The Taxi Driver star, who is the executor of his father's estate, filed suit against Salander-O'Reilly Galleries owner Lawrence Salander in 2007, alleging he sold some of De Niro Sr.'s works to settle the company's debts.
De Niro has now made a deal with the trustee overseeing the bankrupt firm - he's handed over a £8,750 cheque in exchange for six works of art by his father, who was an abstract expressionist painter and sculptor. The deal stops the pieces from going to auction along with other works once housed at the gallery.
The artwork represents half the number of the pieces gallery founder Salander has been charged with stealing from De Niro Sr.
The lot of 12 works was valued at more than £625,000, reports the New York Post.
Salander declared bankruptcy in 2007 and is awaiting trial on charges of cheating clients out of £55 million.
