Legal news and notes from Aphiwat Law

The 1,000 Wills Project
Research Chiang Mai, 1 June 2026

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.

Case examples

Will Writing and Probate

Real stories from our practice, shared to show how careful, honest work protects each client’s final wishes.

01
Cross-border probate · 2020

A Father’s Final Gift: A Will That Crossed Borders and Barriers

In 2020, I met an American man who was living in a care home in Chiang Mai. He wanted to make a will to leave his condo in Thailand to his son. I helped him draft the will properly under Thai law. Just four months later, he passed away. It was during the Covid situation, so it was very hard to complete the probate, but in the end we managed to finish everything. This was one of my first probate cases, and it made me feel that estate planning is really meaningful, especially for families who live far apart.

02
Contested will · 2021

A Will, a Camera, and a Brother’s Last Wish

In 2021, I helped a bedridden Australian man in Chiang Mai who wanted to change his will and give everything to his long-lost brother instead of the previous beneficiary. I happened to bring my camera and recorded a video during the will signing. Six months later, he passed away. After that, the previous beneficiary tried to challenge the will in court, but we won. The judge said it was clear from the video that he truly wanted to give everything to his brother. This case taught me that doing a will properly and keeping good evidence can protect the client’s real wish, even when others disagree.

03
Honesty & trust

A Familiar Face, a Fair Fee, and a Final Wish Fulfilled

An Italian man came to me for will advice about two years before his passing. He already had a public will, so I gave him guidance and did not expect to hear from him again. Then one day, his wife walked into my office and said her husband had just died. I recognized her instantly. I helped her through the probate process with my standard fee. Later, she told me her colleague paid over 200,000 baht to another firm but got no results for months.

Charitable legacy

When a Legacy Becomes a Gift to the World

A Thai-French couple with no children came to me to prepare their wills. They owned many pieces of land and several houses across Thailand. Instead of passing it all to relatives, they decided to give more than half of their estate to charity. I helped them organize their assets clearly and made sure the legal structure would protect their wishes.
