A contingency percentage is only the first deduction; case costs, medical liens, and health insurer subrogation all take their turn before the check reaches you.

The number that sticks in a client's head is the one on the first page of the fee agreement, usually a third, sometimes forty percent, occasionally something lower for a straightforward claim. The number that matters is the one at the bottom of the disbursement sheet months or years later, after the fee, the advanced costs, the medical liens, and the health plan's reimbursement claim have all taken their turn. Those two numbers are related, but not closely. Reading the second one properly starts with reading the first one properly, before anything has been signed and while questions are still cheap.
Most contingency agreements carry tiers, and the tier that applies depends on how far the case travels. A common arrangement is one rate if the claim resolves before a lawsuit is filed, a higher rate once a complaint goes on the docket, and sometimes a third step if the case reaches trial or is appealed. The reason is simple enough: filing suit turns a negotiation into litigation, with depositions, motions, and expert work attached. What a careful reader checks is the trigger. Does the higher rate attach on the day the complaint is filed, on the day the defendant answers, or on some other event, and does it apply to the whole recovery or only to the amount above what was offered pre-suit?
Fees and costs are different animals. The fee is the firm's compensation. Costs are money the firm advances on the client's behalf: filing fees, service of process, court reporters and transcripts, medical record retrieval, accident reconstruction, expert reports, mediator time, exhibits. In an ordinary pre-suit claim they may run to a few hundred dollars. In a filed case with two or three retained experts they can reach five figures without anyone doing anything unusual. Two questions decide how much this costs the client. First, is the fee calculated on the gross recovery or on the recovery after costs are deducted, because the gross method is standard but produces a smaller net. Second, does the client owe advanced costs if the case is lost, and if the agreement says so, whether the firm waives that in practice.
What is left after fees and costs is not yet the client's money. Anyone who treated the injury on credit, or who paid for treatment and has a right to be repaid out of a recovery, sits ahead of the client in line. That includes hospital liens filed under state statute, letters of protection signed with a treating orthopedist or a surgery center, and health insurer reimbursement claims. The last category is where the rules get technical. A self-funded employer plan governed by ERISA, a Medicare conditional payment, and a Medicaid claim each operate under different authority and reduce on different terms. The Centers for Medicare and Medicaid Services oversees the federal conditional payment process, and clearing it is a normal step that a firm handling injury work does routinely, though it takes time.
Liens are quoted at full billed charges, and billed charges are rarely what anyone actually expects to collect. Provider balances get negotiated down, sometimes substantially, particularly when the settlement is limited by an insurance policy and everyone in line has to accept less. Some states apply a common fund doctrine that requires a subrogated insurer to bear a proportional share of the attorney's fees and costs incurred to create the recovery, which reduces the reimbursement without anyone asking. A careful reader asks, before signing anything, who negotiates the liens, whether that work is included in the contingency fee or billed on top, and whether the final statement will show both the original balance and the reduced figure side by side.
The disbursement sheet should reconcile without arithmetic on the reader's part, and it usually does. Look for the gross settlement, the fee with its percentage and the tier it was drawn from, an itemized cost list rather than a single lump labeled expenses, each lienholder by name with the amount claimed and the amount paid, and the net to the client. If a number is a placeholder because a Medicare demand has not come back yet, the statement should say so and hold that amount in trust rather than guess. Ask for the itemization before the check is deposited, compare the fee percentage against the agreement signed at intake, and settle any discrepancy while the file is still open and the ledger still easy to pull.
None of this changes whether hiring someone was worth it, which depends on what the claim was worth in the first place and what a firm's work added to it. It changes whether the client understands the check when it arrives, and understanding it is mostly a matter of asking two or three unglamorous questions at the beginning and reading four lines carefully at the end.
A fee taken on the gross recovery before costs yields the client less than a fee taken after costs are deducted. The agreement will say which method applies, usually in a single sentence.
