Informal alteration to a will

How easy is it to just make a handwritten alteration to a will saying “Alteration to my will”, then date the will but not arrange for any witnessing of the alteration and then staple the handwriting to an earlier copy of the will.

This was clearly the testator’s intention as to how he would make a gift of a painting to his ex wife in the 2016 case of Fraser v Melrose. The court considered that this handwritten alteration was to be considered as an informal alteration to the will.

Warning: it is always preferable to seek legal advice as to any intended alteration as the court may not necessarily adopt this case and determine a contrary outcome.
