The pair -- who officially separated in early April amid the coronavirus outbreak -- have been fighting in the courts over everything from custody agreements to marital funds and assets, and a lot of it has spilled out into the public sphere. So where did it all go wrong?
The couple tied the knot in June 2013 -- after first getting engaged in April 2011, calling it off three months later, and then recommitting to their engagement the following November. They also share three children -- 7-year-old son Camden, 5-year-old son Jaxon and 4-year-old daughter Saylor.
While their relationship has had its fair share of ups and downs, we're taking a look back at the time leading up to and since their split, and breaking down the legal battle brewing between the estranged pair.
Aug. 29, 2017 -- "Single Parent" Problems
In August 2017, Jay signed a one-year, $10 million deal to play for the Miami Dolphins, and Kristin revealed that she had no plans on uprooting the family and moving to Florida for the season. Kristin told ET's Katie Krause during a Facebook Live interview, "So, I'm a single parent for the next five months... It's a little chaotic, but in the best way." Kristin added that it "doesn't make sense to pack up the family just for five months."
"My kids are great," she added. "They're good kids for the most part. Of course we have our stuff, but it actually hasn't been as hard as I thought it was going to be, being a single parent. I have an amazing nanny, my mother-in-law is there with my kids right now, so I couldn't do it without them." Kristin also said that the kids were old enough that it was hard for their boys when Jay was working out of state. "They're old enough now, they get that Daddy's gone."
