Demonstrative Legacy consists of a Pecuniary Legacy, i.e. ‘a certain sum of money or a certain quantity of any other commodity,’ payable out of a particular fund or stock, which fund or stock is the primary source out of which the payment is to be made. The advantage of demonstrative legacy is:

• It is not adeemed (adeemed means it cannot take effect ) by the total or partial failure, at the testator’s death.
• It does not subside with the general legacies until after the particular fund is exhausted.

The only difference between a general legacy and a demonstrative legacy is that where a specific property is indicated, out of which the legacy is payable, it becomes a Demonstrative Legacy.
