ORLANDO, Fla. -

The night Casey Anthony was found not guilty of murdering her daughter, she was served with a subpoena to give a deposition in the civil case against her.

A process server arrived at the Orange County Jail at 7:30 p.m. Tuesday, just five hours after a jury of 12 found her not guilty of all felony charges against her in Caylee's death.

Anthony is being sued by a woman named Zenaida Gonzalez, the same name Anthony gave investigators as the nanny she said had kidnapped Caylee. During her murder trial, Anthony's defense team admitted that she had invented the nanny, and said Caylee had actually drowned in the family pool.

Gonzalez, who is represented by attorney John Morgan, is suing Anthony for defamation.

Her attorneys filed a notice for deposition for 10 a.m. on July 19 at Morgan's office. The notice indicated the deposition could take several days.

When Morgan took depositions from Anthony's parents, he posted the complete videos online.

After Anthony was served with the subpoena, she was visited by three members of her defense team, as well as her attorney for the civil case.

Anthony will face sentencing at 9 a.m. Thursday. She was found guilty of four misdemeanor charges of providing false information to a law enforcement officer.

The maximum sentence for each count is one year in prison. Legal experts expect that she will be sentenced to serve them concurrently, which would be a 365 day sentence, but because she has already served 1,042 days in jail, she could be released Thursday.

If she is ordered to serve the terms consecutively, she could remain in the Orange County Jail until next February.

If Anthony is released on Thursday, it is expected that special precautions will be made to ensure she safely leaves the courthouse. When she was released from jail on bond in 2008 several times, crowds awaited her.

Anthony has already served the probation she was sentenced to on check fraud charges last year by Judge Stan Strickland, who later removed himself from the case. Nothing would stop her from leaving the state, if she chooses to, once she is released.

Publicist Frank Torres said Anthony could get a huge payday from her first interview. He said numbers are already being tossed around, starting at $750,000.

"This story has demonstrated its ability to capture an international attention and she has a very real chance to bank roll herself for the rest of her life," Torres said.

Torres said, depending on how revealing Anthony is in the interview, she could then potentially boost the asking price for a book deal.

He said book advances and movie rights could set new standards in the industry and potentially earn Anthony millions.

Publishing industry experts said they would not be surprised to see a book from Anthony on shelves within six months.
