But Cleopatra star Taylor claims the family has failed to show that the artwork was ever illegally seized from Mauthner.
I would think that it would work the other way - that she would have to prove clear title to the work.
Elizabeth Taylor has clear title--a bill of sale from a reputable company which has given its provenance.
Therefore the plaintiffs have to show some evidence that the provenance was incorrect. If they can show that the work was wrongfully taken, then it would become a matter for the court to decide proper ownership.
