Family trust protocol: one conversation before the urgent call

Practicum for Book 3, The Economics of Trust, Chapter 13. Version: 2026-08-12. Setup time: 15 to 20 minutes. This protocol does not teach you to detect a fake voice. It gives you steps that work whether the voice is real or fake.

1. Choose a family check phrase

The phrase is not a password that authorizes a payment. It is a stop signal. A correct answer lowers the risk, but you still confirm an expensive request through an independent channel.

A good phrase:

does not appear on social media, in messages, or in family greetings;
is not a pet's name, address, birth date, or mother's maiden name;
is easy to say and remember;
is known only to relatives who follow the agreement.

We keep our phrase in this agreed secure place, not on this page: _______________

People who know it: ___________________________________________________________

Test it aloud once during a normal conversation. Do not send it through the same chat where a fraudulent request could arrive.

2. Agree on the response

If a voice, video, or message from a relative asks for money, access, a document, or a secret code:

Ask for the check phrase.
Whatever the answer, do not pay or share information through the same contact.
End the conversation.
Contact your relative yourself through a saved number or another relative.
Do nothing if you cannot confirm the request.

Urgency does not stop you from helping. It stops you from acting through one channel. Treat anyone who claims to represent a bank or public agency the same way: end the call, then contact the organization through an official number you found yourself.

What these scams usually look like

You do not need a catalog of horrors or a lesson in detecting a fake by ear. That approach does not work. These schemes follow a similar script, and one rule can break all of them.

Scheme	What happens	What makes the attack harder
"A relative is in trouble"	A voice that sounds like a child or grandchild urgently asks for money	Ask for the check phrase, then call the saved number yourself
"Bank security"	The caller leads you toward a transfer to a "safe account" or asks for a text-message code	Hang up and call the number printed on the card
A call presented as a survey	The caller tries to collect a recording of your voice to build a clone	Do not have long conversations with unknown callers
A video message "from a relative"	The face and voice look real, but the request comes from someone else	A video is not confirmation. Apply the same rule

Shared pattern: urgency plus money, data, or access means stop. A real emergency can survive a two-minute check.

Workplace schemes, including a fake message from an executive, changed payment details, and review attacks, appear in the Personal trust perimeter.

3. Talk with parents and older relatives

Do not start with a list of technologies or frightening examples. Say this:

"Scammers can now speak with the voices of people you know. You do not have to tell a real voice from a fake one. If anyone asks for money, hang up and call me yourself using your saved number. The real me will never be offended by the check."

Then add the second half:

"If they fool you, or if you only start to feel unsure, call me right away. I will not scold you or take away your independence. First we will stop the loss. Then we will work out what happened."

Removing shame is part of the protection. A person who fears the family's reaction waits longer before calling the bank or police.

Add the bank controls available where you live

Check whether your bank lets you lower transfer limits, require an extra confirmation for large payments, freeze a card quickly, or disable features you do not use. Names and rules differ by bank and country. Use the bank's official app or site to confirm the current terms, then choose controls your family can explain and use.

Do not assume that a cooling-off period, dispute deadline, or reimbursement rule works the same way everywhere. Check the current process with your bank or local financial regulator before you need it.

4. Children and teenagers

A child needs the same check phrase and a shorter rule:

"If an adult you do not know says your parents are in trouble, asks you to turn on the camera, find money, show valuables, or keep the call secret, end the conversation and call your trusted adult right away."

A child does not help an "investigation" by phone, show the home on video, or search for family money at a caller's direction.

5. Your AI agents and family money

If an assistant can order or pay for things, make an agreement with it too:

Setting	Our decision
Maximum amount for one purchase
Maximum amount per month
What it may buy on its own
What it may only add to a cart
Which subscriptions and extra charges are forbidden
Where we can see notifications and the activity log
How to cancel an action or dispute a payment

If you cannot remember the agent's limit, assume there is no limit.

6. The first hours after fraud

Stop the loss first. Work out how it happened afterward.

Contact the bank through an official number printed on the back of the card, shown in the banking app, or listed on the bank's official site. If you may have exposed card details or remote access, ask the bank to block the card and remote access.
Preserve the trail: time, phone numbers, addresses, messages, receipts, screenshots, and the amount. Do not delete or "improve" anything.
Ask the bank to open a dispute or recall request if money moved without your consent or because of fraud. Follow the deadline and evidence rules in your country. Record the case number and every answer.
Use your local fraud-reporting route. This may be the police, a national fraud service, or a financial regulator. Keep the report number and any written confirmation.
Tell someone close to you. Do not face the shame and follow-up calls alone. So-called helpers may promise to recover the money and try to scam you again.

A bank does not always have to return the money, especially when the customer confirmed the transfer. Do not promise yourself or your relative a guaranteed refund. Act quickly and record every contact.

Card to keep by the phone

ARE THEY ASKING FOR MONEY OR DATA?

I do not argue or transfer anything.

I hang up.

I call my relative or bank myself using a saved official number.

I never share text-message codes, card details, or passwords.

If I already shared or transferred something, I call the bank and my relative at once.

A real relative will not be offended by a check.

Print this block in large type and leave it near the phone. Rehearse the sequence once: who calls whom, which number they use, and what happens if the first person does not answer.

A separate large-print card for older relatives

Print this version in the largest practical type and leave it by your parents' home phone. It is shorter because nobody reads a long list during a stressful call.

OUR PHRASE: ______________

If someone calls and asks for money, even in the voice of my child or grandchild:

I ask for our phrase.

I hang up. This is not rude.

I call back myself using my saved number.

I never share a text-message code. With anyone. Ever.

A bank or the police will never ask me to transfer money to a "safe account."

If I already transferred money or shared a code, I call right away:

My relative: ______________ | Bank: number on the back of my card

Nobody will scold me. The sooner I call, the better the chance of getting the money back.

The last line is required. Shame can keep a person silent for a full day, and that day can decide whether the money comes back.
