Christine Quinn’s estranged husband, Christian Dumontet, is seeking sole ownership of their once-joint home in Los Angeles.
Dumontet, 47, filed court documents on Friday, April 17, and obtained by Us Weekly, asking for control over the property in order to sell it and pay off the mortgage.
According to Dumontet, he wants to sell the house to “stop the ongoing financial loss associated with maintaining a non-income-producing asset.”
Dumontet said he purchased the residence months before he married Quinn, 37, in 2019, and now has a $3.5 million balance on his mortgage loan. He alleged the house has cost him $400,00 a year to maintain.
“This is not sustainable,” Dumontet wrote in his filing. “I require immediate court intervention to stop this financial hemorrhaging.”
Dumontet and Quinn, who share 4-year-old son Christian, separated in 2024. Dumontet was ordered to move out of the house after the Selling Sunset alum was granted a temporary restraining order in March 2024 after Dumontet’s two arrests. (Dumontet was arrested following an alleged domestic violence altercation, released on bond and arrested hours later for breaking the TRO.)
In Dumontet’s April court documents, he claimed that he wasn’t able to “regain the ability to act with respect” to the house until September 2025. Once his home access was restored, Dumontet began repairing, renovating and preparing the house for sale that allegedly cost him thousands of dollars.
Dumontet, who stated that he has since moved to France with his new girlfriend and their 12-month-old son, now wants to sell the house to use the funds to cover his reported debt.
In the filing, Dumontet stressed that neither he nor Quinn live in the house and it doesn’t generate any income.
“[Quinn] has never made any financial contribution to the [home], whether toward the purchase price, mortgage payments, carrying costs, maintenance, or otherwise,” the filing reads, with Dumontet allegedly paying “exuberant costs to keep” the home that caused him “irreparable financial harm.”
Christine Quinn shot to fame showcasing luxury dream homes on Selling Sunset, but behind closed doors her own life was turning into a nightmare. According to newly obtained police records, Us Weekly can exclusively reveal that 18 emergency calls were made to the Los Angeles Police Department over the last five years regarding alleged incidents […]
Dumontet stated that Quinn is “not on the hook” for any debt the house accumulates.
“I alone am suffering this harm, and without court intervention, I will continue to,” he added.
Dumontet’s request for an emergency order was denied while the house went back on the market Saturday, April 18, for almost $7.5 million.
Us Weekly has reached out to Quinn for comment.
Amid her divorce, Quinn moved to Texas with her son.
“I am really, really grateful to be living here,” the reality TV star told People in January 2025. “[It’s a blessing to] be close to my family. I have a sister who lives really close to me, and my son has a cousin.”
She added, “I found a wonderful house. I would say it’s, like, 60 percent done, but there’s still some things that I want to do and really take it to the next level because I love interior design.”
