Real Housewives of Beverly Hills star Erika Jayne's top Los Angeles lawyer husband may soon be defending...himself.

Thomas Girardi, 76, along with fellow lawyer Robert Finnerty and the law firm Girardi-Keese have been slapped with a federal lawsuit. Girardi is a founding partner of the firm.

In court documents obtained exclusively by Daily Mail Online Tom is accused of defrauding clients out of millions of dollars won in a class action lawsuit.

It claims Girardi used the $130 million he won for them on an escrow payment, his divorce attorney and his partners.

A man named Paul Kranich filed the lawsuit in California to get Girardi to pay up the money Kranich claims he illegally stole.

In the lawsuit, Kranich alleges it is a case of: 'conspiracy, criminal fraud, theft and breach of trust in which Thomas V. Girardi, Girardi-Keese, a well-known plaintiff's law firm ('Girardi'), and other attorneys and employees of Girardi-Keese participated in and aided and abetted a scheme to defraud their clients by charging excessive fees and costs and fraudulently converting settlement proceeds to which Plaintiff and other clients.'

The law firm represented employees of Lockheed Corporation in a legal battle with the company over chemical exposure.

The employees reached a settlement with Lockheed, after battling for nine years between 1992 and 2001, totaling $130 million for the plaintiffs.

Kranich explains the plaintiffs in that case have had several legal issues with Girardi and his firm since the settlements were reached.

He says during the litigation of those lawsuits it was discovered that Girardi spent the settlement funds from the Lockheed case for other improper purposes.

The alleged improper uses outlined in court papers include six figure payments to other clients they represented in completely separate cases as well as payment for Girardi's personal and unreleased business debts.

Specific numbers include: $250,000 to an aviation company owned by Girardi, $100,000 to a man believed to be Girardi's divorce attorney - he has two ex wives, $350,000 to Western Bank for 'fees', $50 to an associate at the firm who never worked on the Lockheed case, $1 million to 'Global Client Payments' and allegedly more than $827,000 to 'Lockheed Litigation' plaintiffs - and even a $500,000 payment on a real estate escrow in which Giradi was involved and was unrelated to the Lockheed litigation.

Girardi has fired back claiming the allegations are false and is demanding his former client’s $50 million dollar lawsuit be thrown out of court in legal papers filed Thursday.

Kranich also accuses the law firm of charging excessive fees for their work.

The documents state, 'Girardi is believed to have charged Plaintiff a total contingency fee of 40 percent of total gross proceeds, even though Girardi had agreed to accept only one-third in fees on many of the settlements.'

Kranich also accuses Girardi of lying about the payments and claiming they were related to the Lockheed case.

He adds that the law firm swindled the plaintiffs out of millions from the settlement and were not paid the full amount each plaintiff was owed.

The suit is demanding the cut of the Lockheed settlement that was paid to Girardi and his firm for representing them be disgorged, compensatory and general damages, restitution and punitive damages in the amount of $50 million.
