The girl alleges that two boys, who also had been drinking at the party, then sexually assaulted her on the grass next to the pool.
The lawsuit, which was filed in March, alleges that Norman and Kutner failed to ensure the girl’s safety, well-being and sobriety at their home by illegally providing alcohol to her and the other teens.
The lawsuit is seeking unspecified damages for pain, suffering, mental anguish and loss of enjoyment.
Norman leads the controversial, Saudi-backed LIV Golf tour, which announced last week that it would merge with the PGA and European tours.
Attorneys for the girl did not immediately respond to a phone call seeking comment. The names of the girl, her parents and the alleged assailants are not given in the lawsuit.
A Norman spokesperson had no immediate comment Friday. Norman and Kutner have been married since 2010. The daughter named in the lawsuit is Kutner’s from a previous relationship. The couple purchased the 1,100-sq metre mansion five months before the alleged attack for US$12 million (NZD$19.2 million), tax records show.
Norman, a native Australian, won 20 PGA tournaments and another 71 internationally, including two wins at the British Open. He was inducted into the World Golf Hall of Fame in 2001.
Norman has also had a successful business career, including golf course design, clothing, wine and real estate. Forbes Magazine estimates his net worth at US$400 million.
A spokesperson for the Palm Beach Gardens police department did not immediately return a phone call asking whether a criminal complaint was ever filed by the girl or her parents.
The lawsuit was first reported Friday by The Daily Mail.
