Inheritance Law / Minimum Forced Inheritance Share Right

According to Greek Inheritance Law, it is forbidden for a testator to entirely disinherit his/her offspring, his/her spouse and his/her parents without legal cause and allows so for very specific reasons.
If the reason for disinheriting a heir of the above, does not fall within the specific reasons that the law has set, or if the testator has bequeathed a smaller percentage of what the heir is entitled, then the heir is entitled to the minimum forced inheritance share right, which is set by the Law to 1/2 of the inheritance share that the heir would have, had the deceased died intestate (i.e. leaving no Will).
