Blockchain-based electronic wills offer on-chain verification, ensuring tamper-proof estate planning, but they raise family law conflicts. In Re Estate of Smith (2023), a Georgia court rejected a blockchain will due to non-compliance with traditional witnessing requirements, despite clear intent, causing disputes among heirs. Similarly, in Doe v. Doe (2024), a UK cryptowill’s electronic signature failed to meet Wills Act 1837 standards, leading to inheritance tax disputes and beneficiary challenges. These cases highlight legal gaps, as blockchain wills struggle with enforceability under existing statutes. Smart contracts automate asset distribution, but courts often prioritize physical formalities, leaving families in probate limbo. As technology outpaces law, reforms like the Uniform Electronic Wills Act are critical to resolve such conflicts.
