When a township or a fraction of a township has been attached to another township, the several boards of township supervisors and the clerks of the townships affected by the change shall meet prior to the annual township meeting at the usual meeting place of the township to which the annexation has been made or at a location mutually agreed upon in the township to which the annexation has been made or in an adjacent township, and upon notice of such meeting given by the clerk thereof, for the purpose of determining the amount due to the township to which the annexation has been made. All questions arising at such meeting must be determined by a majority vote of the members of the boards of township supervisors and the clerks present at such meeting.
