“In blench holdings, where the return for the lands is generally elusory, that return is for the most part due and payable si petatur tantum; and this clause, by universal practice, has been interpreted to mean, if asked only within the year (si petatur intra annum). If the duty is not demanded within the year, the vassal is not liable for it.” John Trayner, Trayner’s Latin Maxims 575 (4th ed. 1894).
