The Take That star and his spouse are being sued by their former personal assistant Gilles De Bonfilhs over claims she made him uncomfortable by walking around naked and boasting about her sex life. He also alleges they "wrongfully terminated" his employment in January last year (15).
According to the Press Association, at a hearing in Los Angeles on Thursday (17Nov16) lawyers for De Bonfilhs filed a motion attempting to compel the couple to give evidence.
The presiding Judge Deirdre Hill adjourned the case until 9 December (16), when she will rule on whether Williams and his wife, a panellist on British TV show Loose Women, will have to give a deposition ahead of a trial set for 16 February (16).
Williams and his wife, who were not in court for the hearing, deny their former assistant's allegations and have countersued for fraud and false invasion of privacy in a lawsuit which calls his claims "despicable lies".
The couple married in 2010 and have two children, Theodora Rose, four, and two-year-old son Charlton Valentine.
In their countersuit they claim De Bonfilhs was fired after three months for his "total job abandonment and numerous other instances of wrongful conduct".
De Bonfilhs is seeking more than $25,000 (£15,625) in damages from the couple for embarrassment, humiliation and mental and emotional distress.
Williams showed few signs of letting the legal proceedings worry him when appearing at Germany's BAMBI international media awards on Thursday.
The Rock DJ singer, who performed and collected the Music International Award at the ceremony, lived up to his cheeky reputation by pretending to bury his head in presenter Barbara Schoeneberger's chest while on stage.
