Diane Keaton, the award-winning actor, director, and real estate entrepreneur, reportedly left $5 million of her $100 million estate to her beloved dog, Reggie, after her death in 2025. While many Americans consider their pets to be family and want to provide for them, experts caution that overly lavish pet trusts can be challenged in court as unreasonable.

Why it matters

This case highlights the growing trend of pet owners making provisions for their animal companions in their estate planning, but also the need to strike a balance between ensuring a pet's care and avoiding excessive spending that could be contested. It also raises awareness about the many shelter animals in need of basic necessities like food and shelter, who often don't have the luxury of a trust fund.

The details

Keaton frequently posted about her dog Reggie on social media, and her reported $5 million bequest to him would make it one of the most extravagant pet trusts on record. However, overly generous pet trusts can be challenged in court, as happened with hotel magnate Leona Helmsley's $12 million trust for her dog Trouble, which was reduced to $2 million by a probate judge. Experts recommend pet owners provide for their animals through wills or pet trusts, but caution against going overboard, as the courts will determine what is a reasonable amount for the pet's needs.

  • Diane Keaton died on October 11, 2025.
  • Leona Helmsley's dog Trouble died in December 2010.

“An estimated 66% of all U.S. households include at least one pet. Many Americans consider their cats, dogs, tortoises or other animals to be part of their family, and their spending on those nonhuman relatives is immense.”

“One of the most over-the-top pet trusts came from Leona Helmsley, the New York hotel and real estate mogul known widely as the 'Queen of Mean.' She was famous for her pettiness and tough management style and for landing in prison for tax evasion.”
