Contingency Fee Billing: A Solo Attorney's Complete Guide
Contingency fee arrangements are a cornerstone of plaintiff-side litigation. You don't get paid unless your client wins — which means you're betting your time on the outcome. For solo attorneys, this creates both opportunity (access to higher-value cases) and risk (months of unpaid work if the case doesn't settle).
Here's how to structure, track, and manage contingency cases effectively.
How contingency fees work
The basics:
- You receive a percentage of the recovery — typically 33-40% of the settlement or judgment
- The client pays no upfront legal fees — but usually remains responsible for costs (filing fees, expert witnesses, depositions)
- If you lose, you earn nothing — your time investment is at risk
Standard contingency fee structures
| Stage | Typical fee |
|---|---|
| Pre-litigation settlement | 25-33% |
| After filing suit | 33% |
| After discovery / close to trial | 40% |
| On appeal | 40-45% |
Many attorneys use a sliding scale that increases as the case progresses, reflecting the additional work required.
When contingency fees make sense for solos
Good contingency cases:
- Personal injury with clear liability and significant damages
- Employment discrimination with documented evidence
- Consumer protection / fraud cases with statutory fee provisions
- Medical malpractice (higher risk, but higher potential recovery)
Cases to avoid on contingency:
- Unclear liability or "he said / she said" situations
- Low-damage cases (a 33% fee on a $10,000 recovery is $3,300 — likely below your hourly rate for the work required)
- Cases requiring expensive expert witnesses you can't afford to front
The contingency fee agreement
Every contingency arrangement needs a written fee agreement. Essential terms:
- Fee percentage — and whether it's calculated before or after costs are deducted
- What counts as "recovery" — settlements, judgments, awards, statutory fees
- Cost responsibility — who pays litigation costs, and when
- Withdrawal provisions — what happens if you withdraw or the client fires you
- Fee disputes — arbitration clause per your state bar rules
Before costs vs. after costs — it matters
| Calculation method | Settlement: $100,000 | Costs: $10,000 |
|---|---|---|
| Fee on gross (before costs) | $33,000 fee → client gets $57,000 | |
| Fee on net (after costs) | $29,700 fee → client gets $60,300 |
Most plaintiff attorneys calculate fees on gross recovery. Be transparent about this in your fee agreement — it's a common source of client confusion.
Tracking time on contingency cases
"But I'm not billing hourly — why track time?"
Three important reasons:
1. Fee reasonableness challenges
Courts can reduce contingency fees that are deemed unreasonable. Having detailed time records proves the work you invested and supports your fee if challenged.
2. Statutory fee petitions
In cases with fee-shifting provisions (civil rights, consumer protection), you may petition for attorney's fees based on hourly rates — even in contingency cases. You need time records for this.
3. Business intelligence
Without tracking time, you have no idea which contingency cases are profitable. A $100,000 settlement at 33% sounds great — until you realize you spent 400 hours on it, making your effective rate $82.50/hour.
Managing cash flow with contingency cases
The biggest challenge for solo attorneys taking contingency cases: you need to eat while waiting for settlements.
Strategies:
- Mix hourly and contingency work — don't go 100% contingency unless you have 6+ months of reserves
- Advance costs carefully — set a budget for each case and track costs against it
- Review case economics quarterly — if a case is consuming too many hours relative to likely recovery, reassess
- Consider co-counsel — sharing a large case with another attorney reduces both risk and workload
