It was in January, 2011 when the Triss lotto card was purchased, however neither the mother, 59, nor daughter, 35, could even agree who bought it.
The pair, who both lived in Blekinge, southern Sweden, won the opportunity to either claim a 500,000 kronor prize or appear in a live television broadcast with a chance to win a higher amount.
The camera-shy mother allegedly asked her daughter to take her place.
When the second stage of the lottery was televised, the family won three million kronor to be paid in monthly installments of 10,000 kronor for 25 years.
However, after the first payment came through in April last year, the rift began. Now the mother and daughter live apart, and are no longer on speaking terms.
The daughter alleges that as it was her on television and her name on the ticket, the money should be hers, whereas the mother argues that she bought the ticket and asked her daughter to appear in her place on the show.
The matter was taken to the district court in Blekinge on Monday to be settled, and prosecutors pushed for reconciliation of the pair.
In the early afternoon, the mother and daughter agreed to reconcile, and their lawyers been given two weeks to negotiate how the money will be divided.
“It's nice to know this sad story is over,” said the daughter to the Aftonbladet newspaper.
