A will cannot be invalidated on the basis of minor name variations or the use of shortened versions of names where the identity of the testator can be established through corroborating documentary evidence including consistent identity numbers, signatures, dates of birth, and references to known family members and property. To successfully challenge the validity of a will, a party must demonstrate non-compliance with the formalities required by section 8 of the Wills Act, Chapter 6:06. Mere discrepancies in the use of full names versus shortened names or alternative family surnames, without more, do not render a will invalid where the testator's identity is established on a balance of probabilities.
