Co-Ownership Structures: Helping Clients Make Informed Decisions

Rising property prices in New Zealand have made co-ownership arrangements increasingly attractive for buyers who want to enter the market sooner than they could do so alone. Whether it is two friends purchasing together, family members pooling resources, or a formal equity-sharing arrangement with a third party, co-ownership comes with both genuine opportunities and real complexity. Clients who rush into a co-ownership arrangement without fully understanding the financial and legal implications can find themselves in difficult situations that are hard to unwind. At Chaperone, we work with brokers who regularly guide clients through these conversations, and we believe the most important thing a broker can do is ensure that every party understands the full picture before committing.

The Main Types of Co-Ownership

In New Zealand, co-owned property is typically held as either joint tenancy or tenancy in common. Under joint tenancy, both owners hold the property equally and without defined shares, and if one owner dies, their interest passes automatically to the surviving owner. Under tenancy in common, each owner holds a specified share of the property, which they can leave to whoever they choose in their will and which they can potentially sell independently. For friends or non-related parties purchasing together, tenancy in common with clearly defined shares is generally more appropriate, and clients should discuss this with their solicitor before settlement.

How Lenders Assess Co-Ownership Applications

When two or more people apply for a mortgage together, lenders typically assess all parties as joint borrowers, meaning each person is fully liable for the entire debt, not just their share. This has important implications if one party defaults, faces financial hardship, or wishes to exit the arrangement. Lenders will assess the combined income and liabilities of all applicants, which can be advantageous from a serviceability perspective but also means that one party's poor credit history or high existing debt can affect the entire application. It is worth walking clients through these mechanics early so they understand what they are committing to as co-borrowers.

Property Sharing Agreements

A co-ownership arrangement without a written agreement is an arrangement waiting for problems. A properly drafted property sharing agreement should cover each party's share, their respective contributions to the deposit and ongoing costs, what happens if one party wants to sell or buy out the other, and how decisions about the property will be made. It should also address death, relationship breakdown, or financial hardship. While it may feel unnecessary when everyone is on good terms, a clear agreement protects all parties and is far less expensive than resolving a dispute later without one.

Exit Strategies and Future Flexibility

One of the most important, and often overlooked, aspects of co-ownership is the question of what happens when one party wants to exit. This might happen because one co-owner wants to move, their circumstances change, or the relationship between the parties deteriorates. Without a buyout mechanism agreed in advance, exiting a co-ownership arrangement can be complicated and expensive. If one party cannot afford to buy out the other and neither wants to sell, the situation can become genuinely difficult. Brokers who raise exit strategy as part of the co-ownership conversation are providing advice that can save clients significant difficulty down the track.

Equity Sharing Schemes and Family Contributions

Some clients enter into equity sharing arrangements where a family member or specialist provider contributes part of the deposit in exchange for a share of the property's future value. These arrangements can be genuinely useful for buyers unable to reach the deposit threshold, but they require careful scrutiny. Lenders treat equity sharing structures differently, and some require specific documentation before accepting a co-contributed deposit. Clients benefit from seeking legal and financial advice before committing, and from understanding how returns and costs will be shared when the property is eventually sold or refinanced.

When to Refer to Other Professionals

Co-ownership sits at the intersection of mortgage lending, property law, relationship property law, and tax. Brokers are well placed to explain the lending mechanics and flag the key questions clients need to address, but referring clients to a solicitor and an accountant for the legal and tax dimensions is not just appropriate - it is essential. At Chaperone, we see the best brokers as orchestrators who bring together the right expertise for each situation rather than trying to cover every dimension themselves.

• Explain the difference between joint tenancy and tenancy in common and why it matters
• Make clear that co-borrowers are jointly and severally liable for the full debt, not just their share
• Strongly encourage clients to engage a solicitor to draft a property sharing agreement before settling
• Raise exit strategy and buyout mechanisms as essential conversation topics, not afterthoughts
• Refer clients to solicitors and accountants for the legal and tax dimensions of their co-ownership structure
