Duorum in solidum dominium vel possessio esse non potest
Duorum in solidum dominium vel possessio esse non potest is Latin legal term meaning "Sole ownership or possession cannot be in two persons" / "Two persons cannot own or possess a thing in the entirety."[1]
It is a variation of a more popular Latin legal phrase, which is attested to in Coke's Institutes: Duo non possunt in solido unam rem possidere: "Ownership of a whole cannot be shared; right of ownership must be divided into portions."[2]
