Kevin Costner Divorce Settlement: Prenup, Child Support, Home Fight

Kevin Costner’s divorce settlement with Christine Baumgartner, finalized on February 16, 2024, was governed almost entirely by the prenuptial agreement the couple signed before their 2004 wedding. Baumgartner received a $1 million lump-sum payment plus $200,000 toward a new home, and the court ordered Costner to pay $63,209 per month in child support for their three children. Costner kept his real estate holdings, including the roughly $145 million Carpinteria compound where the family had lived.¹²

What the Prenup Required

The 2004 agreement set the ceiling on what Baumgartner could receive if the marriage ended. On a divorce filing, Costner owed her a $1 million lump sum and another $200,000 to help her buy a new home, along with one year of property taxes and homeowners insurance on that home. His real estate, including the Carpinteria property he had purchased in 1988, remained his separate property. Baumgartner was required to vacate any Costner-owned residence within 30 days of a divorce filing, and the agreement included a waiver of spousal support.³

An in terrorem clause raised the cost of fighting the agreement: if Baumgartner challenged the prenup’s validity, she risked forfeiting the payments and property interests it provided. Costner had disclosed assets of roughly $102.7 million when the prenup was signed.⁴ In court filings, Costner tied the prenup to his 1994 divorce from first wife Cindy Silva, which cost him an estimated $80 million and left him without a home. “I never wanted this to happen again,” he said.³

The Fight Over the Carpinteria Home

Baumgartner filed for divorce on May 1, 2023, in Santa Barbara County Superior Court, citing irreconcilable differences and listing a separation date of April 11, 2023.⁵ The first flashpoint was the 1.4-acre bluff-top compound in Carpinteria. Costner’s team filed on June 9 arguing Baumgartner had overstayed the prenup’s 30-day move-out window and was refusing to leave “unless and until Kevin agrees to various financial demands.”⁶ Her attorney, John Rydell, countered that the move-out request was “all but nonexistent.”⁷

On July 6, 2023, Judge Thomas P. Anderle sided with Costner and ordered Baumgartner to “unconditionally vacate” the property by July 31, denying her request for an August 31 extension.⁷ She moved into a nearby rental for $40,000 per month.⁸

How the Court Set Child Support

Baumgartner’s initial request was for $248,000 per month, which her attorneys said was needed to maintain the children’s accustomed lifestyle. They cited 2022 family expenses of $6,645,285 excluding taxes, along with private schooling, frequent trips to Costner’s Aspen ranch, and the amenities of the Carpinteria compound.⁹¹⁰ By the hearing, that figure was lowered to $161,592 per month, based on a forensic accountant’s estimate that Costner’s average annual cash flow in 2021 and 2022 was roughly $19.2 million.⁸ Costner’s team called the demand “highly inflated and unsubstantiated,” arguing Baumgartner had allocated roughly 60 percent of her own personal expenses to the children.¹¹

The central dispute was whether Costner’s Yellowstone salary should drive the calculation. By Season 5 he was earning $1.3 million per episode.¹² Costner testified that this income was a “complete aberration” and an “unusually high level of income” he had not experienced before, and that using it as a baseline would be “unjust and inappropriate.”¹³

Judge Anderle had set temporary support at $129,755 per month in July 2023.¹⁴ After a two-day evidentiary hearing on August 31 and September 1, 2023, he cut that figure by more than half, ordering $63,209 per month. In a 17-page summary, the judge called Costner’s argument on the Yellowstone income “exceedingly convincing” and said anything above $63,209 per month would amount to “disguised spousal support.”¹⁵

On top of the monthly payment, the order required Costner to cover all health insurance and unreimbursed medical costs, private school tuition, extracurricular costs, and specific items including hunting club dues and their son Cayden’s car.²

Why the Prenup Challenge Collapsed

Baumgartner sought $885,000 from Costner to fund a challenge to the prenup’s validity. Costner’s attorney, Laura Wasser, called the request “nothing short of outrageous” and noted the court had already found the agreement enforceable.¹⁶ On September 6, 2023, Judge Anderle instead ordered Baumgartner to pay $14,237.50 of Costner’s legal fees, which he had incurred filing a motion to compel discovery responses tied to the prenup. “Discovery is not a game of chicken,” the judge said.¹⁷

Costner had earlier been ordered to advance $200,000 in attorney fees and $100,000 in forensic accounting costs to Baumgartner, both subject to reallocation at trial, and had previously provided $300,000 toward her legal expenses.¹⁴¹⁸

The in terrorem clause then became the real pressure point. The judge indicated he intended to enforce the prenup, and that if Baumgartner kept challenging it she could be required to repay Costner more than $1 million and cover his attorney fees.¹⁷ Within two weeks, the case settled.

The Final Settlement

On September 19, 2023, the couple issued a joint statement announcing an “amicable and mutually agreed upon resolution of all issues,” heading off a December trial.⁵ The specific financial terms were not publicly disclosed.¹⁸

What court records and reporting do confirm is that the settlement tracked the prenup. Baumgartner received $1.2 million from Costner, consisting of the $1 million lump sum and the $200,000 housing deposit. Costner kept the Carpinteria compound and the rest of his real estate. The $885,000 in legal fees Baumgartner had requested was not included.¹

The judgment was entered in Santa Barbara County court on February 16, 2024. The couple shares joint custody of their three children. Both were excused from a mandated co-parenting course, though the court kept authority to require it if future custody disputes arose.²¹¹³

What the Prenup Kept Off the Table

By 2023, Baumgartner’s attorneys alleged that Costner’s net worth had quadrupled during the marriage to roughly $400 million, with about $24 million in cash.⁴ His real estate alone included the Carpinteria compound at roughly $145 million, a 10-acre Santa Barbara property purchased for $28.5 million in 2006, and the 160-acre Dunbar Ranch in Aspen acquired for $30 million in 2000.¹⁹

Against those numbers, the prenup limited Baumgartner’s share of the split itself to the $1.2 million payout, with the ongoing $63,209 monthly child support and court-ordered child expenses sitting on top. The 1994 Silva divorce, which had no prenup and produced an estimated $80 million payout, is the point of comparison Costner himself invoked.³
