(CNN) When high-profile CEOs with mega wealth get divorced, many assume it will be a contentious, drawn-out drama.

But it doesn't have to be.

In a statement Wednesday announcing they were ending their marriage , Jeff and MacKenzie Bezos made clear they were parting amicably. "We feel incredibly lucky to have found each other and deeply grateful for every one of the years we have been married to each other. If we had known we would separate after 25 years, we would do it all again."

Attorney Laurence Hirsch, who represents clients in high-net-worth divorces at Jaburg Wilk in Arizona, said he can tell pretty quickly which couples are likely to benefit from mediation and avoid battling it out in a courtroom. The telltale sign? "Both sides come to their lawyers and say this just didn't work. I don't hate my spouse or regret marrying them," said Hirsch, who is not involved with the Bezos divorce.

Mutual respect isn't the only factor that might help a couple avoid drama. When there is simply so much money, there's little need to argue.
