Is a handwritten will valid?

Is a hand written will valid—many states recognize holographic wills if material provisions and signature are in the testator's handwriting (requirements vary). About half of states allow them; others require witnesses. ^[1][2] California example Probate Code 6111 sets rules for holographic wills when executor and date requirements are met. Risks Ambiguity, lost pages, and undue influence claims increase with informal wills. Better practice Attested wills with witnesses and notarization (where allowed) reduce contests. ^[1][2]
