Subtraction from inheritance is valid only if the inheritor has indicated the reason for subtraction in his savings related to it.

If the person removed from the inheritance objects, proof of the existence of the specified cause falls to the heir or will creditor who benefits from the removal.

If the existence of the cause cannot be proven or the reason for subtraction is not specified in the savings, the savings are fulfilled outside the hidden share of the heir; however, if the inheritor made this saving due to a clear error that he fell for the reason for subtraction, the subtraction becomes invalid.
