Questions of law can be resolved without having to reexamine the probative value of evidence presented, the truth or falsehood of facts being admitted.[66] The instant case does not present a compelling reason to deviate from the foregoing rule, especially since both trial and appellate courts agree that respondent had proven her claim of ownership as against petitioners' claims. Their factual findings, supported as they are by the evidence, should be accorded great respect. In any case, even if petitioners' arguments attacking the authenticity and admissibility of the Deed of Quitclaim executed in favor of respondent's father are well-taken, it will not suffice to defeat respondent's claim over the subject property. Even without the Deed of Quitclaim, respondent's claims of prior possession and ownership were adequately supported and corroborated by her other documentary and testimonial evidence. We agree with the trial court's observation that, in the ordinary course of things, people will not go to great lengths to execute legal documents and pay realty taxes over a real property, unless they have reason to believe that they have an interest over the same.[67] The fact that respondent's documents traverse several decades, from the 1960s to the 1990s, is an indication that she and her family never abandoned their right to the property and have continuously exercised rights of ownership over the same. Moreover, respondent's version of how the petitioners came to occupy the property coincides with the same timeline given by the petitioners themselves. The only difference is that petitioners maintain they came into possession by tolerance of the Smith family, while respondent maintains that it was her parents who gave permission to petitioners. Given the context under which the parties' respective statements were made, the Court is inclined to believe the respondent's version, as both the trial and appellate courts have concluded, since her version is corroborated by the documentary evidence. Whether petitioners have acquired the subject property by prescription Assuming that the subject land may be acquired by prescription, we cannot accept petitioners' claim of acquisition by prescription. Petitioners admitted that they had occupied the property by tolerance of the owner thereof. Having made this admission, they cannot claim that they have acquired the property by prescription unless they can prove acts of repudiation. It is settled that possession, in order to ripen into ownership, must be in the concept of an owner, public, peaceful and uninterrupted. Possession not in the concept of owner, such as the one claimed by petitioners, cannot ripen into ownership by acquisitive prescription, unless the juridical relation is first expressly repudiated and such repudiation has been communicated to the other party. Acts of possessory character executed due to license or by mere tolerance of the owner are inadequate for purposes of acquisitive prescription. Possession by tolerance is not adverse and such possessory acts, no matter how long performed, do not start the running of the period of prescription.
