Finding out you need to change an executor can feel unsettling, whether you’re updating your own will or dealing with someone else’s estate. NSW law gives you clear pathways for this, depending on whether the will-maker is still alive. This guide walks through how to change an executor of a will in NSW, what the courts require, and what to do if you’re stuck with a problem executor right now.

When and Why You Might Need to Change an Executor

There are really only two scenarios where an executor change comes up. The first is before death, while the will-maker is alive and wants to update their will. The second is after death, where the estate is already in motion and the change needs court involvement.

Understanding what an executor is actually responsible for helps you work out whether a change is genuinely needed, or whether the issue is more about communication than legal fitness.

Common Reasons Executors Are Replaced

Executors get swapped out for all sorts of practical reasons. Someone might move overseas and can no longer manage the estate’s affairs day to day. Others develop health problems, like dementia, that affect their capacity to act.

Family conflict is another common trigger. If the named executor and the beneficiaries no longer get along, or trust has broken down, it can make sense to name someone more neutral. Sometimes the original executor simply isn’t up to the job. They might be disorganised, slow, or unwilling to communicate with beneficiaries.

Changing Executor of a Will NSW Before Death

If the will-maker is alive and has mental capacity, changing an executor is the easiest version of this process. There’s no court application, no waiting period, and no need to justify the change to anyone.

You can change your will’s executor at any point, for any reason. You don’t need the current executor’s permission, and you don’t need to give them a reason.

How to Update Your Will With a New Executor

The simplest way to change your executor is to make a new will that names a different person. A new will should generally revoke the earlier one, so there’s no confusion later about which version applies.

For a smaller change, a codicil (a formal amendment) can update just the executor clause without rewriting the whole will. In practice, many people prefer a new will anyway. It avoids the risk of a codicil being lost or misplaced separately from the original document.

A common scenario looks like this: a parent names an adult child as executor, but that child later moves overseas or becomes estranged from the family. That prompts a straightforward update via a new will while everyone is still alive and able to agree on the change calmly.

Changing your will after it’s signed needs to follow strict formalities (more on that here), so it’s worth getting legal advice rather than editing the original document yourself. If you’re weighing up what it costs to update or write a new will, a fixed-fee quote upfront removes the guesswork. It’s also worth reviewing a full estate planning checklist while you’re at it, since an executor change is often a good prompt to check the rest of your estate plan too.

Can You Change Executor After Death NSW?

Once the will-maker has died, you can no longer simply write a new will. The law recognises whoever the existing will names as executor, unless something changes that formally.

That said, change is still possible after death. It just moves from being a personal decision to a legal process involving the NSW Supreme Court. The pathway depends on whether probate has already been granted.

Options When Probate Hasn’t Been Granted

If the named executor hasn’t yet applied for probate, they can formally renounce the role. Renunciation is a straightforward document filed with the court. It lets another eligible person, such as a substitute executor named in the will or a beneficiary, step in without a contested court battle.

This is by far the smoother option if the current executor is willing to step aside voluntarily. It avoids the cost, delay, and stress of a formal removal application.

Removing an Executor After Probate Is Granted

Once probate has been granted, the executor has formal legal authority over the estate. At this point, removing them requires a court order, not just a signed form.

The NSW Supreme Court can remove and replace an executor, but it treats this as a serious step. Anyone applying for removal at this stage needs to show real grounds, not just personal dissatisfaction with how things are going.

Legal Grounds for Executor Removal in NSW

Courts don’t remove executors lightly. The role exists because the will-maker trusted a specific person to carry it out, so the Supreme Court generally respects that choice unless there’s a genuine problem.

Misconduct, Incapacity and Conflicts of Interest

Recognised grounds for removal include mismanagement of estate assets, such as spending estate money improperly or failing to keep proper records. Unreasonable delay in administering the estate is another common ground, especially where beneficiaries are left waiting years without explanation.

Incapacity is also relevant if the executor develops a condition that stops them acting rationally in the role. Conflicts of interest matter too, particularly where the executor’s personal interests clash directly with their duty to beneficiaries.

Executor removal applications in the NSW Supreme Court are relatively uncommon compared to routine probate grants. That reflects the court’s general reluctance to step in unless there’s clear evidence of misconduct or incapacity, rather than simple friction between family members.

NSW Court Process and Forms for Executor Change

If renunciation isn’t available and informal resolution hasn’t worked, the next step is a formal application to the Supreme Court of NSW. This sits within the court’s probate jurisdiction, and it typically involves a summons supported by one or more affidavits.

Key Documents and Timeline

The application generally needs an affidavit setting out the grounds for removal, along with supporting evidence such as estate accounts, correspondence, or medical evidence where incapacity is the issue. If there’s a proposed replacement executor, that person usually needs to file their own affidavit confirming they’re willing and eligible to act.

Timeframes vary depending on whether the current executor contests the application. An uncontested renunciation before probate can be resolved in a matter of weeks. A contested removal application after probate can take several months, particularly if the court needs to hear evidence about disputed conduct.

Costs also vary with complexity. A straightforward renunciation is comparatively low-cost. A contested Supreme Court application involves filing fees, legal costs, and potentially costs orders against the losing party. It helps to understand how long the probate process takes in NSW generally, since an executor dispute often adds extra months on top of the usual grant timeline.

Talking to a Problem Executor Before Going to Court

If you’re dealing with a problem executor right now, court action doesn’t need to be the first move. Litigation is expensive and slow, and it can permanently damage family relationships that were already strained.

When Mediation or a Formal Letter Can Help

Start with a clear, written request. Ask the executor for an update on the estate, a timeline for distribution, or an explanation for a decision that concerns you. Many issues come down to poor communication rather than genuine wrongdoing, and a direct conversation resolves them faster than any court form.

If a letter doesn’t get a response, try mediation before litigation. Courts generally treat executor removal as a last resort. They’d rather see beneficiaries and executors resolve disagreements through communication or mediation first. Looking into alternatives to going to court over a dispute can save you significant time and money compared to a contested application.

It’s also worth checking you’re not confusing roles. Understanding how power of attorney differs from an executor role can clear up confusion, since an attorney’s authority ends at death, while an executor’s role only begins then.
