After spending more than two decades in jail, Kathleen Folbigg has been cleared of causing the deaths of her four children.

"I hoped and prayed that one day I would be able to stand here with my name cleared," she said outside the NSW Court of Criminal Appeal, where applause broke out minutes earlier as her convictions were quashed on Thursday.
