delivered tlie opinion of the court.
The appellant, Esteban Questel, brought an action in the District Court of Ponce on March 31, 1911, against the widow and children of Narciso Carreras Eivas as heirs of the latter, wherein he requested that he be declared the natural child of said Narciso Carreras Eivas, who died August 7, 1893, with the right, among such others as the law may grant him, to use his surname. This request was based on his having been born on August 24, 1876, of Juana Ceferina Questel while the latter lived in concubinage with Narciso Carreras Eivas, both being unmarried, such relation having existed until three years later, when his father married the defendant, Francisca Conde. The complaint also sets forth some facts tending to shows acts of acknowledgment on the part of his father.
The defendants filed as their sole allegation an answer in which they acknowledged the plaintiff as the natural child of Narciso Carreras Eivas, and therefore acquiesced in the complaint and requested the court to render judgment in accordance with the -prayer thereof, without taxing costs against them.
The plaintiff then asked the court to render judgment without further procedure, and the latter rendered such judgment, which was entered the same day, August 22, 1911, dismissing the complaint without costs. From said judgment the plaintiff took an appeal to this Supreme Court.
The appellant assigns in his brief filed with us, as errors of the trial court, that it erroneously interpreted section 199 of the Civil Code of Porto Eico in connection with section 137 of the former Civil Code, and that said court unduly applied, through an erroneous interpretation thereof, section 109 of the Code of Civil Procedure.
From the extensive written opinion of the court in support of its judgment, it is seen that the complaint was dismissed because, as it appeared therefrom that the right which was *729claimed was extinguished, it did not contain, sufficient facts to determine a cause of action.
Of course, if a complaint does not contain sufficient facts as grounds upon which, a court may decree: a right, the latter cannot be conceded, although the defendant may not oppose the complaint and may acquiesce in that the right demanded should he granted because the judgment would not he based on the law.
For this reason the court must examine the allegations in order to ascertain if they are sufficient to grant the: prayer, and even on appeal the court may investigate the sufficiency of the facts alleged in the complaint although the question has not been raised in the courts below.
The plaintiff, Esteban Questel, was born in March, 1876, and was, therefore, 17 years of age when, in 1893, Narciso Carreras Eivas died. In 1899 he attained full judicial capacity in accordance with the Spanish Civil Code then in force, but did not file his complaint until 12 years later — that is, in 1912.
Although the plaintiff was born under Law 11 of Toro, as he did not institute his action before the Spanish Civil Code became effective such action must be governed by the said law, but in the exercise thereof it must conform to the provisions of section 137 of the former Civil Code, as we have already decided in the case of Gual v. Bonafoux (15 P. R. R., 545.)
According to said section 137 of the Spanish Civil Code the child can institute an action for filiation or acknowledgment only during the life of its father, and should the latter die before the former attains his majority, then before the lapse of the first four years of his majority.
In accordance with this provision of law, Narciso Carreras Rivas having died when the plaintiff was 17 years of age and said plaintiff having attained his majority in 1899, the four years following such attainment expired in 1903.
As during that time the action was not instituted, but was *730instituted eight years later, the question now arises as to whether his right extinguished in such manner that a judgment in his favor cannot be legally rendered because of the insufficiency of facts to determine a cause of action, notwithstanding the fact that the defendants did not allege in their favor the prescription of the action, but, on the contrary, acquiesced in the complaint filed by the plaintiff.
The answer to this question will depend on the nature of the legal provision contained in the aforesaid section 137.
In the aforesaid case of Gual v. Bonafoux this court has said:
“The right of the plaintiffs, Luis and Alfonso, to recognition as natural children, and consequently the action for a declaration of this right, having arisen before the old Spanish Civil Code went into effect, both right and action must subsist with the extension and according to the terms recognized by the prior legislation; but neither can have a longer duration than that prescribed by the code.”
In the case of Armsterdam v. Puente (16 P. R. R., 527) this Supreme Court stated that—
“* * * every natural child under any condition who did not bring his action in time would find himself forever barred. ’ ’
In the case of Rijos v. Folgueras (16 P. R. R., 593) this court expressed its opinion as follows:
“When the parents do not recognize natural children in the manner mentioned, then the children must bring an action for filiation and obtain a judicial declaration of their right.
“If the parents and children were negligent, in such case they must suffer the consequences of their acts and blame themselves and not the law which regulated these questions, which are of such great social importance, in a uniform manner and for the good of all. ’ ’
Section 137 of the Spanish Civil Code was modified by section 199 of the Revised Civil Code, which prescribes that an action to claim filiation may be filed at any time within *731two years after the child shall become of age, and commenting on such provision, which is similar to the former, we have recently said, in the case of Isabel de Jesús v. Succession of Ramón Pérez Villamil:
“Now, then, the plaintiff having been born on November 19, 1880, became of age on the same day and month of 1901, when she reached the age of 21 years, which is the majority age fixed by section 317 of said code, and she did not bring this action of filiation until August 30, 1911, which is the date borne by the complaint. Her action had already expired and has been terminated by the lapse of time fixed by law. * * *. Notwithstanding the fact that she was capable of bringing this action from the time the said code went into effect she has failed to do it, and brought it when the period fixed by law had already expired. She was neither active nor diligent in the exercise of her rights, and she herself is to blame for the loss of that right and cannot blame the law that respects that right and only fixed the time within which the same should be exercised. * * *
“That law is not applicable to the case at bar, because when the same went into effect the present action of filiation had already expired in accordance with section 199 of the Revised Civil Code, and the former law cannot revive a right that is already dead.”
The preceding -citations show that this Supreme Court is of the fixed opinion that in accordance with section 137 of the Spanish Civil Code, as well as with 199 of the Revised Civil Code, the period for instituting an action for acknowledgment lasts only during the time fixed by law. On the expiration of these periods, therefore, the right extinguishes, ipso facto, and cannot revive.
It is true that in all those case's the defendant pleaded-prescription, and in the present case this was not done; but when, as we have said, the right extinguishes on the expiration of the period granted by law for the exercise thereof, although the defendant doe:s not allege prescription, the plaintiff shall not for that reason have a cause of action.
The provisions of the two sections above cited fix the lifetime of the father as the period within which the action must be brought, and, as an exception, if the child is a minor *732on the death of the father then the action must be brought before the lapse of the first four years after he attains his majority.
Considering the language' of such provision, it is impossible to extend the period more than the time specified by the law, because if the action could be instituted, owing to the fact that prescription had not been pleaded, after the death of the father, or after the said four years, the law would be openly violated because the action would be instituted after the death of the father and after the lapse of the first four years of majority. It is therefore a period which the consent of the defendant cannot extend.
In view of the foregoing the lower court did not commit the errors assigned and therefore the judgment should be affirmed.
Affirmed.
Chief Justice Hernandez and Justices MacLeary, Wolf and del Toro concurred.
