delivered the judgment of the Court. The plaintiff relies upon an express promise by the defendant to pay for boarding his minor children. This promise was made after all the expenditures for which compensation is now demanded had been incurred, and the defendant says that it was nudum pactum ; that no damage having been sustained by the plaintiff and no benefit having accrued to the defendant in consequence of the promise, it is a promise without any consideration and of no validity.
To this the plaintiff replies, that the defendant was under a moral obligation to support his minor children, and that this moral obligation was a sufficient consideration for an express promise.
If the term moral obligation be used in its more extended sense, as embracing the whole circle of moral duties, and more especially if it include those imperfect obligations which the divine law enjoins, but which human laws do not reach, the plaintiff might well say that the defendant was under a moral obligation to contribute, within the extent of his means, at all times for the necessities of his children and even beyond the limits of their minority. But is this that kind of moral obligation which constitutes a legal foundation for an express promise ? To constitute a moral obligation the consideration for an exnress promise which may be enforced in a court of law, *431there must have been some preexisting legal obligation. This legal obligation may have ceased to have force by reason of some statute bar, as in the case of the statute of limitations, but there having been once a legal obligation, the moral obligation is sufficient to revive the liability by means of a new promise.
This subject was much considered by this Court in the case of Mills v. Wyman, 3 Pick. 207. That was a case where an adult son of the defendant, being in distress and in need of relief at a distance from home, was supplied by the plaintiff, and the plaintiff gave notice of the same to the father, who thereupon promised in writing to pay the expenses thus incurred. The plaintiff claimed to recover, on the ground that a moral obligation was a sufficient consideration for an express promise ; but the Court, after full consideration of the question and the authorities bearing on it, held the consideration insufficient and the promise not binding in law.
The principles of that case clearly establish the position, that the mere relationship between the defendant and his children did not per se furnish evidence of that degree of moral obligation sufficient to maintain an action on the express prom ise. The legal principles of that case, have been fully sanctioned in the case of Cook v. Bradley, 7 Connect. R. 57. Does the fact, that in the case now under consideration, the children were minors, necessarily change the nature of the consideration ? Is there a legal obligation on the father to pay the expenses of supporting his minor children in all places and under all circumstances, or is it an obligation somewhat limited in its character ? The general obligation of furnishing reasonable and adequate support for his children during the period of their infancy, is clearly by law devolved on the parent; but he has the right of providing for them under his own roof and in such a way as he may find most convenient and least burdensome to himself. It is well settled, that if a child voluntarily leaves his father’s house and without any sufficient occasion therefor, the father is not bound to provide for him elsewhere. In the language of the case of Angel v. M'Lellan, 16 Mass. R. 28, whenever the authority of the parent shall be abjured without any nec essity occasioned by the parent, all obligation to provide *432for tlie child has ceased. It would be no less true, that where the child was induced by another person to leave the family of the father without any necessity for so doing, the person thus influencing him to leave, would, in case he should furnish supplies, have no cause of action against the father. It is also very clear, that the liability of the parent for support furnished his children, does not always arise when his children have been provided for by others, although in so doing they have actual!} benefited the parent.
It becomes necessary therefore, in each case, to ascertain under what circumstances the supplies were furnished, before we can decide whether there was a sufficient consideration to create a liability on the part of the parent to pay for them. Upon looking into the report of facts in the present case, it is apparent that the plaintiff relies solely upon the ground that these supplies were furnished by him for the children of the defendant, and that the defendant subsequently promised to pay what the same were reasonably worth. The plaintiff does not show that any necessity existed for his interference, any want of full and adequate provision for the children at the house of their father, or any facts tending to prove that it was necessary to maintain them elsewhere. So far as it appears in the case, they left without the consent of the father, and without any fault on kis pa,t. There is an entire absence of all those circumstances that would create such an obligation as would furnish a legal consideration for an express promise. The proof of such facts must' come from the plaintiff. The burden is on him to show that there existed a necessity for furnishing these supplies, and that this necessity was occasioned by the defendant. The plaintiff having failed to do so, has furnished no sufficient evidence to maintain his action. The promise of the defendant was merely gratuitous and cannot be enforced in a court of law.
The verdict is set aside, and the plaintiff is to become nonsuit.
