In the Roman law, from which they are taken, the expressions”in rem” and “in personam” were always opposed to one another, an act or proceeding in personam being one done or directed against or with reference to a specific person, while an act or proceeding in rem was one done or directed with reference to no specific person, and consequently against or with reference to all whom it might concern, or “all the world.” The phrases were especially applied to actions; an actio in personam being the remedy where a claim against a specific person arose out of an obligation, whether ex contractu or ex malcficio. while an actio in rem was one brought for the assertion of a right of property, easement, status, etc., against one who denied or infringed it. See Inst. 4, 6, 1; Gains, 4, 1, 1-10; 5 Sav. Syst. 13, et seq.; Dig. 2, 4, 7,8; Id. 4. 2, 9, 1.From this use of the terms, they have come to be applied to signify the antithesis of”available against a particular person,” and “available against the world at large.” Thus,jura in personam are rights primarily available against specific persons; jura in rem.rights only available against the world at large.So a judgment or decree is said to be in rem when it binds third persons. Such Is The sentence of a court of admiralty on a question of prize, or a decree of nullity or dissolution of marriage, or a decree of a court in a foreign country as to the status of a person domiciled there.Lastly, the terms are sometimes used to signify that a judicial proceeding operates on a thing or a person. Thus, it is said of the court of chancery that it acts in personam-, and not in rem, meaning that its decrees operate by compelling defendants to do what they are ordered to do, and not by producing the effect directly.

Eq. 150, 57 Atl. 555.In personam actio est, qua cum eo agimus qui obligatus est nobis ad faciendumaliquid vel dandnm. The actioi in personam Is that by which we sue him who is underobligation to us to do something or give something. Dig. 44, 7, 25; Bract 1016.
