TUMALAD V. VICENCIO
41 SCRA 143
Vicencio and Simeon executed a chattel mortgage in favor of plaintiffs Tumalad over their house, which was being rented by Madrigal and company. This was executed to guarantee a loan, payable in one year with a 12% per annum interest.
The mortgage was extrajudicially foreclosed upon failure to pay the loan. The house was sold at a public auction and the plaintiffs were the highest bidder. A corresponding certificate of sale was issued. Thereafter, the plaintiffs filed an action for ejectment against the defendants, praying that the latter vacate the house as they were the proper owners.
Certain deviations have been allowed from the general doctrine that buildings are immovable property such as when through stipulation, parties may agree to treat as personal property those by their nature would be real property. This is partly based on the principle of estoppel wherein the
principle is predicated on statements by the owner declaring his house as chattel, a conduct that may conceivably stop him from subsequently claiming otherwise.
In the case at bar, though there be no specific statement referring to the subject house as personal property, yet by ceding, selling or transferring a property through chattel mortgage could only have meant that defendant conveys the house as chattel, or at least, intended to treat the same as
such, so that they should not now be allowed to make an inconsistent stand by claiming otherwise.
