Offer law firm payment plans only after you decide where the money goes, what the agreement says and how long you will carry the balance. A client wants to hire your firm and cannot pay the full fee on day one. Saying yes helps that client, and it also creates a trust account question, a drafting question and, for longer plans, a lending question.
This guide covers the fee rules, trust account treatment, the federal lending test, a six-step setup, a sample schedule and immigration files. Rules vary by state, so treat each cited source as an example and check your own bar's version before you rely on it.
Key Takeaways
- A payment plan is a fee arrangement, so the fee must stay reasonable and its terms must be communicated to the client under Rule 1.5.
- Interest and late fees belong in the written agreement before they are charged. A 2026 Michigan Bar Journal article says terms left out are waived.
- An installment that pays for work not yet done is an advance fee that stays in trust until it is earned, in the sources reviewed.
- Regulation Z defines a creditor partly by more than four installments, so a long plan can raise a federal lending question for counsel.
- Set the down payment, the term and the missed-payment steps before launch. Immigration files add decisions about third-party payers, foreign currency and staged billing.
What Law Firm Payment Plans Are
A law firm payment plan is an agreement that lets a client pay a legal fee in scheduled installments instead of in full up front. The firm and the client set the amounts and the dates, and the firm itself is owed the balance.
Three nearby arrangements get mixed up with it. Fee financing sends the client to a third-party lender. An evergreen retainer keeps a standing balance in the trust account, and the client tops it up as the firm bills against it. Card on file stores a card that the firm charges for each invoice.
Compare them on who is owed the money, when the firm is paid and who carries the collection risk:
Are Payment Plans Allowed Under the Ethics Rules?
Yes, with the same limits that apply to any fee. Rule 1.5, shown here in the Minnesota version of the rule, says a lawyer shall not charge an unreasonable fee. It adds that the basis or rate of the fee must be communicated to the client, preferably in writing, within a reasonable time.
Interest and Late Fees Need Written Terms
Interest and late fees need more care than the installments themselves. A Michigan Bar Journal article by Alecia Chandler (April 2026) says interest and late fees must be in the agreement or they are waived. They also may not be illegal or usurious.
Colorado's bar association issued Opinion 66 (revised October 5, 2016). It says a lawyer may agree by contract to charge reasonable interest on unpaid fees. The lawyer may not impose it unilaterally.
Opinion 66 states that it does not address fees paid over time under an agreed payment plan. It guides late-fee terms and does not rule on plans. Find your own state bar's opinion before you put a rate in any agreement. A plan with no interest and no late fee skips this question. The lending section below shows why plan length can raise a different one.
Where Installment Payments Go: Trust or Operating Account
Once the agreement is settled, the next question is which account receives each installment. The answer depends on whether the payment covers work the firm has already done.
Unearned Fees Stay in Trust Until Earned
In its guide A Lawyer's Guide to Client Trust Accounts (2024), the State Bar of Texas says unearned fees and advance payments of expenses must go into a trust account. It adds that unearned fees are subject to refund until earned. Labeling a flat fee nonrefundable or earned on receipt does not change that.
Minnesota's Rule 1.15 takes the same approach for fees received in advance of the legal services. It directs the lawyer to deposit them in a trust account and withdraw them as earned.
An installment that pays for work the firm has not yet done fits that description. The safer practice is to deposit it in trust and withdraw it as the work is completed. Your state's rule controls, and our guide to trust accounting for law firms covers the account basics.
Earned Fees Go to the Operating Account
Fully earned fees go to the operating account, which the Texas guide describes as holding funds received in payment for work already performed. A late installment that pays down an invoice for finished work fits this description. The same guide notes that a lawyer may accept credit card payments, so the payment method does not change which account is correct.
Set Benchmarks in the Agreement
The Texas guide says a lawyer should assume no part of the fee is earned until the representation ends, unless benchmarks say otherwise. A plan therefore needs stated milestones, such as consultation complete, forms drafted and filing made, each tied to the portion of the fee it earns.
The agreement should also say how the unearned portion is calculated and returned if the client leaves midway. Minnesota's Rule 1.5 comment says a lawyer may require advance payment of a fee but must return any unearned portion.
Does a Payment Plan Make Your Firm a Lender?
Possibly, if the plan is long enough and the firm extends them regularly, so this is a question for your own counsel. Regulation Z, the federal Truth in Lending rule, defines a creditor in 12 CFR 1026.2(a)(17) as a person who regularly extends consumer credit. That credit must carry a finance charge or be payable by written agreement in more than four installments, not counting a down payment. The creditor is also the person to whom the obligation is initially payable.
Two parts of the text narrow the test. Consumer credit means credit offered primarily for personal, family or household purposes. A fee owed by a company for business purposes falls outside it. The same section says a person regularly extends consumer credit only after more than 25 extensions in the preceding calendar year. Credit secured by a dwelling has a lower count of five.
Whether a legal fee plan counts as credit at all, and whether your state's consumer credit laws use a different test, are questions for counsel. For plan design, the number of installments and the presence of a finance charge are the two levers, so set them on purpose. Check the current text of the regulation before you rely on the thresholds above.
When to Offer a Payment Plan and When to Say No
With the rules settled, the next decision is who gets a plan. A written eligibility test keeps the answer consistent from one client to the next. Offer one only when all of these are true:
- The client can name a monthly amount they can pay, and the plan ends within the longest term your firm allows.
- Your firm can carry the unpaid balance at the planned pace of work.
- The matter has a defined scope and a flat fee or a firm estimate, so installments can be scheduled.
- The client agrees to a standing payment method, such as autopay from a card or bank account.
Test affordability with plain division. A $3,600 fee at 150amonthruns24months(3,600 divided by $150). That is two years of carrying a balance on a matter that may be finished in a few months. In that case, raise the down payment, shorten the term, or decline the plan.
How to Set Up a Payment Plan in Six Steps
Once a client qualifies, six steps take a plan from policy to the first payment:
- Write the policy. State who qualifies, the longest term, the smallest down payment and the payment methods you accept.
- Choose the structure. A down payment plus equal installments with a fixed end date is the simplest shape to schedule and track.
- Write the agreement. Use the checklist below, and fold the plan into your retainer agreement so the client signs one document.
- Assign each payment to an account. Decide which installments go to trust and when portions move to operating, using the milestones in the agreement.
- Automate billing and reminders. A calendar can do it, though software that charges on schedule and sends a reminder before each due date removes manual work.
- Review each plan monthly. Compare the amount paid with the work completed, and contact the client before a grace period ends.
Sample Payment Plan Schedule
This illustrative schedule shows a $4,500 flat fee with a $1,500 down payment and six monthly installments of $500.
Suppose most of the work is finished by the end of month 2. The firm has been paid $2,500 and carries $2,000. A $2,500 down payment with four installments of $500 totals the same $4,500. By month 2 the firm has been paid $3,500 and carries $1,000. Moving money into the down payment is the cheapest way to cut the balance the firm carries.
What the Payment Plan Agreement Should Say
Every term below should appear in writing before the first payment is due:
- The total fee and what it covers, with costs and government fees on separate lines.
- The down payment and its due date.
- The installment amount, the due dates and the final payment date.
- The accepted payment methods, and the client's authorization for autopay.
- The account each payment goes to and the milestones at which portions are earned.
- The grace period and what happens when it ends.
- A late fee or interest, only if your state allows it, with the rate or amount stated.
- What happens to the work if payments stop.
- How an unearned balance is calculated and refunded if the client ends the engagement.
Payment Plans for Immigration Matters
Immigration files add three complications: other people paying, money arriving from abroad and cases that run in stages. The table lists the drafting decision each one forces and the question to put to your attorney.
Have an attorney who practices immigration review each scenario against your state's rules before it goes into a template.
When a Client Stops Paying
A plan needs a written answer for the missed payment before the first one is missed. ABA Model Rule 1.16 allows withdrawal when a client fails substantially to fulfill an obligation regarding the lawyer's services. The client must first have been given reasonable warning that the lawyer will withdraw unless it is fulfilled.
Rule 1.16(c) adds that a lawyer must comply with applicable law requiring notice to or permission of a tribunal when ending a representation.
This short ladder keeps the response consistent and builds the record that the warning requires:
- Send a reminder before the due date.
- Contact the client on the first missed payment and offer to adjust the schedule inside the grace period.
- Send a written warning after the grace period that states the amount owed and the date.
- Check every filing deadline on the matter, so a payment dispute does not cause a missed deadline for the client. Then decide whether to renegotiate, pause work as the agreement allows, or prepare to withdraw.
- Withdraw only after the rules and any tribunal requirements are met.
Choosing Tools for Payment Plans
Software can carry the schedule, and the same rules still decide which account receives each payment. Look for these features:
- Recurring charges by card and bank transfer on a schedule you set.
- Separate handling of trust and operating funds.
- A reminder before each due date and an alert when a payment fails.
- A report that shows each plan's paid and unpaid balance.
US Immigration AI's AI Payment Collection splits fees into weekly or monthly installments, sends retainer money to the trust account and alerts the firm when a client's funds run low. Whatever tool you pick, test one full plan from signing to final payment before you offer it to clients.
How to Tell Whether Payment Plans Are Working
Set a baseline before launch, then review these four measures each quarter:
- Collection rate on plan balances.
- Days from signing to final payment.
- Share of plans with a payment missed past the grace period.
- Unpaid balance at the time of filing.
A rising unpaid balance at filing points to a down payment that is too small. If more plans miss a payment past the grace period, the term is probably too long or the eligibility test too loose.
