International border disputes

Since 1980 Menas has provided specialist research and expert testimony services in international territorial disputes.

We support governments and law firms by gathering vital evidence to prove the ownership of onshore or offshore territory in border dispute cases heard before the International Court of Justice in The Hague and in bilateral arbitration courts. We also help governments to determine the strengths and weaknesses of their claims before they are submitted to any court.

Working in close partnership with specialist lawyers, our role typically involves paralegal activities such as archival and historical research of primary and secondary sources of information; cartography and map research; technical surveying, hydrography, and remote sensing; anthropology, geography and primary field work.

We have also conducted major studies for international oil companies of the competing claims in the North and South Atlantic, Mediterranean, Red Sea, Black Sea, Caspian Sea, Persian Gulf, Indian Ocean, Gulf of Thailand and the South China Sea.
