OWNERSHIP GROUP DOCUMENTATION
The Racing Manager strongly recommends that a formal written agreement is put in place between the Group Manager, on behalf of the Ownership Group, the trainer of the horse(s) owned or leased as applicable, and the Group Members setting out the relationship between the parties and detailing in particular the responsibilities of each party and the financial aspects of the arrangement.
All Group Managers, in relation to the Ownership Group, should ensure that they are aware of the requirement of the British Horseracing Authority Rules of Racing and related guide the Rules of Racing of Great Britain: http://rules.britishhorseracing.com.
The British Horseracing Authority also publish a Syndicate Code of Conduct https://www.britishhorseracing.com/wp-content/uploads/2014/03/Syndicate-Code-of-Conduct.pdf that is applicable to Ownership Groups as detailed in the code.
The Racehorse Owners Association website is also a source of useful information including several agreement templates. https://www.roa.co.uk/en/utilities/search-results.cfm?keyword=templates
