EXCLUSIVE: Kevin Costner's estranged wife Christine remains at their $145M coastal California compound as she refuses to leave following divorce filing in violation of their prenup ... as inspectors seen on scene

Kevin Costner's estranged wife Christine Baumgartner was spotted at their $145 million beachfront compound in Carpinteria, California Wednesday, amid news that he has taken legal steps to get her to leave the home in the wake of her divorce filing last month.

The Oscar-winning actor, 68, said that under the terms of their prenuptial agreement, Baumgartner, 49, had a 30-day period to move out of the house he owns following her May 1 divorce filing, Radar reported Tuesday after reviewing legal docs in the case.

The Dances With Wolves actor-director told the court he believes that Baumgartner is remaining in the home to persuade him to give into 'various financial demands' she is making in the wake of the split.

In addition, a group of property inspectors were seen on the premises Wednesday, which could be connected to the actor's recent decision to mortgage a piece of his property to fund his upcoming film franchise Horizon.

Costner said he has already provided Baumgartner with $1.45 million under the terms of the prenup, providing ample funds for her to procure a new place to live.

Baumgartner was pictured leaving a Montecito, California Bank of America branch as news spread of the divorce-related dispute on Wednesday.

Baumgartner, who has past worked as a model and handbag designer, was seen checking out a phone as she walked down the steps of the financial institution.

She was pictured behind the wheel of a gray Range Rover as she headed from the bank to Carpinteria, California, compound Wednesday.

Baumgartner, who shares three children with Costner - sons Cayden, 16, and Hayes, 14, and daughter Grace, 13 - appeared to have a passenger in the luxury vehicle while making the trek in the well-heeled coastal community.

Amid the divorce and property dispute, the Yellowstone star has told the court that he would be amenable to further financial arrangements in an effort to get her to leave the home.

Costner said in court docs that he's amenable to 'contribute as part of his child support obligations $30K per month for a rental house, and is willing to advance another $10K for her moving costs.'

He said in court docs that he is the sole owner of the three family homes; and per the prenup they signed when they wed in 2004, Baumgartner agreed to leave the homes and take her possessions in the event of a divorce.

Costner has a vast real estate portfolio, highlighted by a 10-acre beachfront compound in Carpinteria, California that is worth an estimated $145 million.

The home is perched on a clifftop and boasts ocean views. Costner originally designed a dream home with a pool and guest house.

Due to family commitments and spending time at his Aspen home, he never got around to redeveloping the site.

The compound includes 500 feet of private beach, surrounded by cliffs, and the actor has built an apparent recreational house on the property which is surrounded by outdoor furniture and umbrellas.

Originally, the parcel of land came with a polo practice field which baseball aficionado Costner converted to a baseball field. The home also boasts views of the Santa Barbara mountains, several islands and its own horseback riding trail.

Costner had already owned a home on the beach in Carpinteria, purchasing a 17-acre parcel of land complete with a modest two-bedroom, two-bathroom ranch in 2006 for $28.5 million. Costner noticed the home when he saw a for sale sign while jogging by.

In 2007, the JFK star sold seven acres of the land to a neighbor, but combined his homes to create one seamless estate.
