If the amount of such advancement exceeds the share of the heir receiving the same, he must be excluded from any further portion in the division and distribution of the estate, but he must not be required to refund any part of such advancement; and if the amount so received is less than his share, he is entitled to so much more as will give him his full share of the estate of the decedent.
