In Civil law, real right refers to a right that is attached to a thing rather than a person. Real rights include ownership, use, pledge, usufruct, mortgage, habitation and predial servitude. (USLegal)

A servitude is a qualified beneficial interest severed or fragmented from the ownership of an inferior property (servient estate) and attached to a superior property (dominant estate) or to some person (personal beneficiary) other than the owner.[1] At civil law, ownership (dominium) is the only full real right whereas a servitude is a subordinate real right on par with wayleaves, real burdens (i.e. real covenants), security interests, and reservations.

Acquisitive prescription. Definition - : acquisition of ownership or other real rights in movables or immovables by continuous, uninterrupted, peaceable, public, and unequivocal possession for a period of time (as 10 years) set by law. (Lawyers.com)

Under the civil law system, cession is the equivalent of assignment, and therefore, is an act by which a personal claim is transferred from the assignor (the cedent) to the assignee (the cessionary). Whereas real rights are transferred by delivery, personal rights are transferred by cession. Once the obligation of the debtor is transferred, the cessionary is entirely substituted. The original creditor (cedent) loses his right to claim and the new creditor (cessionary) gains that right. (Wikipedia)
