The ex-wife of late NASCAR icon Greg Biffle is suing his estate for $10million following the plane crash that claimed seven lives, including their 14-year-old daughter Emma.Nicole Biffle, 50, filed court documents demanding eight figures from the racing icon’s estate alongside an emergency order to freeze all further distributions to ensure sufficient funds remain for surviving creditors and victims’ families.Greg, 55, his wife Cristina, and their young son Ryder were tragically killed alongside Emma and three family friends on December 18, 2025, when his private Cessna 550 jet went down near Charlotte after suffering mechanical issues shortly after takeoff.In the wrongful death filing, according to US Weekly, Nicole made the claim that Emma was feeling ill on the morning of the flight and begged not to travel, but alleged that Greg insisted she board the aircraft anyway.The lawsuit alleges gross negligence against Greg and others involved in operating the twin-engine jet.An additional lawsuit has also been brought against Biffle’s estate on behalf of fellow crash victims Dennis and Jack Dutton, seeking $30 million in damages. Late NASCAR icon Greg Biffle’s ex-wife Nicole is suing his estate for $10million after his death The late NASCAR icon is seen with his wife, Christina, their son Ryder, and his daughter, EmmaA preliminary report released by the National Transportation Safety Board (NTSB) in January revealed that Dennis Dutton, a retired pilot, was at the controls alongside his son Jack, who was acting as copilot despite not being qualified for the role.While Dennis was certified to fly the aircraft, federal regulations required a fully qualified copilot, a standard neither Jack nor Biffle – who held a pilot’s license – met for that specific aircraft.Investigators found that Dennis had initially flown the plane before briefly handing over controls to his son, only to retake them moments before impact after discovering the altimeter had failed and the left-side flight instruments were malfunctioning.During an emergency attempt to return to the runway, the aircraft struck tree branches and light stanchions before plowing through an airport perimeter fence.Greg and Nicole tied the knot in 2007 and welcomed Emma four years later before separating in 2015. Federal aviation officials have warned that a comprehensive, final NTSB investigation report into the disaster could take up to two years to complete.Recently, a Georgia man was arrested for burglarizing Biffle’s home after learning that he and his family had died in the plane crash.Terrell Williams, 44, was charged with second-degree burglary, safe cracking, money laundering and other felonies, Iredell County Sheriff Darren Campbell announced at a news conference.

Jail records did not list an attorney.Campbell said investigators were led to Williams in July, when Cobb County police arrested him and found items taken from Biffle’s home.Authorities reported a break-in at the home on Jan. 8 and have said $30,000 in cash, two Glock handguns, NASCAR memorabilia and gold and silver coins were stolen.Investigators have recovered some of the stolen items, including NASCAR memorabilia, Campbell said. They also found a radio-frequency detector they believe Williams used during the burglary to locate security cameras.He said Williams is also suspected in another North Carolina burglary that occurred when a law enforcement officer was in the hospital.
