Joint Tenancy vs Tenancy in Common Explained

Joint tenancy and tenancy in common are Singapore's two ways to co own property. Joint tenancy passes a deceased owner's share automatically to the surviving owners. Tenancy in common lets each owner leave their own share by will. The choice affects inheritance, financing, and how flexibly you can later restructure ownership.

Money: the shares and the tax do not change with the label

Buyer Stamp Duty and, where it applies, Additional Buyer Stamp Duty are calculated on the purchase price or market value of the property, and they apply the same way whether the co owners hold as joint tenants or as tenants in common. The ownership structure itself is not a stamp duty saving tool.

Where the structures do differ is in how rental income and any future sale proceeds are split. Joint tenants are treated as having equal, undivided shares. Tenants in common each hold a distinct share, commonly but not always split evenly, and income or proceeds follow that stated percentage.

Timing: what happens when an owner dies or you want out

Under joint tenancy, if one owner dies, their interest passes automatically to the surviving owner or owners by right of survivorship. It does not form part of the deceased's estate and does not go through their will, so no probate is needed for that property.

Under tenancy in common, each owner's share is part of their own estate. If they leave a will, that share passes according to the will and the executor applies for a grant of probate through the Family Justice Courts. If there is no will, it passes under the Intestate Succession Act through a grant of letters of administration, to whoever the law names as next of kin, which may not be who the deceased would have chosen.

Most married couples default to joint tenancy for its simplicity. Couples or family members with children from a previous relationship, a business partnership, or a wish to leave a specific share to someone other than the co owner often choose tenancy in common instead, precisely because it lets a will control the outcome.

Safety: switching structures the right way

You can convert joint tenancy to tenancy in common. This is called severing the joint tenancy, and it is registered with the Singapore Land Authority, which maintains the official land register for all titled property here. One owner can sever unilaterally using the SLA's prescribed declaration form, or all owners can do it jointly by agreement. The change only takes effect once it is lodged and registered with SLA.

• Use the SLA's own instrument of declaration forms rather than a generic template, since the land register is the definitive record of ownership.
• Confirm with your lawyer whether severing the tenancy alone, without changing the actual shares, avoids a fresh stamp duty charge in your situation.
• If a bank loan is secured on the property, tell your bank before you change the ownership structure, since it may want to review the security arrangement.
• Revisit your will after any change, since a will written for a joint tenancy arrangement may say nothing useful once the property is held as tenancy in common.

Rental income and unmarried co owners

When a co owned property is rented out, rental income is generally reported for tax purposes in line with each owner's actual share, whether that share is the equal split of a joint tenancy or the stated percentage of a tenancy in common. Keep a clear record of who holds what share, since this is what your tax filing should follow.

Unmarried couples, siblings, or friends buying together should think about tenancy in common more carefully than married couples typically do. Without a marriage, the automatic inheritance of a joint tenancy may not match what either owner actually wants, and there is no equivalent to the ABSD remission that IRAS offers to married couples restructuring their holdings. A lawyer can help set out each owner's intended share and what happens if one owner wants to exit, before you commit to a purchase together.

If a joint owner dies while a mortgage is outstanding

Right of survivorship under a joint tenancy passes the property, but not automatically the mortgage terms as they were. The bank will usually require proof of death and will reassess the surviving owner's ability to service the loan alone, since the household income used to originally qualify has changed. Under a tenancy in common, the deceased owner's share and any associated liability instead becomes part of the process handled through their estate, which can take longer to resolve while a grant of probate or letters of administration is obtained.
