Chika sued Gringo, a Venezuelan, for a sum of money. The Metropolitan Trial Court of Manila (MeTC) rendered a decision ordering Gringo to pay Chika P50,000.00 plus legal interest. During the pendency of the appeal before the RTC, Gringo died of acute hemorrhagic pancreatitis. Atty. Perfecto, counsel of Gringo, filed a manifestation attaching the death certificate of Gringo and informing the RTC that he cannot substitute the heirs since Gringo did not disclose any information on his family. As counsel for Chika, what remedy can you recommend to your client so the case can move forward, and she can eventually recover her money? Explain. (2016 BAR)
