Brad Pitt has a good chance of winning a lawsuit in which he says his ex-wife Angelina Jolie sold her part in their Chateau Miraval estate behind his back, according to a legal expert.

The "Ad Astra" star did not get first dibs on the "Maleficent" actress's share of their $164 million French home. 

Pitt sued Jolie over the sale, saying that when they bought the luxury property in 2008, they vowed never to sell their individual stakes without the other person's permission. 

In a complaint obtained by Fox (via The News), Pitt stated that the house was purchased as an investment to be shared with their children, whereas the vineyard is a family business. 

Now, Pitt is saying that Jolie raced to sell the mansion without his permission. 

It is the same location where the former power couple married in a private ceremony attended only by their six children in 2014. 

The 58-year-old A-lister now alleges in a legal lawsuit for breach of contract against the 46-year-old humanitarian that she violated the pledge by selling her stake in a Luxembourg-based spirits producer controlled by a Russian oligarch. 

According to court records, the "Tomb Raider" actress denied Pitt the consent right that "she owed him" as well as the "right of first refusal that her business organization gave him." 

It goes on to say that Jolie sold her stake knowing that the Russian tycoon and his partners would dominate the firm - a business that Pitt had devoted himself to for years, even if it meant jeopardizing his investment in the estate. 

According to the "Once Upon a Time in Hollywood" actor, Jolie now attempts to "recover discovered windfall riches for herself while inflicting gratuitous pain" on him as a result of the "purported transaction."

However, according to certified family lawyer David Glass, who is only familiar with the case but not involved in it, Brad Pitt's oral contract theory isn't as strong as he may believe, but he continues to maintain that his claims that he and Jolie, through corporate negotiations centered on the sale of her stake to Pitt, prove that an agreement did occur. 

The lawyer believes that it would also carry more weight in court. 

Glass said Jolie was aware of the risks associated with selling her part in the estate, and that her argument about Pitt running to express his grievances to the press is a "weak" attempt to persuade the court to rule in favor of public opinion. 

He also stated, "Angelina's counsel are attempting to circumvent the law... which will ultimately fail, but may alter public opinion in the short run."
