Multiple Bank Accounts and Estate Planning Chaos

The average Australian has 2.4 bank accounts. That figure might sound modest, but it masks a more complicated reality. Between everyday transaction accounts, high-interest savings, offset accounts, business accounts, and accounts opened for specific purposes then forgotten, many people have far more banking relationships than they actively track.

The rise of neobanking has only accelerated this fragmentation. Digital banks make it trivially easy to open new accounts. Better rates here, a specific feature there, a promotional offer somewhere else. Each new account feels like optimisation. But what looks like smart money management during life can create a genuine administrative nightmare after death.

This isn’t about having multiple accounts per se, but it is more about what happens when those accounts aren’t visible, documented, or structured in a way that makes sense to anyone other than you.

The neobank effect

Australia’s digital banking boom has fundamentally changed how people manage money. The neobanking market has grown rapidly, projected to reach $60.72 billion by 2032. Digital-first banks like Up and ubank have made account creation frictionless. No branch visits, no paperwork, just a few taps on your phone.

The convenience is real. People can separate their spending from savings more effectively, take advantage of better rates, and manage their money with more granularity.

The structure looks like this:

Transaction account for daily expenses
High-interest saver for emergency funds
Offset account linked to mortgage
Separate account for bills
Another for holiday savings
Business account or two

Each one makes sense in isolation. Together, they create administrative chaos for whoever has to deal with your estate.

Why digital banks are different

Unlike traditional banks where you might have had a relationship manager or at least visited a branch occasionally, digital banks exist entirely online. There’s no paper trail sitting in a filing cabinet, no branch that knows your face, no annual statement arriving by post unless you’ve specifically requested it.

Every account is another institution to notify after death. Another set of access credentials to discover. Another balance to track down. Another probate threshold to consider.

The $2.6 billion sitting in limbo

Around $2.6 billion in unclaimed money is currently held by ASIC from lost shares, bank accounts, and life insurance policies. A substantial portion comes from dormant bank accounts.

Here’s how it happens:

You open a high-interest savings account for a specific goal. Maybe you’re saving for a renovation, or building a buffer for potential income disruptions. The goal gets met or circumstances change. The account still exists, slowly accumulating interest, but you’ve moved on to other priorities.

No transactions. No attention. Seven years pass faster than you’d think.

After seven years of inactivity, accounts with balances over $500 are transferred to ASIC’s unclaimed money register. The money isn’t lost forever (you or your heirs can claim it), but it adds another layer of complexity to estate administration.

The multiplication effect

Now multiply that scenario across a population increasingly comfortable opening accounts online:

The promotional high-interest account from 2018
The business account from a side project that didn’t take off
The joint account with an ex-partner that was meant to be closed but somehow never was
The savings account your parents opened for you as a teenager that still has $200 in it

Each forgotten account doesn’t just represent unclaimed money. It represents information that won’t be in your will, won’t be known to your executor, and won’t surface easily during estate administration.

What executors actually face

When someone dies, their executor needs to identify, secure, and eventually distribute all assets. Bank accounts are usually straightforward in theory.

In practice, finding them can be remarkably difficult.

The discovery problem

If you’ve documented everything meticulously (most people haven’t), your executor might have a list. More commonly, they’re working from:

Bank statements they can find
Emails mentioning accounts
Educated guesses about where you might have kept money

They’ll contact the obvious institutions. The Big Four banks. Maybe a credit union if you’ve mentioned it.

But what about the neobank account you opened to get a signup bonus? The international transfer service that also functions as a bank account? The fintech app that holds a balance?

These don’t show up in traditional searches. They don’t send mail to your address unless you’ve explicitly enabled that. They exist in apps on a phone that might be locked, or in emails buried in an inbox.

The administrative multiplication

Each discovered account triggers its own administrative process. Banks typically require either a Grant of Probate or Letters of Administration before releasing funds, though each bank has its own threshold (generally ranging from $1,000 to $100,000) below which they might release funds with just an indemnity form.

The problem compounds when accounts are scattered across different banks. Your executor might get probate sorted for your main accounts at Commonwealth Bank, only to discover three months later that you had $15,000 sitting in an account at a digital bank nobody knew about.

That account still needs documentation. Still needs to go through its own release process. Still delays final distribution to beneficiaries.

Joint accounts: when convenience becomes confusion

Joint accounts add another dimension of complexity. When one holder of a joint account dies, the surviving account holder typically becomes sole owner of the entire balance through the right of survivorship. The funds don’t form part of the deceased’s estate.

This works perfectly when it’s intentional. A married couple with a joint transaction account for household expenses. The surviving spouse gets immediate access to funds without waiting for probate.

It creates problems when it’s structural.

Consider these scenarios:

An elderly parent adds an adult child to their account to help with bill payments
Someone adds a partner to an existing account when they move in together
A business partner gets added for operational reasons

In these cases, the legal outcome (entire balance goes to surviving account holder) might not reflect the actual intention (the balance was meant to be distributed according to the will).

Estate disputes can follow, especially if other beneficiaries believe the joint account holder received assets they weren’t entitled to.

The more bank accounts someone has, the more opportunities for this kind of structural mismatch. An account might have been joint for one reason but is now joint for historical inertia.

The probate threshold game

Different banks have different thresholds for requiring probate:

Some will release up to $15,000 without formal documentation
Others want probate for anything over $5,000
The variation isn’t standardised

This creates perverse outcomes.

Someone might have $80,000 spread across six accounts at different institutions, each holding less than $15,000. The intent might be diversification or rate-chasing. The effect is creating six separate administrative processes rather than one.

The timing impact

Getting probate in New South Wales typically takes several months. Once granted, banks generally release funds within two to three weeks.

But that assumes the executor knows about all the accounts upfront. Each newly discovered account extends the timeline. Each account at a different institution potentially requires separate coordination.

From an executor’s perspective, consolidation would be simpler. But many people don’t realise this matters until it’s too late. They’re optimising for features, rates, or convenience during life, not for administrative efficiency after death.

The digital access problem

Most people now manage their banking entirely online:

Statements are digital
Communication is via email or app notifications
Passwords and two-factor authentication protect everything

When someone dies, their executor needs information about these accounts to manage the estate.

But how do you log into a banking app when you don’t know the password? How do you even know which apps to look for?

The standard process

The typical approach involves contacting each bank, proving you’re the legitimate executor (usually with a death certificate and Grant of Probate), and requesting statements and balance information.

But you can only do this if you know the bank exists in the first place.

Digital-only banks exacerbate this because they leave fewer physical traces. No branches. No paper statements arriving by post. No annual summaries. Just an app on a phone and a digital relationship that might be completely invisible to everyone except the account holder.

The real costs

This complexity has tangible impacts:

Financial:

Legal fees for obtaining probate
Direct debits that continue running on accounts nobody knew existed
Fees that accumulate
Interest that stops being earned when accounts are frozen
Accounts that go dormant and eventually get transferred to ASIC

Time:

Hours spent by executors tracking down accounts
Delays in distributing assets to beneficiaries who might need them

Emotional:

Grieving family members navigating bureaucracy
Discovering that their loved one’s financial life was more fragmented than anyone realised
Frustration of finding small amounts scattered across multiple institutions, each requiring its own paperwork

What actually helps

The solution isn’t necessarily to consolidate everything into a single account. Multiple accounts can serve legitimate purposes. But they need to be documented, structured appropriately, and actually serve a function.

Create an asset register

A comprehensive list of all accounts transforms estate administration from an archaeological dig into a straightforward process.

This doesn’t need to be complex:

List each institution
Note account type
Approximate balance
Purpose
Access details

Store it securely. Update it annually. It becomes invaluable.

Review your account structures

Look at your accounts through an estate lens:

That joint account you set up for convenience in 2015 – does it still serve that purpose?
Is the joint holder who you’d actually want to inherit those funds?
The business account for the side project that ended – should it just be closed?

Understand what passes where

Know which accounts will be probate assets versus which pass automatically through joint ownership. Make sure your will actually addresses how you want bank assets distributed rather than assuming it’ll all be obvious.

The wider pattern

Financial fragmentation isn’t limited to bank accounts. It applies to investment platforms, cryptocurrency exchanges, peer-to-peer lending, international money transfer services that hold balances, and any other digital financial service.

Each one is another account. Another password. Another institution that needs to be notified. Another potential complication.

But bank accounts are foundational. They’re where most people start, where most money sits day to day, and where most complications actually emerge in practice. Getting this right (or at least less wrong) makes everything else easier.

The core tension is obvious and permeates much further than you might think. Modern financial services genuinely are more sophisticated when you can segment and optimise across multiple accounts. The friction of maintaining fewer accounts might cost you hundreds or thousands of dollars annually in worse rates or less optimal arrangements.

But the transaction costs that hit your estate – measured in legal fees and executor time and delayed distributions – can quickly exceed any benefit you captured during life.

There’s no perfect answer. Just the awareness that every account you open is creating future work for someone else, and that work deserves at least a moment’s consideration before you click “open account” on the next high-interest offer.
