The witnesses on your Will should be independent witnesses. The characteristics of an independent witness are that he/she:
- Is fourteen (14) years or older;
- Is mentally capable of providing testimony in court, at the time of signing;
- Is not specified in the Will (for example as Executor, Trustee, Heir, Legatee or Trustee);
- Is not the spouse of anyone who has been specified in the Will (the Testator/Testatrix, Executor, Trustee, Heir, Legatee or Beneficiary([ies]).
Therefore, if your family member is neither specified in the Will nor is married to anyone specified in the Will, then he/she may act as witness on your Will.
