Association of Scottish Community Councils
To be on a community council, you generally need to be on the electoral roll for that council's area. Because the electoral roll is compiled in November, but the elections to the community council are in September, this means you must have been living in the community council's area for between 10 and 22 months in order to be eligible to stand.
