Ball's daughter with first husband Desi Arnaz, Lucie Arnaz Luckinbill, was left items including love letters, a Rolls Royce and trophies from the star's acting career in her mum's will when the comedienne died in 1989.
However, the widow of Ball's second husband, Susie Morton, claimed Luckinbill failed to collect the items following Ball's passing, and planned to sell them off at Heritage Auction Galleries over the weekend (17-18Jul10).
Luckinbill threatened to take legal action over the auction of her late mother's personal items because it "insults her memory".
Auction bosses stepped in, and agreed on Saturday (17Jul10) to return the awards to Luckinbill, but the other items remained in the sale.
Luckinbill plans to display the trophies in a museum honouring her mother, reports the Associated Press.
