Premier League chief executive Richard Scudamore is confident that the league now has regulations in place to make sure there is no repeat of the Carlos Tevez affair.
Scudamore believes the clubs now understand they must submit all documentation relating to a transfer before they can be approved.
He believes lessons have been learned as the Tevez case comes to an end with his pending transfer to Manchester United from West Ham, who were fined £5.5m last season for third party irregularities over his move to Upton Park last summer.
Scudamore insisted: "We have changed the rules this summer, clubs are in no doubt now. West Ham initially claimed that there was no need to submit these forms or indeed that what they were doing broke our rules.
"Now we have changed the rules to say that clubs must send any documentation relating to the deal, whether you believe it is relevant or not.
"It must be sent in, we will have a look and let the people who guard the rules be the judge as to whether things do need to be seen or not."
He added: "At the same time we have made it clear that within a players' contract registration section it will be taken into account rules U18 and U6, the offending rules in the West Ham case, so there is no doubt now that clubs have to send the documents in and that the board will be looking at them in light of these two rules.
"Every transfer, every registration, is different with clauses and documents that we need to verify and vet. All we are saying that a transfer arises tomorrow we will run the rules past it, it doesn't matter who it is from, and we will check that against our rules.
"If it is in accordance with our rules they will be registered, if they are not, then they won't be registered."
Scudamore know the league dare not have a repeat of the Tevez row, one of the most damaging transfers in the league's history.
He said: "Last August we in good faith believed what people at West Ham were telling us and the biggest lesson is that we will probably be a more circumspect in the future about that sort of communication with clubs.
"It is a matter of record that West Ham admitted bad faith, they admitted not being absolutely clean and open with us in terms of their dealings with the situation.
"This is an association of clubs and we have a rule book we all agree to abide by and if you have bad faith then the show can come off the road and that is what happened.
"It all got derailed because of that, so that is the biggest lesson for us as far as I am concerned."
Third party involvement is not against league rules, but the clause in Tevez and Javier Mascherano's contracts allowing outside control over transfers, is.
Underlining the point, he added: "We have sanctioned a deal with third parties, and that is the move of Javier Mascherano to Liverpool.
"That was done properly, Liverpool came in through the front door and they showed us all the documentation up front and we worked with Liverpool as we do with all clubs, to make sure these things comply and sat within the rules."
The final details of Tevez's move to Old Trafford will be completed this week and he will make his debut for the club in a friendly on Wednesday.
