delivered the opinion of the court.
In a petition verified by Ms attorney, Eafael López Lan-drón, and filed in this court, Arturo Leopoldo Vázquez Prada y López applied for a writ of certiorari addressed to Jesús María Bossy, Judge of the District Court of San Juan, Section 2, and to Vicente Boceo and his wife, Eosa María Cesa-rino y JBrandy, praying that this court review and set aside the summary foreclosure proceedings prosecuted by the said conjugal partnership against the petitioner and others, because, although of age, the petitioner had not been summoned, heard, or defeated in the proceedings, notwithstanding which fact the property of which he is a joint owner was sold at public auction.
The writ having been issued and the record received accompanied by a brief of the trial judge in support of his procedure, a hearing was had at which the attorney for the petitioner and Herminio Díaz Navarro, the attorney who prosecuted the foreclosure proceedings in the lower court, appeared.
In the brief of the judge and in the argument of Herminio Díaz it was urged that this court should discharge the writ for the following reasons: Because the oath to the petition was insufficient; because the petitioner had an adequate, speedy, and effective remedy at law; finally, because from the initial complaint filed in,the proceedings, Arturo Leopoldo Vázquez Prada did not appear to be of age but a minor *183under the patria potestas of his mother, and the summons to make payment having been served upon her, it applied to her son under her guardianship and legal custody.
As to the first ground of objection, section 118 of the Code of Civil Procedure allows pleadings to be verified by the attorney in any of the three cases following: First, when the party is absent from the district where the attorney resides; second, where the party is unable to verify the pleadings for some other cause; third, when the facts are within the knowledge of the attorney. In this last case the attorney cannot swear upon information and belief and the doctrine laid down in the case of Silcox v. Lang, 78 Cal., 121, cited in support of the contention that the affidavit of López Landrón should be stricken out, is applicable. When the attorney verifies a pleading in either of the other two cases, as in the present instance, he is not limited to facts within his own knowledge. Nevertheless, when the verification is based both on facts within his own knowledge and others which he believes to be true on information or belief, he should state in the pleading sworn to or in the affidavit itself what facts are known in one manner and what in the other. Rivera v. Camara, 17 P. R. R., 503. In the present case neither the petition nor the affidavit fulfils this requirement, but as the writ was issued and there are other reasons why it should be vacated, we will disregard this defect.
From the proceedings had before the lower court it appears that a complaint was filed in summary foreclosure proceedings under the provisions of the Mortgage Law and its Regulations to recover a certain sum secured by a mortgage cm a house in this city and that when the petitioner filed his application for a writ of certiorari the encumbered property had been sold at public auction and awarded to the plaintiffs in payment of their credit. In view of these facts let us see whether the petitioner had an adequate, speedy, and effective recourse at law to secure the relief sought in this writ of certiorari.
*184The Supreme .Court has decided frequently that as the writ of certiorari is an extraordinary and privileged proceeding it cannot he granted when there is an adequate, speedy, and effective remedy at law for securing the same relief. It is true that in summary foreclosure proceedings for the recovery of mortgage debts no appeal is allowed the petitioner, but paragraph 6 of subdivision 3 of article 175 of the Regulations for the execution of the Mortgage Law provides that the claims of the debtor involving the nullity of the proceedings shall be heard in an ordinary action. Therefore, there can be no doubt that the petitioner has an ordinary remedy at law to secure the decree of nullity which he seeks by this extraordinary proceeding of certio-rari, and the only question to be considered is whether said remedy is adequate, speedy, and effective, because if it is not, then the writ of certiorari will lie notwithstanding the existence of the ordinary remedy.
In deciding this phase of the question it is well to bear in mind the decision in the case of Arpín v. del Toro, District Judge, 8 P. R. R., 276, as it is very similar to the present case. That was a case where in order to execute the judgment a servitude was created on property belonging to Arpín, who had not been a party to the action, and recorded in the registry of property, and the said Arpín having applied to this court for a writ of certiorari to secure the annulment of the servitude and its record in the registry, it was held that said writ did not lie because he had recourse to an ordinary action at law for the annulment of the record of the servitude and that of a preliminary injunction or restraining order in conjunction with said action in case it should be necessary to prevent the accomplishment of any act which might tend to damage the property. In the case at bar the provision of the Regulations for the execution of the Mortgage Law cited grants the person who seeks the annulment of the proceedings the right to retain the proceeds of the sale, and section 91 of the Code of Civil Procedure gives him the *185right to record a notice of the pendency of the action in the registry of property as notice to interested third parties, and all these remedies are adequate, speedy, and effective for securing the result of the suit. Therefore, in accordance with our ruling in the case of Arpin supra, we must conclude that the writ of certiorari invoked by the petitioner does not lie because there exists an adequate, speedy, and effective remedy at law to secure the nullity sought.
But we must say also that in deciding certiorari proceedings we cannot consider matters other than those upon which the trial court based its decision and that, therefore, it is. not proper to allege in the petition facts which were not at issue in the lower court. We mention this because the petitioner alleges in his petition as a fundamental ground thereof that although of age he was not summoned when that fact is not shown from the pleadings which the judge had before him in deciding the case. On the contrary, it appeared that he was a minor under the patria potestas of his mother, Luisa López Laborde, the defendant. •
For the foregoing reasons the writ of certiorari should be discharged.
Writ discharged.
