VIII. Aldrin entered into a contract to sell with Neil over a parcel of land. The contract stipulated a P500,000.00 down payment upon signing and the balance payable in twelve (12) monthly installments of Pl00,000.00. Aldrin paid the down payment and had paid three (3) monthly installments when he found out that Neil had sold the same property to Yuri for Pl.5 million paid in cash. Aldrin sued Neil for specific performance with damages with the RTC. Yuri, with leave of court, filed an answer-in-intervention as he had already obtained a TCT in his name. After trial, the court rendered judgment ordering Aldrin to pay all the installments due, the cancellation of Yuri's title, and Neil to execute a deed of sale in favor of Aldrin. When the judgment became final and executory, Aldrin paid Neil all the installments but the latter refused to execute the deed of sale in favor of the former. Aldrin filed a "Petition for the Issuance of a Writ of Execution" with proper notice of hearing. The petition alleged, among others, that the decision had become final and executory and he is entitled to the issuance of the writ of execution as a matter of right. Neil filed a motion to dismiss the petition on the ground that it lacked the required certification against forum shopping.
