If the deceased leaves or gives a will that gives a lot of property only to a certain child during his/her lifetime, other families will not have inherited property, which can be a threat to their livelihood, and in some cases, disputes between families often occur.
Our civil law stipulates an legal reserve of inheritance system to protect heirs who have not been inherited at a minimum level.
If other heirs have filed a claim for legal reserve of inheritance because they think that they have not received their portion of inheritance properly, the heir who has been sued must defend appropriately from defendant’s point of view
(lawsuit for invalidation of gift at the sametime)
