7.2 Billing Clients, Retainers, Contingent & Forwarding Fees, Collection Charges & Advances
Key Takeaways
- A general or classic retainer is earned on receipt for availability, while an advance fee retainer is unearned client money that must be deposited in trust until the fee is earned.
- Model Rule 1.5 forbids an unreasonable fee and requires that a contingent fee be in a writing signed by the client, stating the percentage, how expenses are handled, and whether the percentage is computed before or after expenses.
- Contingent fees are prohibited in domestic relations matters tied to securing a divorce or the amount of alimony or support, and in criminal defense representation.
- A forwarding or referral fee between lawyers not in the same firm requires proportional division or joint responsibility, client agreement to the arrangement in writing, and a reasonable total fee.
- Costs advanced on a client's behalf are recorded to the matter as a receivable and reimbursed, and they are conceptually distinct from fees for professional services.
7.2 Billing Clients, Retainers, Contingent & Forwarding Fees, Collection Charges & Advances
[!NOTE] NALS PP Exam Blueprint Focus: The Part 2 outline lists handling retainers, contingent fees, forwarding fees, and collection charges as one enumerated subtopic and recording advances made on behalf of clients as another. The classification questions here have direct ethical consequences under Part 3, because how a payment is classified determines which bank account it must go into.
Fee Structures
| Structure | How the fee is computed | Typical use |
|---|---|---|
| Hourly | Rate times time recorded | Litigation, ongoing corporate work |
| Flat or fixed | One agreed price for a defined scope | Wills, incorporations, uncontested matters, traffic defense |
| Contingent | Percentage of recovery, paid only on success | Plaintiff personal injury, some collections |
| Blended rate | One rate for all timekeepers regardless of seniority | Volume institutional clients |
| Capped or collared | Hourly, subject to a ceiling | Clients needing budget certainty |
| Value or task-based | Priced by outcome or by defined task | Transactional and regulatory work |
Every structure is subject to the same ceiling: Model Rule 1.5(a) prohibits an unreasonable fee. The rule lists the factors, including the time and labor required, the novelty and difficulty of the questions, the fee customarily charged in the locality, the amount involved and the results obtained, the nature and length of the professional relationship, and the experience and ability of the lawyer.
Retainer Types — the Classification That Decides the Bank Account
This is the single most tested distinction in law-office financial procedure, because misclassifying a payment puts money in the wrong account and produces an ethical violation independent of any dishonesty.
| Retainer type | What the client is paying for | Earned when? | Which account? |
|---|---|---|---|
| General or classic retainer | The lawyer's availability and the exclusion of adverse engagements | On receipt | Operating |
| Advance fee retainer | Future services not yet performed | As services are performed | Trust, transferred to operating as earned and billed |
| Special retainer | A specific identified matter, often a flat fee | Per the agreement, commonly as performed | Trust unless genuinely earned on receipt |
| Evergreen retainer | A minimum trust balance the client must replenish | As services are performed | Trust |
| Cost advance or deposit | Anticipated filing fees, expert fees, transcripts | Never earned as a fee — it is spent on costs | Trust |
[!WARNING] The most common law-office trust violation is a classification error, not a theft. A paralegal who deposits a $7,500 advance fee retainer into the operating account has caused the firm to hold client funds in a firm account. The remedy is immediate correction and, in most jurisdictions, notification under the applicable trust-accounting rule. Where a jurisdiction permits a nonrefundable fee earned on receipt at all, it typically requires clear written disclosure to the client.
A replenishing or evergreen arrangement obliges the client to restore the trust balance to a floor whenever it drops below it, and it is common in commercial litigation where cost exposure is unpredictable.
Contingent Fees
A contingent fee is paid only if the matter succeeds. Model Rule 1.5(c) imposes specific formalities:
- The agreement must be in a writing signed by the client.
- It must state the method of calculating the fee, including the percentage or percentages that accrue in the event of settlement, trial, or appeal.
- It must state which litigation and other expenses are to be deducted from the recovery.
- It must state whether expenses are deducted before or after the contingent fee is calculated — the ordering that determines how much the client actually receives.
- At conclusion, the lawyer must provide a written statement showing the outcome and, if there is a recovery, the remittance to the client and how it was determined.
The ordering point is worth working through numerically. On a $150,000 recovery with a one-third fee and $18,000 in expenses:
| Method | Fee | Expenses | Client receives |
|---|---|---|---|
| Fee computed before expenses | $50,000 | $18,000 | $82,000 |
| Fee computed after expenses | $44,000 | $18,000 | $88,000 |
The $6,000 difference is why the writing must specify the ordering. A paralegal preparing a settlement statement must apply the ordering the signed agreement actually uses.
Model Rule 1.5(d) prohibits contingent fees in two categories:
- Domestic relations matters where the fee is contingent on securing a divorce or on the amount of alimony, support, or a property settlement in lieu of them.
- Criminal defense representation.
Collection of an already-liquidated past-due support obligation is generally treated differently from a fee contingent on the amount of an award, and jurisdictions vary; the safe exam answer is that a fee tied to obtaining the divorce or setting the support amount is prohibited.
Forwarding and Referral Fees
When lawyers who are not in the same firm divide a fee, Model Rule 1.5(e) requires all three of the following:
- The division is in proportion to the services performed by each lawyer, or each lawyer assumes joint responsibility for the representation;
- The client agrees to the arrangement, including the share each lawyer will receive, and the agreement is confirmed in writing; and
- The total fee is reasonable.
A bare forwarding fee paid for nothing but the referral, without joint responsibility and without the client's written-confirmed agreement, does not satisfy the rule. Separately, Model Rule 5.4 prohibits sharing legal fees with a non-lawyer, which is why a referral fee cannot be paid to a paralegal, an investigator, or a marketing consultant.
Collection Charges and Interest
A firm may charge interest or a late fee on overdue balances only if the client agreed in advance, ordinarily in the engagement letter, and only within the limits of applicable usury and consumer-protection law. Two further constraints apply:
- Withdrawal for nonpayment is governed by Model Rule 1.16 and, in litigation, by the court's permission; a lawyer may not simply stop working.
- Suing a client for fees invites a malpractice counterclaim and requires the lawyer to disclose otherwise-confidential information only to the extent necessary under the Rule 1.6 self-defense exception.
Recording Advances Made on Behalf of Clients
A cost advance is money the firm spends on the client's behalf: filing fees, service of process, deposition transcripts, expert fees, court reporters, travel, records retrieval.
| Fees | Costs advanced | |
|---|---|---|
| What it is | Payment for professional services | Reimbursement of money laid out for the client |
| Accounting treatment | Revenue when collected | A receivable from the client when advanced |
| Bill presentation | Separate section for professional services | Separate section for disbursements |
| Markup | Reflected in the rate | Billed at actual cost; marking up a disbursement without disclosure is an unreasonable-fee problem |
Model Rule 1.8(e) governs financial assistance to a client in connection with litigation: a lawyer may advance court costs and expenses of litigation with repayment contingent on the outcome, and may pay those costs outright for an indigent client. Advancing living expenses is the prohibited category.
Every advance must be recorded to the specific matter at the time it is made. A cost paid from petty cash, a firm credit card, or the operating account that is never coded to a matter is a cost the client will never be billed for, and it disappears into overhead.
The Bill Itself
A defensible invoice contains:
- Client and matter identification, and the billing period.
- Professional services: date, timekeeper, narrative description, time, rate, amount.
- Disbursements: date, description, amount, itemized separately from fees.
- Trust account activity: beginning balance, deposits, disbursements, ending balance, where trust funds are involved.
- Prior balance, payments received, current charges, and amount due.
Bills go out on a regular cycle. Irregular billing is the leading cause of fee disputes, because a client who receives no invoice for five months receives one invoice that looks enormous.
A client pays a firm $12,000 described in the engagement letter as a deposit against hourly fees for an upcoming trial. Where must the paralegal direct the deposit, and when may any portion move?
A personal injury matter settles for $150,000. The signed contingent fee agreement provides for a one-third fee and states that litigation expenses are deducted before the fee is calculated. Expenses total $18,000. What does the client receive?
A solo practitioner refers a complex products liability case to a larger litigation firm and expects a share of the eventual fee. Which arrangement satisfies Model Rule 1.5(e)?
