/ˈæk.tər ɪn ˈrɛm ˈsu.æm/ – Phrase
Definition: người (kể cả nguyên đơn) hành động nhân danh cá nhân mình, một cách độc lập, không thông qua người khác (kể cả luật sư).
A more throughout explanation: “In rem suam” is a Latin term that translates to “in his own thing” in English. In legal terms, an actor in rem suam refers to a person who acts in their own interest or on their own behalf, as opposed to representing someone else or acting on behalf of another party.
Example: The actor in rem suam claimed ownership of the property based on his legal title deed.
