The attorney for a woman convicted of running over her cheating husband is accused of overcharging her during her murder trial.

Lawyer George Parnham never provided former Friendswood dentist Clara Harris detailed invoices for how he was using extra funds she paid, according to papers filed in the lawsuit Wednesday.

Parnham, according to the filings in Harris County civil court, initially required that Harris pay a $75,000 fee for representing her at the trial court level.

The attorney did not give his client a written agreement. He ended up receiving more than $235,000 over the course of representing Harris, 46.

Lawyer Jim Drexler, representing Parnham, did not return a telephone call from The Associated Press early Thursday.

Harris is serving a 20-year sentence for running over her orthodontist husband, David, with her Mercedes-Benz after finding him with his mistress at a Clear Lake-area hotel in 2002. She is appealing her conviction.

Bills from experts who aided in Harris' defense remain outstanding, Parnham said in the Houston Chronicle's Thursday editions.

"George Parnham, to this very day, has Clara Harris' best interest at heart," Parnham's attorney Jim Drexler told Local 2.

While Harris was under psychiatric care and under medication, the lawsuit also claims, Parnham urged her to sign paperwork that he maintained would help "preserve her estate."

While Harris was in the Harris County Jail's psychiatric unit, she signed a $300,000 promissory note on Feb. 18, 2003. Also, she signed a security agreement listing her Friendswood home, dental practices and a lake house as collateral.

"In reality, these documents were for the sole and exclusive benefit of defendants (Parnham) and to the detriment of Ms. Harris," stated the filings by attorney Dean M. Blumrosen.

In the lawsuits, he claims Parnham breached his fiduciary duty and violated the Texas Deceptive Trade Practices and Consumers Protection Act. A temporary restraining order and a temporary injunction is also sought to keep Parnham from seeking relief from the promissory note signed by Harris.
