The adoption of the bill formally opens the way for Montenegrin President Filip Vujanovic to call for a referendum on 21 May, as agreed by the parliamentary parties.
Tomorrow, Vujanovic will officially propose that the parliament call the referendum on Montenegrin independence.
Montenegro is the only state of former communist Yugoslavia that remains allied with Serbia following the six-republic federation's break-up in a series of wars during the 1990s.
