Cal. EDC § 21117

Any person making the grant may, at any time thereafter, by last will or testament, devise and bequeath to the state all or any of the property, real and personal, mentioned in the grant, or in any supplemental grant, and the devise or bequest shall only take effect if, from any cause whatever, the grant is annulled or set aside, or the trusts therein declared for any reason fail. Such devise and bequest is permitted to be made by way of assurance that the wishes of the grantor shall be carried out, and in the faith that the state, if it succeeds to the property, or any part thereof, will, to the extent and value of the property, carry out, in respect to the objects and purposes of the grant, all the wishes and intentions of the grantor.
