Secret Trusts: Proving an Obligation Outside the Will

What a Secret Trust Claim Asserts

The alleged obligation requires the named recipient to hold or apply the gift for someone else. It must have been accepted during the testator’s lifetime. The testator is the person who made the will. Their informal wish to benefit another person needs closer examination before it can support a secret trust claim.

The will’s wording determines which arrangement you are investigating.

Arrangement	What the will reveals	Evidence to investigate
Fully secret trust	An apparently beneficial gift, with no trust disclosed	The separate instructions and the recipient’s acceptance
Half-secret trust	A trust obligation, with its terms or beneficiaries left undisclosed	The will alongside the communicated terms
Express trust created by the will	The trust’s terms are set out in the will	The operative clauses and property subject to them

The last category belongs to testamentary trust administration. Here, the question is whether communications outside the will impose the alleged obligation.

In Voges v Monaghan [1954] HCA 63, the High Court upheld a secret trust by majority. The disputed issue was whether payments to others were obligatory or left to the recipient’s discretion. Letters and conduct helped establish what had been communicated and accepted.

Identify the property and intended beneficiaries as well as the obligation. An assertion that the deceased wanted someone looked after leaves open what assets were committed and what the recipient had to do. In Kahlon v Kahlon [2025] SASC 37, the South Australian Supreme Court rejected the alleged secret trust. The evidence did not establish the required communication and acceptance. The judgment distinguishes a moral obligation from an enforceable one.

Establish Communication and Acceptance

Build a chronology showing when each instruction reached the recipient and how the recipient responded. Record execution of the relevant will or codicil and the testator’s death as separate events. Preserve exact dates in the working chronology, even where a witness can only give an approximate period.

Half-secret trusts require particular care about timing. In Burke v Public Trustee for the State of South Australia [2022] SASCA 64, the Court of Appeal discusses differing authorities. Guest v Webb [1965] VR 427 applies communication before or at execution. Ledgerwood v Perpetual Trustee Co Ltd (1997) 41 NSWLR 532 permits communication after execution but before death.

Doyle JA leaves the half-secret timing issue open. For a fully secret trust, communication can occur during the testator’s lifetime, including after execution.

That distinction makes the chronology a legal input. Record communications on both sides of execution instead of applying a single timing rule to every claim.

Use the following checklist to assemble the evidence for the estate lawyer’s assessment.

• Identify each person present when the instructions were given. Separate what they heard directly from what another person later told them.
• Preserve letters, messages and attachments in their original form, including evidence of delivery. A draft retained by the testator does not itself show receipt.
• Obtain the relevant will drafts and the solicitor’s file through the appropriate authority. Identify which version each instruction concerns.
• Record the recipient’s actual response. Distinguish an express promise from conduct said to amount to acceptance.
• Compare later acknowledgements with the original instructions. Record changes to the assets, beneficiaries or alleged payment terms.
• Keep conflicting witness accounts side by side. Identify the disputed words instead of combining them into an agreed narrative.

Acceptance can be express or inferred from conduct, but awareness of a family expectation alone does not establish acceptance of the alleged obligation. In Kahlon, knowledge of the insurance and the executor appointment did not supply the missing communication and acceptance. Avoid treating a person’s appointment as executor as an answer to whether they accepted a separate obligation over a gift.

Follow the Gift and Subsequent Dealings

Reconcile the estate’s payment to the named recipient before attributing later transfers to the alleged secret trust. Match the estate account debit to the recipient account credit. Record the distribution authority and the asset or entitlement being paid.

For each subsequent transfer, retain the statement reference and identify the receiving account where the records establish it. Keep a running total of payments said to discharge the obligation. Distinguish that total from money spent on the recipient’s own expenses or transferred between their accounts.

A Fictional Split Payment

Suppose an estate distributes $240,000 to Alex. Morgan alleges that Alex accepted an obligation to pay Morgan $90,000 from that inheritance. Two weeks after the distribution, Alex transfers $30,000 to Morgan. Six weeks later, a second transfer of $20,000 reaches the same account.

The schedule shows $50,000 paid and a $40,000 difference against the alleged $90,000 obligation. If those are the only movements, $190,000 of the inheritance remains in Alex’s account. These figures describe the fictional records and the allegation separately.

Morgan says the payments partly perform the agreement. Alex says they repay an unrelated loan. Obtain the loan correspondence and compare the payment references with any acknowledgement of the alleged trust. The same pair of transfers can fit competing explanations until the communications establish their purpose.

In Voges, subsequent payments formed part of a wider evidentiary picture. Preserve the accompanying correspondence and admissions alongside the bank entries. A spreadsheet that simply labels both transfers as trust payments would conceal the dispute it must help the lawyer assess.

For a substantial statement bundle, FinTrace saves lawyers and forensic accountants hours of manual comparison by following transfers across the supplied accounts. Findings cite the source PDF filename and page, so the supporting transaction evidence is directly at hand. The searchable ledger gives the estate team a practical way to examine payments beside the communications chronology.

Resolve Ownership and Administration Consequences

Establishing a secret trust determines the recipient’s obligations over the relevant gift. Its failure does not produce the same outcome in every case. The will’s wording and the reason for failure affect who is entitled.

Where a fully secret trust is unproved, the apparently absolute gift can remain beneficial to the named recipient. Where the will itself discloses a trust, failure to establish its beneficiaries can leave property held for the residue or those entitled on intestacy. Burke discusses that consequence for a half-secret trust with uncertain objects. A failed claim therefore needs analysis of the gift itself before the estate makes a distribution decision.

Prepare the records for the possible outcomes, while leaving disputed ownership and distribution decisions to the estate lawyer. The record set needs more than the balance currently visible in one account.

• Retain the grant, operative will and estate accounts, together with the authority for each distribution.
• Preserve statements covering receipt of the gift and every later period needed to follow its movement.
• Identify assets bought with the money and retain purchase and sale records. State which links are proved and which remain disputed.
• Keep records of repayments, releases and any agreement said to discharge the obligation.
• Record the current holder of each identifiable asset and any threatened transfer for the lawyer’s preservation assessment.

A personal claim seeks relief against a person, while a proprietary claim asserts rights in identified property or its traceable proceeds. Keep those questions separate in the instructions to the forensic accountant. The payment schedule must show what was received and where it went, while the communications evidence supports the alleged obligation.

If money has already moved, give the estate lawyer the source records and the disputed explanations together. Identify the asset requiring preservation, the proposed respondent and the transaction that connects them. That lets the lawyer assess recovery or interim protection against the actual evidence, without treating a transfer match as a decision about ownership.
