Christine Quinn’s estranged husband, Christian Dumontet, is searching for 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 to be able to sell it and repay the mortgage.
In line with Dumontet, he desires to sell the home to “stop the continued financial loss related to 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 home has cost him $400,00 a 12 months to take care of.
“This is just 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 maneuver out of the home after the Selling Sunset alum was granted a brief 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 capable of “regain the flexibility to act with respect” to the home until September 2025. Once his home access was restored, Dumontet began repairing, renovating and preparing the home on the market that allegedly cost him hundreds of dollars.
Dumontet, who stated that he has since moved to France along with his latest girlfriend and their 12-month-old son, now desires to sell the home to make use of the funds to cover his reported debt.
Within the filing, Dumontet stressed that neither he nor Quinn live in the home and it doesn’t generate any income.
“[Quinn] has never made any financial contribution to the [home], whether toward the acquisition price, mortgage payments, carrying costs, maintenance, or otherwise,” the filing reads, with Dumontet allegedly paying “exuberant costs to maintain” the house 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 right into a nightmare. In line with newly obtained police records, Us Weekly can exclusively reveal that 18 emergency calls were made to the Los Angeles Police Department during the last five years regarding alleged incidents […]
Dumontet stated that Quinn is “not on the hook” for any debt the home accumulates.
“I alone am suffering this harm, and without court intervention, I’ll proceed to,” he added.
Dumontet’s request for an emergency order was denied while the home went back available on the market Saturday, April 18, for nearly $7.5 million.
Us Weekly has reached out to Quinn for comment.
Amid her divorce, Quinn moved to Texas along with her son.
“I’m really, really grateful to be living here,” the truth TV star told People in January 2025. “[It’s a blessing to] be near my family. I even have a sister who lives really near me, and my son has a cousin.”
She added, “I discovered an exquisite house. I’d say it’s, like, 60 percent done, but there’s still some things that I need to do and really take it to the following level because I really like interior design.”
