No court should interfere with the probate court

The orders of the Regional Trial Court, Branch 26, in Civil Case No. 13207 setting aside the probate proceedings in Branch 23 (formerly Branch 11) on the ground of extrinsic fraud, and declaring Concordia Villanueva to be a co-heir of Celedonia to the estate of Esteban, Jr., ordering the partition of the estate, and requiring the administratrix, Celedonia, to submit an inventory and accounting of the estate, were improper and officious, to say the least, for these matters lie within the exclusive competence of the probate court
