Aranas vs. Mercado, G.R. No. 156407, January 15, 2014

The probate court is authorized to determine the issue of ownership of properties for purposes of their inclusion or exclusion from the inventory to be submitted by the administrator, but its determination shall only be provisional unless the interested parties are all heirs of the decedent, or the question is one of collation or advancement, or the parties consent to the assumption of jurisdiction by the probate court and the rights of third parties are not impaired. Its jurisdiction extends to matters incidental or collateral to the settlement and distribution of the estate, such as the determination of the status of each heir and whether property included in the inventory is the conjugal or exclusive property of the deceased spouse.
