Understanding joint bank accounts and wills helps you check whether your inheritance plans match your banking arrangements. You might want your partner to have access to everyday funds while also intending to leave money to your children. Those wishes need to be considered together.

This article expands on PA Law’s short video with practical questions to raise before making a will, adding another account holder or administering an estate.

Joint bank accounts and wills: who receives the money?

The starting point is a presumption of survivorship: when one joint holder dies, the surviving holder or holders are ordinarily entitled to the balance. The Legal Services Commission of South Australia explains that evidence of a contrary intention can rebut this presumption.

This distinction matters when you discuss “my half” of a joint account. Your will cannot simply distribute money that legally passes outside your estate. Equally, an account label should not be treated as a final answer where the underlying ownership is disputed.

Bank administration and an ownership dispute are different questions. For example, ANZ’s bereavement guide explains its usual treatment of joint savings and transaction accounts, including transferring the account into the survivor’s name after receiving the required documents. Check your own bank’s terms and process.

7 essential checks for joint bank accounts and wills

1. Identify every account and each person’s role

Make a list of your everyday accounts, savings accounts, term deposits and any accounts linked to a loan. Record the account holders and bank. Check whether a person is a joint holder, an authorised signatory or acting under a power of attorney. Ask the bank to confirm if you are unsure; these roles should not be treated as interchangeable.

2. Explain why the account is joint

Was the account opened to pool household income? Did you add a child to help pay bills? Were you intending to benefit the survivor? Tell your solicitor the history in your own words. Bring any written instructions or messages made when the arrangement began.

3. Gather records of contributions and intentions

Useful records include opening forms, account terms, statements and evidence of substantial transfers. Identify money from a property sale, inheritance or other significant source. Contributions can help explain the arrangement, but do not assume that paying in all the money, by itself, settles every ownership question.

4. Compare the likely outcome with your intended beneficiaries

Write down who you want to receive the money and why. Then ask whether the account arrangement and your will work together. For blended families, it can be particularly useful to discuss your partner’s immediate needs alongside your children’s intended inheritance.

Illustrative example: A parent wants savings divided equally between two children but adds only one child to an account to help manage bills. The family later disagrees about whether that child was meant to receive the balance. A conversation and document review while the parent can explain their wishes may help identify the risk before a dispute develops. This example does not determine the outcome of any actual account.

5. Check the rest of your estate plan

Joint bank accounts and wills are only part of the picture. The Legal Services Commission’s guide to why you need a will also explains that superannuation does not automatically form part of your estate. Check your fund arrangements separately.

Property ownership needs its own review: real estate held as joint tenants differs from a tenancy in common. The Commission’s explanation of these ownership forms describes the different consequences on death. If you have company or trust interests, bring the relevant documents for advice about those arrangements too.

6. Review changes before changing ownership

A separation, new relationship, death, illness or change in family responsibilities is a useful prompt to review your plan. Seek advice before adding or removing a holder or transferring a significant balance. Explain the result you want, then ask which arrangements could achieve it and what other consequences need checking.

7. Keep a clear record for your appointment and executor

Bring your current will, account list and relevant documents to your appointment. Make a note of unresolved questions and where the original records are kept. Keep account information secure, and ask how to provide it to your solicitor safely. You do not need to email passwords or online banking login details.

What should you do after an account holder dies?

Contact the bank’s bereavement team. Confirm which accounts were held jointly, what documents are required and how direct debits or linked loans will be managed. A joint savings account and a joint loan are different products; do not assume that the treatment of one answers questions about the other.

For example, ANZ’s published guide says the survivor can continue using their own debit card for a joint account, while the deceased person’s card is cancelled. Check the position with the relevant bank rather than using the deceased person’s card or login.

If you are an executor and there is uncertainty about ownership, identify the account and obtain advice before deciding how to treat it. If family members disagree, preserve statements and relevant correspondence and seek prompt advice before distributing disputed funds. PA Law can discuss the next steps through its estate administration services.

Frequently asked questions about joint bank accounts and wills

Does a joint bank account form part of a deceased estate?

Usually, the balance passes to the surviving account holder. However, evidence about the intended ownership can change the position. A joint account should be identified when reviewing an estate, even if the balance is ultimately dealt with outside it.

Can I leave my half of a joint account to my children in my will?

Do not assume that a will clause can achieve this. If survivorship applies, the money passes to the surviving holder. Ask your solicitor to review the account arrangement alongside your intended gifts before you sign or change your will.

Does adding an adult child mean they inherit all the money?

There is no safe universal answer. The reason for adding the child, account documents, contributions and evidence of intention may matter. Explain whether the arrangement was intended as a gift, assistance with bills, or something else.

Will the bank freeze a joint account when someone dies?

Bank procedures depend on the product and circumstances. A surviving holder may be able to continue using their own access while records are updated. Contact the bank’s bereavement team and ask about any restrictions, required documents and linked payments.

Is probate always needed for a joint bank account?

An ordinary joint account passing by survivorship can often be dealt with without a grant for that account. Ask the bank what it requires. Probate may still be needed for other assets, and an ownership dispute requires separate advice.

Do I still need a will if most of my assets are jointly owned?

A will remains relevant to estate assets, the appointment of an executor and what happens if the other holder dies first. Joint ownership is only one part of an estate plan; your arrangements should also address changes in circumstances.
