A Los Angeles judge granted Leno conservatorship over her inheritance due to her “declining health and diminished mental capacity.”

Her neurologist notes she is gradually losing awareness, but Leno continues to care for her with “unwavering devotion.”

Leno is also preparing for his own passing, planning to leave his $52 million car collection to a museum through the JDM Foundation, his nonprofit. Additionally, $7 million will go to his nephew and Mavis’s brother.
