Can a Grandchild Contest a Will in NSW?
Not every grandchild has the right to contest a grandparent’s Will in New South Wales. While family provision claims are commonly associated with spouses and children, grandchildren are not automatically entitled to make a claim under the Succession Act 2006 (NSW).
In limited circumstances, a grandchild may qualify as an “eligible person” and seek provision from an estate. This article explains when a grandchild may be entitled to contest a Will, what the law means by “dependency” and “factors warranting”, and how the Court approaches these claims.
Are Grandchildren “Eligible Persons” Under the Succession Act 2006 (NSW)?
Sometimes — but not automatically.
Under section 57 of the Succession Act 2006 (NSW), a grandchild may only be considered an eligible person if they can establish that, at some point:
- they were wholly or partly dependent on the deceased, and
- they are a grandchild of the deceased; or
- they were a member of the deceased’s household in a substantial way.
Importantly, satisfying one of these categories does not guarantee a successful claim. Even if eligibility is established, the grandchild must also demonstrate that there are “factors warranting” the Court’s intervention.
Only once both eligibility and warranting factors are established will the Supreme Court of NSW consider whether the Will made adequate provision for the grandchild’s proper maintenance, education, or advancement in life.
What Does “Dependency” Mean?
Dependency is assessed as a matter of practical reality. The Court will consider whether the deceased provided regular and ongoing financial support, such as:
- payment of living or schooling expenses
- providing accommodation
- meeting day-to-day necessities
Occasional gifts, sporadic assistance, or emotional closeness alone are not sufficient to establish dependency. The support must be meaningful and ongoing.
What Are “Factors Warranting” a Claim?
“Factors warranting” refer to circumstances that make it appropriate for the Court to intervene in the deceased’s testamentary arrangements.
For grandchildren, this often involves situations where the deceased effectively acted as a parent, such as:
- long-term caregiving responsibilities
- assuming responsibility for housing, education, or daily care
- a relationship that went beyond the usual grandparent-grandchild bond
The Court assesses these factors against prevailing community standards to determine whether the deceased owed a moral or social obligation to provide for the grandchild.
Case Example: Adult Grandson’s Claim Dismissed
A recent Supreme Court of NSW decision highlights the high threshold adult grandchildren must meet.
In Broadus v Cradduck [2025] NSWSC 402, the deceased left his entire estate to his only surviving son. An adult grandson, who was not named as a beneficiary, brought a family provision claim alleging financial and emotional dependency.
The Court considered whether:
- the grandson was an eligible person
- factors warranted provision being made
- the Will reflected the deceased’s testamentary intentions
Despite the grandson’s claims, the evidence showed only sporadic visits and occasional financial assistance. He was not found to be a member of the deceased’s household, nor financially or emotionally dependent in any meaningful way.
The Court held that prevailing community standards did not impose any obligation on the deceased to provide for an adult grandchild, particularly where doing so would prejudice the primary beneficiary. The Will was found to reflect the deceased’s rational and deliberate intentions, and the claim was dismissed
Key Takeaway for Grandchildren and Families
This decision reinforces that adult grandchildren face a high bar when seeking provision from a grandparent’s estate. Establishing eligibility alone is not enough — compelling evidence of dependency and factors warranting Court intervention is essential.
