A lottery win has divided a family, but Facebook says the family should have divided the win.

More than 40 people tackled the ethical question on the Wagga family who has torn itself apart after winning $2.25 million on Valentine’s Day.

Sara McPherson said it was “unwritten law” that lottery winnings had to be shared with the winner, while Steven Cook argued “no amount of money is worth losing your family over”.

Alyssa Hay said the mother who bought the ticket for her son deserved a share in the win.

​“Everyone is different. But why wouldn’t you want to help out your mum?” she said.

Leearn Ray said it was the “sad reality” of greed.
