Mother Hubbard

Mother Hubbard can have different, probably related, meanings:

A Mother Hubbard Clause is a provision in a deed for the conveyance of real property that attempts to sweep within it other parcels not specifically described.

For example: O gives B a mortgage on a tract of land and "all other land I own in Delaware." O owns several other tracts of land in Delaware. Generally, Mother Hubbard clauses are not valid against subsequent purchasers of the undescribed land, and a bona fide purchaser of the other land in Delaware would not take subject to the mortgage.
