Kevin Costner ups child support offer to ex to $52,000 a month – but she says she still needs 6 figures monthly to raise their children

• Kevin Costner offered his estranged wife about $52,000 a month in child support.
• Christine Baumgartner's team said in new filings that $217,000/month was a fair amount for child support.
• A judge ruled Wednesday that Baumgartner and the kids had until the end of July to move out.

Kevin Costner's estranged wife slammed the actor's latest child support offer, claiming that she needs far more to support the life of luxe their children are used to.

In new filings, Costner's estranged spouse Christine Baumgartner balked at Costner's latest child support offer of about $52,000, pointing to his monthly income. Baumgartner, who was just ordered by a Santa Barbara judge to move out of their shared compound by the end of July, argued that she needs at least six figures to support herself and their three children.

In a declaration filed on Wednesday, Baumgartner's attorneys claimed that Costner spends "$240,000 per month on himself" and their three kids when they are with him.

She claimed that that when the couple rented out their guest house, it listed for $65,000 a month, less than what Costner is offering for child support.

Baumgartner said that in order for a transition to be seamless for the kids, they would need to move somewhere similar to the luxe life they are used to.

"They are entitled to have a home that is somewhat comparable to one of the three multi-million-dollar residences which make up the Beach Club Compound," Baumgartner wrote in a new declaration. "I cannot provide housing and care for the children at anything close to their accustomed lifestyle with the $51,000/mo. Kevin proposes to pay in child support."

A forensic financial analyst hired by Baumgartner said that $217,300 per month in child support was fair, given Costner's income, per the new filings.

"We believe that $217,300 is the correct figure because, historically, the children have spent far more time with Christine than with Kevin due to Kevin's out-of-town work schedule," the filings state.

Previously, Baumgartner accused Costner of low-balling her with a $30,000 a month child-support offer and leaving her with limited funds as a stay-at-home mom with no income by canceling a credit card.

In filings this week, Costner said he imposed the limits after Baumgartner used the cards to spend $45,000 for a Los Angeles-based lawyer and $40,000 for her Santa Barbara-based attorneys without his knowledge.

Representatives for Costner and Baumgartner did not immediately return Insider's requests for comment.

In previous filings, Baumgartner claimed that Costner made $19 million last year and that he had covered the family's $6.6 million expenses. After Baumgartner filed for divorce last month, Costner filed a motion to evict her from their marital home, citing a clause in their prenuptial agreement that he said gave her 30 days to move out after divorce proceedings began.

The "Yellowstone" actor said that he paid his estranged spouse $1 million for a new house and that he had offered to pay the mortgage, insurance, and taxes for a year, per court documents.

Baumgartner accused Costner of trying to move her and the children out of the house before a child-support order was in place. Costner denied this.
