One Spouse Manages All the Money: What Happens When They Can’t?

Wealth and readiness are different things

Imagine a couple with a substantial home, retirement funds, several investment accounts, a small offshore portfolio and perhaps an interest in a family business. Their affairs might be well managed. Their adviser may be capable, the investments sensibly structured and the estate plan recently reviewed.

Yet if one spouse were unexpectedly admitted to hospital tomorrow, could the other answer six basic questions?

• What do we own, and in whose name?
• Where does our monthly income actually come from?
• Which payments need to continue, and from which account?
• Who are our advisers, trustees and relevant service providers?
• Where are the important legal and financial documents?
• Who has the legal authority to act, rather than merely knowing a password?

There is a meaningful difference between a household that is wealthy and one that is ready to manage an interruption. The first describes the balance sheet. The second describes the ability to make decisions and keep things working when circumstances change.

That distinction becomes more important as the financial picture grows: multiple platforms, retirement-income products, companies, trusts, different currencies and adult children in different countries. What seems obvious to the person managing it can be impenetrable to everyone else.

Three events, three different problems

It helps to distinguish three situations that are often bundled together under the reassuring heading of ‘estate planning’.

A temporary interruption

Someone is ill, travelling unexpectedly or simply unable to handle their usual financial administration for a few weeks. Bills, debit orders, medical costs and routine communications still need attention. The immediate problem is practical continuity: information, approved access and a second person who knows what to do.

A loss of decision-making capacity

Longer-term incapacity is more complicated. In South Africa, a conventional power of attorney does not automatically continue operating after the person who granted it loses the legal capacity required for that authority. Depending on the circumstances, a court-appointed curator or an administrator under the Mental Health Care Act may be relevant. The process and eligibility are not interchangeable and require legal guidance.

The Master of the High Court’s guidance on curators and administrators is a useful starting point. The important lesson is that knowing what your spouse would want is not the same as having legal authority to transact on their behalf.

Death

On death, estate administration brings another set of rules. The deceased estate must be dealt with through the appropriate legal process; a spouse’s familiarity with the accounts does not replace an executor’s authority. Beneficiary arrangements for particular products and ownership through trusts or companies also need to be understood separately from the will.

Our South African estate-planning guide explains the broader estate questions. The point here is narrower: information, access and legal authority must all be addressed, because one cannot substitute for the others.

Build a financial continuity map

A sensible first step is a concise household financial map. Not a 90-page folder of statements and product brochures. Those may have their place, but they are unlikely to be the document someone reaches for in a difficult week.

Think of a secure, regularly updated guide that shows the financial structure and where to find authoritative details. It might cover the following:

Keep sensitive information secure. The map should explain where authorised records and access arrangements are held, not become a spreadsheet of shared passwords, PINs and unrestricted account credentials. Banks, platforms and professional advisers should confirm appropriate access and mandates for the relevant person.

The goal is not to document every transaction. It is to make the household understandable to someone other than its usual financial manager.

Make sure everyday money can still flow

A common planning blind spot is the gap between having wealth and being able to use it at the right time.

The household may have ample investment capital but only one spouse understands how to pay the medical aid, where monthly living expenses are funded, or whether income depends on a particular instruction. There may be sufficient assets to support the family for decades, but uncertainty about what happens next Tuesday.

It is worth reviewing how each spouse would meet immediate living expenses in the event of illness, incapacity or death, taking account of account ownership, available funds, bank mandates, legal restrictions and expected administrative delays. The answer may be different for each event; no single account structure solves all three.

The question is not whether to hold more cash indiscriminately. It is whether the household has an appropriately funded and legally accessible way to continue meeting its obligations while more complex matters are resolved.

Shared understanding, not shared expertise

It would be unrealistic, and often unnecessary, to insist that both spouses suddenly become equally interested in asset allocation, the subtleties of offshore tax or the latest investment research. If one loves spreadsheets and the other does not, marriage has presumably survived worse differences.

What matters is that both understand the financial architecture well enough to ask informed questions and know where to turn. That means discussing not just what is owned, but what the assets are supposed to achieve.

• Which capital supports our standard of living?
• Which investments are long-term and should not be disturbed without advice?
• What would change financially if one of us died?
• Which decisions would need legal, tax or fiduciary input?
• Who would coordinate the overall picture if our usual decision-maker could not?

Where appropriate, both spouses can attend periodic planning meetings and know the relevant adviser or professional team. This need not turn every household discussion into an investment committee meeting. A shared conversation once or twice a year is often more valuable than a large collection of documents neither person has read.

The two-hour household test

A practical way to judge whether the arrangements are adequate is to set aside two hours and assume the spouse who normally manages everything is unavailable for the next three months.

Could the other person locate the latest financial overview, understand the next month’s cash flow, contact the right professionals and identify which decisions they are legally able to make? Could they explain the broad strategy to an adult child or trusted professional without relying entirely on memory?

If not, make a short list of the gaps. Start with the ones that would create immediate disruption. Then address the legal-authority and document questions with the relevant specialists. Review the map after major family, business or financial changes, not just when a new will is signed.

The test is deliberately modest. It is not asking whether someone could manage a R40 million portfolio alone. It is asking whether they would know where to begin and whether the household could remain functional.

For families whose finances extend across companies, trusts and jurisdictions, professional coordination is especially important. Our financial-planning guide explains why a complete plan involves more than the investments themselves.
