Using artificial intelligence to draft a will presents several critical risks, despite its potential for convenience and lower upfront costs. One primary concern is that AI cannot fully assess an individual's unique family circumstances, financial situation, or inheritance tax position. This can lead to wills that fail to accurately reflect the testator's true intentions, potentially resulting in assets being passed to unintended beneficiaries or increased inheritance tax liabilities.
Legal experts emphasize that a will is more than just a document; it requires precise legal wording, proper execution (signing and witnessing), and suitability for complex personal and financial situations. AI tools are prone to generating unclear wording, incorrect clauses, or even citing non-existent legal precedents, a phenomenon known as "hallucinations." For example, an experiment found that AI-drafted wills failed to use language precise enough to prevent ambiguities that led to a 12-year legal dispute in a real-world case. Such issues can lead to costly and emotionally draining rectification processes or challenges to the will's validity after death.
Furthermore, AI cannot assess crucial factors like testamentary capacity—whether someone understands the implications of their will—or identify undue influence. This lack of human judgment leaves vulnerable individuals unprotected. There are also significant privacy and data security risks, as AI tools may require detailed personal, financial, and medical information, which could be exposed or misused. Unlike legal professionals, AI platforms are unregulated and cannot be held accountable for errors, meaning there is no recourse if an AI-generated will proves invalid or ineffective.
