A will is a legal document in which you specify who will inherit your property after your death, and what the share of each person will be.
A will must be made in one of three forms: a holograph will, a will made in the presence of witnesses, or a notarial will. A will made in any other form has no legal value.
You should re-read your will from time to time to make sure that it still reflects your true intentions, and that it matches your current situation.
