Williams has not been notified officially about the legal action filed by NASCAR team Michael Waltrip Racing.
It was reported at the weekend that MWR is suing Grove-based Williams because it negotiated and hired new chief engineer Mike Coughlan while the Briton was already under contract.
"We are aware that a complaint was filed by Michael Waltrip Racing against the team and Mike Coughlan," the team is quoted as saying by France’s autohebdo.fr.
"We were not notified of any pending court process," added Williams.
