In the latest chapter of Australian golf legend Greg Norman's divorce, his ex-wife is now alleging that he cut off her credit cards and changed the locks on their Florida mansion.

Lawyers for 57-year-old Laura Norman, who was married to the multiple-PGA-winner for twenty-five years, wrote in court papers this week that Greg Norman was holding money and property "hostage" in order to force her to accept a new settlement. According to the AAP, attorneys Jack Scarola and Russell J. Ferraro said in the filing that the golfer intended to "starve [her] out so she has no choice but to surrender to his positions."

Scarola and Ferraro explained that Greg Norman, 52, had changed the locks and fired the housekeeper of the couple's mansion, which is valued at $21 million. He also allegedly cut off the credit cards she was holding through one of his companies, Great White Shark Enterprises. Her lawyers added that she had been using the cards to pay her legal bills and for general living expenses. "She now has no means of support," they wrote to Florida Judge Lawrence Mirman.

In response, Greg Norman's divorce attorneys told the Associated Press that he had already paid Laura Norman $725,000 to go toward the legal expenses. "Let's just say that during the course of this case, Mrs. Norman has been exceedingly well funded and that her lifestyle has not been compromised one iota," said one of the golfer’s lawyers, Martin L. Haines III. "And in no way would Mr. Norman cut off his wife’s credit cards."

Greg and Laura Norman had supposedly agreed in June upon a divorce settlement, in which she would receive $100 million. But these new allegations reveal that their divorce has remained bitter and vindictive.

Norman, a two-time winner of the British Open, is now said to be romantically involved with former U.S. tennis star Chris Evert.

The bitter, antagonistic style of the Normans' divorce is far from ideal, especially when the couple is in the public eye. And it's especially damaging when children are involved. Click here for some advice on how you can deal with divorce-related anger.
