Contesting a will in New Zealand: understanding the process
28 September 2025

When someone passes away, their will is meant to provide clear instructions about how their estate should be managed and distributed. For most families, it offers a sense of direction during a time of grief. But sometimes, questions arise, and a will may be contested.

 

Contesting a will isn’t common, but when it does happen, it can be emotionally and legally complex. At Willis Legal, we’re here to help you understand what’s involved, and to support you through the process with care, clarity, and professionalism.

 

Why might a will be contested?

 

A will can only be challenged on specific legal grounds. Examples include:


  • Family Protection Act claims - where close family members feel they haven’t been properly provided for in the will.
  • Property (Relationships) Act claims - where a surviving partner may be entitled to a share of relationship property.
  • Concerns about validity - for example, if the will wasn’t signed or witnessed correctly, or if the person lacked mental capacity when they made it.
  • Undue influence - where someone may have unfairly pressured the will-maker.

 

It’s important to note that not everyone can contest a will. The law limits this right to certain people, usually spouses, children, or dependents. If you’re unsure whether you’re eligible to make a claim, seeking early legal advice is key.

 

What does the process involve?

 

If someone believes they have grounds to contest a will, the process typically includes:


  • Obtaining a copy of the will and the assets and liabilities of the estate.
  • Negotiation and mediation - many disputes are resolved through negotiation or mediation, without the need for a full court hearing.
  • Filing a claim in court - this must be done within a set timeframe, usually within 6-12 months of probate being granted.
  • Court involvement - the High Court or Family Court will consider the claim and review supporting evidence, which may include medical records, witness statements, or details of family circumstances.
  • Court decision - if no agreement is reached, the Court will make a decision about whether the will should be changed or upheld.

 

Every case is different, and the Court will look closely at the individual circumstances. The law aims to balance the wishes of the person who made the will with fairness to those left behind.

 

Things to keep in mind

 

Contesting a will can be stressful, and it may affect family relationships. Timeframes are strict, and the process can be emotionally charged. It is important to seek legal advice early - not just to understand your rights and the process involved, but to help you navigate the situation with clarity and confidence.

A new year often brings fresh plans and new possibilities. For many people, that includes thinking about a change in where, or how, they live. Whether you are planning to buy your first home, move somewhere new, or sell a property in 2026, good preparation starts well before an agreement is signed. Property transactions often take longer than people expect. There are documents to review, decisions to make, and steps that need to happen in the right order. Starting early gives you more control, more confidence, and fewer surprises along the way. It is all about setting yourself up for a smoother journey. If you are thinking about selling A successful sale begins with understanding your property’s paperwork. Taking time now to check a few key areas can save you stress later. Title details: Easements, covenants, and other restrictions can affect how a buyer views your property. Knowing what is on your title helps you prepare for questions before they arise. LIM and property file information: Councils hold a lot of information about your property. Ordering these documents early gives you a clear picture of what a buyer will see. Building work and consents: If you have made alterations, it is important to confirm that the right consents and code compliance certificates are in place. Missing paperwork is one of the most common causes of delays or last-minute renegotiations. Identifying any issues early means you can deal with them on your terms, without pressure once an offer arrives. If you are thinking about buying Buyers benefit just as much from early preparation. A little groundwork now can make you a stronger, more confident purchaser when the right property appears. Understand the agreement: Sale and purchase agreements are legally binding. Knowing the key terms, conditions, and timelines ahead of time helps you move quickly without feeling rushed. Get finance ready: Talking to your mortgage broker or lender early means you will understand what conditions may apply and how much flexibility you have. Plan your due diligence: From building reports to title checks, due diligence is easier when you are not racing the clock. Early advice helps you know what to look for and what questions to ask. The biggest advantage is getting legal advice before you sign, not after. It is about being informed and prepared. Why timing matters When people leave things too late, they often end up making decisions under pressure. Important details get missed. Red flags in contracts or property information go unnoticed. And what should be an exciting life moment becomes unnecessarily stressful for you and your whānau. How early legal advice helps Starting the conversation early means you can: Understand risks and obligations before you commit. Get clarity on timelines, conditions, and key milestones. Move forward smoothly once you are ready to buy or sell. It is all about giving yourself the best chance of a straightforward, stress-free experience. Thinking about a move this year?
