As a life coach you have a moral duty and responsiblity to maintain the strictest confidentiality with you clients. Clients should always feel comfortable enough to confide in you.
At the beginning of every client relationship a side note about confidentilaiy should be established and then again in your clinet agreement.
The statement and agreement should make the client aware that you will maintain the strictest level of confidentiality unless they seem as though they will hurt themselves or someone else. They should be aware that you will notify any law enformcement agencis or refer them to seek appropriate medical care if the situation occurs.
