Short answer. The judge needs satisfactory proof, given in open court, that the hearing order's publication was done as directed and that the petition's allegations are true; only then, if proper and reasonable cause appears, does the court adjudge the name change as prayed for.

What the law says

Upon satisfactory proof in open court on the date fixed in the order that such order has been published as directed and that the allegations of the petition are true, the court shall, if proper and reasonable cause appears for changing the name of the petitioner, adjudge that such name be changed in accordance with the prayer of the petition.

The evidentiary threshold

The court needs satisfactory proof in open court on the date fixed in the order of two specific things: that such order has been published as directed, and that the allegations of the petition are true. The proof must be presented at the hearing itself, on the date the order fixed, not submitted informally beforehand or supplied afterward — this is the petitioner's actual opportunity to establish, on the record, both compliance with publication and the truth of what the petition alleges.

The substantive standard beyond proof

Even truthful, properly published allegations are not automatically enough. The court still needs proper and reasonable cause for the change before it will grant the petition — proof of the facts alone does not entitle the petitioner to a favorable judgment. This preserves judicial discretion over the ultimate question of whether a name change should be allowed at all, so the court is weighing the merits of the request, not merely checking boxes on procedural compliance and factual accuracy.

What the judgment tracks

If granted, the court adjudges that the name be changed in accordance with the prayer of the petition, so the relief matches exactly what was requested. The judgment does not grant some broader or different change than what the petitioner specifically asked for in the petition, which is one reason the petition itself has to state precisely what new name is being sought, rather than leave it to the court's discretion to select one.

Practical relevance today

This judicial standard still governs changes not covered by the administrative process under Republic Act No. 9048 and Republic Act No. 10172, such as a surname change, where the petitioner has to satisfy this same proof-and-cause test in court. Those two laws moved many first-name and clerical-error corrections to the civil registrar, but they did not remove judicial name-change petitions from the picture entirely — for the categories still requiring a court proceeding, Rule 103's publication, proof, and proper-cause requirements continue to apply in full.
