Law firms routinely handle client funds, which requires strict adherence to ethical standards and regulatory guidelines. Two primary mechanisms govern how these funds are held: IOLTA accounts and escrow accounts.
Each serves distinct purposes under specific regulatory frameworks, and choosing between them (or using both) requires a clear understanding of their nuances, obligations, and practical applications.
This post provides a detailed comparison of these options, discussing their definitions, operational details, compliance requirements, and benefits. The goal is to help your firm decide which approach best fits your needs when handling client money.
Overview of Trust Accounts in Law Firms
Trust accounts are a cornerstone of financial management in legal practice, designed to segregate client funds from a law firm’s operating capital. This separation is not just a best practice, it’s a professional and ethical mandate under state bar rules.
By isolating client money, trust accounts safeguard against misuse, ensure accurate disbursement, and uphold the fiduciary duty attorneys owe their clients. They also facilitate compliance with state bar audits and protect firms from disciplinary action or liability.
Two primary types of trust accounts dominate this framework, each tailored to distinct purposes and fund characteristics:
- IOLTA Accounts: Used for small or short-term funds that do not generate significant interest individually.
- Escrow Accounts: Used for larger sums or funds that remain in trust over longer periods, where interest accrual can be directly attributed to the client.
IOLTA Accounts Explained

An IOLTA account, or Interest on Lawyers’ Trust Account, is a pooled trust account designed to hold client funds that are nominal in amount or expected to be held for a short duration.
The defining feature of IOLTA is that the interest earned on these accounts is remitted to state bar associations or designated charitable entities, typically to fund legal aid for underserved populations.
Established under state-specific rules and aligned with the American Bar Association’s Model Rules of Professional Conduct, IOLTA programs are mandatory in most jurisdictions for certain types of client funds.
Law firms typically use IOLTA accounts for advance fee payments, retainers, or settlement proceeds awaiting disbursement when the sums or holding periods don’t justify a separate interest-bearing account.
For example, a $2,000 retainer held for two months falls squarely within IOLTA’s scope. The benefits are straightforward: compliance with ethical obligations is streamlined, administrative overhead is minimal, and the pooled interest supports access to justice initiatives.
However, IOLTA accounts lack flexibility—funds must meet strict criteria for nominality or brevity, and clients don’t receive interest, which can limit their utility in certain cases.
Understanding Escrow Accounts
Escrow accounts, by contrast, are trust accounts established to hold client funds for specific purposes, often tied to a transaction or longer-term arrangement.
Unlike IOLTA, escrow accounts are not inherently linked to charitable interest allocation; instead, any interest earned typically accrues to the client or parties designated by the underlying agreement.
These accounts are common in real estate closings, business deals, or litigation settlements where funds must be held securely until conditions are met.
Firms practicing in transactional law, such as real estate, mergers and acquisitions, or estate planning, frequently rely on escrow accounts. For instance, a $50,000 earnest money deposit for a property sale would be held in escrow until closing.
Escrow offers significant flexibility: the account can be tailored to the transaction’s needs, and holding periods can extend from weeks to years. However, this adaptability comes with a trade-off: greater administrative responsibility.
Firms must ensure precise documentation, often involving third-party escrow agents, and comply with fiduciary duties under state law and contract terms.
The benefits include enhanced client trust and the ability to manage substantial sums without IOLTA’s restrictions. Challenges arise in the form of setup costs, potential fees for third-party oversight, and the need for rigorous tracking to avoid errors or disputes.
IOLTA vs Escrow Accounts

Understanding the differences between IOLTA and escrow accounts is essential for law firms managing client funds. While both serve as trust accounts, they operate under distinct rules and purposes.
Below, we’ll compare key aspects of IOLTA and escrow accounts, including their intended use, compliance requirements, and how law firms should handle each to maintain ethical and legal standards.
Compliance
IOLTA is mandated by state bar rules for qualifying funds, whereas escrow is governed by contractual obligations and fiduciary standards.
Compliance involves opening accounts with approved banks, ensuring interest is remitted to the state program, often with annual reporting to bar authorities. Failure to adhere risks disciplinary measures, as state oversight is rigorous.
Escrow accounts fall under a different regulatory framework, governed by contractual terms and the attorney’s fiduciary duty rather than a universal mandate. Depending on the jurisdiction and transaction, escrow may also face oversight from banking regulators or third-party agents, adding layers of complexity.
Firms must draft precise escrow agreements, maintain detailed ledgers, and ensure funds align with client instructions, balancing ethical obligations with case-by-case variability that contrasts with IOLTA’s standardized requirements.
Client Protection
IOLTA accounts provide an added layer of protection for clients, ensuring their funds are managed with the utmost care and transparency. This fosters trust and confidence in the attorney-client relationship, as clients can be assured that their funds are being managed in a manner that is both ethical and transparent.
By participating in the IOLTA program, law firms can demonstrate their commitment to client protection and their participation in a program that enhances access to justice. This commitment to ethical financial management is essential for maintaining client trust and ensuring the success of the IOLTA program.
Escrow accounts achieve client protection through individualized management, ensuring funds remain intact and accessible for their intended purpose, with interest credited directly to the client or designated parties.
This setup promotes transparency and trust. Ethically, escrow demands meticulous record-keeping and adherence to fiduciary standards, offering a bespoke safeguard that complements IOLTA’s broader, systemic approach to financial integrity.
Account Setup Protocol
IOLTA account setup follows a uniform, state-driven protocol. Firms must select a financial institution approved by their state’s IOLTA program, register the account under the firm’s tax ID with an explicit “IOLTA” label, and notify the state bar of its establishment.
This process ensures compliance with rules like ABA Model Rule 1.15, with funds tracked via trust accounting software and reconciled monthly to catch discrepancies early. Best practices include segregating client ledgers, retaining records for five to seven years per audit requirements, and training staff on trust account obligations.
Escrow account setup, by contrast, is case-specific and less standardized. Firms can open a dedicated account with a bank or enlist a third-party agent—such as a title company—depending on the transaction’s needs, like a real estate closing.
The escrow agreement, crafted with client input, dictates terms, interest allocation, and release conditions, demanding more customization than IOLTA’s plug-and-play approach. Management relies on tools like Clio Manage or TrustBooks, with detailed tracking and client communication as non-negotiable best practices, reflecting escrow’s higher administrative burden.
Fund Management Rules

Both IOLTA and escrow accounts demand meticulous fund management, but their rules diverge in scope.
IOLTA requires prompt deposits of nominal or short-term funds, prohibits commingling with firm capital, and mandates robust internal controls, like monthly reconciliations and preprinted deposit slips, to ensure transparency.
These measures align with state bar oversight, protecting client assets while channeling interest to public programs, which is a key distinction from escrow’s client-focused model.
Escrow fund management prioritizes individualized control, with firms tailoring practices to each account’s purpose. Record-keeping must track deposits, withdrawals, and interest accrual per client instructions, often under contractual rather than universal regulatory mandates.
While both require precision, escrow’s flexibility contrasts with IOLTA’s rigid structure, necessitating adaptable systems to handle varied timelines and larger sums without the safety net of state-prescribed protocols.
Account Segregation
Segregation is non-negotiable for IOLTA accounts, where client funds must remain distinct from firm operating accounts to comply with ethical standards and protect against misuse.
A firm managing multiple $1,500 retainers, for example, keeps each client’s balance in a single IOLTA account with separate ledgers, ensuring clarity for audits and reinforcing the program’s integrity. This contrasts with escrow’s more modular segregation, tied to individual matters rather than a collective pool.
Escrow accounts also mandate segregation, but on a per-transaction basis, like a $200,000 business deal deposit isolated from other client funds and firm money, for instance.
This case-specific separation offers precision over IOLTA’s broader pooling, allowing firms to align funds with client expectations, like interest accrual, while still upholding fiduciary duty. Both systems prevent commingling, yet escrow’s granularity provides a tailored safeguard absent in IOLTA’s standardized design.
Record-Keeping Requirements

Proper documentation is the cornerstone of managing trust accounts effectively. For IOLTA accounts, law firms must maintain comprehensive records of all client transactions—each deposit, withdrawal, and interest entry should be documented thoroughly.
This documentation serves as evidence of compliance with state regulations and provides clients with clear insights into how their funds are managed.
In escrow accounts, detailed documentation is equally critical. Every transaction must be recorded, and the escrow agreement should clearly outline the conditions for interest allocation and fund release.
Maintaining up-to-date records not only supports regulatory oversight but also ensures that any questions from clients or auditors can be addressed quickly and accurately. In both models, robust documentation practices enhance transparency and reinforce the firm’s commitment to ethical financial management.
Choosing The Right Account for Your Firm
The decision rests on three factors: practice type, fund size and duration, and regulatory requirements. Litigation-focused firms with frequent small retainers lean toward IOLTA.
Transactional practices handling large, client-directed sums favor escrow. Firms straddling both may maintain separate accounts to cover all bases. Consulting state bar guidelines or a financial advisor clarifies obligations, especially in jurisdictions with unique IOLTA thresholds.
Firms should also consider growth. A startup may rely solely on IOLTA, but expanding into real estate or complex litigation could necessitate escrow capabilities. Periodic reassessment ensures alignment with evolving needs.
Key questions guide the decision: How long will the funds be held? Who is entitled to the interest? What do state regulations dictate? Answering these aligns the firm’s choice with legal and practical realities.
Here are three scenarios:
- Small Firm with Retainers: A solo practitioner receives a $1,500 retainer for a divorce case expected to last three months. State rules require nominal funds to be placed in an IOLTA account. The firm complies, deposits the money, and disburses it as earned, with interest supporting local legal aid.
- Real Estate Law Firm: A firm handling a commercial property sale receives a $100,000 deposit from the buyer. The funds must remain secure until closing in six months, and the purchase agreement specifies that interest accrues to the buyer. An escrow account, managed by the firm or a title company, is the appropriate vehicle.
- Mixed Practice: A mid-sized firm handles both litigation and transactional matters. Retainers for personal injury cases go into IOLTA, while settlement funds for a business acquisition are held in escrow pending final terms. This dual approach ensures compliance and client satisfaction across practice areas.
Common Mistakes to Avoid
IOLTA pitfalls include failing to reconcile accounts monthly, misjudging “nominal” funds and placing them outside IOLTA, or inadvertently commingling firm earnings with client money. Each error invites bar scrutiny.
Escrow missteps involve ambiguous agreement terms, delayed disbursements due to poor tracking, or neglecting to follow client instructions on interest, which can erode trust or trigger disputes.
Mitigation requires discipline: automate reconciliations where possible, document every escrow transaction, and conduct annual trust account reviews. Training staff on trust accounting principles further reduces exposure.
IOLTA Account vs Escrow Account: Key Takeaways

In summary, both IOLTA and escrow accounts are essential tools for managing client funds in law firms, each with its own advantages and use cases. IOLTA accounts offer a collective approach that supports public legal services, making them ideal for handling smaller or short-term funds.
Escrow accounts, on the other hand, provide a client-specific approach, ensuring that any accrued interest benefits the client directly.
When deciding between these two options, law firms should consider factors such as the size of the funds, the expected duration of the deposit, and the desired method of interest allocation.
By understanding the regulatory requirements and best practices for both account types, firms can maintain ethical standards while choosing the model that best meets their operational needs.
