A common seal is the official stamp or ‘signature’ of an association.  As a body corporate an association is entitled to have a common seal though it is not compulsory. Common seals are not expensive to purchase and can be obtained from most stationery shops or rubber stamp suppliers.

If an association has a common seal the rules must outline who is authorised to use it, the circumstances in which it may be affixed and who will have custody of the seal.
