Kalaw vs. Relova

When the sole substantial provision of a holographic will is altered without the required authentication by the testator's full signature, the entire will is voided because no valid provision remains; the original unaltered text cannot be given effect as doing so would disregard the testator's change of mind.

The case involves the probate of a holographic will executed by Natividad K. Kalaw, where the testatrix altered the dispositive provision to change her sole heir from her sister (Rosa) to her brother (Gregorio) without complying with the statutory requirement of authenticating the changes with her full signature.

• Original Filing: Court of First Instance (CFI) of Batangas, Branch VI, Lipa City (Probate Proceeding)
• Lower Court Decision: September 3, 1973 — Denied admission to probate of the holographic will due to lack of authentication of alterations under Art. 814 of the Civil Code. November 2, 1973 — Denied motion for reconsideration.
• Appeal: Directly to SC via Petition for Review on Certiorari
• SC Action: Rosa K. Kalaw filed the Petition for Review on Certiorari raising a sole question of law.

• The Holographic Will: On December 24, 1968, Natividad K. Kalaw executed a holographic will. As first written, it named her sister, petitioner Rosa K. Kalaw, as her sole heir.
• The Alterations: The testatrix later altered the will by crossing out "sister Rosa K. Kalaw" and inserting "brother Gregorio Kalaw" as the sole heir and "sole executrix." The alteration substituting the heir was not even initialed; the alteration substituting the executrix was initialed, but neither carried her full signature.
• Probate Proceedings: On September 1, 1971, private respondent Gregorio K. Kalaw filed a petition for probate, claiming to be the sole heir based on the altered will.
• Opposition: Rosa opposed probate, invoking Art. 814 of the Civil Code. She argued the unauthenticated alterations were void, so the will should be probated as first written, naming her as sole heir.
• NBI Examination: The will was submitted to the NBI, which reported that the handwriting, signature, insertions, and initial were all made by Natividad.
• CFI Ruling: The CFI denied probate, applying Art. 814 and ruling that the insertions/alterations not authenticated by the full signature of the testatrix could not be admitted. The CFI rejected Gregorio's argument that Rosa was estopped from invoking Art. 814 because she agreed to the NBI examination.

• The holographic will contained alterations, corrections, and insertions without the proper authentication by the full signature of the testatrix as mandated by Art. 814 of the Civil Code.
• The unauthenticated alterations should be voided, but the holographic will as first written should be given effect and probated, recognizing petitioner Rosa as the sole heir.

• Since the alterations and insertions were made by the testatrix herself, denying probate of the entire holographic will would be contrary to her right of testamentary disposition. (Argued in the Motion for Reconsideration before the CFI).

• Procedural Issues: N/A
• Substantive Issues: Whether the original unaltered text of a holographic will should be probated after subsequent alterations substituting the sole heir are voided for lack of authentication under Art. 814 of the Civil Code.

• Procedural: N/A
• Substantive: No, the original unaltered text cannot be probated. Ordinarily, unauthenticated alterations invalidate only the specific altered words, not the entire will (following Velasco v. Lopez). However, this case presents an exception. Because the holographic will had only one substantial provision, and that very provision was the one altered without proper authentication, voiding the alteration leaves nothing valid in the will. To give efficacy to the original text would disregard the testatrix's evident change of mind. Since the change of mind cannot be given effect either (due to lack of authentication), the testatrix's real intention cannot be determined with certitude. The entire will is therefore voided.

• Effect of unauthenticated alterations in a holographic will (General Rule) — Under Art. 814, insertions, cancellations, erasures, or alterations must be authenticated by the testator's full signature. Failure to do so invalidates only the specific altered words, not the entire will, provided the essence and validity of the will itself remain unaffected.
• Effect of unauthenticated alterations (Exception) — If the unauthenticated alteration affects the only substantial provision of the will (e.g., substituting the sole heir), the entire will is voided because nothing valid remains. The original text cannot be probated because doing so would ignore the testator's change of mind, and the alteration cannot be probated due to lack of authentication.

• Article 814, Civil Code — States that in case of any insertion, cancellation, erasure, or alteration in a holographic will, the testator must authenticate the same by his full signature. Applied strictly by the SC: because the alteration substituting the sole heir lacked the testatrix's full signature, the alteration is void. Since it was the only substantial provision, the entire will is void.
