When a new U3A starts up, it has to present its Constitution at the first AGM.
Guidance is given by National U3A who offer a model Constitution to work from. Some of the clauses in it are mandatory, but many can be tailored by each new U3A to local circumstances.
A few of these will be :What the new U3a is to be called; what territory will be covered eg immediate area around town or village; method of selecting committee; when and where they are to be elected ; how long members of the Committee will serve and many more.
All of this was decided by our Bedford U3A Founders and revised in 2018
