Video Wills: Are these the future?
The Supreme Court of NSW considered the possibility of an informal "video" Will Re estate of Wai Fun CHAN, deceased  NSWESC 1107.
I think they are rubbish as a cardinal document and should only ever be used as a supplement to a properly prepared and drafted Will by a lawyer.
A video will can express final words of love and joy (or even hate and disgust) towards family and friends. A video is not a replacement for a Will which has deep roots in law and should not be tampered with.
Here’s more on this case from the Sydney Morning Herald where you can see the issues caused by the video Will’s legal validity.
