Adrienna and Paul listed the 20,000 sq. ft. home recently -- a French chateau-style estate featured on the reality show with 8 bedrooms and 11 baths.
Maloof and Nassif purchased the home in 2004 for $12.7 million. It's now listed for $26 million, more than double what they bought if for.
Sources close to Adrienne tell TMZ, she okay'd the listing because "she just needs to make a change."
People close to Paul say it was a joint decision to sell the house -- and has nothing to do with Adrienne obtaining temporary child custody.
You'll recall, Adrienne won temporary custody of her and Paul's three boys yesterday, after claiming Paul choked one of them. Paul has denied the allegations.
