delivered the opinion of the court.
This is an appeal from an order of the District Court of San Juan, Section 2, overruling a motion for change of Avenue.
The action is one of debt on a promissory note, which is copied into the complaint and reads as follows:
“$2,500, U. S. Cy. Due November 20, 1914.
“I promise to pay to Manuel López Gómez, or order, at his place of business in San Juan -on November 20, 1914, the sum of two thousand five hundred dollars for value received. The said sum shall bear interest at the rate of_annually from_until the date of its payment. I expressly submit myself to the jurisdiction of the Insular courts of San Juan and agree to pay the costs and expenses which may be incurred in the recovery of the said amount, including the fees of the attorney who may be employed to bring suit.
“San Juan, Porto Eico, May 20, 1914.
“José ToRo EiosN
The defendant having been summoned in Humacao, within the proper time he filed a demurrer on the sole ground that *598tiie complaint “is uncertain as regards tlie payment of interest at the rate of 6 per cent from November 20, 1914, inasmuch as such obligation does not appear upon the face of the note transcribed in the said complaint, the said complaint being uncertain in that respect.” On the same day on which the defendant filed the demurrer he also filed a motion for change of venue to the district court of his domicile on the ground that it was a personal action.
The court overruled the motion and undoubtedly its ruling was based on sections 76 and 77 of the Code of Civil Procedure, which sections, as we said in the case of Hernaiz, Targa & Co. v. Vivas, 20 P. R. R. 99, are of an origin different from that of the code as a whole. The provisions of said sections are inspired by articles 56, 57 and 58 of the old Law of Civil Procedure. For greater lucidity and in order to construe them correctly, we will compare the said statutes, then refer to the jurisprudence relating to the latter, and finally determine the scope and the effect of the former.
The sections cited from the Code of Civil Procedure now in force in this Island read as follows:
“Section 76. — In accordance with its jurisdiction, a court shall have cognizance of the suits to which the maintenance of all kinds of actions may give rise, when the parties may have agreed to submit the suit to decision of (such) court.
“Section 77. — The submission shall be understood to be made:
“1. By the written agreement of the parties.
“2. By the plaintiff through the mere act of applying to the court and filing the complaint.
“3. By the defendant when, after his appearance in court, he takes any step other than to request that the trial be held in the proper court.”
And those of tbe former Law of Civil Procedure are as follows:
“Article 56.; — Any judge impliedly or expressly agreed upon by the litigants shall be competent to take cognizance of the suits arising from actions of all kinds.
“This submission, however, can only be made to a judge exer*599cising ordinary jurisdiction and who is competent to take cognizance of questions similar to and of the same kind as the one submitted.
“Article 57. — By an express submission shall be understood that made by the parties in interest clearly and in definite terms renouncing their own rights (waiving the statutory jurisdiction), and unequivocally designating the judge agreed upon to determine the question.
“Article 58. — An implied submission is made:
“1. By the plaintiff, by the act of filing his complaint before the judge.
“2. By the defendant when, after his appearance is entered in the action, he takes any further steps therein, except to formally object to the jurisdiction of the judge by declinature.” (War Department translation).
As may be seen, section 76 of the new code is the same as article 56 of the old law. The final paragraph of the latter is condensed in the words “In accordance with its jurisdiction” of the former, and instead of the words “expressly or impliedly” of the first paragraph of article 56, section 76 refers to submission in general.
Section 77 of the new code includes all the cases covered by articles 57 and 58 of the former code, but, following the limitations of article 56, the Spanish legislators define in articles 57 and 58 cases of express and implied submission, while the Porto Rican legislators, in harmony with the provision of section 76, include in section 77 all cases of submission in general, although it is clear that subdivision 1 of section 77 covers express submission and subdivisions 2 and 3 of the same refer to implied submission, with the only difference that according to the present code an agreement in writing to that effect is sufficient to constitute submission, whereas under the old law it was necessary to waive the statutory jurisdiction and designate the court to which the parties submitted. The new code preserves the principle of the old law but clothes it in simpler form. Manifestly an express waiver of jurisdiction is unnecessary because the express submission of the parties clearly involves such waiver.
*600Let us now see wliat construction was placed upon the provisions of the old law. In commenting thereon Manresa says:
“Submission may be express or implied. It is express when tlio parties clearly and in definite terms waive the statutory jurisdiction and designate with all precision the court to which they submit themselves, and implied when by acts or steps taken before a court without jurisdiction they let it be understood that they submit themselves to its jurisdiction.
“In order that the submission may be understood as express and have the corresponding effect, there must be not the slightest doubt of the intention and will of the parties, not only as regards the waiver of the statutory jurisdiction, but also as to the court to which they wish to submit themselves. If either of these two conditions is lacking the submission will be ineffective, because article 57 of the law and articles 3 and 304 respectively of the two statutes heretofore cited require the union of the two conditions. Conjectures will not suffice. A general waiver of the customary kind usually made in some deeds will not be good. The waiver of the statutory jurisdiction must be stated clearly and in definite terms as must be also the designation of the court to which they submit themselves.
“It is best that after setting forth the nature of the transaction in the instrument executed for the purpose, the parties state-clearly and in a definite manner therein that they waive the statutory jurisdiction and agree to submit themselves to the jurisdiction of the court of first instance of such and such a place for the decision of any action or actions that may arise from the transaction, or from the enforcement of the said contract. Should there be two or more judges in that place, in accordance with article 59 which we shall review later, the submission must be made to any one of them and not to a particular one.” I Manresa, Law of Civil Procedure, 163.
In its judgments of June 11, 1858, April 5, 1861, June 6, 1872, and January 9, 1873, the Supreme Court of Spain lield that the waiver of jurisdiction is a lawful and permissible agreement and that when the parties to a contract waive the same therein and submit themselves expressly to the jurisdiction of a certain place, the judge of that place has exclusive jurisdiction of the matter.
As may be seen both from the jurisprudence of the Su*601preme Court of Spain and the opinion of the most distinguished of the commentators on the Law of Civil Procedure, two requirements must be complied with in order that the submission may be understood to be complete — namely, the waiver of jurisdiction and the designation of the court to which the contracting parties submit themselves.
Now, given the form in which the statute of Porto Rico is worded, is it necessary to .comply with -the two requirements to which Manresa and the Supreme Court of Spain refer? Prom the comparative study which we have made it may be clearly inferred that it is not. A written agreement to submit to a particular court having statutory jurisdiction over the subject-matter of the agreement is sufficient under the present laws of Porto Rico to bind the parties. And as such an agreement was made in the present case, it is necessary to conclude that the District Court of San Juan, Section 2, was justified in overruling the motion of the defendant for a change of venue, and that consequently its ruling should be affirmed by this court.
It would be unnecessary for us to prolong the review -of this case if the defendant had not cited in support of his motion for change of venue to the place of his domicile the American jurisprudence laid down in the case of Hall v. People’s Mutual Life Ins. Co., 6 Gray, 185, and Insurance Company v. Morse, 87 U. S. 445.
We have considered the cases cited and think that they are not applicable. In the new Code of Civil Procedure the Porto Rican legislators intended to preserve, and did preserve, the principle of the old code regarding previous submission of the parties. The said provision is clear and has been construed repeatedly, as we have seen, to mean that previous submission is a lawful agreement and when made in legal form is binding upon the person who submits himself, and even upon his heirs. Such construction was thoroughly understood and practiced in Porto Rico and is not «contrary to honesty, good usage or public policy. Appar*602ently the only difference between the American and Spanish jurisprudence is that according to the former an action must be begun before the party can submit himself, and according to the latter such submission may be agreed upon in the contract which may give rise to the action. Therefore, the principle of voluntary submission, which, in our opinion, is-the essential element, is recognized by the jurisprudence of both countries. For this reason, although our present Code* of Civil Procedure is almost entirely of American origin, its, sections 76 and 77 can easily subsist with their old construction. No fundamental right recognized by the present laws-is violated thereby, and the legislative intent, which undoubtedly was to preserve a familiar contractual formula in use-for many years in this Island, is complied with.
The hypothetical case that a person may be compelled perhaps to defend himself outside of the jurisdiction of his domicile because of a false document in which his submission appears, is not before us. In -the case before us for consideration and decision, the defendant, in basing his demurrer-on the sole ground that the manner of claiming the interest was uncertain, impliedly admitted the authenticity of the instrument in which his submission is shown.
Nor is any question involved here between Insular and Federal courts. This is a case referring to two courts created by the same Legislature which according to law have equal jurisdiction within their respective districts.
The order appealed from should be
Affirmed.
Chief Justice Hernández and Justices Aldrey and Hutchi-son concurred. Mr. Justice Wolf dissented.
