What it means
A lien turns an ordinary unsecured debt into a claim on a specific asset. It is recorded in the public property register, so any buyer, lender or title insurer searching the record will find it, and that visibility is what gives the lien its force.
The owner keeps the house, but cannot pass clean title until the claim is dealt with. Liens are ranked, and rank decides who gets paid.
Statutory liens for unpaid property taxes usually sit ahead of everything, the first mortgage comes next, and later mortgages, mechanics liens for building work and judgment liens follow in the order they were recorded. A claim that ranks below the sale proceeds recovers nothing, which is why priority matters more than the size of the debt.
Some liens are voluntary and some are not. A mortgage is voluntary because the owner signs up to it in exchange for the loan; a tax lien or a mechanics lien filed by an unpaid roofer is involuntary and arrives without consent.
Involuntary liens are the ones that surprise people, because the first sign is often a failed sale rather than a letter. For business owners the connection is direct.
Personal guarantees on business borrowing, unpaid business taxes and court judgments against a sole trader can all end up secured against the family home, which converts a company problem into a household one. Removing a lien takes a release, a formal document filed by the claimant confirming payment, or a court order in a contested case.
Owners are often surprised that paying the debt is not enough on its own, because a lien that is never formally released will still show up on a title search years later.
In practice
Real-world examples.
Example
A homeowner hires a builder for a $34,000 extension, disputes the final invoice and withholds payment. The builder files a mechanics lien, and the dispute only surfaces two years later when a refinancing application is refused because the title search shows the outstanding claim.
Example
A sole trader falls behind on payroll taxes for her cleaning company. The tax authority records a lien against her home for $47,000, and because statutory tax liens rank ahead of her second mortgage, the second lender freezes her drawdown facility.
Example
A couple agree a sale at $610,000 and discover an old $9,000 judgment lien from a former business partner that was paid but never released. Completion is delayed six weeks while the solicitor tracks down the creditor and obtains the release document.
Formula
Calculation
Net proceeds to owner = sale price - selling costs - liens in order of priority, until proceeds run out
A house sells for $520,000. Selling costs, mainly agent commission and legal fees, run to 6% of the price. Registered claims are a property tax lien of $12,000, a first mortgage of $300,000, and a mechanics lien of $28,000 filed by a contractor after the mortgage was recorded.
Selling costs = $520,000 x 6% = $31,200
After selling costs: $520,000 - $31,200 = $488,800
Less property tax lien: $488,800 - $12,000 = $476,800
Less first mortgage: $476,800 - $300,000 = $176,800
Less mechanics lien: $176,800 - $28,000 = $148,800
Net to the owner = $148,800. Now assume the market falls and the same house sells for $360,000 with the same 6% costs. Selling costs are $21,600, leaving $338,400. After the $12,000 tax lien and the $300,000 mortgage, $26,400 remains, so the contractor recovers $26,400 of the $28,000 owed and the owner receives nothing.Case study
Seen in the real world.
The following is an illustrative and fictional scenario. Barrowfield Joinery, an invented cabinet-making firm, was owned by a couple who had personally guaranteed a $180,000 equipment loan. When a large hotel contract was cancelled and the firm could not pay, the lender obtained judgment and recorded a lien against the couple's home, which was worth about $470,000 and carried a $250,000 mortgage.
The couple had planned to sell the house, move somewhere smaller and use the difference to restart on a reduced scale. The lien meant that after 6% selling costs of $28,200, the $250,000 mortgage and the $180,000 judgment, only $11,800 would remain from a $470,000 sale, which was not enough to fund the move.
They negotiated a settlement of $120,000 with the lender, payable from the sale, in exchange for a release of the lien, which left $71,800. The illustrative lesson is that a personal guarantee signed years earlier had quietly attached itself to the home, and the couple only discovered its practical effect when they tried to sell.
Watch out
Common mistakes.
- Assuming a lien only matters at sale. It also blocks refinancing, affects credit assessments and can accrue interest and enforcement costs while it sits on the register.
- Thinking the largest debt gets paid first. Payment follows recorded priority, so a small tax lien can outrank a large mortgage entirely.
- Paying the debt and moving on without checking the register. The lien remains visible until the claimant files a formal release, and chasing it years later is much harder.
Questions
People also ask.
Can a lien be placed on a home without the owner agreeing?
Yes, tax authorities, courts and in many places unpaid contractors can record involuntary liens without consent.
Does a lien force a sale?
Not usually by itself, though some lienholders can start foreclosure proceedings, and most simply wait for a voluntary sale or refinancing.
How do I find out what liens exist on a property?
A title search at the relevant land or property register lists recorded claims, and a title insurer or conveyancer will run one as standard.
