Mickey Rooney's kids are contesting the late movie veteran's will, insisting he faced "undue influence" when he signed it weeks before his death. Seven of Rooney's biological children have filed suit in Los Angeles seeking that their father's will be invalidated. They lost out when the actor's documents were made public after his death last month (Apr14) - he named his stepson and caretaker Mark Aber as the beneficiary to his estate, which is valued at $18,000 (GBP11,250). Rooney's kids claim Aber and the estate's current executor, attorney Michael Augustine, took "advantage" of their father. In the legal papers they have filed, the siblings claim Aber and Augustine "suggested and dictated the contents of the (will)" and "arranged for the execution of the document" at a time when Rooney was "wholly under the influence" of the two men. Augustine's lawyer Richard Petty tells People.com, "We think the contest is utterly without merit and that there is no truth at all to any of the allegations."
