Carlos Tevez's representative Kia Joorabchian has hinted that the striker's proposed move to Manchester United may be settled out of court.
Tevez is keen to move to Old Trafford
Joorabchian's companies MSI and Just Sports Inc claim they own the economic rights to the 23-year-old.
Tevez's current side West Ham dispute this and Joorabchian's companies have issued the club with a High Court writ.
But Joorabchian told the Daily Star newspaper: "There is a possibility it may get resolved next week."
Tevez's transfer to the Premier League champions has stalled over who will be paid the £30m transfer fee - with Joorabchian's companies issued legal proceedings against the Hammers.
"I can confirm the companies have begun High Court proceedings against West Ham," said Teacher Stern Selby solicitor Graham Shear, representing the law firm representing MSI and Just Sports Inc.
Clearly, this is a dispute between Tevez, the owners and West Ham
The statement continued: "A High Court writ was served on the football club's solicitors.
"The Companies seek the court's intervention to compel West Ham to release the registration of Carlos Tevez in accordance with contracts entered into between the parties.
"We are asking the court to intervene so that Tevez can be registered to play with Manchester United as soon as possible.
"We will be making no further statement at this time."
West Ham said they would be consulting their lawyers over the writ.
Third-party ownership of football players is common in South America but was almost unheard of in England until Tevez and fellow Argentine Javier Mascherano joined West Ham in August 2006.
Mascherano has since moved to Liverpool.
Earlier, Fifa had recommended the Tevez dispute should go to the Court of Arbitration for Sport.
The Football Association and the Premier League had asked Fifa to rule on the matter.
But a Fifa statement read: "Fifa has recommended that West Ham and Carlos Tevez seek arbitration at CAS.
"Under the present circumstances this was deemed to be the best approach and in the interest of all parties.
"What is more, we also believe this to be the fastest way to solve this impasse."
Manchester United chief executive David Gill says his club just wants the situation to be resolved as quickly as possible.
"Clearly, this is a dispute between Tevez, the owners and West Ham," stated Gill.
"Hopefully, that can be solved relatively quickly and he can come to join us. I would have thought they have taken this decision in the belief that he can join us."
Tevez is registered as a West Ham player but Joorabchian claims he still owns the striker's economic rights and is therefore entitled to the transfer fee.
However, West Ham ripped up an agreement they had with Joorabchian - which broke Premier League rules - and they now claim any deal with United can only go ahead with their say-so.
The Premier League, which is also insisting that any fee must go to West Ham, met Fifa and the Football Association on Monday to discuss the issue.
The Premier League welcomed Fifa's decision.
"We are supportive of the recommendation that if all parties are in agreement the matter should be referred to the Court of Arbitration for Sport," said a Premier League spokesman.
West Ham also said they were happy for CAS to rule on the issue.
"We're happy for the matter to go to CAS if it is with the agreement of all parties," a West Ham statement said.
West Ham were fined £5.5m pounds in April for breaking Premier League rules over third-party ownership when they signed Tevez.
They were allowed to continue playing him after satisfying the Premier League that the third-party agreement with Joorabchian had been torn up.
