Joint or shared holding or ownership of property, office, or position by two or more people.
From co- plus tenure (from Latin 'tenere' meaning to hold, plus '-ure' suffix indicating a state or condition). This formal term describes simultaneous shared control.
Cotenure appears in historical records when two lords shared control of a castle or land—it was an ancient way of preventing one person from having absolute power, like today's co-CEOs but with swords.
