Every S-REIT you can buy on the SGX exists legally only because of a single foundational document that most investors never actually read.
A REIT trust deed is the legal document that constitutes a Singapore REIT as a trust, setting out the rights and duties of the REIT manager, the trustee, and unitholders, along with the fund’s investment mandate, borrowing limits and distribution policy.

Key Takeaways
- Every S-REIT is legally structured as a trust, created and governed by its trust deed, not as a company under the Companies Act.
- The trust deed defines the roles of two separate parties: the REIT manager, who runs day-to-day operations, and the trustee, who holds legal title to the assets on behalf of unitholders.
- MAS’s Code on Collective Investment Schemes sets a regulatory gearing (leverage) limit of 50% of total assets for all S-REITs, which trust deeds must also respect.
- Trust deeds specify the REIT’s investment mandate — for example, restricting a REIT to industrial, retail, or diversified property types.
- Amending a trust deed generally requires unitholder approval at a general meeting, giving investors some say over major structural changes.
What Is a REIT Trust Deed?
Unlike an ordinary listed company, which is incorporated under the Companies Act, a Singapore REIT is a unit trust — a legal structure created by a trust deed rather than a company constitution. The trust deed is negotiated between the REIT’s sponsor and a licensed trustee (commonly a bank-affiliated trustee such as DBS Trustee, HSBC Institutional Trust Services, or Perpetual (Asia)) at the time the REIT is set up, typically ahead of its IPO, and registered with the Monetary Authority of Singapore (MAS).
The deed is the ultimate rulebook for the REIT: it appoints the REIT manager to run daily operations and make investment decisions, while the trustee holds legal title to the underlying properties on behalf of unitholders and acts as a check on the manager’s conduct. This separation of powers — manager runs the business, trustee holds the assets and safeguards unitholders — is a defining feature of the S-REIT structure and distinguishes it from how an ordinary company is governed by its board alone.
How Does It Work in Singapore?
A typical REIT trust deed covers several categories of provisions that directly affect what investors can expect from the REIT.
| Provision | What It Covers |
|---|---|
| Investment mandate | Permitted property types and geographies (e.g. Singapore industrial, pan-Asian retail) |
| Gearing limit | Maximum borrowing, capped at 50% of total assets under MAS’s Code on Collective Investment Schemes |
| Manager’s powers and fees | Base fee, performance fee structure, and scope of the manager’s authority |
| Trustee’s duties | Safekeeping of assets, oversight of the manager, and enforcement of unitholder rights |
| Distribution policy | How and when income is distributed to unitholders |
| Amendment process | Requires unitholder approval at an extraordinary general meeting for most material changes |
Because the trust deed sets the gearing limit and investment mandate, it directly shapes the risk profile investors are exposed to. A REIT cannot simply decide to borrow beyond the regulatory cap or expand into an entirely new property sector without the deed itself (and often unitholder approval) permitting that shift.
a REIT Trust Deed Example
A Singapore-listed industrial S-REIT’s trust deed restricts its investment mandate to industrial and logistics properties, and sets its gearing limit at the regulatory maximum of 50% of total assets. When the REIT manager proposes acquiring a data centre — a different asset class — this falls within the deed’s broader ‘industrial’ definition and can proceed under the manager’s existing authority. However, when the same manager later proposes raising the REIT’s target gearing policy closer to the 50% ceiling to fund a large acquisition, this requires clear disclosure to unitholders, since it materially changes the REIT’s risk profile even though it remains within the deed’s stated limit.
Advantages of a REIT Trust Deed
- Legal separation of powers. Having a manager and an independent trustee creates a built-in check against a manager acting solely in its own interest.
- Defined risk boundaries. Investment mandate and gearing limits in the deed prevent a REIT from drifting into unrelated, riskier asset classes without unitholder input.
- Regulatory alignment. Trust deeds are drafted to comply with MAS’s Code on Collective Investment Schemes, giving investors a baseline level of regulatory protection.
- Unitholder voting rights on major changes. Material amendments to the deed generally require unitholder approval, giving investors a voice in structural changes.
Risks and Limitations
- Most retail investors never read the trust deed itself, relying instead on summaries in the prospectus or annual report.
- Fee structures embedded in the deed (base and performance fees) can incentivise a manager to pursue growth through acquisitions and equity raises rather than purely maximising per-unit returns.
- Gearing limits can still allow REITs to operate close to the regulatory ceiling, leaving less headroom during a downturn.
- Investment mandate definitions can sometimes be broad enough to permit expansion into adjacent but riskier property types.
- Amendments requiring unitholder approval can still pass with a simple majority, meaning smaller unitholders may be outvoted by larger ones.
REIT Manager vs Trustee: Roles Under the Trust Deed
| Role | REIT Manager | Trustee |
|---|---|---|
| Main responsibility | Day-to-day operations, acquisitions, leasing strategy | Holding legal title to assets, safeguarding unitholder interests |
| Compensation | Base fee + performance/acquisition fees | Trustee fee, typically a smaller, fixed percentage of asset value |
| Who appoints them | Typically the REIT’s sponsor, at IPO | Appointed under the trust deed, approved by MAS |
| Removal | Can be removed by unitholder vote per the deed’s terms | Can be replaced, subject to the deed’s replacement provisions |

The Bottom Line
The trust deed is the constitutional document behind every S-REIT, setting the gearing limits, investment mandate and manager-trustee checks-and-balances that ultimately shape the risk and return an investor experiences — even though few unitholders ever read it in full.
Frequently Asked Questions
What is a REIT trust deed?
It is the legal document that constitutes a Singapore REIT as a trust, defining the roles of the manager and trustee, the investment mandate, gearing limits, and distribution policy.

No. A REIT is structured as a unit trust under a trust deed, not as a company incorporated under the Companies Act.
What is the maximum gearing limit set for S-REITs?
MAS’s Code on Collective Investment Schemes caps S-REIT gearing at 50% of total assets, a limit that trust deeds must also respect.
Who enforces a REIT trust deed?
The trustee is responsible for holding the REIT’s assets and overseeing the manager’s compliance with the trust deed, subject to MAS regulation.
Can a REIT trust deed be changed?
Yes, but material amendments generally require unitholder approval at an extraordinary general meeting.
