Русско-англо-русский юридический словарь

Under appropriate points in his brief appellant says the court erred in decreeing that appellee was entitled to possession of the land pursuant to the deed from the Levee District to appellee dated January 29, 1929, because the grant in such instrument was made on a condition precedent which was never performed or, in the alternative, on a condition subsequent which was breached, thereby giving appellant, as assignee of appellee's grantor, the right of reentry. (Etheridge v. City of Dallas, Casetext)

A transaction shall be made on a condition subsequent, if the parties have placed the termination of rights and duties in dependence upon a circumstance with respect to which it is unknown whether it will occur or not occur. (The Civil Code of the Russian Federation, translation by Peter B Maggs)
