Legal Question in Family Law in California

If the child was taken from his mother, there must be a dependency action filed. You need to speak to the social worker handling your sister's case. If she cannot provide this information to you, try contacting the Office of County Counsel for the County where your sister was charged. There will be an attorney in charge of her case and they may be able to give you the name of the social worker. If that doesn't work, you need to contact the department of children and family services and try to locate the social worker.
