How Our Commercial Lawyers Help Perth Businesses

Our Perth commercial lawyers provide end-to-end legal support across all stages of your business from startup through growth, expansion, and exit. Whether you need a single contract reviewed or ongoing commercial legal support, we tailor our services to your needs and budget.

Commercial Contracts & Agreements

In Perth’s contract-heavy business environment, the documents you sign determine whether you get paid and what happens when things go wrong. Our commercial lawyers draft, review, and negotiate service agreements, supplier contracts, subcontractor arrangements, joint venture agreements, and terms and conditions. We build contracts for WA’s commercial reality with appropriate variation clauses and enforceable payment terms. Before you sign any commercial contract, let us review it. The cost of a review is far less than the cost of a dispute.

Commercial Leases & Retail Tenancy

Whether you’re a landlord or tenant, commercial leases require careful attention. The terms you agree to will affect your business for years  rent increases, make-good obligations, and outgoings can significantly impact your bottom line. For retail tenants in Western Australia, we ensure compliance with the Commercial Tenancy (Retail Shops) Agreements Act 1985 (WA), including mandatory disclosure requirements and tenant protections that many landlords overlook. We handle lease negotiations, rent reviews, and SAT proceedings.

Business Structuring & Corporate Governance

Choosing the right business structure affects liability, taxation, asset protection, and future growth options. We advise on company formations, shareholder agreements, partnership structures, unit trusts, and corporate governance frameworks. Perth’s business landscape shifts constantly resource contractors acquire competitors during upswings, and professional firms restructure to bring in partners. For established businesses, we assist with restructures, director duties and obligations, ASIC compliance, and corporate governance under the Corporations Act 2001.

Intellectual Property Protection

Your brand, software, inventions, designs, and trade secrets are valuable business assets. Without proper protection, competitors can copy your work or exploit your innovations. Our commercial lawyers help Perth businesses protect IP through trademark registration, licensing agreements, confidentiality agreements, and IP assignment clauses in employment and contractor contracts. Whether you’re launching a new product or expanding into new markets, we ensure your intellectual property is secured before competitors can act.

Commercial Disputes & Litigation

Business disputes are inevitable. Suppliers fail to deliver, customers don’t pay, partners disagree. We represent Perth businesses in contract disputes, shareholder disputes, trade practices claims, and debt recovery matters. For retail tenancy disputes, WA’s State Administrative Tribunal (SAT) provides a streamlined resolution path. Our approach prioritises practical resolution through negotiation and mediation where possible, and through court proceedings when necessary. We assess each dispute honestly. If the cost of fighting exceeds recovery, we’ll tell you.

Debt Recovery Matters

Unpaid invoices affect your cash flow, planning, and ability to pay your own suppliers and staff. Our commercial lawyers help Perth businesses recover outstanding debts through formal demand letters, negotiated payment arrangements, statutory demands for company debtors, and Magistrates’ Court or District Court proceedings when required. We assess the debtor’s ability to pay before recommending action  there’s no point litigating if there’s nothing to recover. Fast, practical debt recovery for WA businesses.

John Zhang has been absolutely great in helping me with my EOI and application for a skilled visa in Australia. On both calls I've had with John, I have had a multitude of questions for him which he answered in depth and gave me all the information I required. He really has a great amount of knowledge and I would highly recommend him and the CMI legal team for their efficiency and professionalism.

I was very fortunate to have Tina TANG from CMI as my conveyancing solicitor for the recent sale of my property. She demonstrated exceptional professionalism and dedication throughout the entire process — from preparing the contract, exchanging contracts, right through to settlement. What impressed me the most is that even after settlement, she continued to go above and beyond to assist me as the vendor, making sure everything was properly taken care of.

Her diligence, patience, and attention to detail gave me great peace of mind and took away a lot of the stress of selling a property. I would highly recommend her to anyone looking for a reliable, professional, and truly supportive conveyancing solicitor. ⭐⭐⭐⭐⭐

We had the pleasure of working with Tina as our solicitor for our first home purchase, and we couldn’t have been in better hands. She carefully explained every step of the process, guiding us through what initially felt overwhelming and unfamiliar. Buying off the plan made us particularly cautious, especially when it came to reviewing legal documents. Tina’s meticulous approach put us at ease—she ensured we both clearly understood each aspect, taking the time to highlight and reorganise information to make it more accessible. Her dedication and professionalism made the entire experience far less daunting, and we’re truly grateful for her support.

I realised that I hadn’t left a review for my dealings with CMI legal. I had dealt with them a few months ago, but an epiphany made me come and leave a review.

5 stars is insufficient to express their work. We were working Dee and she is an amazing and thorough professional. She goes above and beyond and explains matters that makes you understand things really well. Thank you Dee for your amazing work.
