Ask an attorney how they charge and the answer arrives as a category, which sounds like a pricing preference and is really an allocation of risk. Every legal matter contains an unknown quantity of work, and the three common arrangements differ almost entirely in who absorbs that unknown. Once the question is put that way, choosing between them stops being about which sounds cheapest and becomes a straightforward decision about which side is better placed to carry the uncertainty in your particular situation.
Hourly, Where the Client Carries the Uncertainty
An hourly arrangement bills for time actually spent, usually in fractions of an hour, and it means that if the matter takes three times as long as anticipated the client pays three times as much. The attorney is compensated for the work regardless of how the matter turns out, which removes any pressure to cut corners and also removes any financial incentive to be quick. Rates vary widely by market and by seniority, and much of the work on any file is properly done by somebody billing less than the partner.
What makes hourly billing tolerable is visibility, and that means asking for two things at the outset. An estimate of the total range for the matter as described, with a commitment to be told when it is being exceeded rather than afterward. And itemized statements showing what was done, by whom, and for how long, monthly rather than at the end. A client receiving those can manage the cost as it accrues, which is the only point at which it can be managed.
Flat Fees, Where the Attorney Carries It Instead
A flat fee sets one price for a defined piece of work and shifts the risk of it taking longer onto the firm. It suits matters that are well bounded and repeatedly performed: a will, an incorporation, a residential closing, an uncontested filing, a document review. The client knows the number in advance, which is worth a real premium to most people, and the firm prices in enough margin to absorb the ones that run long.
The thing to examine is the boundary rather than the number. A flat fee for a filing may or may not include responding to a rejection, the government fees themselves, revisions after the first round, or anything that arrives once the matter becomes contested. That boundary should be written into the engagement letter in the same detail a contractor would use for a scope of work, and a firm that will not write it down is quoting a flat fee for something that is not actually flat.
Contingency, Where Nobody Pays Unless There Is a Recovery
A contingency fee is a percentage of what is recovered, payable only if something is recovered, and it exists because it is the only way most people could pursue a claim they could never fund hourly. The percentage commonly steps up as a matter progresses, since a case settled before filing consumes far less than one taken through trial, and that structure should be stated as a schedule rather than as a single figure. The arrangement is available only where there is money to recover, which is why it appears in injury, employment, and some consumer matters and never in defense work or in most family matters. The two questions that decide whether a particular offer is a good one are whether the percentage is calculated before or after costs are deducted, which changes the client’s share meaningfully, and what happens if the case is lost or dropped partway through.
The Retainer, Which Is Not a Fee at All
A retainer is frequently misunderstood as a purchase, and it is usually a deposit. Money paid up front sits in a trust account belonging to the client, and the firm draws against it as work is performed and billed, with the unused balance returned when the matter ends. A client who understands this can reasonably ask for the trust account statement and can expect the remainder back, which is a conversation that goes very differently when both sides know what the money is.
A smaller number of arrangements use the word differently, describing a monthly payment that buys availability or a defined amount of ongoing advice, which is a subscription rather than a deposit and is not refundable in the same way. Some jurisdictions restrict how a fee described as earned on receipt may be handled, precisely because the distinction has been abused. The engagement letter will say which one is meant, and it is worth reading that paragraph carefully rather than assuming, since the two behave nothing alike when a matter ends early and one of them produces a refund while the other does not.
Costs Are Not Fees, and the Engagement Letter Should Say So
Separately from whatever the attorney charges for time, a matter incurs costs: serving the papers, the reporter at a deposition, expert witnesses, records requests, travel, and whatever the court charges to accept a filing. These are generally the client’s responsibility under every fee structure including contingency, and on a litigated matter they can run to a substantial figure of their own. A client who has budgeted for the fee and not for the costs has budgeted for part of the matter.
Everything above should be settled before signature, in writing, in the engagement letter: the structure, the rate or percentage schedule, who else may work on the file and at what rate, how costs are handled and whether they are advanced, how often statements arrive, and what happens if either side ends the relationship. None of those questions is impolite and every competent firm expects them, because the arrangement that produces a good outcome is the one where both sides agreed in advance about which of them was carrying the unknown.
