A holographic will is easy and cheap to draw up. One reason why it is so popular in Switzerland is because it is easy to update. It can be stored either at home or with a cantonal authority.

Besides handwritten and oral (emergency) wills, the law also recognises the notarised variant. This offers advantages that can mostly pay off when circumstances are complicated or an estate is valuable.

In the event of death, the will is often the most important surviving document. In order for it to be valid, it must meet certain formal requirements. Normally, it must be written by hand, as well as dated and signed.
