Facebook co-founder Mark Zuckerberg has launched a raft of lawsuits that could see the U.S. billionaire secure full ownership of his island hideaway from local Hawaiian families who retain rights over the land dating back generations.

Documents filed on Dec. 30 in the Hawaii State circuit court — and reported in the Honolulu Star Advertiser newspaper — show that three Zuckerberg companies filed the lawsuits under what is known as "quiet title and partition."

This is the legislative process used to establish ownership of land where inheritance has occurred over generations and there is no formal documentation or title deeds.
