Commercial Lease Dispute Guide for NSW Tenants

A shop can be trading well one month and facing a lease dispute the next. A rent review arrives that does not match expectations, a repair remains unfinished, or a landlord alleges a breach after a difficult period for the business. This commercial lease dispute guide outlines the practical steps NSW landlords and tenants can take to protect their position before a disagreement becomes a costly legal matter.

Commercial leases are not all governed in the same way. The terms of the signed lease, the nature of the premises, the tenant’s business, and whether the Retail Leases Act 1994 (NSW) applies can all affect the available options. Early advice can help you understand what the documents require and what a sensible resolution may look like.

Start with the lease, not the disagreement

When a dispute develops, it is tempting to focus on what was said in a phone call or who has acted unfairly. Those issues may matter, but the lease is usually the starting point. It records the rights and responsibilities both parties agreed to when the tenancy began.

Read the executed lease, any disclosure statement, variations, side letters, guarantees, notices and correspondence together. A later email agreement or an informal concession may alter how a clause operates in practice, particularly where one party has relied on it. Do not assume an arrangement is unenforceable simply because it was not set out in the original lease.

Pay close attention to the clauses dealing with rent, outgoings, repairs, maintenance, permitted use, insurance, options to renew, assignment, make-good obligations and default. The wording can be technical. For example, responsibility for repairs may depend on whether the problem concerns the building’s structure, the tenant’s fit-out, essential services or damage caused by a particular party.

A clear timeline is equally valuable. Record when the issue first arose, who was notified, what response was received, payments made, work completed and deadlines given. Keep copies of emails, letters, photographs, invoices and relevant text messages. Good records reduce uncertainty and provide a stronger foundation for negotiation or formal proceedings.

Common commercial lease disputes in NSW

Disputes often arise from ordinary business pressures rather than deliberate wrongdoing. Rent arrears and outgoings are common sources of tension, especially where invoices are unclear or an agreed rent concession has ended. A landlord may seek interest or enforcement action, while a tenant may question whether amounts were properly calculated under the lease.

Repair and maintenance disputes are also frequent. A tenant may say water leaks, electrical faults or air-conditioning problems are affecting trade. A landlord may consider the issue to be part of the tenant’s maintenance responsibility. The practical question is not merely who should pay. It is also whether the condition is making the premises unsafe, inaccessible or unsuitable for the permitted business use.

Other recurring issues include allegations of unauthorised use, disputes about fit-outs and signage, failure to exercise an option correctly, refusal of consent to an assignment or sublease, and make-good claims at the end of a lease. These matters can have significant financial consequences, particularly when a business needs to relocate or sell quickly.

Retail premises may have additional protections and procedures under NSW retail leasing legislation. However, whether a lease is covered depends on the circumstances. A warehouse, office, medical practice or mixed-use premises should not be assumed to fall inside or outside the retail leasing regime without checking the relevant facts.

Respond to a breach notice carefully

A notice alleging breach should never be ignored. It may set a deadline to remedy the alleged default, such as paying rent, repairing damage, ceasing a particular activity or supplying required information. Missing that deadline can increase the risk of termination action, claims for loss, or difficulty negotiating a workable outcome.

That does not mean you should immediately accept every allegation. Check whether the notice identifies the relevant lease clause, states the alleged breach with enough detail and gives a realistic opportunity to remedy it. Consider whether the amount claimed is correct, whether the obligation applies, and whether the other party has contributed to the problem.

Tenants should avoid withholding rent as a form of pressure unless they have obtained specific legal advice. Unpaid rent can create a separate breach, even where there is a genuine concern about repairs or access to the premises. Similarly, landlords should be cautious before changing locks, restricting access or taking possession of goods. Wrongful enforcement can create substantial legal exposure.

If time is short, acknowledge the notice in writing, state that you are reviewing it, and explain any immediate steps being taken. A measured response preserves options while the lease and facts are assessed.

Try to resolve the business problem early

Many lease disputes can be resolved through direct, documented negotiation. The best result is often one that keeps a viable tenant trading or allows a landlord to re-let the premises without a prolonged vacancy. That may involve a payment plan, temporary rent adjustment, agreed repair schedule, release from part of an obligation, consent to an assignment, or a negotiated exit.

The strength of your legal position matters, but commercial reality matters too. A tenant may have a sound complaint about access problems, yet still need a quick solution to protect cash flow. A landlord may be entitled to insist on strict compliance, but a practical agreement can be less expensive and disruptive than enforcement.

Put proposals in writing and be precise. Identify the amounts, dates, works, access arrangements and what will happen if the agreement is not met. If a concession is temporary, state when it ends. If the parties intend a settlement to resolve all claims, the document should say so clearly. Ambiguous agreements often create the next dispute.

Commercial lease dispute guide: when formal action is needed

Where direct discussion fails, the next step depends on the lease type and the issue. Retail lease disputes in NSW may need to go through mediation before proceedings can be commenced in the NSW Civil and Administrative Tribunal. Other commercial leasing disputes may be dealt with through negotiation, mediation, arbitration if the lease requires it, or court proceedings.

Formal action is not automatically the best choice. It can secure urgent orders or bring a dispute to a decision, but it also involves cost, time and uncertainty. A lawyer can assess the evidence, the value of the claim, the urgency of the situation and the likely forum before recommending a strategy.

Urgent advice is particularly sensible where termination is threatened, premises have been locked or access restricted, a business sale depends on lease assignment, or a tenant is about to vacate. Delays can affect bargaining power and may limit the remedies available.

Protect your position throughout the dispute

Professional communication makes a difference. Keep correspondence factual and avoid accusations you cannot prove. Continue meeting obligations that are not genuinely in dispute where possible, and do not make admissions simply to end an uncomfortable conversation.

For tenants, this may mean continuing to pay undisputed rent, seeking written consent before altering the premises, and arranging access for reasonable inspections or repairs. For landlords, it may mean providing clear statements of account, responding to repair reports promptly, and following the process required by the lease before taking enforcement steps.

Guarantees also deserve close attention. A director who signed a personal guarantee may remain exposed even if the tenant company is struggling or has ceased trading. Before agreeing to a surrender, assignment or settlement, all parties should understand who is released and who remains liable.
