Principle

No. I.3.1 - Limitation of transfer of rights

No one may transfer more rights than he actually has ("nemo plus iuris transferre potest quam ipse habet").

Commentary
It follows from this Principle that only the person who holds a legal title to a right (e.g. property, creditor of a contractual claim) may transfer that right or modify it.
