[TRYPHONINUS libro septimo decimo disputationum. ] §37.15.10.prNullum ius libertatis causa impositorum habet in mancipato filio, quia nihil imponi liberis solet.
[TRYPHONINUS, from the seventeenth book of Disputations.] A father has no right over a son who has been sold into bondage and then freed regarding things imposed by reason of manumission, because nothing is customarily imposed on children.
nec quisquam dixit iureiurando obligari filium patri manumissori ut libertum patrono: nam pietatem liberi parentibus, non operas debent.
Nor has anyone ever said that a son is bound by an oath to his manumitting father in the same way as a freedman is to his patron; for children owe affection to their parents, not services.
