Crown Private Estate Act 1800

8 Her Majesty during the joint lives of their Majesties, by deed, or by will, may dispose of manors, etc. purchased by or in trust for, or that may vest in her Majesty, or in trust for her, and may bequeath all such chattels and personal estate as if she were sole; E+W+S

And whereas by the law of England the Queen Consort, wife of the King, is capable of taking, granting or disposing of property as if she were a feme sole, but doubts may arise how far this capacity of granting or disposing of property extends, and especially whether during the life of the King her husband it includes the power of devising and bequeathing by last will and testament: And whereas his Majesty is desirous that her Majesty Queen Charlotte, his Majesty’s royal consort, during his Majesty’s life should have full and complete power, as well by her last will and testament as by deed, to grant, alien and dispose of any manors, messuages, lands, tenements, rents, tythes and hereditaments, which have been purchased by or in trust for or otherwise vested in her Majesty, or which shall hereafter be purchased by or in trust for or shall be otherwise vested in or in trust for her Majesty, under and by virtue of any deed, gift, will or otherwise, except as herein-after is mentioned, and of any goods and chattels, whether real or personal, and personal estate of what kind soever belonging to her Majesty, in the same manner as her Majesty might dispose thereof if she were sole and unmarried, and it may be convenient that the like power should be secured to every Queen consort of this realm for the time being: Now therefore be it further enacted, that it shall be lawful for her Majesty at any time or times during the joint lives of their Majesties, by deed under her hand and seal, to be executed in the presence of and attested by two or more witnesses, or by her last will and testament in writing, or any writing in the nature of a last will and testament, to be signed and published by her in the presence of and attested by three or more witnesses, to grant, give, alien, dispose of, convey or devise any manors, messuages, lands, tenements and hereditaments, which have at any time heretofore been purchased or which shall at any time hereafter be purchased by or in trust for her Majesty, or which shall hereafter come to or devolve upon or vest in her Majesty or any person or persons in trust for her, for any estate of inheritance or freehold or for any copyhold or customary estate, under or by virtue of any deed, gift, will or otherwise, for all or any part of such estate, right and interest as her Majesty or such person or persons in trust for her now hath or have or shall or may have in any such manors, messuages, lands, tenements and hereditaments, and also by her last will and testament in writing to give and bequeath all such chattels and personal estate whatsoever as aforesaid, unto any person or persons and for any intents and purposes and in any manner she shall think fit, as fully and effectually in all respects as she could or might grant, convey, alien, dispose of, give, devise or bequeath the same, if she were sole and unmarried.
