The Breakfast at Tiffany's star bequeathed a treasure trove of items from her long-running Hollywood career, including jewellery, hats, scarves, scripts and trophies, to her children, Sean Ferrer, from her marriage to Mel Ferrer, and his half-brother Luca Dotti, from her marriage to Italian psychiatrist Andrea Dotti.

The actress decided her sons should take half the collection each, but they have reportedly become embroiled in a dispute over which items they want to claim and are now taking their disagreement to court.

Editors at TMZ.com report a judge is now set to make the final decision on the collection, which is currently housed at a storage facility in Los Angeles.

Hepburn died in 1993 at the age of 63.
