ORLANDO, Fla. -

The woman who is suing Casey Anthony for defamation has filed a motion to block her own deposition until Anthony completes hers.

Zenaida Gonzalez's attorneys say Anthony is stonewalling attorneys by pleading the Fifth Amendment during her recent deposition in the civil suit.

Gonzalez is scheduled to be deposed by Anthony's attorneys later this month, but she does not want to have to answer questions until Anthony does.

A hearing on the motion was held Wednesday morning. The judge must decide who gets to question who first in the civil case.

If the lawsuit goes to trial in April as scheduled, the burden is on Gonzalez and her attorneys to prove that she was defamed by Anthony and that she suffered damages as a result of Anthony's actions.

Anthony's attorneys argued their client could refuse to answer questions on the grounds her own words could incriminate her because she is appealing four misdemeanor convictions of lying to law enforcement. They also said questioning Gonzalez will reveal that the lawsuit is frivolous and based on lies.

Those charges were the only ones she was convicted of when she was tried this summer on charges of first-degree murder and child abuse in the death of her daughter, Caylee Anthony.

Caylee disappeared in July 2008 and her remains were found in Dec. 2008 in a wooded area near the Anthony family home.

While the toddler was missing, Anthony, 25, alleged that her daughter was kidnapped by a nanny named Zenaida Gonzalez.

Although the woman who filed the suit was never specifically identified as Caylee's kidnapper, Gonzalez says Anthony defamed her.

During the murder trial, Anthony's defense said Caylee was never kidnapped, but had instead drowned in the family pool in June 2008.

The judge is expected to rule on the matter by Thursday.
