G.R. No. 167321 ; July 31, 2006
Epifanio San Juan, Jr., petitioner, vs. Judge Ramon A. Cruz, Regional Trial Court, Branch 224, Quezon City and Atty. Teodorico A. Aquino, respondents.

FACTS

Atty. Teodorico A. Aquino filed a petition for the probate of the will of Loreto Samia San Juan, which named Oscar Casa as a devisee. During the pendency of the probate proceedings, Oscar Casa died. The law firm of Aquino, Galang, Lucas, Espinoza, Miranda & Associates sought to enter its appearance for Federico Casa, Jr., who claimed to be an heir of Oscar Casa. The probate court initially denied this appearance, ruling that Federico Casa, Jr. was not the executor or administrator of Oscar Casa’s estate and thus could not be substituted as a representative under Section 16, Rule 3 of the Rules of Court. The court ordered Aquino to secure the appointment of an administrator for Oscar Casa’s estate.
In purported compliance, Aquino filed a document entitled “Appointment of Administrator,” signed by several individuals surnamed Casa, designating Federico Casa, Jr. as the administrator of the property Oscar Casa was to inherit from the will. Petitioner Epifanio San Juan, Jr. moved to declare this appointment inadequate, arguing that a court-appointed administrator of Oscar Casa’s estate was necessary for proper substitution.

ISSUE

Whether the heirs of a deceased devisee in a probate proceeding may designate a representative among themselves to be substituted for the deceased, absent a prior judicial appointment of an administrator for the deceased’s estate.

RULING

The Supreme Court ruled in the affirmative, denying San Juan’s petition. The legal logic centers on the interpretation of Section 16, Rule 3 of the Rules of Court concerning the substitution of a deceased party. The Court clarified that while the rule gives priority to the deceased’s executor or administrator (the legal representative), it does not prohibit substitution by the heirs if no administrator has been appointed. The heirs, from the moment of death, step into the shoes of the decedent with respect to his rights and obligations.
The Court distinguished the cited precedent, Lawas v. Court of Appeals, noting it involved a situation where an administrator had already been appointed, making substitution by the heirs improper. Here, no administrator for Oscar Casa’s estate existed. Consequently, the heirs could properly represent his interest in the probate of Loreto’s will. Their collective designation of Federico Casa, Jr. as their representative was a valid act of substitution, fulfilling the procedural requirement to ensure the estate’s representation and the protection of due process. The probate court’s order allowing this substitution was therefore correct. The need for a prior judicial determination of heirship was not a prerequisite for substitution under the circumstances of the case.
