General Gifts/Devices

If a person's will includes a general statement about giving away their property, it should be understood to include any additional property that the person may have the power to give away. This additional property will be given away according to the person's wishes unless the will says otherwise.

Device to a child of a recipient

If someone is named in a will to inherit property but dies before the person making the will (the testator), and they have children (or other descendants) who are alive when the testator dies, then the inheritance should go to those children instead. This is unless the will says something different.

if someone dies before or after the person making the will (testator) and they are a brother or sister who has been given property in the will, and they have children who are alive when the testator dies, then the property will go to the child or children instead of being lost. This only applies if the will doesn't say otherwise. If a child was conceived before the testator died but born after they died, they will still be considered alive at the time of the testator's death.
