Succession takes place by law or by last will provision. When it comes to disposition of last will, it is said that it is a testamentary succession, carried out by will or codicil. The testator who has the necessary heirs must reserve half of his assets, called a legitimate part. The other half, called the available part, can be freely assigned to anyone who the tester wants. Consequently, if there are no necessary heirs, all assets can be freely disposed of by the tester. The testator may regulate the distribution of his assets, including non-equity issues, in his will; he can stipulate what assets his heirs will receive, always respecting the minimum that each one has the right to. In order for testamentary succession to take place, it is necessary for the testator to be able to dispose of assets, declare will in the manner required by law and observe the limits of the power of testing. The accompaniment of a lawyer guarantees the desired testamentary succession.
