delivered the opinion of the Court.

On July 14, 1948 Epifania Pagán Hernández instituted in the lower court a proceeding for declaration of heirship alleging, briefly, that her father Felipe Pagán died intestate in the city of Ponce on June 2, 1948; that he left property to be divided; that at his death he was legally married to Juana Hernández, and that his sole and universal heirs were his legitimate children Eladio, Emilia, Juana Rai-munda, Gracia, Eleuteria, Epifania, Gumersindo, Fernanda and Luciano, all surnamed Pagán Hernández, and his aforesaid surviving spouse. She requested that the aforenamed legitimate children as well as his surviving spouse in the usufructuary share provided by the Act, be declared the sole and universal heirs of the deceased.

On the 23d of said month, Leonor, Eustacio and José-Juan Pagán Torres, Modesto, Luis and Luisa Pagán Colón alleging to .be acknowledged natural children of Felipe Pagán filed a motion for intervention in the said proceeding for declaration of heirship. They alleged that because they had been voluntarily recognized by their father they were entitled to the same share as that belonging to each *114one of the legitímate children who received no extra portion in the inheritance. In the same motion for intervention they impeached the marriage certificate of Felipe Pagán and Juana Hernández which appeared in the parochial registry of the city of Ponce because it was not the original marriage record but a recent reconstruction of a certificate the existence of which was unknown, and they maintained that said reconstruction was void for all legal purposes.

The petitioner opposed the interveners’ motion and denied that they were the natural children of the deceased since they had been born during the latter’s marriage to Juana Hernández effected in 1878 for which reason they had the status of adulterine children. The petitioner maintained that thé marriage certificate impeached by the inter-veners, which was reconstructed on June 18, 1948, was valid but that assuming that said certificate were null ■and void, Felipe Pagán and Juana Hernández always acted ;and behaved, from October 12, 1878 until the death of the .former on June 2, 1949, like husband and wife during their lives, recording the births of the children begotten by them as their legitimate children. Lastly she requested that her petition for the declaration of heirship be granted and that the motion of the interveners, who according to the petitioner were not entitled to any portion of the inheritance of the deceased, be dismissed.

A hearing was held in which both parties introduced documentary and oral evidence by virtue of which the lower court found that the deceased died intestate on the date alleged in the petition, that he had married Juana Hernán-dez and that the children had in said marriage were legitimate. The documentary evidence on which the marriage was established and proved — the petitioner desisted from proving said .point with the marriage certificate reconstructed on June 18, 1948, since she admitted that it was ineffective for said purposes— consisted in the birth cer*115tificates of the children wherein the deceased stated that they were his legitimate children and of his wife Juana Her-nández, as well as public deeds in which the deceased stated that he was married to Juana Hernández. There was oral evidence that both lived together and always acted in the community as married until the death of the deceased.

The lower court also found that the deceased had begotten the interveners outside his marriage to Juana Hernán-dez and that he had recognized them by separate affidavits duly sworn to and subscribed in July and October, 1945. Consequently, it rendered judgment granting the motion for the declaration of heirship as well as the motion for intervention and it declared as the sole and universal heirs of the deceased his legitimate children had in his marriage to Juana Hernández and the latter as his surviving spouse in the usufructuary share, and the interveners as his recognized natural children with all the rights granted to them by law.

Feeling aggrieved, the interveners appealed from said judgment to this Court and assigned the following errors: (1) that the lower court found that the marriage of Felipe Pagán and Juana Hernández had been proved by virtue of the uninterrupted living together of the parents as husband and wife together with the record of the birth of their children as legitimate children and (2) that it weighed the evidence erroneously.

Discussing their first assignment of error the appellants maintain that the lower court unduly applied § 86 of the Civil Code, 1930 ed.,1 sincé its provisions are only applicable to the marriages contracted after January 1, 1885 and not to those effected before said date, which, *116according to § 85 of said legal body2 shall be proven “in the manner established by former laws”, and that in any event the act of marriage should have been fully proved, before resorting, once the impossibility to produce the marriage certificate was established — as a result of a fire in the parish on September 25, 1880 — to secondary evidence.

Since it was alleged in this case that the marriage was effected prior to January 1, 1885, appellants are correct indeed in alleging that according to the first paragraph of § 85 of the Civil Code said marriage should be proven not by the means established by said legal body for marriages effected after said date but by the means established by former laws, as stated in § 85. However, the correct construction given by appellants to § 85 does not help their case for although the provision in § 86 that “the uninterrupted living together of the parents as husband and wife, together with the record of the birth of their children as legitimate children, shall be one of the means of proof of the marriage of the parents, unless it be shown that, either of them was bound by a previous marriage,” refers to marriages and to the case mentioned in the second paragraph of §85 of the Civil Code — marriages contracted after January 1, 1885 and in case it has disappeared from the book of marriages provided by the Civil Registry Act3 — it is a fact that the legislation in force in Puerto Rico prior to January 1, 1885 4 did not provide for secondary evidence to *117prove the marriage in case the parochial hooks should disappear.5 Under these circumstances the provisions of § 36 of our Code of Civil Procedure are applicable 6 since it provides how courts shall exercise their jurisdiction when there is no special proceeding fixed by law when it says that, in such cases, “if the course of proceedings be not specially pointed out by this Code or the statute, any suitable process or mode of proceeding may be adopted which may appear most conformable to the spirit of this Code”. And it is significant that Subdivision 29 of § 464 of said Code — § 102 of the Law of Evidence — establishes as a disputable pre*118sumption “That a man and woman deporting themselves as husband and wife have entered into a lawful contract of* marriage.

On the other hand, if the means of suppletory proof established by § 86 of the Civil Code to prove a marriage contracted after January 1, 1885 when the official proof of the marriage has disappeared, is an acceptable rule of law, it should also be accepted under § 36 of the Code of Civil Procedure to prove a marriage contracted prior to said date under the same circumstances since said means of proof is most conformable to the spirit of this Code. Thus, the first error assigned does not exist.

The second assignment is likewise untenable. The proof on the uninterrupted living together of the parents as husband and wife was contradictory but the trial judge was convinced that Felipe Pagán and Juana Hernández always lived together under the same roof and deported themselves at all times as married until the death of the former, begetting a large number of children who were recorded in the Civil Registry as legitimate. The evidence to that effect is sufficient to support the conclusion of the lower court which is strengthened even more by the fact that in all the sworn statements of acknowledgment of natural children on which appellants herein based their condition of heirs and their right to the inheritance of the deceased, the latter states that he is married to Juana Hernández; and in the affidavit of acknowledgment of Eustacio Pagán the deceased states that he is recognizing him “without prejudice to the interests of my legitimate children had in my marriage with Juana Hernández.” From an examination of the evidence in the record we are convinced that the judge acted correctly in weighing the evidence.

The judgment will be affirmed.
