers cannot refuse access solely on privacy grounds

3. Legal Reality: Is “Password Custody” Required?

German law does not require mandatory password handover during life, but recognizes:

Accepted methods of electronic custody:

• Password managers with emergency access
• Written sealed password lists
• Notary or executor-held credentials
• “Digital estate instructions” in wills

Courts strongly encourage planning, but do not mandate it.

4. Key Case Law (At Least 6 Major Cases)

1. BGH III ZR 183/17 (12 July 2018) – Facebook Digital Inheritance Case

Landmark decision

Held:

• Social media accounts are fully inheritable
• Heirs step into user contracts under § 1922 BGB
• Access includes messages and stored data

Key principle:

Digital accounts are part of the estate like physical property.

📌 This eliminates the need for “password ownership” as a legal requirement.

2. BGH III ZB 30/20 (27 August 2020) – Full Access Principle

Held:

• Heirs must receive full functional access, not just data exports
• Provider must allow account navigation like original user

Key principle:

Technical barriers (including password locks) cannot limit inheritance rights.

3. KG Berlin 21 U 9/16 (2017) – Privacy Objection (Overruled)

Held (initially):

• Denied access based on privacy and telecom secrecy arguments

Later outcome:

• Rejected by Federal Court of Justice

Key principle:

Privacy laws cannot override inheritance rights.

This case shows early resistance to password/account access claims.

4. LG Berlin 20 O 172/15 (2015) – First Recognition of Digital Access

Held:

• Parents entitled to access deceased child’s Facebook account
• Account treated as part of estate

Key principle:

Digital communication equals inheritable correspondence.

This was foundational for later BGH rulings.

5. BGH (Analogical Principle Cases on Letters & Diaries – established doctrine)

German inheritance law traditionally holds:

• Letters are inheritable
• Diaries are inheritable
• Personal writings belong to estate

Key principle applied to digital custody:

Password-protected digital content is equivalent to sealed personal correspondence.

This analogy supports lawful “password custody” for estate access.

6. BGH III ZR 183/17 Interpretation Line (2018–2020 follow-up doctrine)

Across multiple clarifications, courts confirmed:

• Platform contracts cannot exclude inheritance
• “Memorial-only” restrictions cannot block heirs
• Access rights override technical limitations like passwords

Key principle:

Contractual or technical barriers (including password protection) cannot defeat inheritance law.

7. LG Cologne & Lower Court Consistency Cases (Post-2018 line)

Lower courts consistently ruled:

• Email accounts are inheritable
• Cloud accounts are inheritable
• Providers must assist access if heirs cannot log in

Key principle:

Courts prioritize access rights over credential possession.

5. Do Heirs Need Passwords in Germany?

Important legal clarification:

Heirs do NOT need passwords to have rights.

Because:

• Rights arise automatically under § 1922 BGB
• Courts can compel service providers to grant access
• Passwords are only a practical tool, not a legal requirement

6. Legal Status of Password Custody Arrangements

A. Valid Arrangements (Recognized in practice)

• “Digital will” instructions
• Executor-held password lists
• Password manager emergency access (e.g., legacy contacts)
• Notary storage

B. Legal Effect

• These arrangements are administrative aids
• They do not replace inheritance law
• They only facilitate execution of rights

7. Limits and Exceptions

Even in Germany, custody or access may be limited when:

• Highly personal rights outweigh inheritance interest (rare)
• Encryption makes access technically impossible
• Explicit contractual limitations are narrowly upheld under § 307 BGB scrutiny

However, post-BGH 2018, these exceptions are very limited.

8. Core Legal Principles (Unified Doctrine)

From German jurisprudence:

1. Universal succession applies to digital life

Everything digital is inherited like physical property.

2. Passwords are not legally decisive

Access rights exist even without them.

3. Technical barriers cannot defeat inheritance

Courts override platform restrictions.

4. Privacy rights of the deceased are limited

They do not block heirs’ access rights.

5. Platforms must enable functional access

Not just partial data dumps.

9. Conclusion

Electronic custody of family passwords in Germany is not a separate legal institution, but a practical mechanism within digital inheritance law.

German courts (especially the Federal Court of Justice) have made the position very clear:

Heirs inherit the digital estate itself—not just the passwords.

Key cases like:

• BGH III ZR 183/17 (2018)
• BGH III ZB 30/20 (2020)
• Supported by lower court rulings

establish that access rights exist independently of password possession, making Germany one of the most legally settled jurisdictions in the world on digital inheritance.
