Writing Your Own Will in New Zealand

The idea often begins with a sensible question:

Can I write my own will in NZ?

Perhaps your estate seems straightforward. You have a home, some savings, a vehicle, and a few personal possessions. You know whom you want to inherit, and you would rather avoid turning a simple plan into an expensive legal exercise.

In New Zealand, you are generally allowed to prepare your own will. A lawyer is not required merely to make the document legally possible. The real challenge is not gaining permission to write it. The challenge is creating a will that is clear, complete, properly signed, and suitable for the way your assets and family relationships actually work.

A homemade will can succeed.

It can also contain a mistake nobody discovers until after your death, when you are no longer available to explain what you meant.

The safest way to approach a self-written will is to understand both sides of the decision: what you can reasonably do yourself and which risks are difficult to recognise without personalised advice.

Is It Legal to Write Your Own Will in NZ?

Yes. New Zealand law does not generally require a lawyer or professional will writer to prepare your will.

Most adults aged 18 or older can make one, provided they have the required testamentary capacity and act voluntarily. Limited exceptions also allow some people under 18 to make wills in particular circumstances. citeturn350733search0turn350733search3

The document must ordinarily be in writing and completed using the required signing and witnessing procedure.

That means a will does not become valid simply because:

• You wrote it by hand
• You titled it “Last Will and Testament”
• Your family knows what you want
• You saved it on your computer
• You signed it privately
• You told your executor where it is
• It contains formal legal language

The wording and execution must work together.

A plain document signed correctly may be more dependable than an impressive-looking document completed incorrectly.

Why People Choose to Write Their Own Wills

Cost is an obvious reason, but it is not the only one.

Some people prefer a homemade will because they:

• Have relatively few assets
• Want a straightforward distribution
• Feel comfortable preparing documents
• Prefer privacy
• Want to complete the task immediately
• Have no children or complicated dependants
• Believe their family is unlikely to disagree
• Want to create an initial plan before seeking advice

For a genuinely simple estate, self-preparation may feel manageable.

Imagine Anna, a fictional single New Zealander with no children. She owns a vehicle, ordinary household possessions, and money in two bank accounts. She wants her brother to act as executor and her two nieces to divide the estate equally.

That plan may be suitable for a relatively straightforward will, provided Anna includes replacement arrangements and follows the signing rules.

Now imagine a second person who describes their wishes just as simply:

“Everything to my partner, then to my children.”

Behind that sentence may be jointly owned property, children from an earlier relationship, a family trust, business assets, family loans, and competing relationship-property rights.

The words are simple. The estate is not.

Start With an Estate Inventory

Before writing any clauses, identify what you own and what you owe.

Your asset list may include:

• Homes and land
• Bank accounts
• Term deposits
• Investments
• Vehicles
• Business interests
• Company shares
• Valuable personal possessions
• Money owed to you
• Intellectual property
• Digital assets with financial value
• Insurance payable to your estate

Your liability list may include:

• Mortgages
• Personal loans
• Business debts
• Credit balances
• Tax liabilities
• Guarantees
• Money owed to family members

You do not necessarily need to list every asset and account number in the will itself. The inventory helps you understand what the estate plan must address.

It also forces you to ask a more important question:

Do I legally own this asset?

Property held by trustees generally belongs to the trust. Some jointly owned property may pass directly to the surviving owner. The surviving partner also has a prior claim to their own share of relationship property, which cannot simply be given away through your will. citeturn350733search21

A self-written will cannot overcome incorrect assumptions about ownership.

Decide Who Will Be Your Executor

The executor is the person responsible for administering your estate.

Their work may include:

• Finding and securing assets
• Applying for probate
• Contacting financial institutions
• Paying debts and estate expenses
• Completing tax obligations
• Maintaining or selling property
• Responding to claims
• Preparing estate accounts
• Distributing inheritances

Where probate is required, the executor named in the will is the person or organisation that applies for it. citeturn350733search6

Choose someone who is honest, organised, emotionally steady, and willing to perform the role.

Do not appoint someone solely because they are:

• Your eldest child
• Your closest relative
• The person who lives nearest
• The beneficiary receiving the largest share
• Someone you are afraid of offending

Ask the person before naming them.

You should also name at least one replacement executor. Your first choice might die before you, lose capacity, move overseas, become unsuitable, or refuse to act.

Identify Your Beneficiaries Clearly

A beneficiary is a person or organisation receiving something from your estate.

Use full names where appropriate and make relationships clear.

Avoid vague descriptions such as:

• My favourite nephew
• My closest friend
• The daughter who looks after me
• The grandchildren who visit
• Whoever needs the money most

These phrases may feel meaningful while you are alive, but the executor needs an objective way to identify the recipient.

You should also consider what happens if a beneficiary dies before you.

Suppose you leave the estate equally to your two children. One dies first, leaving children of their own.

Should that deceased child’s share pass to:

• Their children?
• Your surviving child?
• Another beneficiary?
• The residue of the estate?

Do not leave this unanswered.

A good will provides substitutes rather than relying on everyone surviving in the expected order.

Use Specific Gifts Carefully

You may want to leave particular possessions or amounts to named people.

Examples include:

• A vehicle to a child
• Jewellery to a grandchild
• A fixed sum to a friend
• Artwork to a sibling
• Tools to a nephew
• A family heirloom to a cousin

Describe the gift clearly enough for the executor to identify it.

“My special ring” may be unclear if you own several meaningful rings.

You should also think about what happens if you no longer own the item at death.

If you leave a particular vehicle to someone and later sell it, the beneficiary does not necessarily receive your replacement vehicle or the sale proceeds.

The more specific gifts you include, the more often the will may need reviewing.

Do Not Forget the Residue

The residue is everything left after debts, estate expenses, taxes, and specific gifts have been dealt with.

For many estates, it includes most of the value.

A proper residue clause should state:

• Who receives the remainder
• What proportion each person receives
• What happens if a beneficiary dies first
• Who receives the estate if all primary beneficiaries are gone

Without an effective residue clause, part of the estate may be distributed under intestacy law rather than under your personal instructions.

For example, you might leave your car to your brother and jewellery to your daughter but say nothing about your home, savings, or investments.

The will has not distributed the complete estate.

The residue clause is not an optional final paragraph. It is often the clause doing the most important work.

Think Carefully About Children

A parent may use a will to record a preference for who should act as testamentary guardian for a minor child.

That choice is important, but it does not necessarily settle every issue concerning day-to-day care or override all rights of surviving guardians.

The will should also address the child’s inheritance.

Questions include:

• Who will manage the money?
• At what age will the child receive control?
• Can funds be used earlier for education?
• Can trustees pay for healthcare or accommodation?
• Who acts if the first trustee cannot?
• What happens if the child dies before receiving the inheritance?

A basic clause may be enough for a modest estate. More substantial inheritances or beneficiaries with additional needs may require specialised trust drafting.

The person caring for the child does not necessarily need to be the person managing the child’s inheritance.

Include Stepchildren Deliberately

If you want a stepchild to inherit, say so clearly.

Do not assume a reference to “my children” will always include a stepchild merely because you consider them part of your immediate family.

The same caution can apply to other family relationships that may not fit standard legal definitions.

A homemade will often uses ordinary family language without recognising that the executor must apply the legal meaning of the finished document.

Identify intended beneficiaries rather than assuming the family will interpret your words generously.

Avoid Copying Clauses You Do Not Understand

The internet contains many will clauses that look authoritative.

Copying them can create serious problems when they were:

• Written for another country
• Designed for a different family structure
• Taken from an outdated law
• Intended to work with another clause you did not copy
• Written for trust property
• Designed for a business estate
• Unsuitable for your ownership arrangements

Legal language can appear universal while performing a very specific function.

Do not insert a clause merely because it sounds protective or formal.

If you cannot explain in ordinary language what a clause does, do not assume you should sign it.

Follow the Signing Rules Precisely

This is where many homemade wills fail.

Under the ordinary New Zealand process, the will-maker must sign the will or acknowledge an existing signature while two witnesses are together in the will-maker’s presence. Each witness must then sign while the will-maker remains present. citeturn350733search0turn350733search17

The safest sequence is:

1. Print or prepare the complete final will.
2. Gather the will-maker and two witnesses together.
3. Confirm that all pages are present.
4. Have the will-maker sign while both witnesses watch.
5. Have the first witness sign while the will-maker remains present.
6. Have the second witness sign while the will-maker remains present.
7. Complete witness names, addresses, occupations, and dates.
8. Check everything before anyone leaves.

Do not:

• Sign alone and collect witnesses later
• Ask the witnesses to sign on different days
• Send a signature page to someone else
• Leave the room while the witnesses sign
• Add information after everyone has finished
• Replace an incorrect page after signing

A court may sometimes validate a document that does not comply with every ordinary formality, but this can involve a complex High Court process. It is not a dependable alternative to signing correctly. citeturn350733search15

Choose Independent Witnesses

Do not use a beneficiary as a witness.

You should also avoid using the spouse, civil union partner, or de facto partner of a beneficiary.

The whole will may not automatically fail, but the gift to the witness or connected partner can be affected.

An executor can legally witness a will, but executors are frequently beneficiaries. In that situation, an independent witness should be used instead.

Good witnesses are adults who:

• Receive nothing under the will
• Are not partners of beneficiaries
• Can observe the signing
• Understand the role of witnessing
• Can provide clear identifying details
• Are likely to be traceable later

The witnesses do not need to read the will. Their role is to observe the execution process.

Do Not Make Handwritten Changes Later

After the will has been signed, leave it alone.

Do not:

• Cross out a beneficiary
• Write in a new executor
• Change a percentage
• Replace a page
• Use correction fluid
• Add instructions in the margin
• Attach an unsigned note
• Remove staples

Changes generally need to be made through a new properly executed will or a valid codicil. A codicil is a supplementary will document and must be signed and witnessed with the same care as the original. citeturn350733search14

Where several changes are required, one clean replacement will is often easier to interpret than several amendments.

Do not destroy your existing will before the replacement has been completed correctly.

Store the Original Where It Can Be Found

A homemade will is particularly vulnerable to disappearing because no professional adviser may have a record of it.

Store the original somewhere:

• Secure
• Dry
• Protected from fire and water
• Unlikely to be discarded
• Free from unauthorised changes
• Known to the executor
• Accessible after death

Keep a clearly labelled copy, but do not assume a scan automatically replaces the original.

Tell your executor that the document exists and where it is stored.

A secret location known only to you defeats the purpose of the will.

When Writing Your Own Will May Be Reasonable

A homemade will may be more manageable where:

• Your estate is modest and straightforward
• Your assets are located in New Zealand
• You understand how your property is owned
• Your beneficiaries are adults
• Your family relationships are uncomplicated
• You intend a conventional distribution
• You have no business or farm
• You have no significant trust involvement
• You are not excluding close family
• There is little realistic risk of a dispute
• No beneficiary needs a specialised trust

Even in these circumstances, having the completed document checked may identify issues you did not recognise.

Community legal guidance confirms that people can make their own wills, while warning that homemade wills are more likely to create probate difficulties or become the subject of challenges. citeturn350733search10

When a Homemade Will Becomes Risky

Personal advice is especially valuable if you:

• Have a blended family
• Are separated but not divorced
• Have entered a new de facto relationship
• Want to exclude a close relative
• Want to divide the estate unequally
• Own a business or farm
• Have overseas assets
• Are involved in a family trust
• Have significant loans to relatives
• Support a vulnerable beneficiary
• Expect disagreement between beneficiaries
• Have concerns about capacity or pressure
• Want to create a long-term trust
• Have promised property in return for care or work

These situations are not difficult because the will needs more impressive language.

They are difficult because several legal rights, ownership structures, and human relationships may compete.

A generic document cannot always identify those conflicts.

The True Cost of a Homemade Will

Writing your own will may save money during your lifetime.

The question is whether it saves the estate money later.

An unclear or defective will may require:

• Additional probate evidence
• Affidavits from witnesses
• Court validation
• Interpretation of uncertain clauses
• Investigation of ownership
• Negotiation between beneficiaries
• Advice about failed gifts
• Litigation
• Delayed distribution

The person who made the mistake does not pay those costs personally. The estate and family deal with them after death.

This does not mean a homemade will is automatically irresponsible. It means the decision should be based on the complexity of your circumstances rather than the apparent simplicity of the finished document.

Can You Write Your Own Will in NZ?

Yes.

You are permitted to take control of the process, record your own wishes, and prepare your own document.

But permission is not the same as protection.

A reliable self-written will must identify the estate accurately, appoint suitable executors, name beneficiaries clearly, include substitutes, distribute the residue, address children appropriately, follow the witness rules exactly, and remain accessible after death.

The hardest mistakes are often invisible to the person making them.

A clause may sound clear but carry a different legal meaning. An asset may feel personally owned while belonging to a trust or surviving joint owner. A family relationship may seem obvious while falling outside the wording used.

Writing your own will can work when your circumstances are genuinely straightforward and you approach the task with care.

The goal is not merely to leave behind a signed document.

It is to leave behind instructions that your executor can confidently follow.

Frequently Asked Questions

1. Can I legally write my own will in New Zealand?

Yes. You do not generally need a lawyer to prepare your will. The finished document must still satisfy New Zealand’s legal requirements and be suitable for your circumstances.

2. Does a homemade will need two witnesses?

Yes. Under the ordinary process, two witnesses must be together when you sign or acknowledge your signature. Each witness must then sign while you remain present.

3. Can I handwrite my own will?

A handwritten will can be valid if it is clear and properly executed. Handwriting the document does not remove the need for appropriate witnesses or complete instructions.

4. Can my family witness my homemade will?

A family member may sometimes act as a witness, but nobody receiving a benefit should witness. The spouse or partner of a beneficiary should also be avoided. Independent witnesses are safer.

5. Can I use a will template from another country?

This is risky. Overseas templates may rely on different succession laws, signing rules, terminology, tax systems, or court procedures. Use wording designed for New Zealand circumstances.

6. What clauses should my homemade will include?

A basic will commonly identifies you, revokes earlier wills, appoints an executor and replacement, makes any specific gifts, distributes the residue, names substitutes, and includes suitable arrangements for children where required.

7. What happens if I make a mistake?

The effect depends on the error. A gift may fail, a clause may become uncertain, or the High Court may need to determine whether the document can be accepted. Correcting the problem during your lifetime is far easier.

8. When should I avoid writing my own will?

Personal assistance is strongly advisable for blended families, overseas property, businesses, trusts, unequal gifts, excluded relatives, vulnerable beneficiaries, disputed relationships, capacity concerns, or any estate likely to attract disagreement.
