How To Create And Maintain A Unit Trust Register In Australia

If you run your business through a unit trust (or you’re thinking about setting one up), it’s easy to focus on the big-ticket items: the trust deed, the trustee, tax planning, and who holds what units.

But there’s a quieter admin task that can cause real headaches if you ignore it: keeping a unit trust register up to date.

A unit trust register is essentially your “source of truth” for unit ownership. It helps you track who the unitholders are, how many units they hold, when units were issued or transferred, and (where relevant under your deed and arrangements) what’s been paid for those units. When it’s maintained properly, it makes growth, succession planning, distributions, and funding much smoother. When it isn’t, it can create costly disputes, delays, and record-keeping problems.

Below, we’ll walk you through what a unit trust register is, why it matters, how to set it up, what to include, and how to maintain it over time-without drowning you in legal jargon.

What Is A Unit Trust Register (And Why Does It Matter)?

A unit trust register (sometimes called a register of unitholders) is a record of all units in a unit trust and who owns them.

In plain English: it’s the document that answers “who owns the trust (and in what proportions)?”

For small businesses, this matters because unit trusts are commonly used to:

• hold business assets (including intellectual property or equipment),
• operate trading businesses (depending on your broader structure),
• set out ownership between founders, family members, or investors, and
• manage distributions of trust income in proportion to unit holdings (if the trust deed is drafted that way).

Even though there isn’t a single “unit trust register law” in the same way companies maintain a share register under the Corporations Act, a register is still a key governance and record-keeping tool-especially where there is more than one unitholder, or where units can be issued or transferred over time.

When You’ll Actually Need It

You’ll usually rely on the unit trust register when you need to:

• confirm who is entitled to trust distributions (in line with the trust deed),
• help evidence ownership during a dispute or relationship breakdown,
• bring in a new investor or family member (issue new units),
• transfer ownership (transfer units),
• sell the business or conduct due diligence, or
• prepare clean records for your accountant and advisers.

It’s similar in purpose to a company’s share register, but tailored to unit trusts.

Unit Trust Register vs Trust Deed: What’s The Difference?

It’s common for business owners to assume the trust deed “covers everything.” Your trust deed is the governing document that sets the rules of the trust (including how units work, when they can be issued or transferred, what approvals are required, and how distributions can be made).

Your unit trust register is the practical record showing what has actually happened under those rules.

Think of it this way: the trust deed is the rulebook; the unit trust register is the scoreboard.

What Should Be Included In A Unit Trust Register?

There is no single “one size fits all” format, but a good unit trust register should be detailed enough that an independent person (for example, an accountant, buyer, or lawyer) can clearly understand the unit ownership position and key changes over time.

As a practical minimum, your unit trust register should include:

• Name of the unit trust (exactly as shown in the trust deed)
• Date the register was created (and version control if updated)
• Trustee details (name of trustee, and ACN if a corporate trustee)
• Total units on issue (and any different classes of units, if applicable)
• For each unitholder:
  • full legal name (individual or entity name),
  • address (and email if used for notices),
  • date they became a unitholder,
  • number of units held,
  • class of units (if relevant),
  • issue price / consideration (what they paid or contributed),
  • whether any amount remains unpaid (only if your trust deed and documentation allow for this kind of arrangement), and
  • date they ceased to be a unitholder (if they transferred out).

Recording Unit Transfers Properly

If units can be transferred (and many trust deeds allow this, subject to approval), your unit trust register should also show:

• the date of transfer,
• who the transferor was (the seller),
• who the transferee was (the buyer),
• the number of units transferred,
• any transfer price / consideration, and
• evidence of trustee approval (if your deed requires it).

In practice, you want a “paper trail” that lines up: trust deed requirements, transfer documentation, and the register update.

Do You Need Unit Certificates?

Some unit trusts issue unit certificates, and some don’t. Whether you should depends on your trust deed and your governance preferences.

Certificates can be useful as a practical record, but they don’t replace the unit trust register. If there’s ever a mismatch, what will matter depends on the facts and documentation (including the trust deed, trustee resolutions, transfer documents, and the register), so consistency across all records is important.

How To Create A Unit Trust Register: Step-By-Step

Creating a unit trust register doesn’t need to be complicated. What matters is that it is accurate, consistent with your trust deed, and maintained as your trust changes.

1. Confirm How Units Work Under Your Trust Deed

Before you create anything, start by reading the trust deed (or have your lawyer review it). You want to confirm:

• what “units” represent in your trust (and whether there are different classes),
• how units are issued (and whether trustee resolutions are required),
• how transfers work (consent, pre-emptive rights, restrictions), and
• what records the trustee must keep.

This step is crucial because your unit trust register should reflect the deed’s rules. If the deed requires trustee approval for transfers and you update the register without evidence of approval, you’re creating risk.

2. Choose A Format That’s Easy To Maintain

Most small businesses keep their unit trust register in a spreadsheet. That can work well if you apply strong version control and keep signed supporting documents.

Other businesses prefer a formal register document (for example, a PDF register with pages updated and signed when changes occur). Either approach can be fine-what matters is that the register is orderly and reliably updated.

3. Populate The Register With Initial Unit Holdings

If your unit trust was set up with initial unitholders (for example, you and a co-founder), record:

• the issue date (usually the establishment date or the date units were first issued),
• the number of units issued to each unitholder, and
• the consideration (what was paid or contributed for those units).

Be careful here: this is where mistakes often start. If you and a business partner verbally agreed on “50/50” but the register shows “70/30,” you’ve baked a dispute into your structure.

4. Create A Simple “Transaction Log” Section

Alongside the unitholder table, it’s helpful to add a transaction log showing each issuance, transfer, consolidation, or other unit change event in date order (but only include events your deed actually allows).

This makes your unit trust register much easier to audit later-particularly during due diligence if you sell the business.

5. Store Supporting Documents With The Register

Your register is strongest when you can back it up. Keep copies of:

• trustee resolutions approving issues or transfers,
• transfer forms or unit sale agreements (if applicable),
• any deeds of variation affecting unit rights, and
• evidence of payment or consideration (if relevant).

If you also have other entities in your structure (for example, a corporate trustee or a trading company), it’s a good idea to keep key governance records organised in the same place so you can find them quickly when needed.

How To Maintain A Unit Trust Register (So It Doesn’t Become A Mess)

A unit trust register is not a “set and forget” document. It should be treated as a living record that you update whenever anything changes.

If you want a simple rule: update the register immediately after any unit change. Leaving it for “end of year admin” is how errors creep in.

Update The Register When These Events Happen

Make sure you update your unit trust register whenever you have:

• Issue of new units (new investor, new family member, restructuring ownership)
• Transfer of units (sale between unitholders or to a third party)
• Any unit changes your deed permits (for example, redemption, cancellation, or consolidation-if allowed and properly documented)
• Change in unitholder details (name change, address change, entity restructure)
• Change in unit classes or rights (for example, via deed of variation)

Use Clear Governance Processes

Even small businesses benefit from a consistent process. For example:

1. You agree on the unit change (issue/transfer/other change).
2. You check the trust deed for required approvals and steps.
3. The trustee signs a resolution approving the change (if required).
4. The transfer/issue documentation is executed.
5. The unit trust register is updated.
6. All documents are stored together (register + supporting evidence).

This kind of process is particularly important if you have multiple owners or you’re bringing new people into the structure.

Keep Version Control (And A Single “Source Of Truth”)

Most register problems come from multiple versions floating around:

• one copy with your accountant,
• one on your laptop,
• one emailed months ago to a business partner, and
• one printed and filed that no one updated.

Pick one location (for example, a secure business drive), and adopt basic version control:

• date each version,
• track what changed,
• limit editing rights, and
• store signed approvals alongside it.

Be Careful With “Informal” Family Transfers

Many unit trusts are used in family businesses. It’s common for owners to want to “just move some units” to a spouse, child, or family trust.

Even when everyone is on good terms, these changes should still be documented properly. If you later sell the business, apply for finance, or face a dispute, unclear ownership records can cause delays and stress.

Also keep in mind that transfers and changes in unit ownership can have tax and duty implications depending on your circumstances. Make sure you get tailored advice before you restructure or transfer units.

Common Mistakes Small Businesses Make With Unit Trust Registers

Most unit trust register issues aren’t caused by bad intentions-they’re caused by busy people running a business and assuming “we’ll sort the paperwork later.”

Here are some of the most common pitfalls we see.

1. The Register Doesn’t Match The Trust Deed

For example, the trust deed may require trustee consent for transfers, but transfers are recorded in the unit trust register without any evidence of consent.

This is a red flag in due diligence and a risk in disputes.

2. No Record Of Consideration (What Was Paid)

Where units were issued or transferred, but there’s no record of what was paid (or whether it was a gift, loan, or capital contribution), you can end up with tax, accounting, and governance confusion.

3. Not Updating After “Small” Changes

Address changes, name changes, or a unitholder changing from an individual to a company/trust are often treated as minor admin.

But these details matter when you need to send notices, confirm entitlements (if applicable), or verify ownership for a bank or buyer.

4. Mixing Up Trust Ownership And Company Ownership

If you have a corporate trustee, it’s easy to assume “the company owns the trust.” In reality, the company is acting as trustee; ownership is recorded in the unit trust register (the unitholders), not in a company’s share register.

This is where clear documentation across your structure matters.

5. Poor Document Storage

If you can’t find the trustee resolutions, transfer documents, or executed variations that explain why the register changed, you’re relying on memory and goodwill.

That’s not where you want to be if the business grows, you bring in investors, or relationships change.

Key Takeaways

• A unit trust register is your core record of who owns units in your unit trust and how that ownership has changed over time.
• Your trust deed sets the rules, but the unit trust register shows what actually happened-so they should always align.
• A practical register includes unitholder details, units held, issue/transfer dates, consideration recorded, and a clear transaction history.
• Maintain your unit trust register by updating it immediately after any unit issue, transfer, or other change permitted by your deed, as well as any unitholder detail change.
• Clean record-keeping helps with distributions, disputes, finance, and due diligence if you sell or restructure your business.
