You ask it, we have it answered!
Can a family member witness a will?
Your will should be witnessed by independent witnesses. The characteristics of an independent witness are:
14 years or older;
Mentally of sound mind and capable of testifying in court, at the time of signing;
Is not specified in the will (for example as executor, or named as a trustee, heir, beneficiary or legatee); and
Is not the spouse of anyone specified in the will (the person drafting the will; or someone named as executor, trustee, heir, legatee, or beneficiary).
Therefore, if your family member is neither specified in the will nor married to anyone specified in the will, then they could witness your will.
