The Long Arithmetic: Issue 19

On one of our trips, my husband had done the vacation planning.

Most of the details we needed were on his phone.

Then his phone hit 1%.

He shared the itinerary with me before the phone died, so we kept going.

But in that moment, we realized how much of the trip had depended on one person having the information.

Neither of us had planned it that way. It had happened naturally because he was the one who organized the trip.

I think a lot of family financial lives work the same way.

One person may know where all the information is and assume their spouse or partner could find it too.

The investment accounts. The insurance. The tax returns. The LLCs. The estate documents. The private investments that send notices at irregular times. The accountant who handles one thing and the attorney who handles another.

Maybe the other spouse knows pieces of it. Maybe quite a few pieces.

But if you asked, “Could you run this without me?” the answer might be very different.

There’s nothing obviously wrong with dividing responsibilities inside a household.

One person handles travel. The other deals with the contractors. One knows the doctors. The other knows the passwords, the investments, and why there are three accounts that appear to do the same thing.

That division can be efficient.

Researchers Adrian Ward and John Lynch studied something very close to this. A University of Texas write-up of their work calls the partner with primary financial responsibility the household “CFO.” Their research found that couples do not necessarily start with the more financially knowledgeable partner taking the job. Over time, though, the person doing the financial work learns by doing while the partner who handed off responsibility does not develop at the same pace. The longer the relationship, the wider that knowledge gap can become.

That finding makes intuitive sense to me.

If you have spent twenty years opening the bank and utility statements, talking to the CPA, choosing the insurance, reading the investment documents, and answering the questions, you have accumulated something that does not appear on a balance sheet.

You know how the system works.

The other person may know perfectly well that the system exists. That’s not the same thing.

This is where I think the usual idea of being “organized” falls short.

You can have a will.

You can have a trust.

You can have neatly labeled folders and a password manager and an excellent financial advisor.

And you can still have a financial life that depends heavily on one family member’s memory.

The legal documents may say who has authority. They do not necessarily explain why an account is there, which professional handles which problem, what is supposed to happen next, or which email you should not ignore.

An investment statement can tell someone what you own.

It cannot tell them that this particular investment requires a capital call notice to be watched, while that one is simply supposed to sit there.

A list of professionals can tell them who your CPA is.

It may not tell them that the CPA handles the tax return but does not understand the private investments particularly well, or that the estate attorney should be called before anyone changes the ownership of an account.

Those little pieces of context are where the system lives.

And a surprising amount of them may live only in your head.

Most talk about passing on wealth is about children. In many families, though, a spouse may be the first person who has to take over.

This is where I would resist the obvious solution.

If you are the one who runs the money, the answer is probably not to turn your spouse into another version of you.

Maybe they have no interest in reading investment reports. Maybe they would rather do almost anything than sit through a meeting about entity structure. Maybe your division of labor has worked beautifully for decades.

There is no obvious virtue in making two people equally expert at everything.

I have seen this with a couple I worked with.

The husband handled the finances. His wife was clear that she did not want to become the financial expert in the house.

She wanted something much more practical: to understand what they had, where to find it, what she would need access to, and what to do if she ever had to step in.

She also told me that talking about the money at home was hard. The system made sense to the person who managed it, but the way it was explained was not always clear to her.

Working through it with her helped her get clearer on what she needed to access and how to navigate the information.

She did not need his job. She needed enough of the map to know where to start.

So the question is not how to make them an expert.

How much would the other person need to know to function if you could not answer the phone?

I don’t think that means knowing how to evaluate every investment.

It probably means knowing what exists.

Where the important information lives and how to access it.

Who to call.

What needs attention soon, and what can wait.

And perhaps most important, where their own knowledge ends so they know when to stop and call someone.

That’s very different from financial literacy in the traditional sense.

It’s more like orientation.

If you walk into a building you have never worked in, you don’t need to understand the electrical system to find the exits. But somebody should probably show you where these exits are in case the lights go out.

Imagine that tomorrow morning you are unavailable.

Nothing dramatic needs to have happened. You could be traveling somewhere hard to reach or dealing with a family emergency. The reason matters less than the fact that it is difficult to reach you or ask you.

There is some reassuring research here. Economist Joanne Hsu studied older married couples in which husbands tended to manage the finances. She found that women increased their financial literacy as expected widowhood approached. About 80 percent in her sample would catch up with their husbands before the expected onset of widowhood. That suggests some people learn when the need becomes visible. But her study looks at a gradual transition. A sudden absence does not come with years to prepare.

Are you the one managing your family’s financial information? Now imagine your spouse or another person you trust sitting down at your desk.

Where do they start?

Do they know which accounts exist?

Can they tell which entities own which assets?

Would they recognize a notice that needs action?

Do they know which professional to call for which question?

Could they find the insurance policies?

Would they know where the estate documents are?

Would they know what not to touch?

That last one may matter as much as everything else.

A good handoff is not only about giving someone access. It is also about helping them understand the boundaries.

Some things need action.

Some things need a professional.

Some things need to be left alone.

Without context, they can all look equally urgent.

There’s a strange thing about competence.

The better you get at running something, the easier it becomes to stop explaining how you run it.

You know the accountant. You know the investment. You remember why the insurance changed. You know which document is current and which one is sitting in the folder only because nobody deleted it.

So the household can look increasingly sophisticated while becoming more dependent on you.

That is not necessarily poor planning.

It may simply be what happens when one person has been doing a job for a long time.

But eventually, I think there is another question to ask.

Not only: Have I organized everything?

Also: Could someone else use what I organized?

Those aren’t the same standard.

The goal probably isn’t to eliminate the knowledge gap between two people. That may be unrealistic and unnecessary.

A better goal may be to make sure the gap is survivable.

The person taking over doesn’t have to know everything you know.

They need enough of the map that they are not starting from a blank page.

So maybe the test is simple.

If the person who knows where everything is could not answer the phone tomorrow, would the other person know what to do?

If this made you think of someone, feel free to forward this issue to them.

P.S. I’ve been thinking about what it would take to help a spouse or family member step in, without asking them to become the household’s financial expert.

I’m continuing to research this problem, and I’m exploring a more structured way to help families organize the financial life one person usually carries, then help the next person understand enough of the system to step in without starting from zero.

My working name for it is “Family CFO-ready,” and I’m not sure it’s the right one. If this is a problem in your household, reply and tell me what feels hardest. I’d genuinely like to understand. Names always stay private.
