Since April 2016, married couples who own a HDB flat are not allowed to decouple. Currently, the Additional Buyer’s Stamp Duty (ABSD) of 20% is imposed on secondary home purchases for Singaporean Citizens. However, this does not apply in the case of an essential occupier.
Since essential occupiers are not considered homeowners, after they complete the Mandatory Occupation Period (MOP), they would be considered first-time property owners when purchasing a private property. The title of essential occupier also entitles one to take up a 75% loan on their next property, as opposed to the 45% limit imposed on individuals wishing to purchase their second property.
However, the individual designated as the essential occupier cannot use their CPF to fund the purchase of their HDB, because you are not an owner or beneficial owner of the HDB.
This means that if you are a young couple, you require careful consideration of your available funds. Furthermore, in any unfortunate circumstance of death without any estate planning, the Intestate Succession Act will take effect and you will be unable to dictate who you wish to leave your property to.
Mistake 1: Intestate Succession Act
For many, succession planning is a matter that many of us consider only as we approach our golden years. For those in the know, a lack of planning means that your assets will be subject to the Intestate Succession Act – a process of allocating your proceeds to your family members in the absence of a will.

The Intestate Succession Act prioritizes family members in accordance with 9 tiers, equally dividing your assets where required. Spouses are allocated first, followed by children, then the deceased’s parents.
In a scenario where a spouse has passed away without prior succession planning, the Intestate Succession Act may allocate a larger proportion of the property value to his children or his surviving spouse’s family. This may also be true where both parties pass away.
Fundamentally, a lack of succession planning may result in an allocation of your real estate assets which is not to your wishes due to the implications of the Intestate Succession Act. Other implications include leaving the estate to non-intended beneficiaries, non-financially mature individuals or ineligible beneficiaries. We recommend proper legacy planning for every possible scenario, and to consider the impact on any surviving family members as covered in the next point.
Mistake 2: Protection
Once again, if you have failed to plan ahead for any unfortunate circumstance, the Intestate Succession Act dictates your surviving family’s share of the assets and liabilities.
Your family members may be subject to any outstanding loans and mortgage payments on the property or any other asset – an untimely and unwanted burden. While purchasing insurance may add on to costs, we suggest the safest path forward in your pursuit.
Mistake 3: Ownership structure
In a typical manner of holding, ownership weightage can vary between 1/99 or 50/50. There is no secret formula here for the most optimal payment structure, but it would be natural to adopt the structure that maximises cash flow to that family unit.
You should weigh benefits and limitation of different ownership structures and calculate which weightage will offer the best cash flow outcome. This way, you can immediately minimise your cash outlay and the exiting party can focus on maximising funds for their next property purchase.
So, what plays the greatest role in determining the ownership structure?
Mistake 4: Usage of CPF
The ownership structure hinges considerably on the CPF contribution by either party in the initial purchase. This is because after selling your interest in the property, you are required to refund your CPF account with the principal and accrued interest in accordance with the CPF Housing Scheme.
For example, in the case of 99-1 In the decoupling process, one party exits and holds a minority share of the property, while the other party holds a majority share. For this discussion, let us assume that Sally is to hold this majority share of the property, and will be known as the ‘staying’ party.
When Sally purchases her husband’s share in the property, worth $1.0 million. She has to fork out 25% of this amount ($250,000) for her down payment and take a bank loan for the remaining 75% of the share ($750,000). On top of which, she has to incur stamp duty fees and legal fees associated with decoupling.
Her husband, George, ‘earns’ the proceeds of $1.0 million, but has to repay his initial CPF contribution (with accrued interest) that he had used to purchase the property with Sally, on top of his loan repayment. Hypothetically speaking, if the sum of his CPF contribution and loan repayment was greater than $1.0 million (plus the stamp duties and legal fees), the family unit would experience a net cash outflow.
Again, a point of consideration before exiting a property.
Mistake 5: Nationality of Spouse
Singapore’s increasingly globalised landscape; evident in the rise of international and intercultural unions—offers more than just rich cultural exchange; it can also confer tangible property-ownership advantages. While foreigners in Singapore ordinarily incur a 60 percent Additional Buyer’s Stamp Duty (ABSD) on residential acquisitions, bilateral Free Trade Agreements with Liechtenstein, Iceland, Norway, Switzerland and the United States extend the same concessionary ABSD treatment enjoyed by Singaporean citizens to nationals and permanent residents of these jurisdictions.
This nuanced benefit underscores how strategic cross-border alliances and policy frameworks intersect: by fostering closer ties with select treaty partners, Singapore enables certain foreign buyers to participate in its property market on nearly equal footing with locals. It’s a compelling illustration of globalisation’s practical implications, beyond mere economic theory.
Mistake 6: Difference in Value and Control
When you exit a property—by transferring your share—you relinquish all legal and beneficial ownership. That means you no longer have any right to:
• Vote on a sale or refinance
• Decide how proceeds are used
• Influence any management or upkeep decisions
Trying to dictate terms after you’ve left title risks running foul of ABSD rules and the “spirit” of honest ownership. 🚨
Best practice:
1. Make sure your exit is absolute – sign away control and avoid side-agreements that suggest ongoing influence.
2. Document your intentions in a clear will or trust so everyone knows you’ve fully stepped aside.
3. Seek independent legal advice to confirm there’s no lingering beneficial interest.
By spelling out that an ex-owner has zero say, you stay squarely within compliance and protect against any IRAS challenge.
Mistake 7: Added Financial Costs
The costs of decoupling go beyond CPF repayments and a transfer of share of ownership. Here are some costs that you may expect to encounter:
25% deposit
It would be impossible to conduct a decoupling if sufficient funds are not readily available to purchase 25% of your spouse’s stake.
Legal Fees
This is a standard added cost that must be included in your overall calculations
Stamp Duty
Do you have sufficient funds to negate these effects? Will it still be viable to purchase a property after incurring the stamp duties associated with decoupling?
CPF Refund
While this can be mitigated through varying the share of ownership between you and your spouse, careful calculations would have to be made to produce a desirable outcome. We recommend speaking to your mortgage advisor about this.
Loan Eligibility
The person who exits the initial property must be eligible for loans when attempting to purchase the second property. The staying party must also be eligible to take on added loans and mortgage payments when purchasing the remaining share of the initial property.
Wills, Trusts and added Insurance
These will demand added cash outlay, some of which may be recurring.
Mistake 8: The Process
Having a comprehensive understanding of the process will allow you to be more prepared for the road ahead. That way, decoupling will not be more of a hassle that thwarts your financial goals.
A typical process is as follows:
- Conduct a loan assessment for the buyer and seller (i.e., which party will be selling their share to the other)
- The valuation process
- Conveyancing
- Sales and Purchase agreement
- Financing and reassessment of bank loans
- Finalising insurance
- The decoupling and the subsequent search for second properties

We recommend an early consultation regarding financing and reassessment of bank loans to avoid incurring costs along the way only to be told that decoupling is not financially viable.
Mistake 9: Valuation
IRAS requires valuations to be based on arms-length transaction, regardless of whether the transaction occurs between related or non-related parties. In essence, the valuation of the property should reflect fair market value.
Nonetheless, there is some free play within the range of valuations deemed to be “fair market value”. Similar to our earlier discussion of how the ownership structure and weightage affects cash flows to the family unit, the valuation determines the amount a spouse would sell for that given share, affecting cash flows in a similar way.
One added consideration is that in isolation of ownership structure, selecting a higher valuation for the transaction would result in a higher gross amount paid in stamp duties. Deciding on your goals for decoupling, to minimize stamp duty payments or to maximize cash flows would play a role in deciding the right valuation for your transaction.
Mistake 10: Gifting
Some may ask: why go through the hassle of decoupling? Why not simply gift the property to my spouse, leaving me free to purchase another?
For one, gifting of property is still subject to buyer stamp duty and refund of CPF with accrued interest. Gifting the property to your spouse may render them ineligible to borrow against that asset in order to take on new loans for future property purchases.
In the same vein, gifting your property to your children does not mean that they could flip the home for cold hard cash the very next day.
Since the bankruptcy act was repealed by Insolvency Act in 2018, creditors now have 3 years to repossess gifted property even if it is not under your direct ownership. As such, your beneficiary would face difficulty in borrowing against that gifted property for a certain time frame, essentially locking up funds unnecessarily.
Conclusion
Decoupling is not a straightforward process and requires careful consideration of the processes and added costs involved. Even when all rational steps have been taken across documents and excel sheets, it is also important to plan for the worst-case scenario, to protect all that you have worked so hard to achieve!
