The Bristol Rovers manager allegedly left his wife with a head injury in an attack in Kew, London.
Former Premier League footballer Joey Barton has denied attacking his wife, leaving her with a head injury.
The Bristol Rovers manager appeared at Wimbledon Magistrates Court earlier via videolink.
The 38-year-old was charged with assaulting Georgia McNeil by beating in Kew, London, on 2 June.
Mr Barton, of Widnes, Cheshire, played for Newcastle United, Manchester City, Queens Park Rangers and French side Olympic Marseille.
Mr Barton spoke only to confirm his name, date of birth and address.
He was released on unconditional bail until his trial at the same court on 16 December.
Bristol Rovers, who were relegated to League Two last season, declined to comment while legal proceedings were ongoing.
