ANY INTERESTED PERSON MAY OPPOSE THE ISSUANCE OF LETTERS TESTAMENTARY:

     An "interested person" has been defined as one who would be benefited by the estate, such as an heir, or one who has a claim against the estate, such as a creditor. The interest must be material and direct, and not merely indirect or contingent. (Edgar San Luis vs. Felicidad San Luis, G.R. No. 133743, February 6, 2007, Rodolfo San Luis vs. Felicidad Sagalongos, G.R. No. 134029, February 6, 2007, YNARES-SANTIAGO, J.).
