Succession duty, in the English fiscal system, "a tax placed on the gratuitous acquisition of property which passes on the death of any person, by means of a transfer from one person (called the predecessor) to another person (called the successor)." In order properly to understand the present state of the English law it is necessary to describe shortly the state of affairs prior to the Finance Act 1894--an act which effected a considerable change in the duties payable and in the mode of assessment of those duties.
