Kevin Costner said he reduced his estranged wife's credit-card limit to $30,000 after he discovered she charged him for $100,000 worth of legal and accounting services: court docs

• Kevin Costner accused his estranged wife of funding her legal services in their divorce on his dime.
• The "Yellowstone" star said he lowered credit-card limits after she used them without telling him.

Kevin Costner has refuted his former partner's allegation that he canceled her credit cards after she filed to divorce him.

The "Yellowstone" star said in a legal declaration last week that he was forced to curb the spending of his estranged wife, Christine Baumgartner, after she racked up six figures worth of legal and accounting fees without his knowledge on credit cards he pays for.

"Christine says I have not maintained the status quo because I cancelled one of her credit cards and because I put (a large) limit on the use of the credit card she uses," Costner said in a June 30 declaration, which was obtained by Insider.

"I agreed to maintain the status quo with respect to our children. I have done so. I have continued to pay for all of the children's expenses since Christine filed for divorce. Christine does not claim that the children's expenses have not been paid."

Last month, the actor said he offered to contribute $65,000 toward Baumgartner's legal fees — but he said her lawyers never responded.

Costner said he was forced to limit her access to his credit cards after Baumgartner used them to pay $45,000 for a Los Angeles-based lawyer and $40,000 for her Santa Barbara-based legal team.

She also charged $10,000 for the services of a forensic accountant and another $10,000 for a separate forensic accountant whose services she no longer planned to utilize, Costner alleged in his declaration.

"It was then that I made the decision that there needed to be some reasonable limitation on the use of the credit cards," Costner said in court papers. "My lawyer gave her lawyers written notice."

Lawyers for the former couple did not immediately respond to a request for comment.

Baumgartner, a 49-year-old handbag designer who said in court papers she was unemployed, filed for divorce from Costner in May, citing "irreconcilable differences." The couple were married for 18 years and are parents to Cayden, 16, Hayes, 14, and Grace 13.

The pair are set to appear in a California court later this week, where a judge is set to rule on Costner's motion to enforce a provision of their prenuptial agreement forcing her to move out within 30 days after they divorced.

Baumgartner said in court documents that she would move out by the end of August — but only if the "Field of Dreams" star paid her $248,000 a month to maintain their children's lifestyle. Costner said Baumgartner's demand was absurd and accused her of inflating the figure to maintain her luxury lifestyle.

The increasingly acrimonious divorce comes amid some drama in Costner's professional life, too. Deadline reported in February that a behind-the-scenes feud between the actor and "Yellowstone" cocreator Taylor Sheridan over shooting schedules was holding up production on the show's fifth season.

While Costner has yet to address the claims, it was announced in May that the drama would be ending later this year with the conclusion of its fifth and final season.
