The Welsh side have been criticised by Vorm's former club, with the new Tottenham signing involved in complicated transfer proceedings this summer.
This summer's transfer business between Swansea City and Tottenham, and in particular, Michel Vorm's move to Spurs, could be taken to FIFA by the Dutchman's former club FC Utrecht, who say they are owed money from the deal.
The Netherlands goalkeeper, who will now compete with Hugo Lloris for the number one jersey at White Hart Lane, moved to the Liberty Stadium in 2011 for around £1.5 million.
As part of the transfer, Utrecht said a 30% sell on percentage was negotiated with the Swans if the player was to be sold on.
With Vorm having moved to Tottenham last month, Utrecht have said they are yet to see any of that money.
Spurs concluded a long drawn out deal that saw Vorm and Ben Davies move to London in exchange for former Swan Gylfi Sigurdsson and a cash amount said to be around £5 million. One angle Swansea could be arguing from, is that, in what would be a complicated affair, if Sigurdsson was swapped for Vorm, then the money Spurs sent to Swansea, as well as the possible credit involved in the deal because Sigurdsson was valued more than the Dutchman, was purely used to pay for Davies.
General manager of FC Utrecht, Wilco van Schaik, told BBC Sport that Swansea chairman Huw Jenkins informed the Eredivisie club that Vorm went to Spurs "for free", meaning any sell on fees were not applicable.
Van Schaik deemed such a decision "unbelievable and unacceptable."
Swansea responded to Van Schaik by issuing their own comments on the matter, firmly denying that they have behaved inappropriately.
"It was approved by the Premier League and also FIFA via their TMS system," said a club spokesperson.
"While we have been in contact with Utrecht as a matter of courtesy, we will continue to conduct our business in the best interest of our football club and our supporters and not based on the views of other clubs.
"Unlike some countries abroad, we do not have third party ownership of players in Britain.
"The club will not be commenting further on this matter."
