Do I Need a Lawyer to Write a Will in New Zealand?
New Zealand law does not require you to use a lawyer to make a will. What it does require is that the will is signed and witnessed the way the Wills Act 2007 says. This guide sets out what that means and where advice tends to help.
The short answer
No. A will you write yourself, or make with an online will service, can be just as valid as one drafted by a lawyer, provided it meets the signing and witnessing rules of the Wills Act 2007.
That generally means a written will, signed by you in the presence of two witnesses who are present at the same time, and who then sign in your presence. The High Court can declare an informal document valid in some circumstances, but relying on it is expensive and uncertain, so it is not a substitute for signing properly.
A lawyer, Public Trust or a trustee company adds judgement rather than paperwork. Relationship property, family trusts and blended families are the usual reasons people take advice. See also choosing a will service in New Zealand.
What tends to tip the balance
None of these makes a lawyer compulsory. They are the situations where people most often decide the extra cost is worth it.
A partner and relationship property
A surviving spouse or partner may be able to choose a relationship property division instead of what the will gives them, which can change how the estate is shared.
A likely family protection claim
A partner, children and some other family members can apply to court if the will does not make adequate provision for them. Time limits apply.
A family trust
Assets held in a family trust do not pass under your will, so the trust deed and the will usually need to be read together.
A business or farm
Company shares or a family farm usually need a succession plan that sits alongside the will rather than inside it.
Assets overseas
Property in another country may be governed by that country’s succession rules, which can conflict with a New Zealand will.
Straightforward estate, clear wishes
An estate in New Zealand left to a partner or adult children is the case a structured online will most commonly covers well.
What actually decides whether a New Zealand will is valid
It is in writing
A will must be a written document. The High Court can validate an informal document, but that is a costly court application, not a plan.
You sign it
You sign the will, or someone signs it at your direction and in your presence. The signature is what the witnesses must see.
Two witnesses, present together
Two adult witnesses must be present together when you sign and then sign in your presence. A gift to a witness, or to a witness’s partner, generally fails, so choose neutral witnesses.
The Act governs, not the drafter
Validity turns on whether the will meets the Wills Act 2007, not on who prepared it. The route you choose does not, by itself, make a will stronger.
Frequently asked questions
Is a will legal in New Zealand without a lawyer?
Yes. A will made without a lawyer is valid if it meets the Wills Act 2007 requirements on writing, signing and witnessing. If your circumstances are complicated, consider speaking to a qualified professional in New Zealand.
Can Public Trust write my will instead?
Yes. Public Trust and private trustee companies prepare wills, sometimes at a reduced fee where they are appointed executor. Ask what the estate administration fees would be before you decide, as that is where the cost usually sits.
Does getting married cancel my will in New Zealand?
Generally, yes. Marriage or a civil union usually revokes an earlier will unless it was made in contemplation of that marriage or union, so it is worth reviewing your will after either event.
Is a will kit valid in New Zealand?
A will kit can produce a valid will if it is completed, signed and witnessed correctly. Most problems with kits come from unclear wording or witnessing errors rather than the kit itself.
