If your are an expatriate, a 'will' is required because, the laws of the country in which you reside would be different from that of your home country, and when the inevitable (death) occurs (untimely), your property /possessions may be exposed to the discretion of the state laws for the allocation of your property to someone, you may have never wished that they possess your property and be an heir to your assets.
