Welsh Coop Centre

Offers free advisory service for legal structure and setting up co-ops or community land trusts. Managed by Dave Palmer. If an OPD has multiple dwellings he feels it should be managed by a trust or co-op. Additional businesses might have their own legal structure. Initial questions with regard to the choice of an appropriate legal form for an OPD are:

  1. Are they leaseholders, or tenants?
  2. How is the land to be owned if they are leaseholders?
  3. A Co-operative Society cannot have a statutory asset lock (although it can have a members’ asset lock i.e. common ownership dissolution clause).
  4. A Community Interest Company (CIC) or a Community Benefit Society (CBS) can, as can a Community Land Trust (CLT).  A CBS would have to show benefit to the community as well as to members.
  5. Would there be other stakeholders involved in governance?

They are happy to visit OPD sites/groups. See Also read this one-pager on Co-op housing (PDF) and download an Enquiry-Form (Word doc).
