The star was recently sued by officials at Neil Brooks Management, who helped a young Murray land his role as Irish student Seamus Finnigan in the first two boy wizard movies, 2001's "Harry Potter and the Philosopher's Stone" and 2002's "Harry Potter and the Chamber of Secrets", reported New York Daily News.
In the lawsuit, owner Neil Brooks claimed relations with the actor and his family broke down after they allegedly failed to pay commission, as agreed in a 1998 contract, and the Murrays then tried to ditch the talent agent after completing two more installments of the Potter series.
However, Murray and his parents Michael and Fidelma, challenged the accusations, insisting they handed over more than USD 111,320.
Justice Michael Moriarty sided with Brooks, ruling the actor should pay up the USD 300,000. The judge also dismissed a USD 1,11,500 counterclaim filed by Murray and his family. He was also ordered to cover legal fees.
Addressing the ruling and reports he squandered his earnings on women, cars and partying, Murray said, "What's done is done now. There's nothing we can do. We're all gutted (disappointed) now. There's not a whole lot we can do. We have to get by whatever way we can now.
