A Timeline of Tom Brady and Gisele Bündchen's Marital Struggles Before Their Divorce

After a year of increased marital struggles, Gisele Bündchen and Tom Brady have finalized their divorce.

Sources tell PEOPLE that they will both file in Florida on Friday morning.

"The settlement is all worked out," a source with knowledge of the situation tells PEOPLE. "They've been working on the terms this whole time."

The source adds: "They agreed to joint custody of the kids."

Below is a timeline of what has happened between Brady and Bündchen since the quarterback announced his (brief) retirement from the NFL.

January 29

ESPN's Jeff Darlington and Adam Schefter are the first to break the news that Brady planned to retire following a playoff loss to the Los Angeles Rams in January. The pair said Brady's decision fell on a number of factors, including "family and health." Brady did not speak on the news until three days later.

February 1

In an Instagram post, Brady confirmed his retirement, saying he could no longer "make that competitive commitment anymore."

"I have loved my NFL career, and now it is time to focus my time and energy on other things that require my attention," he wrote, in part. "I've done a lot of reflecting the past week and have asked myself difficult questions. And I am so proud of what we have achieved."

Bündchen congratulated Brady with a post on social media.

"So many memories! When I met you over 15 years ago, I didn't know the first thing about football. But cheering for you and seeing you do what you love most made me learn about this wonderful game to the point that I seriously believed I knew more than the referees!" she wrote.

"We always had a special champions playlist for every drive on our way to the game," she added. "As a family, we always prayed for you, celebrated and supported you in every game, cheered every win and suffered with every loss."

Brady tells PEOPLE that returning to the NFL will be his "greatest challenge yet," though he admits he knows he is "at the end" of his career.

"I want to go out there and have my best year yet," he added. "It requires a lot of time and focus and energy, just like everything, every detail matters. Everything's important. There are zero compromises to getting the result that we want. And it's got to be 100 percent effort by everybody to accomplish our goal."
