Contested will litigation in NSW

We run contested will claims, capacity and undue influence challenges and family provision disputes in NSW.
Two Mullane Lindsay solicitors reviewing legal documents

When an estate dispute cannot be resolved by agreement, you need litigators who will run it properly. Contested will matters are heard in the Supreme Court of NSW and follow their own procedural framework, from affidavit evidence and subpoenas to expert medical evidence on capacity. We act for claimants and for executors defending an estate, from our offices in Newcastle, for clients across the Hunter and NSW.

How we help

We assess the claim hard, then run it firmly and efficiently. We:

  • Give you a realistic view of prospects and costs before proceedings start.
  • Bring or defend family provision claims and challenges to a will’s validity.
  • Build the evidence, including medical records, attendance notes and expert evidence on capacity.
  • Represent you at mediation, where most matters resolve, and at a final hearing if they do not.

What does contested will litigation involve?

Where a matter cannot be negotiated, it proceeds through the Supreme Court: the applicant files an originating application with affidavit evidence; the executor responds and defends the will; the parties exchange documents and may issue subpoenas for medical and financial records; expert medical evidence is obtained where capacity is in issue; the parties attend mediation; and, if it does not resolve, a judge decides at a final hearing. It can be lengthy and costly, so prospects and cost should be assessed at the outset.

FAQs

If it cannot be resolved by agreement, it proceeds in the Supreme Court: filing an originating application with affidavit evidence, service on the executor and interested parties, discovery and subpoenas, expert medical evidence where capacity is in issue, mediation (where most matters settle), and a final hearing if needed. Early advice on prospects and cost is essential.

By the test from Banks v Goodfellow: the will-maker must have understood that they were making a will and its effect, the nature and extent of their estate, and the claims of those who might expect to benefit, free of a disorder of the mind affecting those decisions. A dementia diagnosis is not decisive, as capacity is judged at the moment the will was signed.

It must be shown that the will-maker’s free will was actually overborne, not just that someone had influence. Relevant factors include the deceased’s susceptibility, the influencer’s opportunity and control, actual pressure, and a will reflecting the influencer’s wishes. It is usually inferred from circumstantial evidence, and the burden rests on the person alleging it.

Generally costs follow the event, but the court has a broad discretion. Where the litigation was reasonably necessary, costs may be paid from the estate; where a party acted unreasonably, indemnity costs may be ordered. Costs should always be weighed against the value of the estate.
