Sir Paul McCartney and estranged wife Heather Mills McCartney have returned to the High Court in London for their ongoing divorce proceedings.
Reports that a settlement had been reached were denied in January
The hearing, which began on Wednesday, is being held in private in Court 47 in the Queen's Building, the part of the court reserved for family hearings.
Held before Mr Justice Bennett, this is believed to be a preliminary hearing before the start of the main action.
Sir Paul reportedly looked cheerful as he arrived at the court by car.
Lady McCartney, who arrived shortly before, said nothing as she arrived for the closed-door session towing a case full of legal documents.
The former model, 38, and the 64-year-old musician separated last May after four years of marriage and began divorce proceedings in July.
In cases held at the Queen's Building, the names of the parties are normally posted outside the court with the case number.
However, the McCartneys' hearing - reportedly scheduled to last for a day and a half - was identified only by its number.
At issue in what has become an acrimonious separation is the custody of their three-year-old daughter Beatrice and Sir Paul's reported £800m fortune.
In January lawyers for the couple denied Lady McCartney had accepted a divorce settlement worth £32m.
