The former nanny to the Cranberries singer Dolores O'Riordan and her Canadian husband Don Burton is suing the celebrity couple claiming breach of contract and false imprisonment.
Joy Fahy of Moyleggan, Batterstown, Co Meath, worked for the couple in 1999.
She claims Mr Burton reneged on a lucrative agreement, which was never placed in a written contract. She also claims Mr Burton became abusive and aggressive towards her.
Ms O'Riordan and Mr Burton are defending the action and disputing the terms of the contract. They claim Ms Fahy walked out.
