Comedian and former Tonight Show host Jay Leno is famous worldwide for his late-night show and extensive car collection. What many people may not know is the story of his wife, Mavis Leno, who has been by his side for over 40 years. At the age of 72, she is confronting a significant challenge – a diagnosis of Alzheimer’s disease.
Jay has recently taken the tough step of filing for conservatorship over her estate, allowing him to make legal and financial decisions on her behalf. As Mavis battles this progressive illness, let’s take a closer look at her life and marriage with Jay.
Jay Leno’s wife, Mavis P. Nicholson’s early life began on March 1, 1950, in New York City
Growing up in Queens, she later attended Catholic University in Washington D.C. After earning a degree in education in 1972, Mavis found herself teaching elementary school in Los Angeles. There, she crossed paths with Jay Leno, who was just starting his stand-up career. They connected and started dating in 1977, bonding over their shared sense of humor and love for cars.

Choosing not to have children due to the unpredictable nature of their careers, they devoted their time and energy to supporting each other. While Jay’s star rose with The Tonight Show, Jay Leno’s wife stayed mostly out of the limelight, managing their home and assisting Jay with various business ventures, including the short-lived cable TV channel Jay Leno’s Garage, focused on cars. Despite a cheating scandal in the early 1990s, their marriage remained strong.
In late 2023, friends and associates began noticing changes in Mavis’ behavior and memory. After months of tests, she received a diagnosis of Alzheimer’s disease in early 2024. As her condition worsened, Jay made the difficult decision to file for conservatorship in January 2024, allowing him to make essential decisions on her behalf.

He has canceled appearances to focus on her and is increasing his philanthropic efforts to support Alzheimer’s research. Despite the diagnosis, Mavis still enjoys time with Jay and their friends in the automotive community, sharing their passion for cars.
Jay uses his downtime to film segments for his car show, Jay Leno’s Garage, raising Alzheimer’s awareness and funding. In a touching segment from late 2023, Jay fought back tears, stating, “She’s my partner and has been with me this whole time, so it’s hard. But we’re taking it one day at a time and trying to make the most of whatever time we have.”

As committed as day one
As Jay Leno’s wife’s condition declines, Jay remains committed to caring for her at home and advocating for Alzheimer’s research through the Jay Leno Foundation. Despite the challenges, their love and decades-long partnership are helping them navigate this difficult period. Jay ensures that Mavis faces Alzheimer’s surrounded by the comfort and care of the family they built together.
Jay Leno recently took legal steps by filing court documents on a Friday, seeking a conservatorship from a family court judge
His aim is to establish a living trust and implement other estate plans to ensure that his 77-year-old wife, Mavis, possesses “managed assets sufficient to provide for her care” in the event of his passing before hers. The petition was filed in Los Angeles Superior Court, outlining Leno’s proactive approach to secure his wife’s well-being and financial stability in the face of her Alzheimer’s diagnosis.
“Unfortunately, Mavis has been progressively losing capacity and orientation to space and time for several years,” the petition said. “Jay is fully capable of continuing support for Mavis’s physical and financial needs, as he has throughout their marriage.”
The filing explicitly stated that Mavis Leno’s “current condition renders her incapable of executing the estate plan.” According to the court documents, she is currently undergoing treatment for both “dementia and mood disorder.” This information underscores the severity of Mavis’s health condition and the urgency felt by Jay Leno in taking legal measures to address her incapacitation and secure her financial future through the conservatorship.
According to the filed documents, the conservatorship is deemed necessary to empower Jay Leno to carry out estate plans designed to provide for Mavis and her brother, who happens to be her sole living heir apart from Jay himself. Given that the couple doesn’t have children, Jay is taking steps to ensure the financial well-being of Mavis and her brother through the planned estate arrangements.
Currently residing in Beverly Hills, Jay Leno, aged 73, is proactively addressing the specific needs arising from Mavis’s health condition and securing their family’s future. “Jay Leno has always handled the couple’s finances through the term of their 43-year marriage, and will continue to do so until his passing,” the petition said.
A scheduled hearing for the proposed conservatorship is slated for April 9
As indicated in the court documents, Mavis Leno is described as “able but unwilling” to attend the hearing. However, it’s noteworthy that she “does not wish to contest the establishment of a conservatorship.” Furthermore, Mavis does not raise objections to her husband serving as conservator and expresses no preference for another person to assume that role. This information suggests a level of agreement and understanding between Jay Leno and Mavis regarding the conservatorship arrangement, despite her inability or reluctance to attend the hearing in person.
