Unregistered second mortgages: what they are, and the registered alternative

Three phrases get used almost interchangeably when a business owner wants a short-term loan behind their bank: unregistered second mortgage, caveat loan and second mortgage. They aren’t the same thing, and the difference decides how your loan is documented, what shows on your title and, for us, which structure we use. The quickest way to sort it out is to ask one question first: which state is the property in?

What is an unregistered second mortgage?

It’s a mortgage document you sign, giving a lender a charge over your property, that is never lodged for registration at the land titles office. The paper is real and binding between you and the lender. What it lacks is a place on the public register.

Without registration, the lender’s interest is equitable rather than legal. Western Australia’s titles office spells this out in its caveat guidance: a lender in this position claims “an interest as equitable mortgagee” by virtue of a mortgage of a stated date. That wording is a neat summary of the whole concept — a mortgage exists, but the lender’s protection comes from a different document.

Where does the caveat come in?

An unregistered mortgage on its own is invisible to anyone searching the title. So the lender lodges a caveat, which puts a warning on the register. Land Services Victoria describes a caveat as a document a person with a legal interest in a property can lodge, after which a note on the title tells prospective buyers that a third party might have rights over the property.

Put the two together — a signed mortgage plus a caveat protecting it — and you have the structure behind a short-term caveat loan. That’s exactly how we write caveat loans on Victorian property. For the detail on that state, see caveat loans in Victoria.

What is a registered second mortgage?

A registered second mortgage goes all the way. The mortgage is lodged with the state land registry and recorded on the title as a mortgage, sitting behind your bank’s first mortgage.

Priority between registered interests is set by the clock at the registry. Landgate’s guidance quotes the rule that instruments affecting the same interest “have priority as between each other according to the time of registration”. Your bank registered first, so it stays first; we’re recorded second. No ambiguity, no guesswork for the next conveyancer who reads the title.

For property in every state and territory outside Victoria, this is the structure we use. It’s usually arranged just as quickly as a caveat, and it lands on your title in the standard, familiar form. Our page on caveat loans outside Victoria explains the reasons in more depth.

How do the three compare side by side?

	Unregistered mortgage alone	Unregistered mortgage + caveat	Registered second mortgage
Shows on title search	No	Yes, as a caveat	Yes, as a mortgage
Lender’s interest	Equitable only	Equitable, protected by notice	Registered charge over the land
Where we use it	Never on its own	Victorian property	All other states and territories
Your bank’s first mortgage	Unchanged	Unchanged	Unchanged, still first
What happens at repayment	Nothing on title to remove	Withdrawal of caveat lodged	Release or discharge lodged

The first column is the one to be wary of. A lender relying on an unregistered mortgage with nothing on the title is exposed, and exposed lenders price and behave accordingly. We don’t lend that way.

Know your property’s state and roughly what you owe on it? That’s enough to start a quick enquiry and find out which structure applies.

Why use a caveat in Victoria and a registered mortgage elsewhere?

Because each one is the cleanest fit for the job in its location, and clean is fast.

In Victoria, the caveat-backed loan is well established for short-term business lending. Victoria moved to electronic lodgement early: Land Use Victoria’s bulletin confirms electronic lodgement became required for conveyancers, lawyers, banks and other subscribers from 1 August 2019, covering new mortgages and discharges, with caveats and withdrawals handled in the same digital environment. A Victorian caveat can be lodged and later withdrawn without paper changing hands.

Everywhere else, a short-term registered second mortgage is the better tool for you as the borrower:

• It’s the standard form. Every bank, conveyancer and registry in the country handles registered mortgages daily. Nobody needs to ask what it is.
• Your title tells a clear story. A buyer’s conveyancer or a refinancing lender sees a first and second mortgage, each with a payout figure, and settles them in order.
• Exit is routine. When you repay, a release is lodged and the mortgage comes off. No disputes about what the caveat protected.
• Speed is comparable. With electronic lodgement now the norm across the states, registering a mortgage doesn’t add days to the process.

You get the same outcome either way: business money against your equity, with your bank loan undisturbed. Our second mortgage page covers how that loan is sized and repaid.

A worked example: two owners, two states

Illustrative only — round numbers, no real people.

Two directors run a joinery business with a large commercial fit-out contract starting in three weeks. They need $180,000 for timber, hardware and a new edge-bander before the first progress claim is paid.

• Director A owns a house in Ballarat worth about $900,000 with $400,000 owing to the bank. A short-term caveat loan is written against the Victorian title: she signs the loan and mortgage documents, the caveat is lodged electronically, and the bank’s mortgage stays where it is.
• Director B owns a townhouse in Toowoomba worth about $750,000 with $300,000 owing. His security is a short-term registered second mortgage, lodged through the Queensland registry and recorded behind the bank.

Either property alone would carry the loan. The directors choose the Ballarat house because its equity is larger. Had they chosen Toowoomba, the timeline would have looked much the same. In both cases the exit is identical — the client’s progress payments over the following months, with the loan cleared as soon as the second claim lands. Short-term loans like this are measured in months, not decades.

What should you check before you borrow?

• Your title. Order a current search and look at what’s already registered or caveated.
• Your bank loan contract. Some first-mortgage agreements need the bank’s consent before you grant further security.
• Who owns the property. Every registered owner signs. If a trust or company owns it, see property in a trust or company.
• Your equity. Lenders look at the combined debt against the value; our page on how equity is calculated walks through the arithmetic.
• Your exit. A sale, a refinance, a contract payment or a tax refund — something real and dated.

Not sure which structure your property needs? Let’s sort it

You don’t have to work out the legal label before you call. Tell us where the property is and what’s owing, and we’ll tell you whether it’s a caveat or a registered second mortgage — and how quickly it’s possible to fund. Where everything lines up, $20k to $250k can be possible the same day, and larger amounts up to $5m possible within 24–48 hours.

The enquiry form takes about 60 seconds and there’s no credit check when you first enquire. Your details stay with us rather than being sent off to a queue of lenders, and a real person reads your answers and phones you. Please fill it in carefully — especially the property, the state it’s in and the date you need the money — because those three things decide the structure.
