Romain Grosjean has confirmed that he has “commenced an arbitration proceeding” against Andretti Autosport following his exit from the team.
Grosjean will not return to Andretti next year in the NTT IndyCar Series, having linked up with the team in 2022.
The Frenchman scored three podiums with the team during his term.
Andretti has not formally announced that it will not continue with Grosjean next year, however its split has been expected as it has made several driver announcements while not mentioning Grosjean.
These included ex-F1 driver Marcus Ericsson, and a multi-year extension of Kyle Kirkwood.
Grosjean released a statement on social media, suggesting that the split between the two parties was not a civil break.
“I enjoyed working with the IndyCar team at Andretti Autosport, and am proud of the successes we shared through two seasons,” he wrote.
“I am thankful for the many friendships developed at the highest level of American open-wheel racing.
“I had expected to continue racing with the fine people of Andretti Autosport in the coming year.
“I am disappointed that is not being fulfilled, and wish Andretti team members well. I am pursuing other options to continue my IndyCar career in pursuit of excellence.
“I have commenced an arbitration proceeding against Andretti Autosport, seeking to protect by rights. I am represented by John Maley and Mark Owens of Barnes & Thornburg, LLP.”
