What is Admeasurement Of Dower?

Legal Definition
Remedies. This remedy is now nearly obsolete, even in England; the following account of it is given by Chief Baron Gilbert. "The writ of admeasurement of dower lieth where the heir when he is within age, and endoweth the wife of more than she ought to have dower of; or if the guardian in chivalry, [for the guardian in socage cannot assign dower,] endoweth the wife of more than one-third part of the land of which she ought to have dower, then the heir, at full age, may sue out this writ against the wife, and thereby shall be admeasured, and the surplusage she hath in dower shall be restored to the heir; but in such case there shall not be assigned anew any lands to hold to dower, but to take from her so much of the lands as surpasseth the third part whereof she ought to be endowed; and he need not set forth of whose assignments she holds." Gilb. on Uses, 379; and see F. N. B. 148; Bac. Ab. Dower, K; F. N. B. 148; Co. Litt. 39 a; 2 Inst. 367 Dower; Estate in Dower.

Comm. 136; Gilb. Uses, 379. In some of the states the statutory proceeding enabling a widow to compel the assignment of dower is called "admeasurement of dower."
