How do the four types of estate dispute differ?
A family provision claim asks whether provision should be made for an eligible person. A will-validity challenge asks whether a particular will is legally valid. Will construction concerns the meaning of the will, while administration disputes concern how the estate is managed. More than one issue can arise in an estate, but each needs its own legal basis and evidence.
Family provision claims
The Court considers whether adequate provision has been made for an eligible person’s proper maintenance, education or advancement in life. A claim can arise under a will or on intestacy, where an estate is distributed without an effective will. It does not necessarily question the will’s validity. See section 59 of the Succession Act 2006 (NSW).
- Who may apply?
- The categories in section 57 of the Succession Act 2006 (NSW) include a spouse or de facto partner at death, a child, a former spouse, a qualifying dependent grandchild or household member, and a person living in a close personal relationship with the deceased at death. The precise statutory conditions matter. Applicants eligible only as a former spouse, qualifying dependent grandchild or household member, or close-personal-relationship applicant must also establish factors warranting the application under section 59 of the Succession Act 2006 (NSW). Eligibility does not guarantee an order.
- Typical evidence
- The relationship and any dependency, the applicant’s financial circumstances and needs, estate assets and liabilities, and the circumstances of other beneficiaries. Section 60 of the Succession Act 2006 (NSW) lists matters the Court may consider.
- Timing
- Generally within 12 months of death, subject to the out-of-time provisions explained above. Under section 58 of the Succession Act 2006 (NSW), the application is made when filed in the Court registry; notifying the executor is not the same as filing.
- Possible outcomes
- An order for provision from the estate, an agreed resolution, or no additional provision. The Court does not simply divide the estate equally because a relative considers the will unfair.

Will-validity challenges
This dispute concerns whether a will should be admitted to probate. Issues can include testamentary capacity, knowledge and approval, undue influence, forgery, signing requirements, revocation or a later will. An allegation needs evidence; dissatisfaction with the size of a gift does not itself make a will invalid. The Supreme Court of NSW’s contested-proceedings guidance explains these grounds and the need for a relevant interest.
- Who may apply?
- A person with a relevant interest in the probate outcome, such as a beneficiary under a different will said to be the last valid will. Being eligible for family provision does not, by itself, give someone an interest entitling them to challenge probate or lodge a probate caveat.
- Typical evidence
- The will and earlier wills, drafting and signing records, witness accounts and, where relevant, medical evidence about capacity at the time the will was made. The evidence needed depends on the alleged ground.
- Timing
- Obtain advice before probate is granted and assets are dealt with wherever possible. A caveat or other procedural step may be relevant, but has its own requirements. The family-provision 12-month limit is not a general deadline for a validity challenge.
- Possible outcomes
- The disputed will may be admitted to probate or rejected. An earlier valid will or intestacy rules may then govern the estate, depending on the findings. This does not necessarily give the challenger a larger share.
Will-construction disputes
“Construction” means interpreting a will’s words and their legal effect, for example identifying the property covered by a gift or the people within a class of beneficiaries. It is different from challenging validity or seeking further provision. Part 54 of the Uniform Civil Procedure Rules 2005 (NSW) permits relevant estate questions to be determined by the Supreme Court.
- Who may apply?
- An executor, administrator or person with a relevant interest affected by the interpretation, depending on the question and orders sought. Family-provision categories are not the eligibility test for every construction proceeding.
- Typical evidence
- The complete will and codicils, relevant asset and beneficiary information, and any admissible evidence that assists interpretation. Section 32 of the Succession Act 2006 (NSW) limits when evidence of the deceased’s intention can be admitted.
- Timing
- Seek advice before distributing affected assets. Timing depends on the dispute and relief sought. If the concern is that the will contains a drafting error requiring rectification, separate requirements and time limits may apply under section 27 of the Succession Act 2006 (NSW).
- Possible outcomes
- A determination of the will’s meaning or directions about how to give effect to it. Interpretation does not itself authorise rewriting a will to provide a preferred distribution.
Executor and administration disputes
These concern the handling of an estate: accounts, assets, liabilities, distributions or the conduct of an executor or administrator. Different procedures address different problems. The Supreme Court of NSW’s estate-accounts guidance distinguishes passing accounts from issues requiring a separate administration suit.
- Who may apply?
- A beneficiary, executor, administrator or another person with a relevant interest, depending on the application. A creditor’s interest in payment is different from a beneficiary’s interest in distribution; neither should be assumed to confer every right of challenge.
- Typical evidence
- The will and grant, estate accounts, asset and liability records, receipts, distribution information and correspondence identifying the concern and any response.
- Timing
- Act promptly if assets may be lost or distributed, or a Court notice requires a response. The applicable time limits and steps depend on the complaint and remedy, rather than the family-provision deadline.
- Possible outcomes
- Orders for accounts, directions about administration or other relief suited to a proven breach. A disputed payment may need separate proceedings rather than being resolved when accounts are passed. See Part 54 of the Uniform Civil Procedure Rules.
Does the estate pay everyone’s legal costs?
No. Do not assume that the estate will pay your costs simply because the dispute concerns a will, or that a successful claim guarantees reimbursement of all your legal fees. Subject to applicable legislation and rules, costs are discretionary under section 98 of the Civil Procedure Act 2005 (NSW).
The Court may order an unsuccessful party to pay another party’s costs. An executor’s proper administration expenses are also different from an individual claimant’s litigation costs. The Supreme Court’s contested-proceedings guidance warns about adverse costs, while its estate-accounts guidance explains scrutiny of estate expenditure. Obtain advice about likely costs, funding and settlement options before proceedings.
Can an estate dispute be resolved without a hearing?
Negotiation or mediation may help parties reach an agreement. The Court can refer proceedings to mediation, but settlement is not guaranteed. The Supreme Court of NSW’s mediation guidance explains the process. Discussions do not themselves extend a filing deadline or replace any required Court step.
What should you prepare for an appointment?
- The will and any codicils or earlier wills available to you.
- The date of death and death certificate, if available.
- Any grant of probate or letters of administration, notices and Court documents.
- Information about your relationship to the deceased and your interest in the estate.
- Relevant asset, liability, financial, medical or dependency information.
- A short chronology, correspondence and any known filing or response dates.
These are preparation suggestions; the documents needed depend on the dispute. Do not delay obtaining advice while gathering them. Our contested-estates solicitors in Liverpool can assess the appropriate pathway and the steps needed to protect your position.
