How Do You Set Up Your Law Firm's Bank Accounts?

Opening bank accounts feels like a mundane administrative task, but for a law firm it is one of the more consequential setup decisions you will make. The way you structure your accounts, and above all how you separate client money from firm money, sits at the heart of one of the profession's most serious ethics obligations. Get it right and trust compliance becomes routine. Get it wrong and you expose yourself to commingling, one of the fastest paths to discipline.

This is general information, not legal advice, and trust-accounting rules vary by state, so confirm your own jurisdiction's rules. With that framing, this article covers what accounts a law firm needs, what a client trust account is, how to choose a bank, and how to keep the whole structure clean so your firm's finances start compliant and stay that way.

How Do You Set Up Your Law Firm's Bank Accounts?

Open at least a business operating account and a separate client trust account, keep them strictly separate, and use a bank that properly supports attorney trust accounts. The non-negotiable principle is that client money and firm money live in different accounts and never mix.

Your operating account holds the firm's own money, the earned fees and funds you use to run the business, while your client trust account holds money that belongs to clients until it is earned or spent. Setting these up correctly at the start, with a bank equipped for legal trust accounting, establishes the separation that your ethics rules demand. Many solos also add a savings account for taxes and reserves. The core of the setup, though, is the clean, absolute division between operating and trust funds, which is the foundation everything else rests on.

Why Do Your Bank Accounts Matter So Much?

Because commingling client and firm funds is one of the most serious ethics violations, and your account structure is what prevents it. The separation of client money from firm money is a bedrock obligation, and it lives or dies at the level of your bank accounts. If the accounts are structured wrong, compliance is nearly impossible; if they are structured right, it becomes manageable.

Trust-accounting violations, including commingling and mishandling client funds, appear constantly on discipline dockets, often from attorneys who never intended to do anything wrong but set up or managed their accounts carelessly. Because the stakes are this high, your bank account setup is not a clerical detail but a compliance decision. Getting it right from the start, with clearly separated accounts and a proper bank, is one of the most important protective steps a new solo can take.

What Accounts Does a Law Firm Need?

At minimum an operating account and a client trust account, often with a savings account as well. Each serves a distinct purpose, and keeping them separate is what maintains the divisions your practice requires:

• Operating account: holds the firm's own money, earned fees and funds for running the business and paying expenses.
• Client trust account: holds money that belongs to clients, such as unearned fees and cost advances, until earned or spent.
• Savings or reserve account: optional but useful, for setting aside taxes and building a cash cushion.

The operating and trust accounts are essential and must be kept rigorously separate, while a savings account is a practical addition for financial discipline. Establishing these at launch gives every dollar in your practice a proper home.

What Is a Client Trust Account?

It is a separate account that holds money belonging to clients, kept apart from your firm's funds, often structured as an IOLTA account. When clients pay unearned fees or provide funds for costs, that money is not yours yet; it belongs to them until earned or spent, and it must be held in a client trust account rather than your operating account.

In many jurisdictions, client funds that are small in amount or held briefly go into a pooled trust account known as an IOLTA account, where the interest is directed to a legal-services program rather than to you or the client. The specifics of how trust accounts and IOLTA work vary by state, so confirm your rules. The essential point is that the trust account is a distinct, protected place for client money, governed by strict rules about what can go in, what can come out, and how it must be tracked and reconciled.

How Do You Choose a Bank?

Pick a bank that properly supports attorney trust accounts and does not let its fees touch client funds. Not every bank is set up for the particular requirements of legal trust accounting, so choosing one that is avoids problems from the start. Many jurisdictions maintain lists of approved institutions for trust accounts, which is a good place to begin.

Look for a bank experienced with attorney trust and IOLTA accounts, one that handles the required interest arrangements and reporting correctly. Critically, ensure the bank does not deduct its fees or charges from the client funds in your trust account, since that could create a shortfall in client money, a serious problem; account fees should come from your operating account instead. Reasonable overall fees and good service matter too, but the trust-accounting capabilities are the decisive factor. A properly chosen bank makes trust compliance far easier.

How Do You Keep Trust and Operating Funds Separate?

Never mix the two, and never pay firm expenses from the trust account. The separation is only as good as your discipline in maintaining it, so the operational rules matter as much as the account setup. Client money goes into trust and stays there until properly earned or disbursed; firm money stays in operating.

Concretely, this means you never pay business expenses from the trust account, never deposit firm funds into it beyond any small amount permitted to cover bank fees where allowed, and move earned fees from trust to operating only once they are actually earned and by the proper process. Maintain a ledger for each client's trust funds and reconcile the trust account regularly, typically monthly. These practices, built on the separated account structure, are what keep you compliant day to day. The setup enables separation; your habits maintain it.

How Do You Set Up for Clean Bookkeeping?

Connect your accounts to a bookkeeping system that tracks trust and operating funds distinctly and supports reconciliation. Your bank accounts are the foundation, but they only stay compliant if your recordkeeping keeps pace, so set up your books alongside your accounts rather than as an afterthought. Clean accounts with sloppy records still lead to problems.

Use accounting or practice management software, ideally legal-specific, that maintains individual client trust ledgers, keeps trust and operating transactions separate, and makes the regular three-way reconciliation of your trust account straightforward. Linking your accounts to such a system from the start means every transaction is recorded correctly and your trust account can be reconciled reliably. The combination of properly separated accounts and disciplined, law-firm-appropriate bookkeeping is what turns trust compliance from a source of anxiety into a routine part of running your firm.

Set Up Right, Stay Compliant

Your law firm's bank accounts are a compliance decision, not just an administrative one. Open a separate operating account and client trust account, use a bank that properly supports attorney trust accounts and keeps its fees off client funds, never mix the two, and pair the setup with disciplined, law-firm-appropriate bookkeeping and regular reconciliation. Get this right at launch and you build your firm on a foundation that keeps one of your most serious obligations under control.
