The former Game Of Thrones star, who was served with divorce papers this month after four years of marriage to Jonas, said in her petition that the couple had planned to raise their daughters in her native England.
It also said that the girls, aged three and one, “are both fully involved and integrated in all aspects of daily and cultural life in England”.
Best known for playing Sansa Stark in the hit fantasy series, Turner filed her petition in federal court in New York under the child abduction clauses of the Hague Convention, an international treaty aimed at compelling the return of a child taken from their country of “habitual residence”.
Turner alleges that she and Jonas made a mutual decision to raise their daughters in England and to relocate there in April of this year.
During part of August and September, while Jonas began a tour with his band the Jonas Brothers in the United States, Turner would be working long hours filming a television series in England. So, Turner said she and Jonas had agreed that the children would travel with Jonas and a nanny.
The plan was apparently for Turner to travel to New York after filming wrapped on 14 September to collect the children, but in the meantime “the breakdown of the parties’ marriage happened very suddenly,” Turner claimed.
According to Turner, Jonas filed for divorce in Florida on 1 September and she learned about it through the media four days later.
The former couple then issued a joint statement on their Instagram accounts on 6 September saying they had mutually decided to amicably end the marriage.
Turner says she and Jonas saw each other on 17 September — and she asked him for the children’s passports so she could take them back to England, but Jonas refused to turn over the passports of the girls, who were born in the United States, and have dual US and British citizenship.
Per the court filing, the girls are temporarily living with Turner in a Manhattan hotel. The Jonas Brothers were scheduled to perform in Philadelphia on Thursday and in Baltimore on Friday.
Jonas said in a statement that he is “seeking shared parenting with the kids so that they are raised by both their mother and father” and that he is “okay with the kids being raised both in the US and the UK”.
“This is an unfortunate legal disagreement about a marriage that is sadly ending,” he added. “When language like ‘abduction’ is used, it is misleading at best, and a serious abuse of the legal system at worst.”
Jonas said he did not surprise Turner with divorce papers but rather filed for divorce after what he described as “multiple conversations with Sophie”.
The pair first began dating in 2017, and a year later announced their plans to tie the knot. They eventually married in 2019.
