The actress, 27, and the DNCE singer, 34, arrived at the officers of Wilmer Hale in New York’s Financial District, where the two are expected to spend several days trying to hash out a divorce agreement.
Sophie has been staying at Taylor Swift’s home in the city while the affairs are going on.
Turner’s lawyer admitted they would be going ‘full hog’ to resolve their matter during the process.
A court previously told that Jonas requested 50/50 custody and a judge set a January 2nd date for a trial of decided the custody of the young girls.
Lawyers claim there will be multiple witnesses for both sides.
Neither Jonas nor Turner, one of the stars of Game of Thrones, were present but Turner joined the hearing via Zoom.
The hearing was the first at the court in New York but the split also involved the divorce cases in both Miami and the UK.
As many recall, Jonas filed for divorce back on September 1st with sources close to the singer claiming that the star was partying too much.
He filed for divorce two weeks later claiming their relationship was ‘irretrievably broken’ and sources close to the singer tried to portray Turner as partying too hard and leaving him looking after their daughters.
In court papers she claimed that the couple sold their home in Miami in March and that they bought a $9million home near Oxford, England, which they meant as their ‘forever home’.
Turner fired back accusing Jonas a member of the pop group The Jonas brothers, of refusing to hand over the girls’ passports so they could return to England with her.
The Game of Thrones actress also cited an international child abduction law as grounds for her children being with her.
Both parties agreed that the children would be remaining in New York City until the case is resolved.
Her lawyer Stephen Cullen told the court that there was ‘some difficulty’ between the two parties with regards to scheduling a trial to decide custody of the girls. Cullen said he wanted an ‘amicable resolution’ in the case in the quickest fashion.
