Lotus is behind in 27 bills adding up to almost $1 million, the Sunday Express reports.
Earlier, it emerged that the Enstone team, now linked with a buyout by the French carmaker Renault, is facing a winding-up petition brought by a disgruntled transmission supplier called Xtrac.
But F1 business journalist Christian Sylt said the unpaid bill to Xtrac is just one of 27 "unsatisfied judgements", according to court documents.
Elsewhere in the pitlane, it is reported that the backmarker Manor could be set for an investment injection.
Roger Benoit, the highly experienced correspondent for the Swiss newspaper Blick, said the interested parties are Americans James Carney and the well-known Tavo Hellmund.
