delivered the opinion of the court.
The plaintiff-appellee, Agustín M. de Andino, brought an action of unlawful detainer in the District Court of San Juan, Section 2, on April 28, 1917, against the defendant-appellant, Juana Canales, alleging that he was the owner of a house and lot situated in the ward of Cataño, of the municipality of Bayamón, of which the defendant was in possession at sufferance without paying any rent or other consideration, wherefore he prayed for a judgment of eviction, with the costs, expenses and disbursements of the action.
The defendant answered the complaint, denying its material allegations, and as new matter of defense alleged that she was the owner of the property in question, having acquired half of it as her interest in an industrial partnership' into which she had entered more than 42 years before with Pablo Figueroa Diaz, he being a tailor and she a dressmaker, and having acquired the other half by virtue of a conveyance made to her by Ramona Figueroa, the heir of the said Pablo Figueroa. The defendant also alleged that she was in the quiet, public, peaceful and uninterrupted possession of the *263property sir.ee the death of Pablo Figueroa, and that they jointly ho\l such possession during' his life.
The court entered judgment on March 23, 1918, sustaining the complaint and ordering the eviction of the defendant Juana Canales, who appealed from that judgment to this court.
The only question to be decided herein is whether the defendant is in possession at sufferance of the property to which the defendant has a dominion title.
The evidence of the plaintiff tends to show that he is the owner of the house and lot in question by virtue of a deed of purchase and sale executed to him on December 24, 1915, by Teresa and Encarnación Díaz and that the vendors had acquired the lot by a grant made to them by The People of Porto Rico in a public deed of September 30, 1915, and the house by inheritance from their deceased brother, Pablo Figueroa Diaz, whose intestate heirs they were adjudged to-be by the court. The evidence of the defendant tends to show that she and Pablo Figueroa lived together under the same roof for more than forty years, Figueroa being a tailor and the defendant a dressmaker, and that they worked together on equal shares in the expenses and profits, during which community life they erected with the savings of both the house in which they lived until the death of Pablo Figueroa on May 2, 1908, and which the defendant occupied thereafter continuously.
"We have already said in the case of Torres et al. v. Pérez, 18 P. R. R. 557, wherein the plaintiff introduced a recorded title to prove the ownership claimed by him, that “an action of unlawful detainer is a special proceeding * * * is not a proper one to decide the right of ownership, and for that reason when the defendant alleges some title to the possession of the property, unless all evidence to sustain such allegation is lacking, ejectment should not be decreed and the question of legal title to the property should be settled in *264an ordinary action before tire action of unlawful detainer can be brought.”
The evidence examined at the trial does not warrant the conclusion that the defendant is in possession of the property in question at su'fference, or without any title, for she alleges that she is in possession as owner, and such allegation, at least as to her having an interest in the' ownership of the house, is not wholly unsupported by the evidence.
According to a judgment of the Supreme Court of Spain of May 29, 1906, 104 J. C. 424, which doctrine was accepted by us in Veve et al. v. Fajardo Sugar Growers’ Association, 18 P. R. R. 277. “the action of unlawful detainer lay only when betwéen the^ lessee and lessor, or the owner of the estate and the person who occupies it at sufferance, there exist no legal relations other than such as are derived from said character, and when with respect to them no reasonable doubts are raised requiring an examination and discussion possible only in the prosecution of the proper declaratory action. ” '
Concerning the legal relations between the plaintiff as owner and the defendant as tenant at sufferance, there are reasonable doubts derived from other relations existing between Pablo Figueroa and Juana Canales on account of their having- lived and worked together, each for the benefit of both, during which time they built with their common funds the house in question. In the face of these doubts we cannot but conclude that there exists an antecedent question of law of great importance which cannot be decided in an action of unlawful detainer lacking the securities of defense and pleading offered by declaratory actions.
It is true that the defendant did not introduce direct evidence to show that she entered into an industrial partnership with Pablo Figueroa Diaz, according to the specific allegation of her answer; but it is to be observed that she denied generally the material allegations of the complaint, thereby denying that she was a tenant at sufferance, and *265under tills general denial any evidence could be introduced to show that she was not sucli tenant. As we have already said, she did introduce such evidence and it was admitted without objection on the part of the plaintiff.
For the foregoing reasons the judgment must be reversed, reserving to the plaintiff whatever rights he may have to sue in the proper action.
Reversed.
