Greg Biffle's ex-wife, Nicole Biffle, has filed a $10 million lawsuit against the estate of the late NASCAR driver following a fatal plane crash that killed their 14-year-old daughter, Emma. The lawsuit, filed in court documents, also requests an emergency order to freeze all further estate distributions to ensure sufficient funds are available for surviving creditors and victims' families.
Greg Biffle, 55, his wife Cristina, their son Ryder, and Emma were among seven people killed on December 18, 2025, when Biffle's private Cessna 550 jet crashed near Charlotte after experiencing mechanical issues shortly after takeoff. Three family friends also died in the incident.
In the wrongful death filing, Nicole Biffle claims that Emma was not feeling well on the morning of the flight and expressed a desire not to travel, but that Greg insisted she board the aircraft. The lawsuit alleges gross negligence against Greg and others involved in the operation of the jet.
An additional lawsuit has been filed against Biffle's estate on behalf of fellow crash victims Dennis and Jack Dutton, seeking $30 million in damages.
A preliminary report from the National Transportation Safety Board (NTSB) released in January indicated that Dennis Dutton, a retired pilot, was at the controls, with his son Jack serving as copilot. However, federal regulations required a fully qualified copilot for the aircraft, a standard that neither Jack nor Greg Biffle, despite holding a pilot's license, met for that specific jet.
The NTSB investigators found that Dennis Dutton initially flew the plane before briefly handing the controls to his son. He retook control shortly before the crash after discovering the altimeter had failed and the left-side flight instruments were malfunctioning. During an attempted emergency return to the runway, the aircraft struck tree branches and light stanchions before crashing through an airport perimeter fence.
Greg and Nicole Biffle were married in 2007 and had Emma four years later before separating in 2015. The NTSB's final investigation report into the disaster is expected to take up to two years to complete.
Separately, a Georgia man was arrested in July and charged with multiple felonies, including second-degree burglary and safe cracking, for allegedly burglarizing Biffle's home after learning of the family's deaths. The suspect, Terrell Williams, 44, is accused of stealing $30,000 in cash, two handguns, NASCAR memorabilia, and gold and silver coins. Investigators have recovered some of the stolen items.
