Del. Code tit. 22 § 825
A municipal legislative body or charter commission which proposes the termination of home rule charter status by repeal of a home rule charter shall incorporate in the proposition to be submitted to the qualified voters a specification of the form of government under which the municipal corporation would thereafter operate in the event of repeal, whether it be a form prescribed by general law for municipalities of its population class or 1 of such optional forms as may have been authorized by general law for municipalities of its population class. A municipal legislative body or charter commission proposing charter repeal shall also, by resolution of that body, determine when the transition to the new form of government would take place in the event of repeal and make such other provision, as may be appropriate, to effect an orderly transition from home rule charter to nonhome rule charter status.
