David K. Davoudlarian, the Annandale gynecologist accused in a pair of civil lawsuits of strangling his wife, is being sued for $4,140.40 in legal fees by a law firm that represented him for 13 months.

The Northern Virginia firm of Odin, Feldman & Pittleman, which represented Davoudlarian from the day after his wife's body was found until last July, has filed papers in Fairfax County Circuit Court asserting that he owes the firm that amount in unpaid fees.

Davoudlarian has responded in court papers: "The amount owed has been paid in full," adding that he "may have a counterclaim" against the law firm.

No countersuit has been filed, and neither Davoudlarian nor the lawyer he has retained to represent him in the law firm's suit could be reached yesterday. No date has been set for trial of the suit.

Davoudlarian's 40-year-old wife, Susan, disappeared without explanation from the couple's home on June 4, 1983. Eight days later she was found strangled, her nude body wedged beneath the back seat of her station wagon, which was parked at Dulles International Airport.

No criminal charges have been filed in her death, but the woman's daughters and her estate have filed separate civil suits alleging that the doctor killed his wife.

The month-long trial of the first of those suits, which sought $10 million in damages from Davoudlarian, ended in a mistrial last month when a seven-member jury was unable to agree on a verdict, splitting 5 to 2 against the doctor.

That suit is expected to be retried later this year.

Rodney Leffler of Odin, Feldman & Pittleman represented Davoudlarian through the filing of those suits until last July, when he withdrew. Neither Leffler nor Davoudlarian have said why Leffler stopped representing the doctor.

Leffler said yesterday the $4,140.14 represents the last part of his firm's bill for 13 months of services to Davoudlarian. He declined to say what the total bill had been.

Davoudlarian testified at the trial of the first civil suit that his income from a flourishing gynecological practice was $200,000 a year, but had been reduced by 70 percent because of adverse publicity resulting from the lawsuits against him.

After Leffler withdrew as his attorney, Davoudlarian retained Jack Rhoades and Plato Cacheris, who represented him in pretrial proceedings and defended him at last month's trial, and who are expected to defend him at the retrial. Rhoades and Cacheris are not defending him in the suit over the legal fees.

Cacheris said the bill for his services alone was $70,000, but yesterday he declined to say whether or not he had been paid. He said he knew of the bill dispute over the prior legal fee, and it "does not worry me at all."
