Lindsay's Santa Monica-based attorney, Shawn Chapman Holley, tells E! News the starlet wants to "explore all legal options," including the possiblity of filing a criminal complaint against her father.
"Lindsay's concerned about recent actions of his," says Chapman. "She is concerned about defamatory statements about her own personal safety and has instructed me to explore all legal options available to her to get him to stop and to leave her alone."
At issue for Holley is when and where the elder Lohan may have taped the phone call, because that could determine whether she would be able to file a criminal report or merely a defamation or invasion of privacy suit.
"She just wants me to take a look at what appears to be escalating destructive behavior," the lawyer says "We're trying to figure out [where the tape was recorded] right now. If it was in California, the law is very clear. You can't do that.
"Both parties have to authorize it being recorded," says Chapman,"and there's no question Lindsay did not authorize it. If it happened here, he's in violation of the criminal law."
In any case, a petition for a restraining order is the most likely scenario at the moment and Holley says one could be filed by the end of the week.
