What Happens to Jointly Owned Shares on Death? A Guide for NZ Co-Owners

Imagine you and your partner bought a house together. You split the mortgage, you split the repairs, and you both signed the title. Then, one of you passes away unexpectedly. Who owns the property now? Does it go to the deceased’s children from a previous relationship? Or does the surviving partner automatically keep everything?

This is not just a hypothetical nightmare; it is a legal reality that thousands of New Zealanders face every year. The answer depends entirely on how you held the title when you were alive. In New Zealand, there are two main ways to hold property jointly: as Joint Tenants or a form of ownership where the last surviving owner automatically inherits the share of those who have died. or as Tenants in Common or a form of ownership where each person holds a distinct, separate share that can be passed on through their will.

Getting this wrong can lead to family feuds, costly legal battles, and even the forced sale of the home you thought was yours. Let’s break down exactly what happens to jointly owned shares on death, so you can protect your assets and your relationships.

The Golden Rule: Right of Survivorship

If you are a Joint Tenant, the process is surprisingly simple-and often final. This structure relies on a legal concept called the "right of survivorship." When one joint tenant dies, their interest in the property does not go into their estate. It doesn’t go to their spouse, their kids, or their bank. Instead, it instantly transfers to the surviving joint tenant(s).

Think of it like a bucket with two handles. If one person lets go, the other person doesn’t lose half the water; they just take over holding the whole bucket. The deceased’s share simply vanishes from their side and merges with the survivor’s.

This means:

• The property bypasses the probate process entirely.
• The deceased’s will has no power over this specific asset.
• The surviving owner becomes the sole legal owner immediately upon death.

This setup is incredibly popular among married couples or de facto partners who want to ensure the surviving partner isn’t left homeless or burdened with legal hurdles. However, it comes with a major risk if your personal circumstances change.

When Shares Are Held as Tenants in Common

Now, let’s look at the other side of the coin: Tenants in Common. This arrangement is fundamentally different. Here, you and your co-owner do not own the property as a single, indivisible unit. Instead, you each own a specific percentage-perhaps 50/50, or maybe 70/30 if one of you contributed more to the deposit.

Because your share is distinct, it is treated as part of your personal estate when you die. This triggers a completely different set of events.

1. The Will Takes Effect: Your share goes to whoever you named in your will. If you didn’t leave a will, it goes according to the Succession Act (usually to your closest relatives).
2. Probate is Required: The executor of the estate must apply for a grant of probate. This is a court order confirming the will is valid. This process can take months in New Zealand, depending on the complexity of the estate.
3. Transfer of Title: Once probate is granted, the executor can transfer your share to the beneficiary. At this point, the beneficiary becomes a new co-owner with the surviving original owner.

This scenario creates a complex dynamic. Imagine you bought a house with your sibling as tenants in common. You pass away, and your share goes to your child. Now, your sibling owns 50% of the house, and your child owns the other 50%. They may not get along. They may have different financial goals. This is where disputes often arise.

The Hidden Danger: Family Protection Claims

New Zealand law has a unique twist that catches many people off guard. Even if you hold property as Joint Tenants and the survivor automatically gets the house, the deceased’s family might still come knocking.

Under the Family Protection Act 1980 or legislation allowing close family members to claim reasonable provision from a deceased's estate if they feel neglected., certain family members (spouses, civil union partners, and dependent children) can make a claim against the estate within two years of death.

Here is the tricky part: Courts in New Zealand have ruled that a share transferred by "right of survivorship" is still considered part of the deceased’s "net estate" for the purposes of these claims. If the deceased’s children believe they were unfairly cut out of the inheritance because the house went straight to the surviving partner, they can sue.

If the court agrees, it can order the surviving partner to pay compensation to the children. Often, the only way to raise that cash is to sell the house. So, while Joint Tenancy protects the survivor from immediate loss of title, it does not necessarily protect them from a future lawsuit that could force a sale.

How to Protect Yourself and Your Co-Owners

You don’t have to guess what will happen. You can control the outcome before anything goes wrong. Here are three practical steps to take today.

1. Check Your Land Title

Go to the Land Information New Zealand (LINZ) or the government agency responsible for land titles and mapping in New Zealand. website. You can buy a copy of your title for a small fee. Look at the "Proprietors" section. It will explicitly state whether you are registered as "Joint Tenants" or "Tenants in Common." If it says nothing, the default assumption in New Zealand for individuals is usually Joint Tenancy, but checking is free peace of mind.

2. Update Your Will

If you are Tenants in Common, your will must be clear. Don’t just say "my share of the house." Specify percentages. More importantly, talk to your co-owner. Do they want to buy out your share if you die? Do they want to live with your heir? Put this agreement in writing. A "Co-ownership Agreement" can stipulate that if one party dies, the survivor has the first right to buy the deceased’s share at a pre-agreed valuation method.

3. Consider a Trust

For high-value properties or complex family situations, placing the property in a trust can offer robust protection. A trust separates legal ownership from beneficial ownership. While setting up a trust costs money upfront, it can prevent Family Protection claims and ensure your wishes are followed without court interference. Many Kiwis use trusts specifically to manage shared assets across generations.

What If There Is No Will?

If you die without a will (intestate), the rules become even stricter. For Tenants in Common, your share will be distributed according to the Succession Act 1965. Typically, this means:

• If you had a spouse/partner and children: The spouse gets the household effects and a statutory sum, while the rest is split between the spouse and children.
• If you had no spouse but had children: The children inherit everything equally.

In a Joint Tenancy, the lack of a will doesn’t change the immediate transfer to the survivor, but it leaves the survivor vulnerable to claims from the deceased’s next-of-kin under the Family Protection Act, as mentioned earlier.

Common Mistakes to Avoid

I see the same errors repeated in almost every estate dispute I analyze. Avoid these pitfalls:

• Assuming "Joint" Means Equal Contribution: You can be Joint Tenants even if one person paid 90% of the deposit. Legally, you own it equally. If you want your larger contribution protected, you should be Tenants in Common with a written agreement.
• Ignoring De Facto Rights: In New Zealand, de facto partners have similar rights to married couples after three years of living together (or one year with a child). They can also make Family Protection claims.
• Failing to Notify Banks: If the property has a mortgage, the bank needs to know about the death. In a Joint Tenancy, the survivor takes on the full debt. In Tenancy in Common, the estate is liable for its share of the debt.

Next Steps for Shared Owners

If you currently own property with someone else, do not wait for a crisis to reveal your status. Sit down with your co-owner this week. Ask them: "If something happened to me, what would you want to happen to the house?" Write down the answer. Then, check your title. If your legal structure doesn’t match your verbal agreement, contact a solicitor to change it. Changing from Joint Tenants to Tenants in Common (or vice versa) is a relatively simple paperwork exercise with LINZ, provided you both agree.

Protecting your home is about more than just bricks and mortar. It’s about protecting the people you love from uncertainty, conflict, and financial ruin. By understanding the difference between Joint Tenancy and Tenancy in Common, you take back control of your legacy.
