Two Ways to Own Property—And Why It Matters More Than You Think

When two or more people buy property together in New Zealand, they must decide how the property will be legally owned. The two main options are joint tenancy and tenancy in common.

While these terms might seem like technical property law concepts, they can have major consequences for couples, families, and relationship property disputes. In family law matters — including separation, estate planning, and blended families — the way a property is owned can significantly affect what happens to the home or investment property.

Here we explain the difference between joint tenants and tenants in common in New Zealand, and why the choice matters for couples and families.

What Is Joint Tenancy?

A joint tenancy means that two or more people own the property together as a single legal unit. Each owner has an equal interest in the entire property.

The key feature of joint tenancy is called the right of survivorship. This means that when one owner dies, their interest in the property automatically transfers to the surviving owner or owners. For example:

• A couple purchases their home as joint tenants.

• If one partner dies, the surviving partner automatically becomes the sole owner of the property.

• The deceased partner’s share does not form part of their estate and cannot be distributed under their will.

Because of this automatic transfer, joint tenancy is very common for married couples or long-term partners buying a family home.

However, joint tenancy also means that ownership shares must be equal. Even if one partner contributed more money to the purchase, the law treats both parties as owning the property equally.

What Is Tenancy in Common?

A tenancy in common is different because each owner holds a separate and identifiable share of the property. Those shares can be equal or unequal. For example:

• 50% / 50%

• 70% / 30%

• or any other agreed proportion.

Unlike joint tenancy, there is no right of survivorship. If one owner dies, their share becomes part of their estate and is distributed according to their will or under New Zealand intestacy rules. For example:

• A couple owns a home as tenants in common.

• One partner dies.

• Their share passes to the beneficiaries named in their will (such as children), rather than automatically transferring to the surviving partner.

This structure allows people to retain control over who inherits their share of the property.

Why This Matters in New Zealand Family Law

Property ownership structures can become especially important in relationship property situations.

Under the Property (Relationships) Act 1976, relationship property is generally divided equally when couples separate, regardless of whose name is on the title. However, the way a property is owned can still have practical and legal consequences. For example:

• It may affect estate planning after separation

• It can influence how property is structured in second relationships

• It may impact how assets are managed during a relationship

Many couples also reconsider property ownership when they enter a new relationship or purchase property after separation.

Joint Tenancy and Relationship Breakdown

Joint tenancy can sometimes become problematic when a relationship ends.

Because joint tenants have the right of survivorship, if one partner dies before the property ownership is changed, the entire property could automatically pass to the former partner. For this reason, separating couples often sever the joint tenancy as part of their separation arrangements.

Severing the joint tenancy converts ownership into a tenancy in common, allowing each person’s share to be dealt with separately. This can be an important step in ensuring that assets are distributed according to each person’s wishes, particularly where there are children involved. You can learn more in this recent blog.

Tenancy in Common and Blended Families

Tenancy in common is often preferred where people want greater certainty about their property interests. This is particularly common in:

• Second relationships

• Blended families

• Estate planning involving children from previous relationships

For example, a couple in a second relationship may choose to own their home as tenants in common so that:

• Each partner retains a defined share of the property.

• Their share can pass to their own children through their will.

Without this structure, a joint tenancy could result in the entire property automatically transferring to the surviving partner, potentially leaving children without the inheritance their parent intended.

Investment Properties and Unequal Contributions

Tenancy in common is also frequently used when people purchase property together but contribute different amounts to the purchase price. This might occur when:

• Siblings purchase an investment property

• Friends buy property together

• One partner contributes significantly more to the deposit

By recording ownership shares (for example 60/40), tenancy in common allows the ownership structure to reflect each person’s financial contribution.

Choosing the Right Ownership Structure

There is no single ownership structure that is right for everyone.

Joint tenancy is often appropriate where:

• A couple wants the surviving partner to automatically inherit the property

• The property is the couple’s shared family home

• Estate planning is straightforward

Tenancy in common may be more suitable where:

• There are children from previous relationships

• Owners contribute different financial amounts

• People want their share to pass through their will

• The property is an investment or business arrangement

The right option depends on your personal circumstances, family structure, and long-term plans.

Getting Legal Advice

Property ownership structures are sometimes chosen without fully understanding the long-term consequences. For couples, families, and separating partners, the difference between joint tenancy and tenancy in common can affect inheritance, relationship property rights, and asset protection.

If you are buying property with a partner, entering a new relationship, or going through separation, it may be worth seeking legal advice about how your property should be structured.

Careful planning now can help prevent disputes and ensure your property arrangements reflect your intentions.
