Marriage in Singapore is between a man and a woman. A same-sex marriage is not available here, and a same-sex marriage validly contracted overseas is not recognised in Singapore either. The legal consequence is straightforward: a same-sex couple in Singapore stands in the same position as any other unmarried couple, and nothing about the relationship is presumed by the law.
That makes private arrangements the whole of the picture. Wills, Lasting Powers of Attorney, property documents, nominations and written agreements are the tools that actually determine what happens if one partner dies, loses capacity, or the relationship ends. This article sets out the current legal position and then works through each of those tools in turn.
The current legal position
Two changes in 2022 are often discussed together and are worth separating.
First, section 377A of the Penal Code, which criminalised sexual acts between men, was repealed. Second, and at the same time, the Constitution was amended to protect the definition of marriage from constitutional challenge, so the definition of marriage, and policies built on it, cannot be struck down by a court on constitutional grounds. Parliament retains the power to define marriage.
Neither change altered marriage law, family law entitlements, or housing policy. Marriage under the Women’s Charter remains a union between a man and a woman. Because Singapore does not recognise the marriage, there is also no divorce, no division of matrimonial assets and no spousal maintenance available to a same-sex couple here, even one that married abroad and later separates.
What follows from that is not unique to same-sex couples. It is the same body of law that governs every unmarried couple in Singapore, set out in the guide to the legal rights of unmarried couples. Property is dealt with under ordinary property and trust law. There is no concept of common-law marriage, and living together for many years creates no entitlement by itself.
A will is the first document, not an optional one
If you die without a will, the Intestate Succession Act decides who inherits. It distributes an estate among a spouse, children, parents, siblings and other listed relatives in a fixed order. A partner does not appear anywhere on that list. A partner of thirty years receives nothing, and the estate passes to relatives who may be estranged or unaware of the relationship.
A valid will fixes this. It lets you leave your estate as you choose, name your partner as a beneficiary, and appoint an executor you trust to administer it. The requirements, which include signing in the presence of two witnesses who are not beneficiaries and the rest of the formalities, are covered in the guide to writing a will in Singapore.
Naming your partner as executor is worth considering separately from naming them as a beneficiary. Without a will there is no executor, and someone must apply for letters of administration, a right that follows the same statutory order of priority, which again means a relative rather than a partner. Even a partner who has been left the whole estate under a will is in a far weaker practical position if they are not the executor.
One practical point: marriage revokes an existing will in Singapore unless the will was made in contemplation of that marriage. That is not a live risk for a couple who cannot marry here, but it matters if either partner later enters a marriage recognised in Singapore.
An LPA so your partner can act if you cannot
A Lasting Power of Attorney is a document made under the Mental Capacity Act while you still have mental capacity. It appoints one or more donees to make decisions for you if you later lose capacity, whether through an accident, a stroke, or a progressive illness.
An LPA covers two areas, and you can grant either or both:
- Personal welfare: medical treatment, care arrangements, where you live, and who has access to you.
- Property and affairs: bank accounts, bills, property, and managing your finances.
There is no restriction on appointing a partner as donee. Without an LPA, a partner has no automatic authority at all. Hospitals will look to next of kin; banks will freeze accounts; and someone, very likely a family member, would need to apply to court to be appointed deputy, a slower and more expensive process with an uncertain outcome for the partner. The mechanics of making one are in the guide to the Lasting Power of Attorney in Singapore.
An Advance Medical Directive is a separate and much narrower document dealing only with the withholding of extraordinary life-sustaining treatment in terminal illness. It does not appoint anyone, and it is not a substitute for an LPA.
Property: put the shares in writing
Where two people buy property together, the single most consequential decision is the manner of holding, and it is made at the point of purchase.
Joint tenancy means that on the death of one owner, that owner’s interest passes automatically to the survivor by right of survivorship, outside the will. Tenancy in common means each owner holds a defined share which forms part of their estate and passes under their will, or under the intestacy rules if there is none. The difference is explained fully in the guide to joint tenancy versus tenancy in common.
Where the contributions are unequal, tenancy in common with shares that reflect the actual contributions is usually the cleaner arrangement, and it should be documented at the outset rather than reconstructed years later from bank statements. Where one partner contributes to a property held in the other’s sole name, whether paying the deposit, servicing the mortgage or funding renovations, nothing is presumed. Any claim runs through the law of resulting and constructive trusts and depends on evidence. The general framework is in the guide to property rights for unmarried couples.
Keep records: who paid what, from which account, and on what understanding. A short signed declaration of trust recording the intended shares is cheap now and decisive later.
A cohabitation agreement
A written agreement between partners can record what you both intend about the home, contributions to household expenses, ownership of significant assets, what happens to shared accounts, and how things are unwound if you separate. It cannot create the legal effects of marriage, and it cannot bind a court on anything concerning children. Within its proper scope it is a contract, and the practical value is mostly in the clarity it forces at a calm moment. The guide to cohabitation agreements in Singapore covers what such an agreement can and cannot do.
Nominations: CPF, insurance and the rest
Some of the largest assets a person holds never pass under a will at all, and this is one of the most common planning failures.
CPF savings do not form part of your estate and are not distributed by your will. They pass to whoever is named in a CPF nomination, and if there is no nomination they go to the Public Trustee for distribution under the intestacy rules, which again excludes a partner. There is no restriction on nominating a partner. The available nomination options are set out in the guide to CPF nomination types.
Insurance policies with a named beneficiary pay out directly to that beneficiary. Employer group life cover, retirement accounts and investment platforms usually have their own beneficiary forms. Go through every one of them, and diarise a review whenever your circumstances change.
Housing and children
HDB eligibility schemes are built around defined family nuclei, and a same-sex couple does not form one for those purposes. Separately, some schemes are open to single Singapore citizens who meet an age requirement, and two unrelated individuals may in some circumstances apply under schemes designed for that. Eligibility rules, income ceilings and age thresholds change, so check the current position directly with HDB rather than relying on what was true a few years ago. Private property carries no equivalent eligibility restriction, though financing, stamp duty and the manner of holding all need thought.
On children, Singapore law attaches parental rights and duties to legal parenthood, not to a relationship between adults. A partner who is not a legal parent has no automatic standing in relation to a child: no say in medical or school decisions, and no automatic position if the legal parent dies. Adoption in Singapore is governed by statute and is subject to eligibility requirements and the court’s assessment of the child’s welfare. Guardianship and testamentary guardianship provisions exist but do not operate as a substitute for legal parenthood. These are fact-specific questions where general information is a poor guide, and they are worth taking individual advice on early rather than after a crisis.
Where to start
The order that tends to work is: a will each, an LPA each, then the property documentation, then the nominations, then an agreement if you want one. Each is a discrete piece of work and none of it depends on the others being done first.
Review the whole set after any significant change: buying or selling a home, a serious illness, a move overseas, the arrival of a child, or a separation. None of these documents update themselves. If you want advice on your own situation, we can connect you with a licensed Singapore law practice.
