A criminal attorney for Casey Anthony has accepted a subpoena requiring her to appear at her defamation trial.
Cheney Mason, who represented Anthony when she was on trial for the death of her daughter, Caylee, accepted a subpoena, requiring her to appear at the civil trial against Zenaida Gonzalez.
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.
