Nec vi, nec clam, nec precario

Legal term relating to permissions over land

Nec vi, nec clam, nec precario, is a Latin legal term meaning 'without force, without secrecy, without permission' or, in an alternative formulation offered, for instance, by Lord Hoffmann, 'not by force, nor stealth, nor the licence of the owner'. It is the principle by which rights may be built up over time, principally public rights of way in the United Kingdom. Specifically, if a path is used – openly, not against protests, but without permission of the landowner – for an extended period then a permanent legal right to such use is usually established.
