Solicitor Tony McLynn, who acts on behalf of the anonymous winner, said the principal sum, plus interest, would be paid out.
“My client is happy with the outcome and will, in due course, at an appropriate and convenient time for all, collect the money,” said the Athlone-based solicitor.
“Everybody is happy now. The matter has been resolved,” he said.
The solicitor said his client was disappointed that Premier Lotteries Ireland, the licensed operator of the National Lottery, had commented on the matter.
Mr McLynn said comments made by PLI that the money had not been paid and that it was continuing to engage with the ticket-holder had fuelled speculation and rumour in the past number of weeks.
He said the privacy, security, and wellbeing of all winners should be of paramount concern.
The National Lottery said it always worked to ensure due process in its claims procedure and never commented on the specifics of individual claims.
Mr McLynn said that anything raised had been addressed and all parties were now happy to move on from the matter.
Meanwhile, a family in Doneraile, Co Cork, nearly missed out on a €500,000 Euromillions win. The winning ticket nearly ended up in the bin but the wife decided to do a double-check on the numbers.
Another lucky punter from Dublin won almost €30,000 on two Daily Millions bets placed on Friday.
Both winners want to remain anonymous.
