is the name given to the
party who asserts or vindicates in an action (liberale
) the freedom of another (Gaius, 4.14); for a person
who claimed to be free could not sue on his own behalf. By the law of the
Twelve Tables it was enacted in favour of liberty, that an adsertor should
not be called on to give security in the sacramenti
to more than the amount of 50 asses. In the course of the
action the adsertor laid his hand on the person whose liberty he claimed
), and formally asserted the right
of the latter to his freedom. Hence adserere in
libertatem, liberali adserere manu.

collusive action for the purpose of manumitting slaves (manumissio per vindictam
). In later times the part of
assertor was represented by the Praetor's lictor. (Dig.
