Can a person bequeath any property to any person at his or her discretion and then revoke or amend the will, deprive the heirs by law of succession and determine the portion of the heirs in the succession?

Yes, a citizen has the right, at his or her discretion, to bequeath any property to any person, to determine the portion of the heirs in the succession in any manner, to deprive the heirs by law of succession, to revoke, amend, or supplement the composed will. Moreover, he or she is not obliged to inform anybody on making, amending or revoking a will.

This right of the citizen is restricted only by the rules on compulsory portion of a succession. A compulsory portion is considered as the right of an heir to inherit, regardless of the content of the will, at least half of the portion which would have been allotted to him or her in case of succession by law. At the time of opening the succession, minor children, as well as children, the spouse, and parents of a testator who have been declared as disabled or having no active legal capacity as prescribed by law or have attained the age of 60, have the right to compulsory portion.
