In order for the lawyer representing the patient to be able to access HC data from the patient, it is necessary that he or she accredits their identity and empowerment in the health center, either through the form that the centre can articulate to resolve these applications, or, if applicable, through the provision of notary powers granted by the patient. It may be possible to communicate certain patient health data, without their consent, to the lawyers or insurance companies of the hospital or the professionals concerned, where this information is necessary for the exercise of the right of defence or the fulfilment of the insurance contract, as a result of claims relating to the health provision.
