Joint Accounts and the Family Home
The way your name sits on the title deed can matter more than anything written in your will. (Ownership type as a silent instruction.)
For most households the home is the largest asset, so how it is held shapes the whole estate. Property in Singapore can be owned by two or more people in one of two ways, and the difference decides what happens when an owner dies.
Joint tenancy carries a "right of survivorship". When one joint owner dies, their share passes automatically to the surviving owner(s) — outside the will, regardless of what the will says. Many married couples hold their home this way, so that the survivor keeps the home without probate delay. The flip side: you cannot leave your share to anyone else while holding it jointly, because survivorship takes precedence.
Tenancy-in-common gives each owner a distinct share (which need not be equal). There is no survivorship: when an owner dies, their share passes under their will, or by the intestacy rules if there is no will. This suits people who want to leave their share to someone other than the co-owner — a child from an earlier marriage, say.
The same logic applies to joint bank accounts, where the surviving holder generally retains access to the funds, though the legal ownership of the balance can be more nuanced than survivorship alone.
The practical step is to check how your home is actually held — the title document states it — and confirm that the holding type matches your intention. Couples can convert between the two forms while both are alive. Aligning ownership with your wishes is as important as the will itself, because for this asset the ownership type, not the will, often has the final say.
Illustrative example: joint tenancy versus tenancy-in-common
The chart contrasts the two holdings for a co-owned home — under joint tenancy the share passes automatically to the survivor; under tenancy-in-common it passes by the will. Same property, same co-owners, two different destinations decided purely by how the title is held.
