How did the Magna Carta regulate inheritance payments called reliefs?

Prior to the signing of the Magna Carta in 1215, King John had frequently abused his power by levying massive, arbitrary reliefs—the inheritance duties paid by an heir to an overlord upon succeeding to a fief. For instance, some barons were charged thousands of marks, far exceeding traditional customs.1

To curb this oppressive practice and ensure the king remained subject to the law, the Magna Carta established fixed, reasonable limits on these payments. Specifically, the document standardized the relief for a barony (a large landed fief) at £100. By setting these clear, predictable rates, the charter sought to provide guarantees against the arbitrary disregard of feudal rights that had characterized the rule of the Angevin kings.1
