What if the whole family dies together?

Backup beneficiaries stop your estate defaulting to strangers.

It's rare, but it happens — a car accident, a house fire, a shared holiday gone wrong. If every person you'd normally leave your estate to (your partner and your children) dies alongside you, what happens to everything you own?

Without a clear Will

  • Without named backup beneficiaries, a 'failure of gift' occurs — the law has to work out who inherits, and the answer is often not who you'd choose.
  • If you die intestate as well, the Administration Act 1969's fixed formula reaches further out — to your parents, then siblings, then more distant relatives — in a strict legal order that ignores relationships, needs or your wishes.
  • Even with a Will, if it only names your immediate family as beneficiaries and doesn't say what happens if they're gone too, the gifts to them simply fail and that part of the estate falls back to intestacy rules.
  • Sorting this out can take much longer and cost far more in legal fees, drawn out over multiple layers of extended family.

With a Will

  • You name contingent (backup) beneficiaries — for example, siblings, close friends, godparents or a charity — so there's always a clear next choice.
  • You can be as specific as you like: different backups for different gifts, or one overall backup for 'everything else'.
  • You avoid the estate defaulting to distant relatives you may barely know, or the Crown if truly nobody can be found.
  • Charities are a common backup choice for people without close family — leaving a legacy on your own terms rather than by default.

Practical guidance for NZ

  • Always name at least one layer of backup beneficiaries, even if it feels unlikely you'll ever need them.
  • A simple catch-all clause — 'if none of the above survive me, my estate goes to [person/charity]' — closes the gap cheaply.
  • Revisit your backups occasionally; people's circumstances (and relationships) change.
  • If truly no one can be found to inherit, the estate ultimately passes to the Crown ('bona vacantia') — a fate that's easy to avoid with one extra clause.

Worth getting advice on

For larger or more complex estates, get advice on structuring backup gifts so they're clear and don't unintentionally trigger extra tax or trust complications.
