[GAIUS libro quarto ad legem Iuliam et Papiam. ] §22.5.5.prIn legibus, quibus excipitur, ne gener aut socer inuitus testimonium dicere cogeretur, generi appellatione sponsum quoque filiae contineri placet: item soceri sponsae patrem.
[GAIUS, On the Lex Julia et Papia, Book 4.]In the laws in which an exception is made that a son-in-law or a father-in-law should not be compelled to give testimony against his will, it is accepted that the term "son-in-law" also includes the daughter's fiancé; likewise, [that the term "father-in-law" includes] the fiancé's father.
