Sophie Turner is suing Joe Jonas for the return of their two young children to the UK.
Court documents allege the Jonas Brothers singer is refusing to hand over the children’s passports, said NBC, Sky News’s US partner.
Jonas, meanwhile, has urged Turner to “reconsider her harsh legal position and move forward in a more constructive and private manner”.
“His only concern is the well-being of his children,” his representative said.
In another development, Turner was spotted out in New York last night with Taylor Swift, who also had a relationship with Joe Jonas.
It was confirmed earlier this month that the couple were splitting, describing the decision as “amicable” and “mutually decided” following “four wonderful years of marriage”.
The children are currently with Turner in New York, court documents said, with Jonas allegedly refusing to allow them to cross the Atlantic to England.
They also claim that Turner heard about Jonas filing for divorce through the media, a couple of weeks after they argued in mid-August.
While Jonas filed his documents in Florida on 1 September, Turner did not find out until four days later, the petition said.
However, the statement from Jonas disputed that claim, adding that the Florida court where the divorce was filed “restricts both parents from relocating the children,” and that Turner was aware of that order.
Jonas’s representative said he and Turner had a “cordial” meeting on Sunday in New York after she flew there to be with the children.
“Joe’s impression of the meeting was that they had reached an understanding that they would work together towards an amicable co-parenting setup,” the statement said.
“Less than 24 hours later, Sophie advised that she wanted to take the children permanently to the UK.
“Thereafter, she demanded via this filing that Joe hand over the children’s passports so that she could take them out of the country immediately. If he complies, Joe will be in violation of the Florida Court order.”
Turner’s court documents, filed in the Southern District of New York, said the couple’s children, born in 2020 and 2022, have been wrongfully retained in New York City since 20 September from “their habitual residence” in England.
They said the youngsters, who have dual citizenship, are “fully involved and integrated” in daily life in England, with the older child attending school, and both involved in playdates and cultural activities.
Turner has “never consented or acquiesced to the removal of the children from England”, the court documents said.
They said that Turner – who played Sansa Stark in Game of Thrones – and the singer made England their permanent home in April, partly because of a desire to have the children educated in the country.
They moved into a rented property in May and made an offer on a permanent home in July, with a plan to move in in December, the filing said.
Because Turner began filming a new drama series in the UK in May, they decided the children would travel with Jonas and a nanny as he kicked off a tour with the Jonas Brothers in the United States in late July, NBC reported.
The plan, according to the petition, was for the children to stay with Jonas and his extended family until Turner finished filming.
She was then apparently expecting to travel to New York in mid-September before returning to the UK with the children.
But that was before the divorce was announced.
