Short answer. At least three. Article 811 of the Civil Code requires at least one witness to identify the handwriting in an uncontested holographic will, but when the will is contested, the number rises to at least three witnesses who knew the testator's handwriting and can explicitly confirm it.
What the law says
If the will is contested, at least three of such witnesses shall be required.

Two different thresholds: contested and uncontested
Article 811 of the Civil Code draws a clear line between uncontested and contested holographic wills. When the will proceeds to probate without opposition, at least one witness who knows the testator's handwriting and signature must declare that the will and signature are genuine. But once the will is formally contested — as in your case, where your siblings have raised objections — the minimum rises to at least three such witnesses. The higher number reflects the increased scrutiny that a contested will requires.
What the witnesses must be able to say
The witnesses needed under Article 811 are not character witnesses or people who simply knew your mother. They must be people who knew the handwriting and signature of the testator and can make an explicit declaration that the will and signature are in the testator's own handwriting. Familiarity with the handwriting is the qualification — someone who regularly received handwritten notes or letters from your mother, who saw her sign documents, or who has any other basis for recognising her specific writing style qualifies. Vague impressions are not enough.
What happens if three witnesses cannot be found
Article 811 provides a fallback for situations where no competent witnesses are available. When the court deems it necessary and no such witness can be produced, expert testimony may be resorted to. A handwriting expert can examine the document and compare it against authenticated samples of the testator's writing. Expert testimony does not replace the witness requirement when witnesses are available — it fills in only when they cannot be found. In practice, both witnesses and experts may appear in a contested case.
Building your case for probate
With your siblings contesting the will, you need to identify at least three people who can testify credibly that the handwriting and signature are your mother's. Think about people who corresponded with her in writing, people who witnessed her write or sign documents over the years, former colleagues, or close friends who received handwritten communications from her. You should also preserve any original letters, notes, or signed documents in your mother's handwriting that can serve as comparison materials. A lawyer handling the probate can guide you on how to present this evidence effectively before the court.
