Judge Patricia Chew on Monday delayed the El Paso trial on the estate of the star of "The Jeffersons" television show. Hemsley died July 24 of lung cancer. His body remains at an El Paso funeral home amid the dispute.
Hemsley's will names his longtime manager Flora Enchinton of El Paso as sole beneficiary.
Richard Thornton of Philadelphia sought the DNA testing and must provide results by Oct. 15. The estate trial has been rescheduled for Oct. 31.
Hemsley was born in Philadelphia but lived in El Paso for the past 20 years.
Court documents indicate Hemsley's estate is worth more than $50,000.
