You set up an inheritance wallet for your child, and then their phone is stolen. Your first reaction is to change the beneficiary right away. But does your inheritance plan allow changes at any time? The answer depends on the type of plan you use. Some plans can be changed with one click, while others require changing the whole wallet setup. There is a clear difference between "can change" and "can change safely."

Scenario A: You use a centralized exchange inheritance feature (such as Binance emergency contacts)
The benefit of this kind of plan is: you can add, delete, or change it at any time. You do not need to change anything on-chain.
[What to do]: Log in to the exchange dashboard, delete the compromised emergency contact, and add a new one.
[How to do it] (using Binance as an example):
Log in to the Binance App. Tap the bottom navigation to go to "Profile" (the avatar icon).
Tap "Account Security".
Find the "Emergency Contacts" entry.
In the list, delete the compromised old contact. Tap "Add New Contact" and enter the new contact's phone number or email. The other person must confirm the invitation within 24 hours.
After confirmation, the new contact takes effect and the old contact's permission is removed.
[Done when]: In the emergency contact list, the old contact's name is gone and the new contact shows "Confirmed" status. The exact path depends on the current App version.
Note: If you are the exchange account owner (and you are alive), this action is fully under your control. But if you are already unable to act, this process will not work when the heir's phone is stolen — because you cannot operate the account. So a stolen phone for an heir is really an event that you yourself must respond to immediately. It does not follow the logic of "the heir changes it themselves."
Scenario B: You use a plan like Bitkey with "inheritance claim + waiting period"
Bitkey's inheritance logic works like this: you set a beneficiary. That person can start a claim, and then a 6-month waiting period begins. During those 6 months, you receive alerts through multiple channels, and you can cancel the claim at any time.
What if the beneficiary's phone is stolen during the waiting period?
[What to do]: The beneficiary needs to reinstall the Bitkey App on a new phone immediately and restore the account.
[How to do it]: The beneficiary installs the Bitkey App on the new phone, then restores using the original account. This usually requires verification through the linked email or phone number. After logging back in, the claim status and waiting period progress remain the same. Bitkey clearly says: as long as the claim is still in the waiting period, the beneficiary can see the status in the App.
[Done when]: The beneficiary successfully logs in on the new phone, and the App shows "Inheritance claim started, XX days remaining."
But Bitkey only supports "one beneficiary," and the beneficiary needs to hold a hardware device. If the beneficiary's hardware wallet is stolen together with the phone, recovery becomes more complicated.
Scenario C: You use an on-chain multisig or smart contract inheritance plan
For these plans (such as Safe multisig or time-lock contracts), changing the beneficiary usually requires submitting an on-chain transaction.
[What to do]: Submit an on-chain transaction to change the beneficiary, then wait for signatures or the time lock to take effect.
[How to do it] (using multisig as an example):
Connect your wallet and enter the management interface.
Find the "Change Beneficiary" or "Replace Recovery Contact" function.
Enter the new address and submit the transaction.
If multisig is required, the other signers confirm.
The change takes effect after the transaction is on-chain.
[Done when]: You find the change transaction confirmed on a block explorer (status: Success), and the beneficiary address stored in the contract is updated to the new address.
Key warning: If changing the beneficiary requires the current beneficiary's signature, and that beneficiary's phone has just been stolen, you get a deadlock: you cannot change it because the old beneficiary cannot sign. So when setting up multisig, make sure changing the beneficiary does not require the beneficiary's own signature. This is a trap many people fall into when designing inheritance plans.
Common mistake: mixing up "device loss" and "account loss"
Losing a phone is not the same as losing an account. In most plans, the heir only needs to log in again on a new device (using email/phone verification + password) to recover all states in the App — including the inheritance claim progress.
But if the email password is also stored in the phone's notes, that is a different story. The real risk of a stolen device is not "the App is gone." It is that "passwords, seed phrase screenshots, and 2FA seeds are stolen together."
Risk reminder
After Bitkey approves an inheritance claim, your crypto app keys are released to the beneficiary. At that point, your wallet should be treated as no longer safe. If you are alive and the claim was accidental or malicious, Bitkey strongly recommends that you immediately stop using that wallet and create a new wallet with a new set of keys. This is not just about changing the beneficiary; the whole wallet needs to be migrated.
If your plan is this type (keys are released), and the heir's phone is stolen, what you need to do is not "change the beneficiary." Instead, immediately move the assets to another uncompromised wallet address, then set up the inheritance relationship again.

How to verify the change is complete
After changing the beneficiary, confirm at least two things:
Check the beneficiary address in the contract or dashboard: In the App or on a block explorer, check the currently stored beneficiary address and confirm it has changed to the new address.
Run a test once: If the plan allows, simulate "beneficiary starts a claim" in a test environment. Confirm that the new beneficiary can receive notifications and access normally, and the old beneficiary is completely removed.
It is recommended to check every 12 months that the beneficiary and emergency contact details in your inheritance plan are still valid — especially phone numbers. Forgetting to update a changed number is more common than a stolen phone.
