Litigation is starting to heat up between celebrity chef Bobby Flay and actress Stephanie March after Flay filed for divorce earlier this month. According to reports, the points of contention have to do with terms of their prenuptial agreement and their house.

TMZ reports that the 50-year-old restaurateur is paying March $5,000 a month in support payments, every month for five years, per the conditions of the prenup they signed when they got married in 2005. The pair have no children together. Additionally, Flay reportedly will retain ownership of their Amagansett, New York, house, valued around $8 million. He’d provide the “Law and Order: SVU” star with a $1 million buyout and a $50,000 stipend to clear her things out of the home, but March and her lawyers are saying it’s an unreasonable arrangement.

Her lawyers claim that the Food Network star is worth an estimated $20 million, and she feels she was an important part of his success. The plot thickens with a new report from TMZ saying that Flay has canceled her credit card in the hopes of strong-arming her into leaving the house. But the house is very important to March: When her mother was diagnosed with cancer, she moved her into the couple’s shared home to look after her, according to E! Online. Per the New York Daily News, Flay’s work schedule keeps him away from home for extended periods of time.

"We regard the support provisions of the pre-marital agreement as unenforceable (not to mention morally reprehensible),” March’s lawyers told TMZ in a statement, revealing they’d sent back the first $5,000 monthly check.

March’s team may have some leverage. The couple’s marriage has been plagued by rumors of Flay’s infidelity for years. New York Daily News cites a controversy in 2010 when rumors circulated that he was having an affair with “Mad Men” star January Jones. And recent reports from Page Six mention his Food Network co-star Giada De Laurentiis in cheating rumors.

“They spent time together, they filmed a show together, they were never [romantically] involved,” Flay’s lawyer told the outlet about Giada in a statement. So far, no one from Flay’s camp has had anything to say about the $5,000 payouts or the canceled credit card.
