The former couple’s focus will remain on their two daughters, Olive, 3, and Frankie, 2 – and those close to the family believe they will continue to work together to do what is best for them as they figure out the next steps of their lives.
“They fundamentally agree on everything when it comes to their girls,” a family source previously told PEOPLE.
Barrymore, 41, and Kopelman, 39, announced their separation in April after nearly four years of marriage, saying that while they may no longer be a couple, they will always be a family.
“Sadly our family is separating legally, although we do not feel this takes away from us being a family,” the former couple told PEOPLE in an exclusive statement. “Divorce might make one feel like a failure, but eventually you start to find grace in the idea that life goes on.”
“Our children are our universe, and we look forward to living the rest of our lives with them as the first priority.”

The family has been living in New York City, and sources told PEOPLE they will keep their home base in the Big Apple, where Olive is enrolled in preschool, for the foreseeable future.
“I would suspect that these young people would want to have a joint custody arrangement,” Marilyn B. Chinitz, a Manhattan-based divorce attorney, previously told PEOPLE. “And because [the kids are] small at this point and they’ve not yet been in school, they have that flexibility.”
Despite their split, Barrymore remains close with her ex’s family.
Kopelman’s sister, Jill Kargman, told fans at a Tribeca Film Festival screening that that she and Barrymore are “sisters forever.” Barrymore even guest stars on her former sister-in-law’s Bravo show Odd Mom Out, playing the next-door neighbor to Kargman’s character, Jill Weber.
“[Barrymore] was a really good guest star. Wonderful. It was fabulous,” Kargman told PEOPLE. “She lives on the Upper East Side, so she lives it. She’s doing it. Her daughters are in the school that my kids went to. She’s in it, and it’s with a wink and a smile. And she did a beautiful job.”
An insider previously told PEOPLE that the couple “tried to work through things for some time,” before finally deciding to end the marriage. “This was not an overnight decision. They both really wanted to make it work.”
While a family source said Kopelman is “saddened” by their split, the two “really are friends,” says a source close to the actress. As for Barrymore, “she’s disappointed,” adds the insider. “But she’s optimistic for the future.”
