What Happens to a Property Title When a Co-Owner Dies in New Zealand

What Happens to a Property Title When a Co-Owner Dies

When a co-owner of a property dies in New Zealand, what happens to the title depends entirely on how ownership was structured. Joint tenancy and tenancy in common — the two main forms of co-ownership — produce very different outcomes. Getting this wrong can delay settlement, create unexpected tax questions, or leave surviving owners in legal limbo.

This guide explains exactly what happens to a New Zealand property title when a co-owner dies, what steps to take, and what records you'll need.

Joint Tenancy vs Tenants in Common: The Critical Difference

Joint Tenancy (Most Common for Couples)

Under joint tenancy, all owners hold the property together as a single legal entity. The defining feature is the right of survivorship — when one joint tenant dies, their interest automatically passes to the surviving joint tenant(s). The deceased's share doesn't form part of their estate and can't be left to someone else in a will.

What happens on the title: the deceased's name is removed and the surviving owner(s) remain. The transfer happens by operation of law — automatic in effect, but you still need to register the change.

Tenants in Common (Common for Investors, Family Groups)

Under tenancy in common, each owner holds a distinct share, equal or unequal. There is no right of survivorship. When a tenant in common dies, their share forms part of their estate and passes according to their will, or under the Administration Act 1969 if there's no will.

What happens on the title: the deceased's share is transferred to their beneficiary or executor — a formal transfer process, not a simple name removal.

How to Find Out Which Type You Have

Check the ownership structure on the Record of Title. If you don't have one, order a Record of Title with Diagram ($42.90) — it clearly states whether owners hold as "joint tenants" or "tenants in common" with specified shares. If the title says nothing about shares, it's typically joint tenancy; if it specifies shares (e.g., "as to an undivided 1/2 share"), it's tenants in common.

What to Do When a Joint Tenant Dies

1. Obtain the death certificate from the Department of Internal Affairs — the primary document required to register the change.
2. Complete a transmission application — the surviving owner(s) apply to have the deceased's interest transmitted to them by survivorship.
3. Register the change with the land registration system. Once registered, the title shows only the surviving owner(s).
4. Notify your mortgagee if there's a mortgage on the property — the bank will need to update its records and may require new documentation from the surviving owner.

What to Do When a Tenant in Common Dies

This path is more complex, since the deceased's share doesn't automatically transfer — it goes through their estate.

1. Determine who inherits the share — check the will; if there's no will, the Administration Act 1969 sets out who inherits, typically a spouse or partner first, then children, then parents, then siblings.
2. Obtain probate or letters of administration — the executor (with a will) or administrator (without one) must get this from the High Court before the share can be transferred. This is a formal process that validates the will and authorises the executor to deal with the estate.
3. Transfer the share — once probate is granted, the executor transfers the deceased's share to the named beneficiary via a standard transfer instrument.
4. Register the transfer, updating the Record of Title to show the new owner of the deceased's share.

Common Complications

• An unfamiliar new co-owner — under tenants in common, the deceased can leave their share to anyone. The surviving owner may end up with a co-owner they didn't choose. Options include negotiating a buyout, applying to the court for an order for sale, or partition proceedings in extreme cases.
• No will and multiple beneficiaries — if the deceased died intestate, their share is divided among next of kin, and several people may now need to agree on what happens to the property.
• A disputed estate — a challenge under the Family Protection Act 1955 or the Property (Relationships) Act 1976 can freeze the transfer of the deceased's share until resolved.
• Mortgage complications — the surviving owner remains liable for the full mortgage. If a new co-owner under tenants in common isn't acceptable to the bank, refinancing may be required.

Relationship Property Implications

The Property (Relationships) Act 1976 adds another layer: if the deceased was married or in a de facto relationship (including a same-sex partnership after three years together), their partner may have a claim on the property even if the will leaves the share to someone else. A surviving partner can choose between what the will provides or a claim under the Act, whichever is more favourable — and family home claims can override the will regardless of whose name is on the title. Time limits for these claims are strict, so get specialist legal advice promptly if this is a concern.

Documents You May Need

• Guaranteed Search ($45.90) — often required by banks and lawyers as the authoritative version of the title.
• Historical Title ($42.90) — shows the full ownership history, useful for confirming the original ownership structure and share allocation.
• Instruments ($39.90) — the actual transfer, mortgage, and other registered documents.
• Legal Owner Search ($65.90) — authoritative confirmation of legal ownership if there's any dispute about it.

Practical Checklist

1. Get the death certificate from the Department of Internal Affairs.
2. Order a current Record of Title to confirm the ownership structure and any encumbrances.
3. Determine the ownership type — joint tenancy or tenants in common.
4. If joint tenancy: prepare and lodge a transmission application by survivorship.
5. If tenants in common: locate the will and apply for probate, or letters of administration if there's no will.
6. Notify the mortgagee and update mortgage documents.
7. Register the ownership change.
8. Update insurance to reflect the change in ownership.

Frequently Asked Questions

Can a joint tenant leave their share to someone else in a will?

No. Under joint tenancy, the right of survivorship means the deceased's share automatically passes to the surviving joint tenant(s) by law, and a will cannot override this. The only way to change this outcome is to sever the joint tenancy before death, converting it to tenants in common by registering a notice of severance.

What if the surviving owner can't afford the mortgage alone?

The mortgage doesn't disappear when a co-owner dies — the surviving owner remains responsible for the full repayment. Options include refinancing, selling the property, or negotiating with the bank. Check whether any mortgage protection insurance applies.

How long does the whole process take?

For joint tenancy, registering the transmission typically takes a few weeks once lodged, assuming no complications. For tenants in common, timing depends on how quickly probate is granted and whether the estate is contested — a straightforward probate can still take several weeks to a couple of months, longer if there's a dispute.
