It’s important to have an estate plan to ensure that in the event of death – as morbid as it sounds – your estate assets and interests go to the right person(s) in a timely manner and you should review it every five years or earlier for a major family event.
Your superannuation, however, is not an estate asset and therefore isn’t dealt with via your will unless you specifically leave it to your legal personal representative (LPR) – generally the executor of your estate.
