Legal news and notes from Aphiwat Law
I Published the First Universal Will Template Derived from 700 Historical Wills Across Six Countries
After years of collecting and months of intensive reading, I am pleased to announce the publication of findings from the 1,000 Wills Project. The research analysed approximately 700 historical wills from archival collections in the United States, Canada, Australia, and New Zealand, covering the period from 1873 to 1967.
The project produced a universal will template identifying nine structural elements that appear in a fixed sequence across all six jurisdictions and nearly two centuries of practice. The research was enabled by multimodal artificial intelligence, which read 1,313 scanned archival images while all analysis and interpretation were my own.
Three deliverables are now available: an academic article titled “Structural Patterns in Common Law Testamentary Instruments,” the Universal Will Template with empirical frequency data, and a seven point Will Analysis Framework for evaluating testamentary instruments. Approximately 300 wills in the corpus remain under analysis.
Knowledge Exchange: AEPA (Asia Estate Planning Association), Singapore
As a member of the Asia Estate Planning Association (AEPA), Mr. Aphiwat was invited to meet and exchange knowledge with the AEPA Board of Directors in Singapore. This engagement with leading estate planning professionals across Asia including AEPA President Mr. Allen Lim deepened our expertise in cross-border estate planning and reinforced our focus in Thai wills and estate administration.
Guest Speaker at AIA Wealth Center, Singapore
Mr. Aphiwat was invited by SmartWills Singapore to deliver a lecture on Thai inheritance and will law to financial advisors at AIA Wealth Center, Singapore. The session was a rich exchange of knowledge between Thai and Singaporean legal and financial professionals, highlighting the differences between Thailand’s civil law system and Singapore’s common law heritage and the unique estate planning tools each system offers.
