Jay, 73, and Mavis, 77, who have been married for 43 years, have never spoken publicly about her health battle. The comedian had often affectionately mentioned his wife on The Tonight Show, which he hosted between 1992 and 2009 and then again between 2010 and 2014. She has also occasionally accompanied him to red carpet events, most recently last November, when they attended the Improv comedy club’s 60th anniversary show in Hollywood.

According to NBC News, Jay stated in the petition that he believes Mavis consents to him being appointed conservatorship of her estate. Records show a follow-up court hearing has been set for April 9.

Jay himself has also battled health issues in recent years. In late 2022, he suffered serious burns to his face, arms and hands in a gasoline fire that erupted in his garage while he was working to repair a clogged fuel line in his 1907 White Steam Car, one of his collectible vintage vehicles. Two months later, in January 2023, Jay got into a motorcycle accident, breaking his collarbone, two ribs and his kneecaps.

Following his injuries, The comedian underwent reconstructive surgeries and in March 2023, he said on Dana Carvey and David Spade‘s podcast Fly on the Wall that he received “an all-new face” and “brand-new ear.”
