Singapore does not recognise common-law marriage. There is no period of living together, not five years, not twenty, that converts a relationship into a marriage or gives a cohabiting partner the rights of a spouse. In the eyes of the law you remain two separate individuals who share an address, and almost every protection that family law offers is switched off.

That single fact drives everything below. There is no pool of “matrimonial assets” to divide when you separate. There is no maintenance for a partner. There is no automatic inheritance. There is no automatic right to make medical decisions for each other. What you have instead is ordinary property law, ordinary contract law, and whatever documents you have taken the trouble to put in place. This guide sets out where you stand in each area and what you can actually do about it.

Why there is no such thing as a common-law spouse here

The Women’s Charter 1961 is the statute that creates spousal rights in Singapore, and almost all of it is triggered by a valid marriage. Division of matrimonial assets under section 112, maintenance for a wife or incapacitated husband under section 113, the ancillary powers of the Family Justice Courts on divorce: all of these begin with a marriage that the law recognises. No marriage, no jurisdiction.

People are often surprised by this because British and Australian television, and reforms in some other jurisdictions, have popularised the idea of a “de facto partner” with something close to spousal standing. Singapore has not gone down that road. There is no de facto regime, no cohabitants’ property statute, and no judicial discretion to redistribute assets between people who were never married.

The practical consequence is that when an unmarried relationship ends badly, the dispute is not a family law dispute. It is a civil claim about who owns what, heard in the civil courts under general property and trust principles, with the ordinary burden of proof and the ordinary costs risk. That is a much harsher environment than an ancillary matters hearing, and it is why documentation matters so much.

Property: the name on the title dominates

For a married couple, whose name is on the title is one factor among many. For an unmarried couple, it is close to the whole story. If the flat or condominium is in your partner’s sole name, the starting position is that it is your partner’s property, and you are the person who has to prove otherwise.

Where both of you are on the title, the next question is how you hold it. A joint tenancy carries a right of survivorship, so the survivor takes the whole property automatically on death. A tenancy in common gives each of you a defined share that passes under your will or under intestacy. The difference between joint tenancy and tenancy in common is the most consequential decision most couples make without thinking about it, and for unmarried couples with unequal contributions, a tenancy in common with expressly stated shares is usually the safer structure.

Where you contributed money but are not on the title, you are left arguing a resulting or constructive trust, namely that the legal owner holds part of the beneficial interest for you. These claims are real and they succeed, but they turn on evidence of what was paid and what was agreed, often years earlier. Contributions to renovation, groceries and bills generally do not create an interest in the property at all. The detail is set out in the guide to property owned with an unmarried partner.

HDB and the housing problem

Housing is where the absence of a legal relationship bites hardest and earliest. HDB’s schemes are built around a family nucleus, whether a couple who are married or applying to marry, or a parent and child, or, for those buying alone, the Single Singapore Citizen Scheme, which opens up from the age of 35. An unmarried couple cannot ordinarily apply for a BTO flat together as a couple. Eligibility rules are detailed and change over time, so check your own position on hdb.gov.sg rather than relying on what a friend was told.

In practice this pushes many unmarried couples into the private rental or resale market, or into a purchase in one name only, which then creates exactly the ownership problem described above.

Money, debts and day-to-day finances

There is no financial obligation between unmarried partners. Neither of you is required to support the other during the relationship or after it. If you gave up work to run the household or to care for a child, that sacrifice generates no claim, unlike in a divorce, where indirect contributions are weighed in the division of assets.

You are also not liable for each other’s debts unless you have made yourself liable, by taking a joint loan, acting as guarantor, or holding a supplementary credit card. That cuts both ways: it protects you from a partner’s borrowing, and it means a partner’s income is invisible when you apply for credit on your own.

Joint bank accounts deserve particular care. Either holder can usually withdraw the full balance, and on death the account may pass to the survivor or may form part of the estate depending on how it was set up and what the bank’s terms say. If you pool money, keep a record of who contributed what and write down what you intend to happen to it.

Children: rights exist, but they run to the child

This is the area where unmarried partners have the most protection, because the law’s concern is the child rather than the couple. Both parents owe a duty to maintain their child regardless of whether they ever married, and either parent can apply to the court about custody, care and control and access under the Guardianship of Infants Act. The framework for guardianship and custody of children is not limited to married parents.

The complication is proof of parentage. A man is presumed to be the father of a child born to his wife during the marriage. Where the parents are unmarried there is no such presumption, so paternity has to be established, usually by the father acknowledging the child at birth registration, and otherwise by a court application supported by DNA evidence. Until that is settled, a maintenance claim can stall. See establishing paternity and the position of children born outside marriage.

Once parentage is established, maintenance is assessed on the same principles as for a child of a marriage: the child’s reasonable needs, measured against each parent’s means. The route for maintenance for a child born outside marriage runs through the Family Justice Courts in the ordinary way.

Illness, incapacity and medical decisions

If your partner is unconscious or loses mental capacity, you have no automatic standing. Hospitals work from next of kin, and a partner you are not married to is not next of kin. Decisions may be taken by parents or siblings you barely know, and in a serious case you may not even be given information.

The fix is a Lasting Power of Attorney. An LPA lets each of you appoint the other as donee for personal welfare, property and affairs, or both, while you still have capacity. It must be made and registered with the Office of the Public Guardian before capacity is lost. After that, the only route is a deputyship application, which is slower, more expensive, and gives the court the final say on who is appointed.

For treatment decisions specifically, an Advance Medical Directive covers a narrow situation, and it is worth understanding what it does and does not cover alongside an LPA.

Death and inheritance

If your partner dies without a will, you inherit nothing. The Intestate Succession Act sets out a fixed order (spouse, children, parents, siblings and so on), and an unmarried partner appears nowhere on that list. The estate goes to relatives who may have played no part in your life together, and the person applying for letters of administration will be one of them, not you.

Three documents change that outcome:

  • A will. The single most important step an unmarried couple can take. Writing a will lets you leave your estate to whoever you choose, including a partner, and lets you name your executor rather than leaving it to statute.
  • A CPF nomination. CPF savings do not pass under a will. They go to your nominees, or under the intestacy rules if you have not nominated. You can nominate a partner. Do it through CPF Board directly.
  • Insurance nominations. Life policies can be written on trust or nominated to a chosen beneficiary. Check with the insurer what form of nomination applies to your policy.

If the property is held as joint tenants, the survivor takes it automatically on death, outside the will. That is sometimes exactly what a couple wants and sometimes a trap. It also means a partner cannot leave their share to a child from a previous relationship.

Immigration and official status

Singapore’s immigration framework recognises spouses, not partners. A Long-Term Visit Pass on the basis of a relationship, dependant status attached to an employment pass, and the sponsorship routes for permanent residence all run through marriage. An unmarried foreign partner generally has to hold a pass in their own right, on their own merits.

The same pattern shows up elsewhere: employer benefits, hospital next-of-kin forms, insurance definitions of family, and public housing eligibility. Where a form asks for a spouse, an unmarried partner usually has no box to tick. Check the rules that apply to your own situation with the Immigration and Checkpoints Authority rather than assuming a long relationship will be treated as equivalent.

The protective steps worth taking

None of the above can be fixed by wishing. It can largely be fixed by paperwork, and the paperwork is not expensive relative to what it protects.

  • Document the property properly. Decide between joint tenancy and tenancy in common deliberately, and if shares are unequal, state them.
  • Make a will each, and update it if you have children or buy property.
  • Make an LPA each, so healthcare and finances do not stall if one of you loses capacity.
  • Complete CPF and insurance nominations. These override the will for those assets, so they need to be consistent with it.
  • Consider a cohabitation agreement recording who owns what, how the mortgage and expenses are shared, and what happens if you separate.
  • Keep records of contributions: transfers, CPF statements, loan repayments. If a dispute ever arises, contemporaneous records are worth more than recollection.

When the relationship ends

There is no divorce to file, no court process to start, and no ancillary matters hearing. You simply stop living together. What remains is a set of civil questions: who owns the property, what happens to the joint account, who takes on the tenancy, who keeps the car.

If you agree, you can document the agreement and implement it: transfer the property, refinance the loan, close the joint accounts, redo your wills and nominations. If you do not agree, a property dispute goes to the civil courts as an ownership claim, which is slower and costlier than most people expect and depends heavily on the evidence you kept at the time.

Children are the exception. Arrangements for a child are dealt with in the Family Justice Courts whether or not the parents were married, and maintenance for the child is enforceable in the ordinary way.
