Michael Lohan, father of Lindsay Lohan, arrives at the Beverly Hills courthouse, Tuesday, July 20, 2010, where Lindsay was taken into custody to begin serving her jail sentence for a probation violation.
Michael Lohan is due in a Southampton courtroom on Aug. 18.
His fiancee, 27-year-old Kathryn Major, told police that she and the 50-year-old Lohan argued on Monday over a missed cell phone call at the home they shared in Water Mill on Long Island. Major says Lohan kicked and threatened her.
Lohan's attorney, Lisa Bloom, says her client denies all the charges. She confirmed in an e-mail that the couple, who were engaged in April, have split.
Lohan was in Los Angeles this week to watch his daughter surrender to begin a 90-day jail term for violating terms of her probation.
