Check the terms of a joint account before you open one.
Opening a joint account takes a few minutes. You go to a branch or open the app together, show your NRICs and sign. Most couples never read the terms that come with it. They usually find out what they agreed to only when something goes wrong: one partner withdraws a large sum without asking, an overdraft appears that neither of you remembers setting up, or one of you falls ill and the bank asks questions the other cannot answer.
There are four things to understand before you open one. Each bank's terms differ, so the aim is to know which questions to ask. You don't need to memorise any one bank's answers.
Every joint account has a signing instruction, sometimes called the mandate. It is the rule you set when you open the account, and it decides who can authorise transactions. There are two common versions.
With "either to sign", either holder can act alone. That includes withdrawing cash, making a transfer, setting up a GIRO and closing a fixed deposit. This suits a household account, because paying conservancy charges or signing a GIRO form should only need one person.
With "both to sign", both holders must agree to every withdrawal or instruction, which gives each of you a veto. It can suit a large savings pot you don't touch often, such as money set aside for a flat. It is slower, and some banks offer fewer online services on accounts that need two signatures.
On an "either to sign" account, the bank usually lets either holder withdraw the full balance. It does not check whether the other holder agrees, and it does not ask whose salary paid in what. This is by design, since a joint account rests on trust. For most couples it causes no trouble, but it matters if the relationship is under strain. It is one reason module 8 tells separating couples to list every joint account early. It is also why many couples using a hybrid model keep only shared costs and shared goals in the joint account and hold the rest of their savings elsewhere.
Ask the bank which arrangements it offers, whether you can change the instruction later, and whether the app and debit cards work under each arrangement.
There are two specific questions to ask here: what happens on the death of a holder, and what happens if the relationship ends.
On death, many joint accounts pass to the surviving holder, so the money does not go through the deceased partner's will. Lesson 7.1, "What happens to your money without a will", explains why that matters. The account terms decide what happens, so check them instead of assuming. The bank may also restrict the account while it processes the death. Ask how long that usually takes and what the surviving holder would need to show.
On separation, the bank will not divide the money for you. If you both agree, you can close or change the account. If you do not agree, either of you might still be able to withdraw on an "either to sign" account, which is why the signing instruction matters. Under some banks' terms, if one holder gives an instruction and the bank receives a contradictory instruction from the other holder before acting on it, the bank may choose to act from then on only on the instructions of all the holders. That is the bank's decision, not a right either of you has to change the signing instruction alone, so ask your bank how it handles conflicting instructions.
Some joint accounts carry linked credit: an overdraft, a credit line or a supplementary card. Under many banks' terms, every holder can be held liable for the whole amount owed, not just their half. If your partner draws an overdraft on the joint account, the bank may pursue you for it.
Joint loans work the same way, for example a joint loan for a renovation or a car. Each borrower is generally responsible for the full repayment if the other stops paying, and missed payments can show up on both borrowers' credit records. You can request your own credit report from Credit Bureau Singapore, and "Credit and debt: scores, cards, loans and BNPL" explains how the report works.
Ask whether the account has any linked credit, how liability works on it, and how to remove a facility you do not want.
Joint accounts are covered by SDIC deposit insurance, but cover on joint accounts is counted under different rules from single-name accounts. Check the current limit and the joint-account treatment on sdic.org.sg rather than assuming. Lesson 1.3 of How money works, "What SDIC deposit insurance covers and what it does not", explains the scheme.
Hui Min and Daniel, the couple from module 1, have not yet chosen a money model. They know a joint account is likely to be part of whichever model they pick, so before opening one they want answers to their questions in writing.
Your questions can come from any of these areas:
signing arrangements and whether they can be changed later whether either holder can withdraw the full balance what happens on the death of a holder what happens if the relationship ends linked credit and who is liable for it how deposit insurance applies to a joint account
Take the same approach. Pick one bank you are likely to use, and work out which four questions you most need answered before both your names go on an account. Then find the answers in its terms or from someone at the branch, ideally in writing.
Write four questions for your bank about a joint account, then find the answers in its terms or ask a staff member.
