Former Blackpool chairman Karl Oyston is suing the club – which is owned by his father Owen – in a dispute over wages.
Mr Oyston’s case has been listed as a two-day hearing at an Employment Tribunal in Manchester. The trial starts on Wednesday.
Karl Oyston’s sister, Natalie Christopher, replaced him as chairman and director of the club in February 2018.
And last week the League One club was put into receivership by the High Court, in a dispute between Owen Oyston and former director Valeri Belokon.
Karl Oyston, who turns 51 on Wednesday, had been chairman of the Tangerines since 1999.
The Employment Tribunal would not give detailed information about the case but confirmed it related to wages.
Karl Oyston’s ownership of the club has been eventful, having previously been sued by Blackpool fans for libel and also had to apologise to one supporter over an abusive text.
A number of fans have taken to boycotting the games for five years in protest at the way Mr Oyston and his dad have run the club.
After the club was put into receivership on February 13th, Owen Oyston was forced to pay former director Belokon £25million.
David Rubin & Partners are due to be confirmed as receivers of Blackpool this week in a move which could see Owen Oyston lose control of it.
The EFL vowed it would work with the newly-appointed receivers of Blackpool to ensure the club fulfils its fixtures next season.
The governing body must also make a decision on whether to dock Blackpool twelve points – the league’s penalty for going into administration – at a meeting on 6 March.
