In California and most other places, therapists, psychologists, and counselors are bound by professional ethics and confidentiality rules. Disclosing information about a client's family without their consent can be a violation of confidentiality, which is taken very seriously in the mental health field.
Therapists are generally required to maintain strict confidentiality regarding all information shared by their clients during therapy sessions, including information about the client's family members. Exceptions to confidentiality typically involve situations where there is a risk of harm to the client or others.
If a therapist believes that sharing information about a client's family is necessary for treatment or for the client's well-being, they would typically seek the client's consent before doing so. In situations where there may be a need to disclose information without the client's consent (e.g., child abuse reporting requirements), therapists are generally mandated by law to make such disclosures.
Failure to maintain confidentiality without a valid reason could result in professional consequences, including potential loss of licensure. It's crucial for therapists to adhere to the specific ethical guidelines and legal requirements set forth by their respective professional boards and licensing bodies.
If you have specific concerns or questions about a therapist's obligations in California, it's best to consult with a legal professional or contact the relevant licensing board or professional association for the most up-to-date and accurate information.
