ASIC Search Before Filing a WA Court Claim — How to Verify the Right Entity

Filing your WA Magistrates Court claim against the wrong entity is one of the most common — and most avoidable — mistakes self-represented claimants make. If you sue "Mike's Plumbing" instead of "Michael Robert Smith" or "MRS Holdings Pty Ltd," your claim can be struck out. A ten-minute search before you file prevents weeks of wasted time.

Why Getting the Name Right Matters

Form 4 (Minor Case Claim) requires the defendant's exact legal name. The court uses that name to issue a sealed claim, and the claim must be served on that entity. If the name is wrong:

• The defendant can apply to have the claim set aside
• A default judgment obtained against a non-existent entity is unenforceable
• You may need to file a fresh claim (paying a second filing fee) against the correct party, while the limitation clock keeps running

"Mike's Plumbing" is a trading name — a label a business uses publicly. It is not a legal entity that can be sued. Behind that trading name sits either a natural person (a sole trader), a partnership, or a company. You need to find out which.

The Three Searches

1. ABN Lookup (Free)

Start at the Australian Business Register (abr.business.gov.au). Search by the business name, ABN, or ACN. The result tells you:

• The entity type (individual, partnership, company, trust)
• The ABN holder's name
• Whether the ABN is active
• The state of registration
• Any registered trading names

If the ABN holder is listed as "Michael Robert Smith" with a trading name of "Mike's Plumbing," your defendant is "Michael Robert Smith trading as Mike's Plumbing."

If the ABN holder is "MRS Holdings Pty Ltd," you are suing a company — and you need the ACN from the next search.

2. ASIC Company Register (Free Search, Paid Extract)

If the ABN lookup reveals a Pty Ltd company, go to the ASIC Connect search (connectonline.asic.gov.au). You can search by company name, ACN, or ABN.

The free search confirms:

• The exact registered company name
• The ACN (Australian Company Number)
• Whether the company is registered, deregistered, or under external administration

For your court claim, you need the company's registered office address — that is the address where legal documents are served on a company under section 109X of the Corporations Act 2001. To get this, you need to purchase a Current Company Extract ($10 online). The extract gives you:

• Registered office address
• Principal place of business
• Current directors and other officeholders (their residential addresses are not included)
• Share structure

If the company is deregistered, you cannot sue it while it is deregistered because it ceases to exist as a legal entity. Reinstatement may be possible through ASIC or a court; get legal advice about the available route.

3. ASIC Business Names Register

If you're dealing with a sole trader or partnership using a registered business name, the ABN Lookup should show the underlying entity. You can also search ASIC's national Business Names Register through ASIC Connect.

How to Name Each Type on Form 4

Always use the full legal name. If the company name includes "Pty Ltd" or "Ltd," include it. If there is an ACN, include it. Abbreviations and casual names invite problems.

Where to Serve a Company

Once you have the ASIC extract, you have the registered office address. Under section 109X of the Corporations Act 2001, you serve a company by posting the sealed claim via pre-paid ordinary post to its registered office address, or by personally delivering it to a director.

If the registered office is a virtual office or an accountant's address (common with small companies), you can still serve by post to that address — it counts as valid service regardless of whether the company actually checks that mailbox regularly.

What If the Business Has Closed?

If the sole trader has moved interstate, the company has been deregistered, or the partnership has dissolved, your claim gets more complicated:

• Sole trader moved interstate: you can still file in WA and serve interstate under the Service and Execution of Process Act 1992, with the extended 21-day response window and SEPA Form 1 notice.
• Deregistered company: the company must be reinstated before you can sue it. Depending on the circumstances, you may apply to ASIC or a court for reinstatement. This is beyond the scope of a minor case self-help process — consider Legal Aid WA (1300 650 579) for guidance.
• Dissolved partnership: sue the individual partners by name.

Do the Search Before You Write the Demand Letter

Don't wait until you are filling out Form 4. Run the ABN lookup and ASIC search before you write your letter of demand. The demand letter also needs the correct legal name and address, and sending it to the right entity strengthens your position if the matter goes to court.

The WA Minor Case Claim Guide includes a party identification worksheet that walks you through the ABN lookup, ASIC extract, and correct naming for each entity type — so you get the defendant right before you spend a dollar on filing fees.
