Ask what the bank wants
Some banks have their own forms. Others accept a letter with your name, account number, request and signature. Ask whether they need an original, whether a scan will do, and which notarial act they want. Many also want a copy of your ID.
A phone call before the notary visit often saves a second trip.
Writing the letter
State your name as it appears on the account, the last digits of the account number, what you are asking the bank to do and the date. Keep it brief and polite. Sign only in front of the notary.
Never write your full account number on documents that others will handle if the bank gives another option.
What the notary does
The notary checks your ID, confirms you are signing willingly and completes a certificate, usually an acknowledgment. The notary does not confirm the account or contact the bank. If there are two account holders, each signs.
If the bank wants a signature stamp, that is a separate service from a financial institution, not a notary.
Third-party requests
If someone will act for you, such as a child helping a parent, the bank may want a power of attorney on its own form. A letter alone might not be enough. Ask the bank whether it accepts outside powers of attorney.
If the account holder has died, separate documents apply.
Sending it safely
Use a trackable method. Keep a copy of the letter, the notary certificate and the tracking receipt. Follow up in the days after. If the bank rejects the letter, ask for the reason in writing and adjust.
Remote online notarization may suit people who cannot leave home.
Scenario: moving and changing an address
A customer moves and her bank requires a signed and notarized address change for an account that has been dormant for years. She writes a short letter stating her name, the last four digits of the account, the old and new addresses, and a request to update.
She signs before a notary and mails the letter along with a copy of her ID. The bank confirms by mail to both addresses. Later, she sets up online access.
If the bank also holds a safe deposit box or trust account, check whether those need separate paperwork. Ask for a written confirmation when the change is complete so you have proof if a statement goes astray.
Keep your communications tidy. Write down the name of the representative you spoke to, the date, and what was promised. If the bank later says it never received the letter, a record of tracking numbers and call notes speaks louder than memory. Banks also update rules over time, so ask for the current requirements each time, not only the first time.
