Cohabitation in Singapore carries no legal status of its own. There is no common law marriage here, however long you have lived together, so on separation there is no division of matrimonial assets and no spousal maintenance. What you have instead is ordinary property law, and whatever you wrote down.
I’m Wahab. I run A.W. Law LLC in Chinatown, and the version of this conversation I dislike having is the one after twelve years and a joint mortgage, when someone finds out that the law never treated them as a couple at all. None of what follows is a reason to marry. It is a reason to put a few documents in place.
There is no common law marriage
A marriage in Singapore exists because it was solemnised and registered. The Women’s Charter 1961 deals with solemnisation in Part 3 and registration in Part 4, and section 33 sets out the legal effect of that registration. Muslim couples marry under the Administration of Muslim Law Act 1966 and register at the Registry of Muslim Marriages.
Nothing else counts. Not a long tenancy in both names, not a religious ceremony without registration, not children, not a decade of shared bills. The phrase “common law wife” gets used in Singapore because people have heard it on British television. It has no legal meaning here and it never has.
What married couples get and you do not
The gap is easiest to see side by side.
| On separation | Married couple | Unmarried couple |
|---|---|---|
| Division of the home and savings | Section 112, Women’s Charter: the court divides matrimonial assets on a just and equitable basis | No such power. Ownership follows property law |
| Maintenance for the partner | Available to a wife or an incapacitated husband under the Women’s Charter | Not available at all |
| CPF and pension adjustments | Can form part of the section 112 exercise | Outside the court’s reach |
| Maintenance for the children | Sections 68 and 69, Women’s Charter | Sections 68 and 69, Women’s Charter, identically |
| Custody, care and control, access | Women’s Charter or the Guardianship of Infants Act 1934 | Guardianship of Infants Act 1934 |
Read the last two rows again. Children are the one area where marriage makes almost no difference. Everything above them is where it makes all of it.
How the property question is actually decided
Without section 112, a home is resolved the way any other property dispute is: by asking who owns what in equity.
Start with the title. Joint tenancy means the survivor takes the whole property automatically on death, outside the will. Tenancy in common means each of you holds a defined share, and that share passes under your will or on intestacy. Most couples I ask cannot tell me which one they have. Your title search will say, and it takes minutes to check.
Where the legal title does not match what each person actually put in, the arguments are resulting trust and common intention constructive trust. The Court of Appeal set out the framework in Chan Yuen Lan v See Fong Mun [2014] SGCA 36. In broad terms the starting point is that beneficial interest follows the parties’ contributions to the purchase price, and that presumption can be displaced by evidence of a different common intention.
What that means in a kitchen table sense: bank transfers, CPF statements and the deposit trail carry real weight. Paying the utilities, buying the furniture and doing the renovation are much harder to convert into a share of the flat. If you funded a property in your partner’s name and you have nothing in writing, get advice before you move out, not after. Our property disputes page covers how these claims are run.
Children do not depend on marriage
Section 68 of the Women’s Charter places the duty to maintain a child on a parent. Section 69 lets the Family Justice Courts order that maintenance. Neither turns on whether the parents were married, so an unmarried mother can apply against the father and an unmarried father can be ordered to pay, on the same footing as anyone else. The amount is worked out the same way it would be for a married couple: the child’s reasonable needs, set against each parent’s means.
Custody, care and control and access for a child born outside marriage run through the Guardianship of Infants Act 1934. Section 3 makes the child’s welfare the paramount consideration, section 5 gives the court power to make, discharge or amend custody and maintenance orders, and section 5A deals with enforcing an access order.
The practical bottleneck is paternity. Where the parents are not married, the father’s position is not assumed, and establishing it is usually the first piece of work rather than an afterthought. We deal with that on the paternity page, and in more detail in our guide to an unmarried father’s rights.
One more thing worth knowing: under the Legitimacy Act 1934, a child born outside marriage is legitimated by the subsequent marriage of the parents, and section 10 gives an illegitimate child and that child’s mother rights to succeed on each other’s intestacy. The father is not in that section. If you want your child to inherit from you, write a will.
HDB rules for unmarried couples
HDB’s family schemes are built on marriage or an intention to marry. The couples and families eligibility page lists the Fiancé/Fiancée Scheme, the schemes for married couples and families, the multi-generation scheme and the orphaned siblings scheme. Two people who live together and have no plan to marry do not fit any of them.
That leaves the singles route. A single Singapore Citizen aged 35 and above can buy on their own, and singles can also buy together, up to four of them on one application. It works, and I have had clients do exactly that, but understand what you are signing: co-owners with no family law safety net, whose exit route on a breakup is a sale or a transfer, subject to HDB’s own approval and the minimum occupation period.
The paperwork that does the work
For an unmarried couple, the documents are not paperwork about the relationship. They are the only thing standing where the law would otherwise put a spouse.
- A will each. Without one the Intestate Succession Act 1967 applies, and section 7 distributes the estate to spouse, children, parents and siblings in a fixed order. Your partner is nowhere in it. Our post on dying without a will walks through what actually happens.
- A Lasting Power of Attorney each. Under Part 4 of the Mental Capacity Act 2008, an LPA is what lets your partner make decisions for you if you lose capacity. Without it, a partner has no automatic standing, and someone has to apply to be appointed a deputy.
- CPF nominations. CPF savings do not pass under a will. If you want your partner to receive them, a nomination is the mechanism.
- A written property or cohabitation agreement. Record who paid what for the home, in what shares, and what happens to it if you separate or one of you dies. It is a contract, and courts read contracts.
- Insurance nominations and beneficiary details, checked and updated rather than assumed.
The honest part: none of this is expensive or slow compared with untangling it afterwards. A contested trust claim over a flat costs many times what a will and a properly drafted co-ownership agreement do.
What to do next
Do three things this month. Pull the title search on your home and find out whether you hold it jointly or in common. Write down who contributed what to the purchase, with the transfers to back it up. Then get the will and the LPA done, because those are the two gaps that cause the worst outcomes and the two that are quickest to close.
The first ten minutes with me are free. Book a Discovery Session on wills and estate planning and bring your title details and a rough note of who paid for what. We will tell you where you actually stand and which document closes the biggest hole first, in English, Malay, Mandarin, Tamil, or Vietnamese, with translation staff on hand for each.
