Utrecht insist they are owed 30 per cent of whatever Swansea received for Vorm in July 2014, citing a sell-on clause in the deal when the goalkeeper arrived in Wales from the Netherlands three years earlier.
Vorm left Swansea on the same day as defender Ben Davies, with forward Gylfi Sigurdsson going the other way, and Utrecht have questioned why Vorm, a Holland international with two years on his contract at the time, was given a zero value in the transactions.
The Dutch club confirmed on Thursday they will take the case to CAS in Switzerland but Swansea, who had a FIFA ruling over the issue in their favour earlier this year, say they have done nothing wrong over the Vorm transfer.
"From our side everything is fine and I'm sure the club has followed everything to the letter," Swansea manager Monk said at his pre-match press conference ahead of the Barclays Premier League visit of Everton on Saturday.
"But t hose issues will be left to the club and not the footballing side with myself
"I'm not worried
We're a perfectly run club and the decision earlier in the season from FIFA showed it was all okay
"I think that proves everything, and if they (Utrecht) want to pursue it that will be left to the chairman and the board and the administration side to deal with it
"It's not really a focus for me, it's up to the club and the chairman to deal with."
Utrecht general manager Wilco van Schaik said in August 2014 that Swansea chairman Huw Jenkins had told him Vorm had gone to Tottenham "for free".
Schaik told BBC Wales: "That's unbelievable and unacceptable
Michel is a very reliable goalkeeper in the Premier League.
"He is 30-years-old, in the prime of his life
He still had a two-year contract and has a good reputation.
"Besides that, he's a solid member of the Dutch squad
We want to have the 30 per cent as we agreed."
Swansea welcome Everton and their former manager Roberto Martinez on the back of their first defeat of the season at Watford last weekend.
Monk accepts Swansea fell below the standards they had set in the opening weeks of the season when they beat Manchester United and drew at Chelsea during a four-game unbeaten start.
"We never reached the levels we should have done to perform how we want," Monk said.
"We spoke about that when we came back in this week and I think it was a little bit of loss of focus of what we're good at and the game plan we try to follow.
"We just didn't execute it and there's no excuses from our end.
"We're aware of that and the players have responded well this week and hopefully we'll get a reaction in the next game.
"We've been good at home this season and we want to continue that."
