ERNEST G. LORENZEN* In Anglo-American law, a person intervening in the affairs of another will be responsible to the other party for any damage done in consequence of such intermeddling, but will derive no rights as a result thereof. Only when the intervention in another's affairs is dutiful, as Woodward calls it, 1 that is, is required by a sense of duty, though not by law, will the intervener by entitled to compensation if he has conferred a benefit for which the recipient ought to pay. Quite a different attitude with reference to the intervention in other's affairs, without mandate, is maintained by the civil law. Its doctrine of negotior:um gestio goes back in origin, it appears, to the praetorian edict in Rome, which regulated the rights of parties who had carried on litigation on behalf of absent friends. 2 In the course of time the rights and duties created by this edict were extended to ' other kinds of intervention in the affairs of others.^3 Justinian says concerning the purpose of negotiorum gestio in Institutes 3, 27, I : "Thus, if one man has managed the business of another during the latter's absence, each can sue the other by the action on uncommissioned agency; the direct action being available to him whose business was managed, the contrary action to him who managed it. It is clear that these actions cannot properly be said to ori~ate in a contract, for their peculiarity is that they lie only where one man has come forward and ll!anaged the business of another without having received any commission so to do, and that other is thereby laid under a legal obligation even though he knows nothing of what has taken place. The reason of this is the general convenience; otherwise people. might be summoned away by some sudden event of pressing importance, and without commissioning any one to look after and manage their affairs, the result of which would be that during their absence those affairs would be entirely neglected; and of course no one would be likely to attend to them if he were to have no action for the recovery of any outlay he might have incurred in so doing." As a result of the negotiorum gestio, the principal would have a direct action, the actio negotiorum gestorum directa, by means of which he could enforce whatever claims he might have against the

agent on account of the management of his affairs. The agent would have the contrary .action, the actio negotiorum gestorum con- traria, by means of which he could enforce his claims against the principal. The term negotiorum gestio is used sometimes in a narrower sense and sometimes in a wider sense. 4 In the narrower sense it refers to that kind of voluntary management of another's affairs as would entitle the agent to recover his expenses. When the requirements for the negotiorum gestio in the narrower sense do not exist, the principal may be able to hold the agent as a negotiorum gestor, but the latter can proceed against the principal, if at all, only in accor- dance with the quasi-contractual principles relating to the ·recovery of unjustified benefits.^5 The requirements of the negotiorum gestio in the narrower sense in Roman Law are the following: I. The agent must have carried on another's (the principal's) business in the interest of the principal. The "business" carried on might be an act of any kind. It might consist of the doing of some physical act, such as repairing a house, 6 providing support 7 or medicine, 8 or it might take the form of a juristic act, such as becoming surety for another, 9 paying his debts,l 0 etc. The business carried on must have been "another's." If the voluntary agent by mistake carried on his own affairs, believing they were another's, he would have, of course, no claim as negotiorum gestor against the other.n If the business carried on concerned both the agent and a third party, he could recover from the third party only if he could have protected his own interests without the other.^12 As a co-owner of property making repairs on the common property could not satisfy this requirement, he would have no action against his co-owner as negotiorum gestor for the recovery of the latter's share of the expense.l^3

ing whether a person acted as negotiorum gestor or as a mandatary under a tacit mandate. A person who believes that he has authority to act as a mandatary, but in fact is not authorized, either because no mandate was given him, or because it was void, or because the act in question was beyond his authority, may be a negotiorum gestor, and able to recover as such. 18 In the same manner, a guardian acting on behalf of a ward after the guardianship has terminated may be a negotiorum gestor. 19 The mandate must be from the principal, in order to prevent the mandatary or agent from being at the same time a negotiorum gestor. If the agent acted under a mandate from a third person, his rights and duties arising between himself and such principal would be enforced according to the rules governing mandate. But if in the execution of such mandate, the agent intended to act not only in behalf of the mandator, but also in behalf of X, he might be a nego- tiorum gestor with respect to the latter. Whether a subsequent ratification of the gestor's acts should be regarded as tantamount to a previous authorization, so as to preclude any action based upon negotiorum gestio, has given rise to much discussion. The Roman texts on the subject are contradictory. Ulpian appears to say that ratification always converts the negotiorum gestio into mandate, so that the action should be on the mandate. 20 Scaevola, on the other hand, would allow the gestor to sue with the actio negotiorum gestorum. 21 According to Buckland, the gestor might treat it as a mandate, but it does not become mandate ipso facto, so that it was not affected by the death of the principal. 22

There were a number of Roman texts in which the agent is denied the actio" negotiorum gestiorum contraria for reimbursement because it appeared that he did the act with no expectation of reimbursement, either because he acted from a spirit of liberality, or in order to fulfil a family obligation. In Digest 3, 5, 27, I, Modestinus says: "Where Titus maintained his sister's daughter out of natural affection, I gave it as my opinion that this afforded no ground of action against her." 23 In Code 2, I8, I2, it is stated that a son, whether emancipated or not, paying his father's debt, cannot recover the sum from his father, if he paid it donandi causa. 4· The agent could not recover his expenses if his intervention was contrary to the express will of the principal. The principal might not want the act to be done at all, or he might object to have it done by the particular agent. In these cases, it seems the agent could not recover the expense incurred. Some of the Roman jurists said that the agent could have an action against the principal to the extent that the expenditure had actually enriched him. 24 Others held that a person intervening in the affairs of another against this other's express will must be deemd to have acted donandi causa. Says Ulpian in Digest 3, 5, 8, 3: "Julianus discusses this case. There are two partners of whom one forbids me to carry on the management, and the other does not forbid me; shall I have a right of action on negotia gesta against the one who did not forbid me? ... Accordingly I hold that the proper view is that of Julianus, that there will still be a good action on negotia gesta against the one who did not forbid, it being always understood that the one who forbade is not to incur loss to the slightest degree either through his partner or directly."

advantageous to the principal, from the standpoint of the time of the agent's act. The mere _fact that it failed to result in ultimate benefit to the principal would not deprive the agent of his right to reimbursement for his expenses, provided he had used proper dili- gence in the performance of the act. This circumstance marks the difference between the rights of a negotiorum gestor in Roman Law and those of a party whose recovery is based upon principles of unjust enrichment. 29 The act must have been beneficial to the principal at the outset from an objective point of view. The agent's belief that it would be advantageous would not be sufficient. 30 An agent might increase the value of a thing belonging to the principal from an objective point of view, and yet by so doing confer no advantage upon the principal within the meaning of the law of negotiorum gestio. This would be the case where the agent repairs property belonging to the principal which the latter had abandoned on account of the cost incident to the repairs. Under those circum- stances, the agent could not recover the expense incurred. 31 If the agent spent more than he ought to, he can recover from the principal only the amount that was reasonably necessary.^32 If he expended money for acts that were altogether unnecessary, he could recover nothing. 33 In determining whether the act done or the outlay incurred was reasonable, the principal's point of view, tastes, etc. were to be consulted.^34

the principal. Physical absence, however, was not indispensable, inability to look after his affairs being sufficient. 35 Recovery might be had, of course, in accordance with the principles of unjust enrich- ment. If the foregoing requisites did not exist in Roman Law, the agent could recover his expense only if the principal approved the trans- action. It should be noted that in Roman law recovery could be had only for the outlay, not compensation for services rendered. Negotiorum gestio was looked upon as a sort of voluntary mandate, and mandate being necessarily gratuitous in Roman law, it was natural that the negotiorum gestor should be deemed to have rendered the services gratuitously. A negotiorum gestor in the narrower sense owes the following duties in Roman law. I. The agent must complete the work he has undertaken in behalf of the principal and is not relieved from such duty by the principal's death.3 7

damage to the principal. (negotiorum gestio necessaria). 48 In this case there is deemed to be a reasonable presumption that the principal would have approved the management, if the circumstances had been known to him. The danger which the agent intended to avert must have been real from an objective point of view, 49 and it is not sufficient that the agent in good faith regarded it as such. Recovery can be. had only for the necessary and proper expenses, that is, for .those expenses without which the threatening danger could not have been-averted. 50 Under the above conditions, the agent is entitled to reimbursement of his expenses, even if he did not attain his object and the transaction terminated disadvantage- ously to the principal, provided always that he used due diligence. 51 A distinction is made between the negotiorum gestorum necessaria and the negotiorum gestorum utilis. 52 The latter exists where the transaction is undertaken, not for the purpose of avoiding a loss to the principal, but in order to confer an advantage upon him. In this case recovery is allowed on principles of unjust enrichment, to the extent that the principal is still enriched at the time of the suit in consequence of the agent's management. The basis of liability in this case is thus unjust enrichment and not negotiorum gestio,& If the undertaking by the agent was not necessary and did not resqlt in positive benefit to the principal, the agent has no claim for reimbursement, but is responsible to the principal for any damage caused. 54 The above rules are modified where the principal has prohibited the management of the affair. In such a case, p:t:ovided the prohi- bition is a valid one, the expenses can not be recovered, although the affair was a necessary one. 55 Nor can recovery be had by the agent to the extent of the principal's actual enrichment.^56 This rule of the Roman law has been modified, however, to the extent that the agent is entitled to the benefit so far as it can be taken in natura. 57 Germany. The provisions of the German law relating to negotiorum gestio in general are found in sections 677 to 687 of the German Civil Code, which read as follows:

"Sec. 677. A person who takes charge of an affair for another without having received a 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. Sec. 678. If the undertaking of the management of the affair is opposed to the actual or presumptive wishes of the principal, and if the agent must have recognised this, he is bound to com- pensate the principal for any damage arising from his manage- ment of the affair, even if no fault is otherwise imputable to him. Sec. 679. 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 fulfilment of which is of public interest or a statutory duty to furnish maintenance to others by the principal would not be fulfilled in due time. Sec. 68o. If the management of the affair has for its object the averting of an imminent danger which threatens the prin- cipal, the agent is responsible only for wilful default and gross negligence. Sec. 68r. The agent 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 666 to 668 applicable to mandatary apply mutatis mutandis to the obligations of the agent. Sec. 682. Iftheagentisincapable of disposing, or limited in disposing capacity, he is responsible only under the provisions relating to compensation for unlawful acts, and to the return of unjustified benefits. Sec. 683. If the undertaking of the management of the affair is in accordance with the interest and the actual or presumptive wishes of the principal, the agent _may demand reimbursement of his outlay as a mandatary. In the cases provided for by 679 this claim belongs to the agent even if the undertaking of the management of the affair is opposed to the wishes of the principal. Sec. 684. If the conditions of 683 do not exist, the principal is bound to return to the agent all that he acquires through the management of the affair under the provisions relating to the re- turn of unjustified benefits. If the principal ratifies the manage- ment of the affair, the claim specified in 683 belongs to the agent. Sec. 685. The agent does not have any claim if he had not the intention to demand reimbursement from the principal. If parents or grandparents furnish maintenance to their de- scendants, or vice versa, it is to be presumed, in case of doubt, that there is no intention to demand reimbursement from the re- cipient.

Argentina. The Argentine Code provides that the principal is liable as a mandator if the affair has been usefully managed, although the advantage has later disappeared. 66 In this case the principal must pay the agent's expenses and indemnify him against any personal obligations .which he has incurred. 57 There is an express provision in the Code that the principal is not bound to pay for the agent's services.^68 If the affair was not undertaken usefully, or if its usefulness was uncertain at the time it was undertaken, the principal is liable, in the absence of ratification, only to the extent of his actual enrichment. 69 Although the affair was undertaken usefully, the principal is, in the absence of ratification, liable only to the extent of his actual enrichment if, (r) the agent believed that it was his own affair; (2) the affair was a common one, but the agent acted solely in his own interest; (3) the principal is a minor or other- wise incapable, and his legal representative did not ratify the trans- action; (4) if the agent undertook the management out of gratitude as a remuneratory service. 70 Unless the agent had a legitimate interest in intervening in the principal's affairs, he cannot recover his expenses for any act done against the principal's express prohi- bition. Brazil. Where the affair has been usefully administered, the principal must perform the obligations contracted in his name and reimburse the agent for all his necessary or useful expenses. 72 The same is true where the object of the intervener's act was to prevent some imminent danger to the principal or where the intervention

resulted in benefit to the owner. In the cases just mentioned the amount of recovery cannot exceed, however, the benefits conferred. 73 Even where the agent engaged in risky operations, the principal must pay his necessary expenses and indemnify him against damages incurred, if he wishes to take advantage of the management of the affair. 74 Although the principal disapproves the agent's act, as
actual benefits conferred upon the principal. 75 Chile. If the affair has been well administered, the principal is under a duty to fulfil the obligations which the agent has contracted in the course of the management of the principal's affairs and reim- burse him for the useful or necessary expenses. 76 The principal is under no duty to compensate the agent for his se~ces. 77 If the affair has been administered badly, the agent is responsible for the damages caused. 78 If the agent administered the principal's afairs against the latter's express prohibition, the agent has no claim against the principal, unless the administration was actually useful to the principal and the benefits still exist at the time of the suit. 79 An agent administering the principal's business in the belief that it was his own, has a right to be reimbursed to the extent that the principal has been enriched and is still enriched at the time of the suit. 80 From the foregoing account it is apparent that a voluntary agent may recover under some circumstances the expenses which he has incurred, although no actual benefit but loss has resulted to the principal from the intervention, and that under other circumstances he may recover to the extent of the benefits conferred. We cannot stop to inquire in what respects the civil law differs from Anglo- American law in allowing in cases of this sort recovery on the ground of unjust enrichment. It has been pointed out that a dispute existed among the Roman jurists concerning the question whether recovery in quasi-contracts should be allowed on the ground of unjust enrich- ment where the act was done by the agent against the principal's prohibition, and that according to the prevailing view, the agent was deemed to have donated such benefit to the principal. 81 In modem times a contrary conclusion has been reached in continental countries on the ground that the intention to make a gift cannot be presumed, so that the agent may recover, notwithstanding the fact that the act was prohibited directly by the principal. The rule that

the intervention, although owing to unfortunate circumstances no advantage accrued therefrom to the principal in the end. Accord- ing to the German Code, the agent can demand reimbursement as a mandatary, if the undertaking of the management of the affair was in accordance with the interests and the actual or pre5¥med wishes of the principal. 87 Under the .German Code the agent must show, (r) that the management of the affairs of another was objec- tively in the interest of the principal, and (2) that it accorded with the actual or presumed wishes of the principal. If the intervention is not in the interest of the principal from an objective point of view, that is, judged by the views of ordinary men, the agent is not entitled to his expenses, although he was not in a position to ascertain what the intention of the principal was. In order to protect the principal, however, against unwelcome meddling in his affairs, for he may not want the act to be done at all, or may not want to have it done in the particular manner, or by the particular agent, or at the particular time, it was felt that that intervention should correspond also to the principal's expressed or implied will. A transaction might be objec- tively in the interest of the principal and yet be opposed to his will. On the other hand, if it appears that the intervention conforms to the principal's real will, there will be a conclusive presumption that it corresponds likewise with his interest. If the principal had no knowledge of the facts, so that he could have no real will in the matter, the presumed will of the principal will have to be ascertained by the court. In determining such will all the surrounding circum- stances are to be considered without reference to the fact whether they were known to the agent. 88 On grounds of social policy the German law overrides the princi- pal's will, however, in two classes of cases. First, where, without the management of the affair, a duty of the principal, the fulfillment of which is of public interest, would not be fulfilled in time; second, where a statutory duty to furnish maintenance to others by the principal would not be fulfilled in time.

general rule that the agent cannot recover his expenses against the expressed will of the principal is stated in such general terms that it might be given a most extensive meaning. The text does not speak of public duty but of a duty of the principal, the £u1fillment of which is of public interest. It might be contended, therefore, that the prompt discharge of any private obligation would be of general public interest, and thus authorize intervention against the will of the party obligated. But this is not the meaning of this section. 89 The application of the section is not limited, on the other hand, it seems, to the discharge of public duties. The essential thing appears to be that the prompt discharge of the obligation, whether public or private, shall be of public interest. 90 In the case of private obliga- tions, this will be true only under very exceptional circumstances, as for example, in the case of the burial of the dead. 91 It has been contended that the discharge of public duties is always of public interest ;^92 but this is denied by leading writers who claim that even in the case of obligations of the public law the special condition must exist that the £u1fillment of the particular obligation is of public interest. 93 The opposing will of the principal is disregarded in the second place, if without the intervention by the agent, a statutory duty of the principal to furnish maintenance to others would not be £u1filled in time. In this case it is not necessary to prove that the £u1fillment of the duty was in the public interest, for the existence of such interest is conclusively presumed. 94 The· negotiorum gestio implies that the agent acted in behalf of another. In France there has been a tendency to hold that there can be no negotiorum gestio without an "intention" on the part of the agent to carry on another's business. 95 This appears to have been

useful service to another. If he is conscious of this fact, the inter- vention is not egotistical, although he was pursuing his own interests at the same time or believed that he was under a contractual duty. Whether an intervention is egotistical or altruistic will depend, therefore, according to Picard's formula, upon the utility and necessity of the intervention.too In Germany it is held that the agent must act with a consciousness and will that the affair, in which he intervenes, is "foreign" to him.^101 The fact that the agent has a personal interest in carrying on another's affairs does not prevent its being a case of negotiorum gestio, for the performance of the agent's personal obligation may involve at the same time the management of another's affair. 102 It is not essential that at the time of acting, the agent had a particular princi- pal in mind. The will to act for whom it may concern su.ffices. 103 A person may be a negotiorum gestor, therefore, for a corporation or a partnership to be formed. 104 If a person treats another's business as his own, either because he mistakenly thinks it is his own, or because he wishes to make it his own, although he knows that it is objectively another's, he cannot recover as a negotiorum gestor, but may be held as such. 105 Where a person acts in behalf of another in execution of a mandate from a third party, or by reason of some public or private relationship which obligates him to act, he will ordinarily not be negotiorum gestor, as the intention to act in behalf of another will be lacking. A mandatary, for example, intends to act as such in behalf of his mandator, and not as negotiorum gestor. An official acting within his official duties generally does not intend to act in addition as a private negotiorum gestor. It is possible, however, that under particular crcumstances, such a person intends to act as negotiorum gestor for another, for example, if there should be a doubt in his mind concerning the validity of the mandate or such other relationship. 106 When a person transacts at the same

time his own business and that of another, either as co-owner or partner, the rule governing co-ownership or partnership will control. 107 The traditional rule has been that the agent intervening in the affairs of another could recover only his outlay, and not compen- sation for services rendered. In modern times, however, compen- sation has been allowed where the agent rendered professional services. 108 The negotiorum gestio of the Roman and modem civil law is an institution midway between mandate and quasi-contracts. In some countries, like Germany, it seems to approach more closely to mandate, whereas in others, France for example, it is identified more fully with quasi-contracts. The boundaries of the negotiorum gestio are everywhere ill-defined. The codes generally give no defi- nition, and leave the working out of the concept to the courts and writers. Although a vast literature has accumulated on this subject and a large body of decisions exist, it is not possible, in the nature of things, to state in precise but general terms what is meant by carrying on another's affair within the meaning of the doctrine of negotiorum gestio. The formulas suggested have been many, but little helpful in the solution of concrete problems. Assuming the conditions of negotiorum gestio within the meaning of the term in a particular country to be present, the agent can recover his outlay to the extent that the principal has been enriched. Such recovery seems to be allowed, although the intervention was against the direct prohibition of the principal. If the conditions are present which have been called in this article negotiorum gestio in the narrower sense, the agent can recover his outlay as such, provided it was necessary or proper, without reference to the fact whether it resulted in benefit or loss to the principal. This is the feature of the negotiorum gestio which is its most distinctive characteristic and stands out in striking contrast with Anglo-American law. The above represent some of the technical rules that have been developed in connection with the subject of negotiorum gestio. These convey, however, only a very inadquate idea of the importance and function of the negotiorum gestio in the modem civil law. These can be appreciated only through a study of its relation to the general system of law of which it forms a part. The negotiorum gestio has been found to be a very flexible and useful tool for the promotion
