Definition
A writ of English law available to a widow when it had been judicially established — by office (an inquisition held to determine the king's rights and interests) — that her deceased husband had held lands in fee simple or fee tail at the time of his death and that he had held those lands directly of the king in chief. The widow who sought the writ was required to appear in chancery and swear an oath that she would not remarry without the king's leave. Upon taking that oath, the writ issued to compel assignment of her dower. Widows who proceeded under this writ were known as "king's widows."
The writ belongs to the family of dower writs and is distinguished from ordinary dower process by the presence of the king as the husband's immediate overlord, which imposed an additional procedural burden — the oath of chastity and loyalty — before the widow could access her remedy.
Common Confusion
DOTE ASSIGNANDA should not be confused with DOTE UNDE NIHIL HABET, a separate and more general writ of dower that lay for a widow against a tenant of lands of which her husband had been solely seised in fee simple or fee tail, with no requirement that the husband had held of the king in chief. Dote unde nihil habet was the standard common-law dower writ; dote assignanda was the specialized variant triggered by the feudal tenure relationship with the Crown. Rapalje & Lawrence treats both writs in immediate succession, which occasionally leads researchers to conflate them when reading older digests and abridgments.
Why It Matters in Research
This term belongs entirely to pre-modern English feudal procedure and will not appear in American law in operative form. Researchers encounter it almost exclusively in one of three contexts: (1) reading English legal history sources dealing with dower rights and feudal tenure; (2) working through early English abridgments, form books, or register of writs (Registrum Brevium) that catalogue the writs of the common law; or (3) tracing the intellectual genealogy of American dower doctrine in historical treatises that begin with English foundations.
The practical significance of the writ was tied directly to the feudal incidents of tenure in chief — specifically, the Crown's right to consent to the remarriage of a tenant's widow. That right disappeared with the statutory abolition of feudal tenures in England (Tenures Abolition Act 1660), which rendered this writ obsolete. American law never adopted the concept of tenure in chief at all, so dote assignanda has no American analogue.
When researching colonial or early American dower law, be alert to sources that invoke the English writ vocabulary without signaling that the underlying feudal structure had already been stripped away. An early American treatise citing Fitzherbert's Natura Brevium (the standard authority referenced in the historical dictionaries as "F. N. B. 26") may be importing English writ terminology into a context where the writ itself could not function.
The requirement that the widow swear not to remarry without royal permission is historically significant for research into the intersection of dower, guardianship in chivalry, and the feudal control of widows — topics addressed in medieval English legal history but largely invisible in American legal sources.
Historical Dictionary Support
The four source dictionaries are in close agreement on the essential elements: a finding by office, tenure in fee or fee tail, holding of the king in chief, and the oath in chancery. Black's Law Dictionary (both editions) and Bouvier's are nearly identical in language. Rapalje & Lawrence adds the citation to Fitzherbert's Natura Brevium (F. N. B. 26) and the Registrum Originale (Reg. Orig. 297), which are the primary historical authorities and the appropriate starting points for any researcher seeking the original writ form.
None of the historical dictionaries address the abolition of the writ or its inapplicability to American law — a gap worth noting. They define the writ as it existed in the English common law without flagging its obsolescence. Bouvier in particular presents it descriptively as if it were part of a live system, consistent with his general method but potentially misleading to researchers who do not already know the feudal context.
The phrase "king's widows" (viduae regis) referenced in the dictionaries is a recognized term of art in English feudal law designating women whose remarriage was under royal control as an incident of their husbands' tenure. This places dote assignanda within a broader web of feudal widow-management that researchers studying medieval property or family law will recognize from other sources.
