I prepared a will in Winterthur with the local 'Notar' It was quite cheap to do and I got some very good advice. There were actually 2 documents, an 'Ehevertrag' to cover all assets accumulated in the marriage and a will to cover my personal assets. There were a lot of things to consider that I would never have thought about. For example if you own a house you cannot just leave to house to your wife without paying your children off. This seemed crazy to me as a Brit but that's how it is here.
