If you’ve ever switched lawyers in the middle of a matter or hit a speed bump over fees, you may have come across the term “solicitor’s lien.”
In simple terms, a solicitor’s lien is a legal right that lets a law firm hold your file or claim a portion of money recovered in your case until their reasonable costs are paid.
For small businesses and in-house teams, understanding how liens work can save time, money and stress. It can also help you plan for a smooth handover if you change firms, and resolve any fee disputes without derailing your underlying matter.
In this guide, we’ll cover what a solicitor’s lien is, the different types, when and how it can be used, the limits and ethics around liens, and practical ways to get a file released fast. We’ll also outline fee-security options you can consider upfront so you’re less likely to face a lien in the first place.
What Is A Solicitor’s Lien In Australia?
A solicitor’s lien is a security right. It doesn’t decide what you owe, but it gives the lawyer leverage to secure payment of proper, outstanding legal fees and disbursements.
In Australia, there are two main categories:
- Retaining lien – a right to hold documents or property already in the lawyer’s possession until costs are paid.
- Charging lien – a right to have unpaid costs paid out of money or property you recover in the matter (often called the “fruits of litigation”).
Both are constrained by professional conduct rules and, importantly, by the court’s power to ensure fairness and keep cases moving. A lien is not a green light for unreasonable fees. If costs are disputed, there are processes in each state and territory (such as costs assessment, taxation or review) to work out what’s fair.
Types Of Solicitors’ Liens (And What They Cover)
Retaining Lien: Holding The File
A retaining lien allows the outgoing firm to hold onto your matter file and other property they already possess until proper fees and disbursements are paid.
It’s “passive.” A firm can keep what it has, but can’t sell it or otherwise enforce it like a mortgage. The pressure is practical: you or your new firm may need the file to meet deadlines or keep the matter progressing, so security is negotiated to enable release.
Typically, a retaining lien can cover:
- Correspondence, internal notes, draft pleadings and work product generated during the retainer.
- Documents supplied by you that are now integrated into the working file.
- Other property in the firm’s possession where the firm has a right to hold it (for example, certain originals kept for safekeeping).
There are limits. Documents with independent value that you need to function (think passports, certificates of title, trust deeds or key corporate records) often must be released promptly, with substitute security in place so the firm’s costs are still protected. Courts and professional rules generally support that balance.
Charging Lien: The Fruits Of Litigation
A charging lien gives a lawyer an equitable right to be paid from the money or property recovered as a result of their work in a proceeding (for example, a settlement sum, judgment proceeds or specific property obtained in the matter).
To protect the lien, the firm will usually notify you, the other party and, where appropriate, the court that costs are claimed from any recoveries. Courts can then make orders to preserve the fund, require amounts to be held in trust, and supervise distribution so reasonable unpaid costs are accounted for without unfairly prejudicing you.
When Can A Lien Be Used (And What Are The Limits)?
Liens should be exercised for proper, outstanding costs only, and in a way that’s proportionate and consistent with professional obligations. There are also jurisdictional nuances across Australia you should be aware of.
Common Triggers
- Unpaid invoices: The usual trigger is a bill that’s due and unpaid. If the amount is disputed, firms and clients often agree to hold an amount in trust (or provide another form of security) so the file can be released while the dispute is resolved.
- End of a retainer: Liens most often arise when a client terminates a retainer or a firm ceases to act. The file handover is where practical issues-and solutions-show up.
- Clear notice: The outgoing firm should communicate that it asserts a lien, identify what’s owed (or disputed), and state the security that will satisfy release.
What Can Be Held-And What Must Be Released?
- Working files: Drafts, correspondence, briefs and internal work product can generally be held under a retaining lien.
- Documents with independent value: Passports, certificates of title, trust deeds and similar items usually need to be released promptly, subject to substitute security (for example, an undertaking or funds held in trust) so the lien isn’t lost.
- Trust money: Money in a lawyer’s trust account is strictly regulated under trust accounting rules. A lien cannot be used to override those rules. Use of trust funds remains subject to the governing legislation, rules and, where applicable, court orders.
Court Supervision And Jurisdictional Differences
Australian courts have inherent power to supervise liens and prevent unfair prejudice. While the core principles are similar nationwide, the pathways to resolve fee disputes and the terminology can differ under the Legal Profession Uniform Law (in NSW and Victoria) or equivalent legislation in other states and territories.
Common court-managed outcomes include:
- Ordering delivery of the file to the new solicitor on the basis of undertakings that protect the outgoing firm’s costs interest.
- Directing that disputed fees go to assessment/taxation and that funds be held in trust pending the outcome.
- Restricting use of liens where they would unduly delay proceedings or harm the administration of justice.
Bottom line: a lien is real, but not absolute. Courts will balance your right to keep your matter moving with the lawyer’s legitimate interest in being paid fairly.
Charging Liens In Practice
To exercise a charging lien, a firm typically gives prompt written notice to you, the opposing party and, if appropriate, the court before funds are distributed. Practical steps can include:
- Placing the disputed portion of a settlement or judgment into a controlled trust account.
- Seeking directions recognising the lien and governing how the funds will be released.
- Ensuring undisputed amounts are paid out to you while the reasonable costs issue is resolved.
Ethical Constraints: Security, Guarantees And Conflicts
It’s common for firms and clients to agree on security for fees, but there are ethical guardrails. These exist to prevent conflicts, undue influence and unfair terms-especially where there is an imbalance of power or urgent time pressure.
Taking Security Over Assets
Some matters (particularly corporate or commercial work) may involve a firm asking for security over assets. If you agree to grant a security interest, it should be clearly documented, proportionate to the exposure and properly registered. For example, a business client might offer a tailored General Security Agreement, with the firm then taking steps to register on the PPSR or arrange to register the security interest in a timely way.
Even where security is appropriate, lawyers must avoid any arrangement that is unconscionable or conflicts with their duties. If you’re asked to give security, it’s reasonable to request time to consider it and, if needed, obtain independent advice.
Personal Guarantees And Payment Instruments
In some cases, a director or individual may be asked to back a company’s obligation. If a firm suggests a guarantee, make sure the document is transparent and fairly limited in scope. You should also consider independent advice regarding personal guarantees before signing.
For simple fee arrangements, a short-form promise to pay can be documented without security-this is sometimes done using a promissory note. Again, make sure the terms are clear (amount, timing, interest if any, and what happens on default). If you prefer to formalise the agreement as a deed rather than a contract, ensure the deed execution formalities are met.
How To Get A File Released Quickly (Without Compromising Your Position)
If you’re changing firms or you’re in-house trying to keep a matter on track, you don’t have to stay stuck. There are practical, well-accepted ways to resolve a lien fast.
1) Agree Interim Security So The File Can Move
Often the fastest pathway is agreeing to hold a sum in trust or provide another form of security while fees are negotiated or assessed. This can be recorded in a short agreement or formalised using a Deed of Release and Settlement where you’re resolving a broader costs dispute.
2) Use Solicitors’ Undertakings Between Firms
Courts and the profession place significant weight on undertakings. The incoming firm can undertake to protect the outgoing firm’s costs interest, hold disputed amounts in trust and not release settlement funds until costs are resolved. To streamline communications and authorise the new firm to liaise and receive the file, it’s good practice to put an Authority to Act in place.
3) Negotiate, Then Use Costs Assessment If Needed
Costs disputes are commonly resolved by negotiation (for example, agreeing a fixed amount). If that fails, the dispute can be referred to the relevant state or territory process (costs assessment, taxation or review). While that runs, the file usually moves under undertakings or with funds held in trust so your matter isn’t delayed.
4) Seek Court Directions Where Cooperation Breaks Down
If you can’t reach agreement, the court can cut through the deadlock. Typical orders include delivery of the file on undertakings, payment of disputed sums into a controlled account and a timetable for costs determination-all designed to keep your case moving while fairly protecting the outgoing firm’s interest in payment.
How To Reduce The Risk Of A Lien In The First Place
Prevention is better than cure. A few practical steps at the start of a retainer can minimise the chance of a lien interrupting your matter later.
Set Clear Expectations Upfront
- Engagement letter and scope: Make sure the scope of work, billing method and likely timelines are set out clearly.
- Reasonable retainer on trust: Agree a sensible initial retainer that reflects the early work expected.
- Staged billing and transparency: Regular, clear invoices reduce surprises and disputes.
Consider Appropriate, Proportionate Security (Where Justified)
In higher-risk or longer-running matters, proportionate security can give both sides confidence. This might include a tailored General Security Agreement (for corporate clients) that’s registered on the PPSR, or a very limited guarantee. If you do opt for security, ensure the terms are tight, the amount is proportionate and you understand the implications before signing.
If you later change firms, having transparent arrangements from day one usually makes it easier to agree on a quick handover without needing to test lien rights.
Use Simple, Workable Payment Plans
Where cash flow is tight, a short, written plan can avoid escalation. If the arrangement needs extra formality, you could record the commitment to pay in a short deed or arrange to register the security interest where that’s part of the agreement. If a firm seeks a director backstop, ensure any personal guarantees are appropriately limited and you’ve considered independent advice.
Key Takeaways
- A solicitor’s lien is a lawful security right that can hold a file (retaining lien) or reserve part of a recovery (charging lien) until reasonable unpaid costs are resolved.
- Liens are bounded by ethics and court supervision. Courts can order file release on undertakings or require money to be held in trust so your matter keeps moving while costs are worked out.
- Not everything can be held. Documents with independent value (like passports, titles or trust deeds) usually must be released promptly, often with substitute security.
- Practical solutions include interim security, solicitors’ undertakings, negotiation and costs assessment. If cooperation stalls, the court can direct a fair, efficient path forward.
- To reduce lien risk, set clear billing expectations, consider proportionate security where justified (such as a properly documented and registered General Security Agreement on the PPSR), and avoid open-ended obligations without clarity.
- If you settle a costs dispute, formalise the outcome-this might be via a short deed or a Deed of Release and Settlement-so everyone can move on with certainty.
