On May 1, 2023, Christine Baumgartner filed for divorce from Kevin Costner, citing irreconcilable differences and listing April 11 as the date of separation. The filing came roughly eleven weeks after a video the couple had posted of themselves laughing together at home, unboxing Costner’s Golden Globe for his role in Yellowstone. In February of that year, storms had closed the roads out of Santa Barbara, so instead of attending the ceremony, the actor had stayed home in Montecito, where his wife of eighteen years turned the living room into a private celebration for two. Costner filmed the moment himself and put it online.
It looked like the kind of clip that proved a long Hollywood marriage could actually work. It would instead become the last clean image anyone had of the two of them as a couple. Costner had been with Baumgartner since 1998 and married her in 2004 at a ceremony on his ranch outside Aspen. Together they built a blended family in Carpinteria: Costner’s four children from his earlier marriage and the three they shared, Cayden, Hayes, and Grace.
By the time Yellowstone had returned Costner to the center of American television in his sixties, Baumgartner had become part of the story of his comeback. The contrast with his first marriage, which had ended in one of the most expensive and publicly dissected divorces Hollywood had ever seen, made the second marriage look like proof that he had gotten it right. That image held until the filing. Costner did not contest the split.
The next day, on May 2, he filed his own response, citing the same grounds and requesting joint custody of their three children. There was no denial and no delay. Whatever had gone wrong, both sides had already accepted that the marriage was over. The real fight was about what came after, and the terms of that fight had been written nearly two decades earlier.
In 2004, before their wedding, the couple had signed a prenuptial agreement. It was not vague. It listed dollar amounts, deadlines, and property lines with the precision of a business contract. Under its terms, Costner had agreed to pay Baumgartner $100,000 upon their marriage and another $100,000 on their first anniversary, both paid as promised.
Should she file for divorce, she was due an additional one million dollars, $200,000 toward a new home deposit, a year of property taxes and insurance, and a baseline of $30,000 a month in child support before any further negotiation. One clause covered the home in Carpinteria, the house Costner had bought in 1988, sixteen years before Baumgartner entered his life. If the marriage ended, she had thirty days from the filing date to move out. The fight over that house was never a spontaneous argument.
It was a contract clause reaching its deadline, a deadline both of them had agreed to long before either could imagine the day it would actually apply. Baumgartner did not leave on schedule. By early June, Costner and his attorney filed documents asking the court to order her out of the residence, stating that she had ignored repeated requests to go despite his offers to help financially with the move. In a declaration attached to the filing, Costner explained why the house mattered to him personally, pointing back to his first divorce and the experience of separating without a home base to return to.
It was a rare, almost tender note in the paperwork, an old wound from one marriage shaping the terms of another one ending, sitting directly beside a hard legal push to remove his wife from a house she had lived in for nearly two decades. A judge ordered Baumgartner to vacate the property by the end of July. She left weeks past the deadline the prenup had set, and the house fight was over. For a few weeks that summer, an eviction order attached to a movie star’s name became a headline, stripped of the nuance behind it.
But the house dispute had never been the hardest part of the divorce. The moment it ended, the money became the battle. Baumgartner’s legal team requested $248,000 a month in child support, arguing that it was what the three children needed to maintain the life they had always known. Costner’s side called the figure unrealistic, pointing to his declining income after stepping away from Yellowstone.
He initially offered around $75,000 a month, later revising the figure down closer to $52,000 as the case intensified. In July, a judge set a temporary figure of $129,755 a month while both sides kept arguing. Costner’s attorneys accused Baumgartner of stalling, of dragging the case out by claiming she had not fully understood terms in the prenup she had signed. One filing called it gamesmanship of the worst sort.
This was not the language of two people quietly working out custody. It was litigation language built for a judge. Costner appeared in person at several hearings, an unusual choice for someone of his stature, which one celebrity divorce attorney described as a deliberate sign of respect toward the process. Whatever the intent, it meant the actor sat through open court proceedings while strangers argued over how much his three children were owed to maintain their accustomed lifestyle, a phrase that appeared unedited in the actual filing.
This might have remained an ordinary, expensive custody fight, but the money dispute had no fixed ceiling. The house fight had a contract with a deadline everyone had already signed years before. The money fight could run as long as either side’s lawyers wanted it to. For four straight months, it did.
As part of financial discovery, Baumgartner’s team requested documents relating to Costner’s finances, including any expenses connected to extramarital relationships. His attorneys responded that he had none to disclose because none existed. The filing did not stop there. It also stated that Costner could not say for certain whether Baumgartner had been faithful during the marriage or whether money he had paid had ever gone toward an affair.
This was not an accusation. It was something colder: a legal record of a nineteen-year marriage in which, by the end, one spouse could not say with confidence what had actually been true. Within weeks, Baumgartner was photographed on a trip to Hawaii with a man named Josh Connor, a financier who had lived down the street from the Costners before the split. She would later testify that he was not her boyfriend at the time and explained a $20,000 payment from him as help during a stretch when she had limited access to money.
Whether that relationship began before or after the separation remained disputed. Tabloid sources later claimed Costner had suspected something for a while before the filing, but those claims came from unnamed insiders, not from anything entered in court. What was verified was simpler: a marriage that ended with both people quietly questioning what the other had been doing, without either one ever proving it in writing. This was not Costner’s first expensive ending.
His marriage to Cindy Silva, his college sweetheart and the mother of his first three children, dissolved in 1994 after sixteen years in a settlement that reportedly ran close to $80 million, one of the largest in celebrity divorce history at the time. Rumors had circulated that on-screen chemistry with a co-star had strained things at home, tied loosely to the release of his 1987 film No Way Out, but Costner never confirmed that account. The settlement was documented. The pattern, if there was one, was that both times the legal fight outlasted the marriage itself.
In September 2023, four months after the filing, Costner and Baumgartner reached a settlement. Their joint statement called it an amicable and mutually agreed resolution of all issues in the divorce. It was worth sitting with that word next to everything that had come before it: the eviction order, the stalling accusations, the fidelity questions logged into the public record. Every stage of this divorce that looked resolved turned out to be a checkpoint, not an ending.
The house was resolved, then the money took over. The money was resolved, and then it still took five more months of paperwork before any of it became legally final. California requires a minimum six-month waiting period after filing before a divorce can be finalized. There were smaller matters left to close, including whether the two would need to complete a court-mandated co-parenting class.
They did not. On February 15, 2024, nine months and two weeks after Baumgartner first filed, Judge Thomas Anderle signed the judgment. The final child support figure landed at $63,209 a month, well below her original request and above his lowest offer. The court found the marital settlement agreement fair and reasonable and approved it in full.
Baumgartner has since remarried, exchanging vows with Josh Connor in October 2025 at a private vineyard outside Santa Barbara with all six of their combined children in attendance. Costner has kept working, premiering the first chapter of his Horizon films the same year his divorce was finalized and telling reporters afterward that when a life that long with somebody unravels, there is no version of it where anybody actually wins. The house in Montecito still stands where it always did. The living room where a Golden Globe was unboxed for an audience of two has not moved an inch.
What is different is harder to see from the outside: a driveway only one of their cars pulls into now, and a front door that for thirty days in the summer of 2023, a judge had to order somebody to finally walk through.
