They Held It 50-50 to Keep Their Options Open. Two Children Now Own a Quarter of the Home.

The question takes about thirty seconds at the conveyancing lawyer's office, usually near the end, usually when everyone is tired. Joint tenancy or tenancy-in-common? Most couples have never heard the words before that morning. Many pick tenancy-in-common because someone has told them it keeps the decoupling option open, which is true, and because 50-50 sounds fair, which is also true.

It is the highest-stakes box on the form. This is what it decides.

Shaun and Wei-Ling are an illustrative composite, not real clients. The assumptions are stated and every figure below is computed from them.

The facts

Shaun, 44, and Wei-Ling, 41, both Singapore citizens, bought a private condominium in February 2021 for S$1,600,000. They borrowed 75% — S$1,200,000 over 30 years, at an assumed 1.90%, an instalment of S$4,376 a month. Five years in, the outstanding balance is about S$1,044,000. Assume the property is worth S$1,850,000 today, a 15.6% gain on purchase.

They held it as tenants-in-common in equal shares. The reason was deliberate: they intended to decouple in a few years, transferring his half to her or hers to him, so that one of them could buy an investment property free of Additional Buyer's Stamp Duty. Holding as tenants-in-common preserves that route. We have walked through that arithmetic before, and on its own terms the choice was sound.

Shaun died in February 2026. He did not leave a will. Their children are nine and six.

What the two manners of holding actually do

Joint tenancy means the co-owners together own the whole. On the death of one, the right of survivorship operates: their interest passes automatically to the surviving owner. It does not enter the estate. It is not distributed by a will — survivorship beats a will, and a will leaving "my half of the house" to somebody else has nothing to operate on. In practice the survivor registers a notice of death and the title is theirs.

Tenancy-in-common means each owner holds a separate, defined share. There is no survivorship. The share is part of the deceased's estate and passes under their will, or — if there is no will — under the Intestate Succession Act 1967.

The Act is short and it does not consider your intentions. Rule 1: a surviving spouse with no children and no surviving parent takes the whole estate. Rule 2: where there is a surviving spouse and children, the spouse takes one-half and the children share the other half equally. (The Act does not apply to Muslim estates, which are governed separately.)

So Shaun's 50% of the home divides:

Wei-Ling now owns 75% of the home she lives in. Her children own 25% of it. Nobody intended this. The form did it.

Minors on a title are not a paperwork problem

This is where it stops being an accounting exercise. Had Shaun left a will giving his half to Wei-Ling, the estate would need a grant of probate — a delay and a cost, but a clean one. Without a will, the family needs Letters of Administration, and the presence of minor beneficiaries changes the application in specific ways.

Where a beneficiary is a minor, the court will normally require at least two administrators or a trust corporation, rather than allowing the surviving spouse to administer alone. Sureties may be required, and an application to dispense with them is a separate step with its own cost. Practitioners quote uncontested Letters of Administration in the region of S$1,000 for a straightforward estate; estates involving minors are routinely quoted in the thousands and can run well beyond that.

The harder constraint is what it does to the asset. Wei-Ling cannot simply sell the home and move somewhere smaller. A quarter of it belongs to two children who cannot give title, cannot consent, and whose interests the administrators are obliged to protect. Any sale has to be justified as being in their interest and the proceeds of their share held for them, not spent on the next home. The practical answer is often: you do not move until the younger one turns 21. That is fifteen years.

A will costs a few hundred dollars and would have removed all of it.

The plan the 50-50 existed to serve is the thing it destroyed

The 50-50 split was chosen so that one of them could later hold nothing and buy fresh. Consider where Wei-Ling now stands.

She owns 75% of a residential property. For ABSD counting, any share counts as owning a property, so her next purchase is a second property. On a S$1,500,000 home that is S$44,600 of Buyer's Stamp Duty plus 20% ABSD — S$344,600, against S$44,600 had she owned nothing. On S$2,000,000 it is S$469,600 against S$69,600.

Nor can she quietly tidy the title. Buying the children's 25% is a purchase: at S$462,500 it attracts S$8,475 of Buyer's Stamp Duty, and it needs the administrators to sell their wards' interest to the administrator herself — a conflict the court looks at closely. The clean option she thought she had bought no longer exists.

And there is a trap in the opposite direction worth knowing. If a couple holds as joint tenants and one of them later wants to convert, a joint tenant can sever unilaterally under section 53(5) of the Land Titles Act by registering a declaration and serving it on the other. But a severance that way produces a tenancy-in-common in equal shares only. You cannot unilaterally manufacture a 99-1. A 99-1 requires a transfer, and a transfer has its own duty — and IRAS has assessed 99-1 arrangements entered into purely to reduce ABSD as tax avoidance.

The mortgage does not pause

Because this is private property, the Home Protection Scheme does not apply. HPS covers HDB and DBSS flats. It does not cover condominiums or executive condominiums. Mortgage-reducing cover on a private home is optional, bought commercially, and the family either has it or does not.

Without it, the S$1,044,000 outstanding continues. The instalment of S$4,376 a month now sits on one income, and at a 55% Total Debt Servicing Ratio it needs gross monthly income of about S$7,956 on its own, before any other commitment. That is the number to check against the household's actual position before a death, not after one.

A will does not cover CPF. A CPF nomination does not cover your home.

This is the sentence most worth carrying away, and it catches careful people.

CPF savings are not part of your estate. They pass under your CPF nomination, and if you have not made one they are distributed by the Public Trustee under intestacy rules. Your will has no effect on them.

Property is the mirror image. Your CPF nomination has no effect on your home. And the CPF that went into the property is not refunded on death — it stays in the property, and the refund of principal plus accrued interest only crystallises when the property is sold, which is exactly the event the children's interest has now made difficult.

Two documents, two separate jobs. Most people have one of them, and often neither.

What to actually do

None of this is legal advice, and a fifteen-minute conversation with a lawyer would settle it for your own facts. But four checks are worth making this week.

Find out how you hold your property. It is on the title and your conveyancing lawyer has it. A surprising number of owners are certain they are joint tenants and are not.

If you are tenants-in-common, write a will. That is the whole fix for the worst part of this. The manner of holding can stay exactly as it is, decoupling stays available, and the intestacy split never happens.

If you are joint tenants, understand what survivorship overrides. It is a powerful default and a blunt one. It moves the property to the co-owner regardless of what your will says, which is right for most couples and wrong for some — second marriages and blended families in particular.

Check the mortgage cover separately. HPS is automatic for most HDB owners and absent for every private one. The question is not whether the family inherits the home. It is whether they can keep paying for it.

The choice between joint tenancy and tenancy-in-common is not about tax. It is about who owns the roof the morning after. Make it on purpose.
