If the agreement is violated, the documents state that the court has the right to “take or cause to be taken measures under Federal or State law, as appropriate, to protect the well-being of the child involved or to prevent the child’s further removal or concealment before the final disposition of the petition.”

Monday’s development comes days after Turnerfiled a lawsuit against the boy band memberrequesting that their daughters be returned to England. In the lawsuit, Turner alleged that Jonas was withholding their passports and called for “the immediate return of children wrongfully removed or wrongfully retained.”

“After multiple conversations with Sophie, Joe initiated divorce proceedings in Florida, as Florida is the appropriate jurisdiction for the case," the statement read in part. “Sophie was aware that Joe was going to file for divorce. The Florida Court has already entered an order that restricts both parents from relocating the children. Sophie was served with this order on September 6, 2023, more than two weeks ago.”

The singer and the formerGame of Thronesstar were married for four years whenJoe filed for divorce on Sept. 5. A source who knows the former couple told PEOPLE at the time that the divorcedid not come as a “surprise” to those around them.
