Account Agreement

An account agreement is the written contract a bank or credit union gives a customer when they open a deposit or credit account, setting out the fees, interest terms, dispute procedures and other rules that govern how the account works. It is also commonly called a deposit account agreement or, for a card, a credit card account agreement, and it is the document a customer agrees to simply by opening and using the account, even without separately signing every page of it.

The agreement typically incorporates by reference a separate fee schedule and a periodic disclosure of changes, since banks are allowed to amend most terms with advance notice rather than renegotiating from scratch every time a market condition shifts. Regulators in most countries require certain disclosures to be given in the account agreement itself, such as how interest is calculated, what happens on an overdraft, and how a customer can close the account.

Most people never read the full account agreement they technically accept when opening a bank account, but it is the rulebook the bank actually follows whenever a dispute arises. Think of it as the fine print version of a handshake deal: the bank promises certain services and protections, and in exchange the customer agrees to certain fees and conduct rules, most of which only matter the day something goes wrong, such as a fraudulent charge or an unexpected fee.

• Fees for maintaining the account, falling below a minimum balance, or using services such as wire transfers or stop payments.
• How and when the bank can change the agreement's terms, and the notice period required before a change takes effect.
• The bank's liability rules for unauthorized transactions and the customer's duty to report errors promptly.
• Rules for joint ownership, powers of attorney and what happens to the account if the holder dies.

The account agreement works alongside separate regulatory disclosures. In the United States, for example, the Truth in Savings Act requires standardized disclosure of annual percentage yield figures, while electronic transfers are separately governed by rules implementing the Electronic Fund Transfer Act. Many jurisdictions also require a short-form summary of key terms up front, with the full agreement available on request, precisely because the complete legal text can run to dozens of pages that few customers read in full before opening an account.

Because an account agreement can be amended unilaterally within the limits set by consumer protection law, the practical bargaining power sits mostly with the institution rather than the individual customer. Customers retain the right to close the account rather than accept a disliked change, and in some jurisdictions a bank must give a set number of days' notice, commonly 30, before a fee increase or a materially adverse change takes effect. Disputes over an account agreement are usually resolved first through the bank's internal complaints process and, if unresolved, through a banking ombudsman or financial complaints authority such as the Australian Financial Complaints Authority or an equivalent body elsewhere.

The account agreement is the single reference point for resolving almost any dispute about how an account is supposed to work, from a disputed overdraft fee to the bank's right to freeze an account under suspicion of fraud. Reading the fee schedule and the sections on liability and dispute resolution before opening an account is the most direct way a consumer can avoid surprises later, and comparing agreements across banks before switching can reveal meaningful differences in how generously each institution treats errors and disputes.

Consumers considering switching banks are generally advised to compare the fee schedules and liability provisions in each institution's account agreement side by side, since a bank advertising a lower headline fee can sometimes offset that with less generous dispute-resolution terms elsewhere in the same agreement.
