The former owner of York City FC is taking the current owners to court alleging breach of contract.
Jason McGill has served a writ against York City Football Club Ltd which has been lodged at the High Court.
The case was filed on 18 February.
Lifelong fan Mr McGill is a former managing director and chairman of York City.
His company JM Packaging Limited bought 75% of the shares of York City Football Club Limited from fans group the York City Supporters’ Trust in 2006.
During his time in charge, Mr McGill was instrumental in negotiating the deal which saw the football club regain control of former ground Bootham Crescent, then selling it to Persimmon Homes for £7 million.
Some of the money Mr McGill had invested in the club was paid back as a result of that sale but all interest charges owed to JM Packaging were written off.

He then oversaw the club’s move to the new LNER Community Stadium, with the first game being played there in 2021.
Mr McGill sold his 75% stake back to the supporters’ trust and left the club the following year, shortly before Glen Henderson took over as majority shareholder and chairman.
YorkMix understands JM Packaging is now suing York City Football Club Limited over financial arrangements that date back to the arrangements drawn up at the time of this handover.
The alleged breach of contract is said to have persisted after York City was bought by new owners 394 Sports Ltd, co-owned by Matthew Uggla and Julie-Anne Uggla.
Mr McGill told YorkMix he couldn’t give full details yet of the writ, due to legal restrictions.
But he sent us this statement: “JM Packaging Ltd (JMP) confirms that its solicitors, Andrew Jackson of York, have commenced formal legal proceedings in the High Court for a substantial sum against York City Football Club Limited (the Club).
“The claim arises from JMP’s historical financial support of the Club.”
We have asked York City FC for a comment.
