Contesting a will in NSW can be done only after a person has died and either before or after a grant of probate. A will can be challenged where it is thought to be unfair, fraudulent, or undue influence was used on the testator when the Will was drafted. You should contact a solicitor as soon as possible as time limits to your claim may apply.

Who can contest a Will?

An interested person can contest a will in the NSW Supreme Court. You are considered an ‘interested person’ if you are:

  • A person named in a previous Will as an Executor
  • A person named in a previous Will as a beneficiary
  • A person named in the Will as a beneficiary
  • A person not named that would be entitled to the estate is there was no will


Challenging The Validity Of A Will

Family Provision Claim

If you are eligible person and you have not been adequately and properly provided for, you may bring a claim for provision or further provisions from the deceased’s estate.

Testator Lacked Testamentary Capacity

If the testator lacked capacity when they instructed and executed the will in question, then it is invalid. The test for capacity was established in Banks v Goodfellow(1870) 5QB 549. Briefly, these principles are broadly explained as:-

    1. The testator understood that he/she is making a Will and what it means;
    2. Recalled the nature and extent of their property in general;
    3. Understood and appreciated any moral obligations they may have towards family, and
    4. He/she was of sound mind.


If the will is subject to fraud then it is invalid. Typically this is done in cases where a beneficiary is attempting to benefit and/or benefit a greater share than they would otherwise be entitled.


Undue Influence

If it can be established that the testator was under some form of undue influence at the time of executing the will the will be declared invalid. This influence is not required to be psychical in nature but can also include emotional and psychological



In cases of forgery the will will be ruled to be invalid.
