The check you write at the start of a divorce case is not a payment. It is a deposit, and in nearly every state it goes into a client trust account that the firm may not touch until work has actually been done. That distinction matters more than most people realize on the day they sign, because it determines who owns the money, what happens to the unused portion, and what you are entitled to see each month. The invoice that arrives four weeks later is the accounting for it. Reading that invoice properly is the single cheapest thing a client can do.
The trust account, and why the balance is still yours
State bar rules require attorney trust funds to be kept separate from the firm's operating account, and interest on pooled client funds typically goes to a state program rather than to the firm or to you. Money moves from trust to the firm only when it has been billed and earned. That means an unearned balance remains your property, refundable if you change attorneys or settle early. Ask, before signing, whether the retainer is described as refundable, and whether the engagement letter uses the phrase "advance fee deposit" or something vaguer. The wording controls the refund.
A flat, nonrefundable "engagement fee" is a different animal and is treated differently under state ethics rules. Some jurisdictions permit it in narrow circumstances, some restrict it sharply. If a fee agreement mixes both, a nonrefundable piece plus a trust deposit, ask which portion is which in dollars, and get that answer in the document rather than in conversation. The Federal Trade Commission oversees unfair and deceptive billing practices in consumer transactions generally, but the operative rules here are your state's, and they are unusually specific about what an attorney must hold in trust.
Six minutes at a time
Most family law firms bill in tenths of an hour, six minutes, and round up. A two-minute email is billed at 0.1. Four such emails in a day become 0.4, which at a $400 rate is $160 for perhaps nine minutes of actual reading. This is not fraud, it is the standard convention, and it is why consolidating your questions into one message a week rather than five a day changes the invoice measurably. Some firms bill in quarter hours, which compounds the effect. Ask which increment applies, because the fee agreement will say and few clients look.
The entries themselves should be specific enough to audit. "Attention to file, 1.4" tells you nothing and is worth a question. "Review opposing counsel's response to request for production, draft deficiency letter, 1.4" tells you what you bought. Block billing, where several tasks are collapsed into one long entry, hides the allocation and makes it impossible to tell whether the two hours went to the deposition prep or to a scheduling call. Requesting itemized entries is a normal request and most firms will accommodate it without friction.
Who is actually doing the work
A partner's rate, an associate's rate, and a paralegal's rate can differ by a factor of three or more. That spread works in your favor when routine tasks are pushed down: assembling exhibits, indexing bank statements, preparing the financial affidavit's supporting schedules, calendaring deadlines. It works against you when a partner bills their rate to organize documents. Check who is signed against each line. Also watch for two attorneys attending the same hearing or conference, both billing. Sometimes that is justified by a genuine division of labor, and sometimes it is training time you are funding.
Replenishment clauses and the shift in leverage
Most agreements require you to top the trust balance back up when it falls below a threshold, often a fixed dollar figure or a fraction of the original deposit. The clause is reasonable on its face and gives the firm working capital. What it also does is set the point at which you will be asked for more money, and that point may arrive during trial preparation, when withdrawing would be expensive and disruptive. Knowing the trigger amount in advance lets you budget toward it and gives you time to compare, rather than deciding under pressure.
What to question, and what simply costs money
Worth questioning: vague entries, duplicated attendance, clerical work billed at professional rates, charges for the firm's own internal file administration, and time spent educating a newly assigned associate on a case you have already paid to have learned. Not worth questioning, because they are unavoidable: filing fees, court reporter and transcript costs, process server charges, mediator time, and the hours a genuine discovery dispute consumes. Raise concerns in writing within the period the agreement specifies, usually a set number of days after the invoice date, and be specific about the line and the number.
An attorney who bills honestly will expect the questions and answer them without defensiveness. The clients who spend least are rarely the ones who fought hardest over a single entry; they are the ones who read every invoice on arrival, kept their questions batched, and understood from the first month exactly where the deposit stood.
