My mother wrote her will entirely by hand and never showed it to anyone before she died. Is it still legally valid?

Three requirements, and no fourth

Article 810 provides: A person may execute a holographic will which must be entirely written, dated, and signed by the hand of the testator himself. It is subject to no other form, and may be made in or out of the Philippines, and need not be witnessed. Read the word entirely strictly. The whole document must be in her hand — a will she dictated to a grandchild and merely signed is not a holographic will, and neither is a printed form she filled in. A date must appear, and her signature must be there. Meet those three and the Code asks for nothing further.

That nobody knew about it is not a defect

The secrecy that worries you is exactly what this form of will is designed to allow. There are no attesting witnesses to inform, no notary to visit, no obligation to deposit the document anywhere or to tell the family it exists. What authenticates a holographic will is the handwriting itself, which is why the law can afford to dispense with witnesses to the signing. A will found in a drawer after the funeral, seen by nobody during her lifetime, is in no weaker a position under Article 810 than one she had announced to everyone.

Valid in form still is not the same as effective

Two further steps stand between the document and the property. Article 838 provides that no will passes real or personal property unless it is proved and allowed in accordance with the Rules of Court, so the will has to be brought to court whatever its form. And Article 811 sets out how a holographic will is proved: at least one witness who knows the handwriting and signature must declare explicitly that both are the testator's, with three required if the will is contested. Nothing in the estate moves on the strength of the paper alone.

Where these wills usually come apart

The vulnerabilities are in the details of the document. Under Article 814, any insertion, cancellation, erasure or alteration must be authenticated by the testator's full signature, so a crossed-out name or an amount written over is a live issue. Under Article 812, dispositions written below the signature must themselves be dated and signed to be valid. And a valid holographic will still cannot impair the legitimes of compulsory heirs. Keep the original untouched, do not annotate or laminate it, and gather people who can testify to her handwriting — samples in her own hand are worth finding now rather than later.
