You discover your parent has died. The will leaves everything to their second spouse. You and your siblings from the first marriage get nothing.
Can you challenge that?
Yes. Sometimes.
The answer depends on three things that most families get wrong: the type of claim you can actually bring, what the court is really looking at, and how much of the estate is genuinely available to contest.
This article walks you through the practical framework courts use when children from a first marriage say the will failed them, and what you need to understand before deciding whether a claim makes commercial sense.
Key Takeaways
- Second marriage does not block claims, children from a first marriage can contest a will that leaves everything to a second spouse, but there is no automatic right to inherit
- The claim is about adequate provision, courts ask whether the will made proper provision for your maintenance, education, or advancement in life, not whether you feel entitled to a share
- Adult children face a higher bar, if you are financially independent, the threshold for proving inadequate provision is significantly higher than for dependent children
- Estate structure matters more than the will, jointly owned property, superannuation, and assets outside the estate may leave little for anyone to contest, regardless of what the will says
- Competing claims reshape outcomes, when a second spouse, stepchildren, and first-marriage children all have valid claims, the question becomes who has the stronger need
- Time limits are strict, you typically have 6 to 12 months from death to bring a family provision claim, depending on your state, and extensions are difficult to obtain
Can Children From a First Marriage Contest a Will in Australia?
You can.
Australian law gives children the right to bring a family provision claim if they believe the will (or the estate) failed to make adequate provision for their proper maintenance, education, or advancement in life.
It does not matter whether your parent left everything to a second spouse, a charity, or a stranger. If you are an eligible person under your state’s succession law, you can make a claim.
But here is what most people misunderstand.
You are not contesting the will’s validity. You are not arguing the will was forged, signed under duress, or made when your parent lacked capacity. Those are different claims.
A family provision claim accepts the will is valid. What you are saying is: “This will left me without adequate provision, and the court should fix that.”
The distinction matters because families often conflate two separate questions. One is: “Was the will properly made?” The other is: “Did it make proper provision for me?” You can lose on the first and still win on the second.
A valid will can still be challenged if it fails to provide adequately for eligible children. The question is not whether the will is real, it is whether it leaves you with enough, in the circumstances.
What Kind of Claim Do Children Actually Bring?
You bring what is called a family provision claim (sometimes called a testator’s family maintenance claim, depending on the state).
Each Australian state and territory has succession legislation that allows certain people, spouses, children, dependants, to apply to court for a larger share of the estate if the will (or intestacy) left them inadequately provided for.
The legislation varies slightly by jurisdiction, but the principles are consistent:
- You must be an eligible person (children almost always are)
- You must show the will failed to make adequate provision for your proper maintenance, education, or advancement in life
- The court weighs your claim against the size of the estate, competing claims, and what is “adequate” in all the circumstances
If you succeed, the court can rewrite the distribution. It might carve out a lump sum for you, give you a property, or adjust the shares between you and the second spouse.
But the court is not required to treat you equally. It is not required to give you half. The test is adequacy, not fairness.
If you are thinking about a family provision claim, start by asking: “Can I explain, with clarity, why the provision I received (or did not receive) is inadequate for my needs?” If you cannot articulate that in plain language, you may not have a strong claim.
Why a Second Spouse Often Becomes the Point of Conflict
When your parent remarries and updates the will to leave everything to the new spouse, it triggers what feels like a zero-sum contest: you versus them.
That feeling is understandable. But the legal analysis is more complex.
A second spouse is also an eligible person. In most cases, they have a strong claim to provision from the estate. Courts recognise that spouses, particularly those who lived with the deceased and may have been financially dependent, need to be provided for.
So the dispute is rarely “children versus an undeserving second spouse.” It is almost always a question of competing claims. The court is balancing your need against theirs, then slicing a finite estate accordingly.
And here is the uncomfortable commercial reality.
If the second spouse was living in the family home, that home was jointly owned, and superannuation went directly to them as a binding death benefit nomination, the “estate” may be a modest bank account and some personal effects. Even if you win your claim, the amount available to satisfy it may be far smaller than you expected.
That is why you cannot look at the will in isolation. You need to understand the estate structure before deciding whether a claim is worth pursuing.
A second spouse is not an obstacle to your claim, they are a competing claimant. The question is not whether they should get something; it is whether the estate is large enough to provide adequately for both of you.
What Do Courts Actually Look At When Deciding Adequate Provision?
Courts do not apply a formula. There is no rule that says “children get 40%, spouses get 60%.”
Instead, courts apply a two-stage test established in Singer v Berghouse, the leading High Court case on family provision claims. The framework is this:
Stage one: Has the applicant (you) been left without adequate provision for your proper maintenance, education, or advancement in life?
Stage two: If yes, what provision should the court order, having regard to all the circumstances?
The court considers:
- Your financial position and needs, are you financially independent, or do you rely on income support? Do you have dependants? Health issues? A mortgage?
- The size and nature of the estate, a $5 million estate allows more flexibility than a $200,000 estate. Illiquid estates (property, shares) are harder to carve up than cash.
- The relationship between you and the deceased, were you close? Estranged? Did your parent support you financially during their life?
- Competing claims, who else is claiming, and what are their needs? If the second spouse has no income and the estate includes the family home, their need may be prioritised.
- Any contributions you made, did you care for your parent in their final years? Help run the family business? Courts weigh moral claims alongside financial ones.
- Testamentary intentions, what the deceased wanted matters, but it is not determinative. A court can override the will if provision was inadequate.
If you are an adult child who is financially independent, owns property, and had little contact with your parent in their final years, you will face a high bar. The court may find that no further provision is warranted.
If you are studying full-time, have a disability, or were genuinely financially dependent on your parent, your claim strengthens.
If you can articulate a clear gap between what you need and what you received, and you can show that the estate can afford to fill that gap without leaving the second spouse destitute, you have a viable claim.
Before bringing a claim, map out your financial position honestly. Courts do not reward adult children who simply feel entitled to a share. They provide for those who can demonstrate need.
How Adult Children Differ From Dependent Children in Will Contests
If you are an adult child, courts start from the position that you should be self-sufficient.
That does not mean you cannot make a claim. But the threshold is higher.
Courts have repeatedly said that a parent’s moral obligation to provide for an adult child is less than the obligation to a dependent child. If you have finished your education, you are employed, you own a home, and you have no unusual financial burdens, a court may find that the will made adequate provision, even if that provision was zero.
Contrast that with a child who is:
- Still at school or university and financially dependent on the estate
- Living with a disability that limits earning capacity
- Facing significant health issues or caring responsibilities
For dependent children, courts are far more willing to carve out provision. The estate may need to fund education, medical expenses, accommodation, or long-term support.
And here is the difficult question courts ask adult children:
“What provision should have been made for you that was not?”
If you cannot answer that with specificity, if your claim is simply “I expected to inherit something because I am his child”, you may not succeed.
If you can answer it, “I need help with a house deposit and I have no other means of affording it” or “I left my job to care for Mum in her final two years and now I am financially disadvantaged”, you have something to work with.
Being a child of the deceased gives you standing to bring a claim. It does not, by itself, mean the court will award you provision. The question is always: what is adequate in the circumstances?
Why the Estate May Be Smaller Than It Looks
Families often overestimate the value of the estate available for contest.
You see the family home. You know your parent had superannuation. You assume the estate is worth $2 million.
But then you discover:
- The home was held as joint tenants with the second spouse. It passed to them automatically on death, outside the will.
- Superannuation went to the second spouse via a binding death benefit nomination. Not part of the estate.
- The bank accounts were joint accounts. Also outside the estate.
What is left in the estate? Maybe a car, some furniture, and $50,000 in a savings account.
Even if you succeed in a family provision claim, the court can only redistribute what is in the estate. It cannot claw back jointly held property or superannuation unless you bring a separate application to “notionally” include those assets, and those applications are difficult, expensive, and rarely succeed.
This is the commercial trap that catches adult children off guard.
The will might say “I leave everything to my wife,” but if “everything” was already hers by operation of law, there is nothing left to contest.
Before you commit to litigation, you need to understand:
- What assets are held in the estate?
- What assets passed outside the will?
- What liabilities does the estate have? (Debts, funeral costs, legal fees all come out first.)
- What is the net value available for distribution?
If the estate is modest and litigation could cost $50,000 to $150,000, you need to ask whether a contest makes financial sense, even if you have a strong legal claim.
Obtain a full asset and liability schedule early. You cannot assess whether a claim is commercially viable until you know what is actually in the estate and what sits outside it.
What Happens if the Home or Superannuation Sits Outside the Estate?
This is where estate disputes get messy.
If your parent owned the family home jointly with their second spouse, that property passes to the spouse automatically on death under the principle of survivorship. It does not form part of the estate. The will is irrelevant to that asset.
The same applies to superannuation with a binding death benefit nomination. The super fund pays directly to the nominated beneficiary. It does not go through the estate.
For children from a first marriage, this structure can feel like the estate was deliberately drained before death to cut you out.
Sometimes it was. Sometimes it was just how the assets were structured and no one thought through the consequences.
Either way, your options are limited.
You can apply to “notionally” include assets that sit outside the estate, but that is a separate, difficult application. You would need to show that the deceased intended the asset to be dealt with as part of the estate, or that it was transferred to defeat your claim. Courts are cautious about unwinding joint ownership or superannuation structures.
In practical terms, if the second spouse holds most of the wealth outside the estate, your family provision claim may not deliver the outcome you hoped for, even if the court agrees you were inadequately provided for.
This is why early legal advice matters. You need to know what is contestable before you decide to contest it.
The “estate” is not the same as “everything your parent owned.” Assets held jointly, superannuation, and life insurance often sit outside the estate, and you cannot redistribute what is not there.
Blended Families, Stepchildren, and Competing Claims
If your parent remarried and there are stepchildren involved, the dispute becomes a multi-party contest.
Stepchildren may also be eligible to bring family provision claims if they were treated as children of the deceased or were financially dependent on them.
You now have:
- A second spouse claiming provision
- Adult children from the first marriage claiming provision
- Potentially stepchildren claiming provision
- Potentially dependent children from the second marriage
The estate is finite. The claims are not.
Courts decide these disputes by ranking need, not by allocating shares. If the second spouse has no income and nowhere to live, the court may prioritise their claim over yours, particularly if you are financially independent.
If a dependent stepchild was being supported by the deceased and has no other means of support, their claim may also rank ahead of yours.
If there are multiple adult children with similar claims, the court may divide the available provision between you, but again, only after satisfying the claims of those with greater need.
This is why competing claims reshape outcomes. A claim that looks strong in isolation may weaken significantly when the court is balancing five different applicants against a $500,000 estate.
Before you bring a claim, you need to understand:
- Who else is likely to claim?
- What are their financial positions and needs?
- How large is the estate, and can it satisfy all claims?
If the estate cannot satisfy everyone, you may end up with a smaller outcome than you expected, or a costly legal fight that consumes the estate in legal fees.
In multi-party estate disputes, early mediation or settlement negotiations often deliver better outcomes than litigation. Once legal costs erode the estate, everyone loses.
Estrangement, Relationship History, and Moral Claims
What if you were estranged from your parent?
You can still bring a family provision claim. Estrangement does not disqualify you as an eligible person.
But it weakens your claim.
Courts weigh the nature and quality of your relationship with the deceased. If you had no contact for 20 years, did not attend their funeral, and made no effort to maintain the relationship, a court may find that the deceased had no continuing moral obligation to provide for you, particularly if you are financially independent.
If the estrangement was caused by the deceased (they abandoned you, refused contact, or treated you poorly), courts may take a different view. The reason for the estrangement matters.
Courts also consider whether you contributed to the deceased’s welfare. Did you care for them in old age? Help manage their affairs? Support them financially? Those contributions can strengthen a claim, even if the relationship was otherwise strained.
Conversely, if you actively damaged the relationship or behaved in ways that justified the deceased’s decision to exclude you, the court may uphold the will.
What you cannot do is weaponise estrangement. You cannot ignore your parent for years, then claim provision simply because the will excluded you. Courts look at the full picture: your need, their intentions, and the history of the relationship.
Estrangement does not block a claim, but it significantly affects the court’s assessment of whether adequate provision was made. The reason for the estrangement and your financial need will determine whether the claim succeeds.
How Long Do You Have to Bring a Family Provision Claim?
Time limits for family provision claims are strict, and they vary by state.
In New South Wales, you must bring a claim within 12 months of the date of death.
In Victoria, it is 6 months.
In Queensland, it is 9 months.
Other states have similar timeframes.
If you miss the deadline, you need to apply for leave to bring the claim out of time. Courts rarely grant extensions unless you can show a good reason for the delay and that granting leave would not prejudice other beneficiaries.
“I did not know I could make a claim” is not usually a good reason.
“The executor hid assets and I only discovered them recently” might be.
The practical point: if you think you have a claim, get legal advice immediately. Do not wait until month 11 to start thinking about it. Estate disputes take time to investigate, prepare, and negotiate. Waiting too long leaves you with no room to manoeuvre.
Time limits run from the date of death, not the date of probate. Do not wait for the estate to be distributed before seeking advice. Once assets are distributed, clawing them back is harder.
What to Do Early if You Think a Claim May Be Coming
If you are a child from a first marriage and you believe the will left you inadequately provided for, here is what you do early:
Get independent legal advice within the first month. Not from a friend, not from Google. From a lawyer who litigates estate disputes.
Obtain a copy of the will and any earlier wills. You need to see what provision (if any) was made for you, and whether the will changed after the second marriage.
Map the estate structure. Find out what assets are in the estate and what sits outside it. This determines whether a claim is commercially viable.
Assess your financial position honestly. Courts care about need, not feelings. If you are financially independent and were estranged from your parent, your claim may be weak regardless of the size of the estate.
Understand who else is claiming. If the second spouse, stepchildren, and other siblings are all making claims, the estate may not stretch far enough to satisfy everyone.
Consider early negotiation. Estate disputes are expensive. If you can negotiate a settlement early, before litigation costs erode the estate, you may achieve a better outcome than fighting to the end.
Do not delay. Time limits are strict. Waiting months to “see what happens” can cost you the right to bring a claim at all.
If you are the executor or the second spouse defending a claim from first-marriage children, the advice is similar: get early legal advice, understand the strength of their claim, and consider whether settlement makes sense before costs spiral.
Estate disputes are not about winning. They are about achieving the best possible outcome for your circumstances. Sometimes that means negotiating. Sometimes it means litigating. But it always means understanding the commercial reality of what you are fighting over.
The Question You Should Be Asking Your Lawyer
Can you explain, in plain language, what provision the court is likely to award me, and whether the estate can afford it?
If your lawyer cannot answer that question with clarity, if they talk in vague terms about “fairness” or “what you deserve”, you may not be getting the strategic advice you need.
The right lawyer will walk you through the two-stage test courts apply, assess the strength of your claim against competing claims, and tell you whether the estate is large enough to make litigation worthwhile.
They will not promise you a share. They will tell you what is realistic, what it will cost, and what the commercial risks are.
That is the advice that helps you make a decision, not just start a fight.
Final Thoughts: Clarity, Not Entitlement
Children from a first marriage can contest a will that leaves everything to a second spouse. But contesting and winning are not the same thing.
The question is not whether you feel entitled to a share. The question is whether the will made adequate provision for your proper maintenance, education, or advancement in life, and whether the estate can afford to provide more.
If you are financially independent, had limited contact with your parent, and the estate is modest, your claim may not succeed.
If you have genuine financial need, you were financially dependent on your parent, and the estate is substantial, you have a stronger claim.
If the estate was structured so most assets sit outside the will, even a strong legal claim may deliver a disappointing commercial outcome.
The right lawyer will not sell you certainty. They will give you clarity. And clarity is the most powerful tool you can take into any estate dispute.
