G.R. No. L-16553 - De Jesus vs. De Jesus

The intestate estate of Melecio de Jesus was the subject of proceedings under Special Probate Case No. 1960.
An inventory of the estate was filed by the administratrix, Ines Alejandrino, on March 10, 1948. This inventory included Lot No. 931 of the Cadastral Survey of Hermosa, Bataan, measuring approximately 155.9334 hectares, which was covered by Transfer Certificate of Title No. 1044 registered solely in the name of the deceased.

On May 22, 1948, Eusebia de Jesus, the deceased’s sister, filed a verified monetary claim against the estate amounting to P7,585.84.
Instead of having the monetary claim heard, on May 24, 1948, a stipulation of facts was entered into by the following parties:

The stipulation of facts acknowledged the common ownership of Lot No. 931 by Melecio de Jesus, Eusebia de Jesus, and Cirilo de Jesus, with the property being held solely in the name of the deceased in trust for all co-owners.
On the same day (May 24, 1948), a “Supplementary Stipulation of Facts” was executed wherein Eusebia de Jesus agreed to waive her monetary claim against the estate, contingent on the court’s approval and finalization of the earlier stipulation.
The agreements were presented to the court for approval with the expressed objective of preserving familial bonds and preempting future litigation.
On May 25, 1948, the probate court granted approval of both agreements.

In July 1955, Ines Alejandrino was replaced by her son, Leon de Jesus, as the administrator of the estate.
Acting as administrator and joining his mother, Leon de Jesus filed a complaint on October 11, 1958 (Civil Case No. 2563), seeking annulment of the stipulations entered on May 24, 1948.
The grounds for annulment were:

Lack of jurisdiction on the part of the probate court in approving the agreements.
Failure to provide notice to all interested parties, particularly the heirs of the deceased, who were largely minors at that time.

Defendants opposed the complaint, raising defenses of res judicata and prescription.
On December 16, 1958, the trial court sustained the motion to dismiss the complaint.
The plaintiffs subsequently appealed to the Supreme Court, contesting the validity of the approvals and arguing that proper notice as required by law was not given to all heirs.

Whether the probate court had the jurisdiction to approve the stipulations concerning the conveyance of Lot No. 931.
Whether the probate court’s power under section 9, Rule 90 of the Rules of Court extended to authorizing conveyances of property held in trust by the deceased.

Whether the lack of notice to all interested parties, particularly the heirs (many of whom were minors), invalidated the probate court’s approval of the stipulations.
Whether failure to appoint a guardian ad litem for the minor heirs affected the validity of the notice and, consequently, the agreements.

Whether the trial court erred in holding that Leon de Jesus, acting as administrator, could not question the agreements entered into by his predecessor, Ines Alejandrino, on the basis of estoppel.
