With an advance directive, you appoint one or more trusted persons to act on your behalf in the event of incapacity. The advance directive is subject to the same formal requirements as a will (personal signature or public certification). The place of deposit of the advance directive can be registered with the civil registry office. The person of trust takes care of current contracts and legal matters, your assets and personal care such as the choice of a care place or support in everyday life.
You can designate a natural person (for example, a close person or an attorney) as well as a legal entity (for example, a trust office or a legal consultancy) or even several persons as a trusted third party.
