Neymar is free to make his Paris Saint-Germain debut at Guingamp on Sunday after Barcelona confirmed on Friday the 222 million-euro ($261 million) cheque used to pay his buyout clause had cleared.
"The cheque has cleared and therefore puts in motion the process of the transfer," said a Barcelona club source.
The French Football Federation (FFF) and French league (LFP) confirmed to AFP on Friday that the player's transfer certificate had been received from the Spanish Football Federation (RFEF).
That will allow him to be registered for the game at the Stade du Roudourou.
"Neymar's contract will be ratified during the afternoon. He will be able to play on Sunday," said the LFP.
Neymar's move to the French giants that smashed the world record transfer fee was announced on August 3.
However, he had to watch last weekend's 2-0 win over Amiens from the stands as the administrative formalities of the deal were not completed in time.
FFF president Noel Le Graet had earlier stated his confidence that Neymar would be able to make his bow in Brittany.
"There is no reason for this hold-up to continue," he told French sports daily L'Equipe.
"I do not doubt that this will be quickly solved.
