A former boyfriend of Anna Nicole Smith has obtained a court judgment ordering the reality TV star out of her oceanfront residence and he plans to seek her forcible eviction unless she leaves by Thursday, according to his lawyer.

Emerick Knowles, the attorney for South Carolina businessman G. Ben Thompson, said he entered the default judgment on Tuesday after Smith missed a deadline to respond to his suit declaring his client the rightful owner of the gated mansion known as "Horizons."

Howard K. Stern, an attorney who is Smith's companion, said that Knowles had "improperly obtained" the default judgment.

"I can assure you that we will continue to stay in Anna Nicole's house as long as we want to," he said Thursday in an e-mail to The Associated Press.

The office of the Supreme Court's registrar could not be reached despite several phone calls seeking confirmation.

Smith, who moved to the Bahamas while pregnant with her nearly 3-month-old daughter, has remained secluded in the house since her 20-year-old son Daniel died under mysterious circumstances at her hospital bedside on Sept. 10.

The 39-year-old former Playboy playmate has claimed that Thompson bought her the nearly US$1 million house as a gift. Thompson, who had a brief relationship with Smith, says it was a loan.

Knowles said he gained authority to file the judgment with the Supreme Court after a two-week deadline expired on Monday, and he asked Smith in writing to vacate by Thursday. If she does not comply, they will ask court officers to remove her from the property, he said.

"It's bringing things near to an end," Knowles said.

A private pathologist concluded that Daniel Smith died from a lethal combination of methadone and two antidepressants. Official toxicology results have not been publicly released.

Bahamian police completed their investigation into his death and submitted their report six weeks ago, but authorities have not indicated whether they will convene a jury inquest.
