Divorce attorney Laura Wasser has represented high-profile clients like Kim Kardashian, Britney Spears and Ariana Grande. Regardless of who they are, Wasser told CNBC Make It last year, the No. 1 reason she sees people get divorced is the same: “They don’t communicate.”

Throughout a marriage, “you have to talk about stuff,” says Parima Pandkhou, divorce attorney and Wasser’s colleague at Wasser, Cooperman & Mandles. “If you sweep it under the rug, it just gets bigger and bigger.”

And it helps to build that habit of open communication before you sign a marriage license.

To get started, Pandkhou and divorce and family law attorney Padideh Jafari recommend bringing up these three questions before you tie the knot.

“Finances is still one of the top three reasons why people get divorced,” Jafari says. So, it’s important to address that early on.
