Management of Affairs Without Mandate
Section 395. Management of Affairs without Mandate
A person who takes charge of an affair for another without having received mandate from him or being otherwise entitled to do so in respect of him, shall manage the affair in such manner as the interest of the principal requires, having regard to his actual or presumptive wishes.
Section 396. If the Principal opposed Management
If the undertaking of the management of the affair is opposed to the actual or presumptive wishes of the principal, and if the manager must have recognized this, he is bound to compensate the principal for any damages arising from his management of the affair, even if no fault otherwise imputable to him.
Section 397. Duty to the Public Interest
The fact that the management of the affair is opposed to the wishes of the principal is not taken into consideration if, without the management of the affair, a duty of the principal the fulfillment of which is of public interest or a legal duty to furnish maintenance to others by the principal would not be fulfilled in due time.
Section 398. Averting Imminent Danger
If the management of the affair has for its object the averting of an imminent danger which threatens the person, reputation or property of the principal, the manager is responsible only for willful default and gross negligence.
Section 399. Notification to the Principal
The manager shall notify to the principal, as soon as practicable, the undertaking of the management of the affair, and await his decision, unless there is danger in delay. For the rest the provisions of Sections 809 to 811 applicable to an agent apply mutatis mutandis to the obligation of the manager.
Section 400. Incapacitated Manager
If the manager is incapacitated, he is responsible only under the provisions relating to compensation for wrongful acts, and relating for the return for undue enrichment.
Section 401. Right to Reimbursement by Manager
If the undertaking of management of the affair is in accordance with the interest and the actual or presumptive wishes of the principal, the manager may demand reimbursement of his outlay as an agent. The provisions of Section 816 paragraph 2 apply mutatis mutandis.
In the case provided for by Section 397 this claim belongs to the manager even if the undertaking of the management of the affair is opposed to the wishes of the principal.
Section 402. Undue Enrichment
If the conditions of the foregoing section do not exist, the principal is bound to return to the manager all that he acquires through the management of the affair under the provisions relating to the return for undue enrichment.
If the principal ratifies the management of the affair, the provisions of this Code concerning Agency apply mutatis mutandis.
Section 403. Intention for Reimbursement
The manager has no claim if he had not the intention to demand reimbursement from the principal.
If parents or grandparents furnish maintenance to their descendants, or vice versa, it is to be presumed, in case of doubt, that there is no intention to demand reimbursement from the recipient.
Section 404. Third Party Management
If the manager acts for one person, believing that he is acting for another person, only the former has the right and duties arising out of the management.
Section 405. Management of Affair in the Belief that it is his Own Property
The provisions of the ten foregoing sections do not apply, if a person takes charge of the affair of another in the belief that it is his own.
If a person treats the affair of another as his own, although knowing that he is not entitled to do so, the principal may enforce the claims based on Sections 395, 396, 399 and 400. If he does enforce them, he is liable to the manager as provided for in Section 402 paragraph 1.
