Line of Credit for Law Firms in 2026: Fund Case Costs, Smooth Settlement Timing & Cover Payroll

A business line of credit gives a law firm a standing pool of capital — typically $25K–$500K at 8–22% APR — that the firm draws when case costs or payroll come due and repays when settlements and receivables land, paying interest only on the drawn balance. For contingency-fee practices in particular, no other financing structure matches the shape of the cash flow.

The structural problem is case costs. A personal injury or mass-tort firm fronts every dollar of litigation expense — expert witnesses at $5,000–$50,000 per case, deposition transcripts at $500–$1,500 each, filing fees, medical record retrieval, accident reconstruction, trial exhibits — and recovers none of it until the case resolves. On a typical contingency timeline that's 12–36 months of capital locked in the case file. A mid-sized PI firm carrying 150 active cases at an average $8K–$15K in advanced costs has $1.2M–$2.25M of its own cash sitting in case inventory at any given moment, generating zero interest and unavailable for payroll.

Hourly and flat-fee firms face a milder version of the same math. Corporate clients routinely pay on net-60 to net-90 terms, and realization rates mean a firm billing $300K in a month may collect $220K–$255K of it — sixty to ninety days later. Meanwhile associate salaries, paralegal payroll, malpractice premiums, and rent run on a fixed calendar. A revolving business line of credit converts that timing mismatch from a recurring crisis into a routine draw-and-repay cycle.

The Contingency-Fee Cash Flow Cliff

Contingency revenue is lumpy by design: a firm might close $900K in fees across three settlements in March, then collect almost nothing in April and May while the next tranche of cases works through discovery. Fixed overhead doesn't pause. A firm with $150K/month in operating costs and a two-month settlement gap needs $300K of bridge liquidity — exactly the situation a revolver is built for, and exactly the situation where a lump-sum term loan forces you to borrow (and pay interest on) money months before you need it.

Case Costs Are an Investment With a Long Payback

Every case a contingency firm accepts is effectively a capital allocation decision. Turning down a strong case because the firm can't front $40K in expert and deposition costs is turning down a fee that might be $200K+. Firms that maintain committed credit capacity can take the cases their pipeline deserves rather than the cases their checking account allows.

A law firm line of credit is approved once and then sits available, usually for a 12–24 month renewable term. The firm draws any amount up to the limit — $12K for a round of depositions, $60K for payroll during a settlement gap — via same-day or next-day transfer to the operating account. Interest accrues only on the outstanding balance, not the full limit. Draw $50K against a $250K line at 14% APR, repay it 90 days later when a settlement funds, and the interest cost is roughly $1,750 — the unused $200K cost nothing.

That interest-only-on-drawn-balance mechanic is why a revolver beats a lump sum for irregular settlement timing. A $250K term loan starts the amortization clock on the full amount at closing, whether the firm needs the money that month or not. A $250K line costs nothing in months where nothing is drawn. For a firm whose funding need spikes around trial calendars and settlement gaps, the revolver's effective cost is a fraction of an equivalent term facility.

Repayment on draws is typically weekly or monthly, and most firms run the line as a cycle: draw against case costs and payroll, sweep settlement proceeds against the balance, restore full availability, repeat. As the balance is repaid, capacity replenishes automatically — no reapplication. See how a revolving credit line works for your firm, or start with a soft-pull application to see real numbers.

What a Draw Cycle Looks Like in Practice

A three-partner PI firm with a $200K line: draws $35K in February for experts and filing fees on two new trucking cases, draws $45K in March to cover payroll while a mediation drags, settles a case in April and sweeps $80K back against the line. Total interest paid for the quarter at 12% APR: roughly $1,900. The alternative — leaving $200K of partner capital idle in the operating account year-round to self-insure the same gap — costs far more in foregone distributions.

Three provider categories issue lines of credit to law firms, and they trade off rate against speed and flexibility:

Option	APR	Time to open	Typical fit
Bank line of credit	8–14%	30–60 days	Established firms, 650+ FICO, 2+ years, strong financials; cheapest capital but slowest and most document-heavy
Online line of credit	12–22%	1–7 days	Firms that need capacity fast, 600+ FICO, 1+ year in business; underwritten primarily on bank deposits
SBA CAPLine	9–11.5%	45–75 days	Firms with 680+ FICO and 2+ years wanting larger working-capital lines with government-backed pricing

Banks like lending to law firms on paper — professional-services borrowers with licensed principals — but many bank credit teams struggle with contingency-fee income statements, where revenue recognition is lumpy and WIP doesn't appear as a conventional receivable. Firms with heavy contingency mix often get better outcomes from online lenders and specialist credit programs that underwrite on 3–4 months of actual bank deposits rather than GAAP revenue.

Bay Street Lending brokers across 50+ lenders and funding partners — banks, online lenders, and SBA — from one soft-pull application with no upfront fees, so a firm sees its real options across all three categories rather than the one category it happened to walk into. First offers on clean files typically come back in under 4 hours. Compare law firm credit line offers across 50+ lenders.

Law firm underwriting has three quirks that generalist borrowers never encounter, and getting ahead of them speeds approval and improves offer size:

• Trust vs. operating account discipline. IOLTA and client trust deposits are client money, not firm revenue — no underwriter will count them, and a firm that commingles or submits trust statements as evidence of deposits raises immediate red flags. Submit operating account statements only, and make sure fee transfers from trust to operating are clean and regular. A firm whose earned fees move promptly from trust to operating shows a stronger, more legible deposit pattern.
• WIP and case inventory. For contingency firms, the real asset is the case docket — signed cases, expected fee values, and historical resolution rates. Bank statements carry the underwriting, but a simple case inventory summary (count, practice mix, average fee, average time to resolution) gives underwriters context for lumpy deposits and frequently increases the approved limit.
• Partner compensation normalization. Small-firm P&Ls often show thin profit because partners sweep earnings out as draws and distributions. Underwriters familiar with professional services add those back — but only if they can see them. Flagging $400K of partner distributions on an otherwise break-even P&L is the difference between looking marginal and looking strongly profitable.

Beyond those, the standard inputs apply: 3–4 months of operating bank statements, $15K+/month in deposits, 1+ year in business (2+ for bank and CAPLine options), and FICO 600+ for online lines or 650+ for bank lines. Firms carrying an existing case-cost funding facility should disclose it upfront — stacked facilities that surface late in underwriting stall approvals.

A Practical Note on Ethics and What the Line Funds

Financing firm operations — payroll, rent, marketing, technology — is uncontroversial in every jurisdiction. Advancing client litigation costs is also broadly permitted, but state bar rules vary on how those advances are structured and recouped, and interest pass-through to clients is regulated differently state to state. The clean pattern most firms use: the line funds the firm; the firm advances costs to cases under its normal engagement terms. This is practical context, not legal advice — confirm treatment with your state bar or ethics counsel.

Line limits scale with deposit volume and, for contingency firms, the size and quality of the case inventory. Rough bands across our funded deals:

• Solo practitioner or 2-attorney firm ($25K–$80K/mo deposits): $25K–$75K line. Common uses: fronting deposition and expert costs on 5–15 active contingency cases, bridging a slow collections month, covering the malpractice premium when it lands in one invoice.
• Small firm, 3–8 attorneys ($80K–$250K/mo deposits): $75K–$250K line. Typical uses: payroll continuity through settlement gaps, case-cost pools for a growing PI docket, intake marketing that has to be paid months before signed cases resolve.
• Mid-sized firm, 9–25 attorneys ($250K–$600K/mo deposits): $200K–$500K line. Often used as a firm-wide case-cost facility, a bridge across contingency revenue cycles, or working capital during a lateral group hire when payroll rises before the book of business converts.

For a deeper walkthrough of limits, pricing mechanics, and how funders set line sizes across industries, see our complete business line of credit guide. The law-firm-specific rule of thumb: firms with clean trust/operating separation and 12+ months of deposit history routinely qualify at the top of their deposit band, while firms with erratic transfers between accounts get sized conservatively regardless of revenue.

A revolver is the right structure for recurring, unpredictable draws. But two situations favor a revenue-based working capital advance instead — and firms should pick the tool by the shape of the need, not by habit.

One-time, immediate, defined need. A firm that needs $100K this week — a mass-tort cost commitment, a trial about to start, a quarter of payroll during a stuck settlement — is better served by an advance that funds in 6–24 hours than by a bank line that opens in 30–60 days. A working capital advance delivers $25K–$2M sized at roughly one month of average deposits, with a fixed total payback quoted after review, repaid through a small fixed weekly (or in some cases daily) debit over 3–18 months. There's no facility to maintain afterward; it's a bridge, used once.

Credit below the line-of-credit thresholds. Online lines generally want 600+ FICO and bank lines 650+. Working capital advances are credit-flexible — principals with scores in the 500s qualify when the firm shows 6+ months in business and $15K+/month in consistent operating deposits, because the underwriting weight sits on cash flow, not the credit file. For the full law-firm treatment of that product, see our guide to working capital for law firms.

Many firms end up running both: a standing law firm credit line for routine case-cost and payroll cycling, plus an advance when a large one-time need outruns the line's limit or timeline. Bay Street places both requests across 50+ lending partners from one application, so the comparison is made with real offers on the table rather than in the abstract.

Documents to Have Ready

1. Last 3–4 months of operating account bank statements (not IOLTA/trust — all pages, PDF or bank connection)
2. Driver's license for any 20%+ partner
3. Voided business check for funding setup
4. Optional but valuable: case inventory or AR aging summary — one page of docket context routinely improves offers for contingency-heavy firms

One application, one soft credit pull, offers from banks, online lenders, and SBA programs side by side — typically under 4 hours to first numbers on a clean file.
