The Earldom has been dormant since the death of the 10th Earl in 1995, but the petition of the probable Hungarian heir, Huba Campbell (born 1945) is before The Lord Lyon . A four times removed cousin from the 10th earl.
Currently, the earldom is under a dispute between the Hungarian Campbells and a British aristocrat, Sir Lachlan Campbell, a direct descendant of the first earl. The last is apparently unable to succeed because it is said that his line is illegitimate.
