Section 1 - Sources of Obligations
Sub-section 3 Management Of Affairs Without Mandate
A person, who manages an affair of another person without a mandate or obligation, shall manage the affair in conformity with the principal's expressed or presumptive wishes and in the manner beneficial to the principal.
The manager shall notify the principal without delay at the beginning of the management in so far as the notice is possible. If there is no urgency, he shall wait for the instructions of the principal.
The provisions of Articles 540 to Article 542 concerning Mandate shall apply mutatis mutandis to Management of Affairs without Mandate.
If the undertaking of the management of the affair is against the principal's expressed or presumptive wishes, the manager is bound to compensate the principal for any injury arising from his management, even if no negligence is in his act.
The provision of the preceding paragraph shall not apply if the undertaking of the management of the affair is in order to fulfill an obligation of public interests for the principal or to fulfill a statutory duty of the principal to furnish maintenance to others, or the principal's wishes are against the public policy or morals.
If the undertaking of the management of the affair is in order to avert an imminent danger which threatens the life, body or property of the principal, the manager is not responsible for any injury derived from his management, except in case of bad faith or gross negligence.
If the management of the affair is beneficial to the principal and is not against his expressed or presumptive wishes, and where the manager has, for the principal, made necessary or beneficial expenses, or assumed debt, or suffered injury, he is entitled to claim against the principal for the reimbursement of such expenses plus interest commencing from the date of outlay, or the payment of such debt, or compensation for the injury sustained.
In the cases provided by the second paragraph of Article 174, the manager may still have the claim in the preceding paragraph, even if the undertaking of the management of the affair is against the principal's wishes.
If the management of the affair does not accord with the provisions of the preceding article, the principal may still be entitled to the interests derived from the management. But the obligation specified in the first paragraph of the preceding article of the principal towards the manager shall be only to the extent of the interests he acquired.
The provision of the preceding paragraph shall apply mutatis mutandis to the situation when the manager knew it was another person's affair but still managed for his own interests.
If the management of the affair is acknowledged by the principal, unless otherwise expressed by the parties, from the beginning of the management, the provisions concerning Mandate shall be applied.
