Wilde shares her two kids — son Otis and daughter Daisy, 6 — with ex Jason Sudeikis, 48.

This past week, the former couple settled their custody case, with Sudeikis required to pay $27,000 a month in child support. According to court documents obtained by the Daily Mail on Monday, the exes are set to share joint custody of their two children on what is described as a "week-on, week-off basis."

The Ted Lasso actor, 48, has been ordered to pay a child-support sum of $27,500 per month to Wilde, the court records show. The amount comprises $10,300 for Otis and $17,200 for Daisy.

Per the papers, Sudeikis will also have to cover 25% of Wilde's childcare costs, on top of the $27,500 monthly payment.

Sudeikis' estimated income was $10.5 million, while Wilde made about $500,000, according to the court documents.

At the time, a rep for Sudeikis declined to comment on the record, while a rep for Wilde did not immediately respond to PEOPLE's request for comment.

For Mother's Day this year, Wilde received a sweet card from her daughter Daisy, which she shared on her Instagram. The fill-in-the-blank prompt of the card began, "Because of you, I believe I can," to which the first-grader wrote, "fly."

"Mom job = done," Wilde captioned the shot. "Happy Mother's Day to all of us❤️."
