What options are available to assess the Risk Profiles for a Joint Client?

Whilst it would be possible to ask Joint Clients to sit together and complete the Risk Profiler Questionnaire, this would potentially go against expert advice that suggests the client completes a psychometric questionnaire without spending too much time considering or debating the answers. Another option would be to ask each Client to complete a Risk Questionnaire separately about their joint investments and then for the Adviser to discuss the different outcomes and liaise with both individuals to agree on the appropriate risk profile for both Clients about their joint investments.
