loco tutoris (loh-koh t[y]oo-tor-is). [Latin] Scots law. In the place of a tutor.

“The Court of Session is in the practice of appointing, on application made for such appointment, a factor loco tutoris on the estates of pupils not having tutors. Such an appointment places the factor in the same position towards the pupil, both as regards his person and the administration of his estate, as if he held the office by virtue of relationship and was tutor-at-law, or had received the appointment of tutor from the pupil’s father under his testamentary settlement, the only difference being that the office of a tutor appointed by the Court is not gratuitous.” John Trayner, Trayner’s Latin Maxims 336–37 (4th ed. 1894).
