Conditions Requiring Future Events to Have Legal Effect

Notes

1. §12.1.39.prtunc ... cum — The correlation between the adverb tunc and the conjunction cum does not merely denote simple simultaneity, but here carries a restrictive or conditional force ('only when...', 'only if...'). This fits the legal context where past or present facts do not constitute a 'condition' in the strict sense, and thus the force of a condition arises only when directed to the future.
2. §12.1.39.proptinet — The verb optineo (obtineo) means 'to hold', 'maintain', or 'obtain'. The subject of this third-person singular active verb is not explicitly expressed, but from the context of the preceding text, it is understood to be an implicit subject such as the agreement (stipulatio or pactum) containing the provision.
