Lotus expect to complete a deal with Renault in the coming days that will see the French manufacturer return to Formula One as a works team in 2016.
Renault signed a letter of intent to buy back a controlling stake in Lotus in September and discussions have been ongoing without any announcement from either party.
But Lotus team principal Gerard Lopez believes the deal should be finalised soon.
"I think we are pretty much there with Renault," he told Sky Sports.
"I understand that Renault still have some things they need to clear with Formula One and FOM [Formula One Management], but as far as we are concerned we are pretty much at a deal now."
Lotus have been beset with financial problems in recent times, with the team having faced the threat of administration over unpaid tax.
