Yes, if you choose to make a private will in Switzerland without a notary public, it is strictly mandatory that the entire document is written by hand (Art. 505 ZGB). A will that is typed on a computer, printed, or written on a typewriter and merely signed by hand is null and void under Swiss law and will be declared invalid if challenged in court.

⚠️ Why Swiss Law Demands Full Handwriting:
Swiss courts rely on handwriting analysis to verify authenticity and ensure the testator acted freely without coercion or digital forgery.
