Leonides Lopez Liso v. Manuel Tambunting

Summary

This case involves Dr. Leonides Lopez Liso's claim for P2,000 in medical fees against Manuel Tambunting for services rendered to defendant's daughter. The Court of First Instance awarded P700, finding it the reasonable value based on plaintiff's initial demand. The key issue was whether defendant had already paid, as he possessed plaintiff's receipt. Despite the legal presumption that possession of a receipt by the debtor indicates payment, both courts found sufficient contrary evidence. The Supreme Court affirmed, emphasizing that legal presumptions can be overcome by preponderance of evidence and that the receipt was sent for collection, not as voluntary surrender of the obligation. The decision establishes important precedent regarding the rebuttable nature of payment presumptions in contractual obligations.
