It is not necessary to have a great legacy to make a will and to provide, in this way, contribute.
Those who decide to make a will may have only a portion of its assets when there are legitimate children (including adopted children and the legitimated), natural or their descendants, the spouse and the ascending legitimate. These are the people related by blood closer links with the testator, that the opening of the succession are entitled to a share of the inheritance called "unavailable or legitimate or reserve."
It is always possible, however, to have the will of a share of its assets (the so-called "available") without prejudicing the rights to the succession of direct relatives.
A will is an act that can be changed or withdrawn at any time. In any case, the holographic will is valid only if it is written in his own hand by the testator, is dated (day, month, year) and is signed (ie it must be signed by those who will at the end of the provisions).
