Casey Anthony exits the Orange County Jail, early Sunday, July 17, 2011.
Orlando, Florida (WKMG) -- Casey Anthony has been served a subpoena requiring her to appear at the civil trial against Zenaida Gonzalez, according to attorney Matt Morgan.
Morgan, Gonazalez's attorney, announced via Twitter on Thursday morning that the subpoena had been served.
Anthony's attorney, Cheney Mason, who represented Anthony when she was on trial for the death of her daughter, Caylee, accepted the subpoena on Monday.

Gonzalez shares a similar name as a fictitious baby sitter -- Zenaida Fernandez Gonzalez -- whom Anthony initially said kidnapped her 2-year-old daughter in 2008.
At Anthony's murder trial last summer, Anthony's defense claimed Caylee drowned in the family's swimming pool and, therefore, had not been abducted. Caylee's remains were found in December 2008. Anthony was acquitted of murder charges in July 2011 but was found guilty of lying to authorities.
The civil trial is slated to start in January 2013.
