Escrow in residential construction: how it protects owner funds

In a standard Australian residential build, you pay a deposit and then a series of progress payments tied to stages: base, frame, lock-up, fixing, and completion. Each payment is triggered by a progress claim from your builder.

The moment you pay, the money typically moves into the builder's general operating account. It is not held in trust, it is not ringfenced for the trades who did that stage, and it is not separated from the builder's other costs. Legally, your funds become the builder's funds on receipt.

This is not a trick by any one builder. It is how the structure is built. Builders finance jobs out of their own pocket and lean on incoming payments to keep multiple projects moving. The arrangement was designed without subcontractors or owners at the table, so the money sits where it suits cash flow, not where it protects you.

The Australian Securities and Investments Commission explains insolvency basics for unsecured creditors, and the position is sobering: see ASIC's guidance on insolvency. When funds are mixed into one account, owners and subbies usually rank as unsecured creditors if that account runs dry.

A single shared account is fine while cash flows. It fails quietly, and then all at once, when it does not.

None of these failures is one builder's neglect. The structure produces them, which is why a different structure is the only real fix.

Escrow flips the default. Instead of the money going to the builder to spend, it is held by a separate, regulated party and released only when verified conditions are met. The builder cannot reach in and take it early.

On BuildFair, owner deposits and progress payments are held in regulated custody with BuildFair banking partner Kobble, separate from the builder operating account. Kobble operates under AFSL 545391 (Yondr Money Pty Ltd). This is genuine regulated custody, not a promise written into a contract you hope is honoured.

The distinction matters. A builder's bank account is the builder's money. A regulated custody account holds funds outside that operating account, governed by the project rules you and your builder agreed, and released on conditions rather than on request. It behaves more like a trust account than a trading account.

BuildFair itself does not directly hold your money, and is not currently required to hold its own AFSL. The cash sits with the regulated banking partner. BuildFair holds the project rules, the records, and the audit trail. That separation is deliberate, and we explain the full architecture on the Trust and security page.

Money does not move because someone asks nicely. It moves when a defined, recorded condition is satisfied.

Every one of these conditions is a checkpoint the money has to clear. That is the practical difference between escrow and a shared operating account.

Holding money separately only helps if you can prove what happened to every dollar. BuildFair records the project rules, payments, and approvals in a double-entry, hash-chained ledger. Double-entry means every dollar in has a matching dollar out, so the books must balance to the cent.

Hash-chaining makes the record tamper-evident. Each entry carries a cryptographic fingerprint of the entries before it, so a quietly altered past entry would break the chain and show up. The audit trail is permanent, not editable.

Reconciliation matches bank feeds against ledger postings, and settlement finality is marked only on confirmed bank evidence, never on an acknowledgement alone. In plain terms, a payment is only treated as truly settled when the bank confirms it landed.

Identity matters too. Builders, owners, subcontractors, and suppliers are verified through Sumsub before activation, so the parties on each side of a payment are who they say they are. Subcontractor removal carries a notice period and cooling-off window, with over-invoicing detection to guard against phoenix behaviour.

The same build, the same payments, two very different outcomes when something goes wrong.

Variations are the only thing requiring dual approval. Ordinary payouts do not, so the build does not stall every time a routine claim comes through.

Escrow protects how your money is held and released. It does not insure against every risk, and it is not a substitute for a sound contract or a careful builder choice. You still need a contract you understand, and we have a guide on negotiating your building contract.

Regulated custody does not make BuildFair the holder of your funds, and it is not a claim that any specific outcome is guaranteed. The banking partner holds the cash under its AFSL, and the protections flow from that regulated framework plus the project rules.

If a dispute escalates beyond what the platform records can resolve, that is a matter for your lawyer, your state tribunal such as VCAT or its equivalent, or Legal Aid. We do not provide legal advice, and nothing here changes your statutory rights.
