How Much Does Business Litigation Cost? A Complete Guide to Legal Fees and Expenses in Washington State

One of the first questions business owners ask when facing a lawsuit — whether as plaintiff or defendant — is simple: what will this cost? Unfortunately, the answer is rarely simple. Business litigation costs in Washington State depend on the complexity of the case, the court in which it’s filed, how aggressively the opposing side litigates, and how far the case proceeds before resolution. Understanding the components of litigation expense, and the Washington-specific rules that affect who pays what, helps businesses budget realistically and make informed decisions about whether to fight, settle, or avoid a dispute altogether.

This guide breaks down the major cost categories in Washington commercial litigation and offers practical strategies for controlling expenses.

Attorney Fees: The Largest Cost Driver

For most businesses, attorney fees represent the single largest litigation expense. In Washington, commercial litigation attorneys typically bill in one of several ways:

• Hourly billing is the most common arrangement for business litigation. Rates vary by market and experience level, with attorneys in Seattle and the greater Puget Sound region generally charging more than attorneys in smaller Washington markets. Partner-level commercial litigators at established firms often bill well into the hundreds of dollars per hour, while associates and paralegals bill at lower rates.
• Flat fees are sometimes used for discrete tasks, such as drafting and filing a specific motion, but are less common for full-case representation given the unpredictable nature of litigation.
• Contingency fees, where the attorney takes a percentage of any recovery instead of hourly billing, are more common in plaintiff-side cases involving fraud, breach of fiduciary duty, or other claims with strong damages potential, but are rare in pure defense work.
• Hybrid arrangements, blending a reduced hourly rate with a contingency component, are increasingly used in larger commercial disputes to align incentives between the business and its counsel.

Under the “American Rule,” which Washington follows as a default, each party generally pays its own attorney fees regardless of who wins — unless a statute, contract, or recognized equitable ground provides otherwise. This makes Washington’s exceptions to the American Rule especially important to understand, since they can shift significant costs onto the losing party.

Statutory and Contractual Fee-Shifting in Washington

Washington law recognizes several important exceptions where the prevailing party can recover attorney fees:

• Contractual fee provisions. Many commercial contracts include a clause awarding attorney fees to the prevailing party in any dispute arising from the agreement. Washington courts enforce these provisions, and under RCW 4.84.330, a unilateral attorney fee clause (one that only allows one party to recover fees) is treated as bilateral — meaning either party can invoke it if they prevail, regardless of how it was originally drafted.
• The Washington Consumer Protection Act. RCW 19.86.090 allows a prevailing plaintiff to recover reasonable attorney fees and costs, which is one reason CPA claims are frequently pursued in Washington business disputes.
• Other statutory claims, including certain wage claims, franchise disputes, and specific consumer protection statutes, may also carry fee-shifting provisions.

Because fee-shifting can dramatically change the cost calculus of a lawsuit, reviewing the underlying contract and applicable statutes early in a dispute is a critical step in estimating true litigation exposure.

Court Filing Fees and Administrative Costs

Compared to attorney fees, court costs are relatively modest but still add up over the life of a case. In Washington Superior Court, filing a civil lawsuit requires payment of a statutory filing fee, and additional fees apply for actions such as filing a jury demand, requesting a case be set for trial, or filing certain motions. County clerks set some fees within statutory limits, so costs can vary modestly from county to county.

Businesses should also budget for:

• Service of process fees for delivering the summons and complaint to the defendant
• Fees for obtaining certified copies of court records
• Costs associated with filing exhibits or transcripts
• Jury fees, if the case proceeds to a jury trial

While these costs are far smaller than attorney fees, they are a real and recurring expense throughout litigation.

Discovery Costs

Discovery — the process of exchanging evidence between parties — is often where litigation costs escalate quickly, particularly in commercial disputes involving large volumes of documents, financial records, or electronically stored information (ESI).

Under Washington’s Superior Court Civil Rules, parties can propound interrogatories, requests for production, requests for admission, and take depositions. Each of these carries cost:

• Document review and production often requires significant attorney and paralegal time, especially when a business must review thousands of emails or files for relevance and privilege before producing them.
• E-discovery vendors are frequently retained in larger commercial cases to process, host, and search electronic data, and their fees can range from a few thousand dollars for smaller matters to well into six figures for data-intensive disputes.
• Depositions require court reporter fees, transcript costs, and often significant attorney preparation time. A single day of deposition, once attorney time and transcript costs are included, can be one of the more expensive single events in a case.

Discovery disputes — where one side believes the other is withholding relevant information — can also generate additional costs through motions to compel, and Washington courts have authority under CR 37 to award the reasonable expenses, including attorney fees, incurred in bringing or defending a successful discovery motion.

Expert Witness Costs

Many commercial disputes hinge on issues requiring specialized expertise, such as lost profits calculations, industry standards, accounting irregularities, or valuation disputes. Expert witnesses in Washington commercial cases typically charge for:

• Reviewing case materials and forming opinions
• Preparing a written expert report (required for testifying experts under Washington’s disclosure rules)
• Deposition testimony
• Trial testimony, often billed at a premium hourly or daily rate

Depending on the complexity of the financial issues involved, expert costs in a mid-sized commercial case can range from several thousand dollars to well over $50,000, particularly if multiple experts are needed on both liability and damages issues.

Settlement Costs and the Value of Early Resolution

Settling a case is not free — settlements themselves may involve negotiated payments, but the broader point is that settlement, especially early settlement, is almost always less expensive than protracted litigation. The longer a case proceeds, the more attorney hours, discovery expenses, and expert fees accumulate.

Washington courts and county programs often encourage early mediation for this reason. Mediator fees are typically split between the parties and are a fraction of the cost of continued litigation. For business disputes below a certain dollar threshold, many Washington counties, including King County, require mandatory arbitration under the county’s Mandatory Arbitration Rules (MAR) before a case can proceed to trial — a process generally faster and less expensive than full civil litigation, though a dissatisfied party can request a trial de novo, which carries its own cost risk if the appealing party doesn’t improve its position.

How Businesses Can Control Litigation Costs

While litigation is inherently unpredictable, Washington businesses can take concrete steps to manage expenses:

1. Conduct an early case assessment. Understanding the strengths, weaknesses, and likely value of a claim before investing heavily in litigation helps avoid throwing good money after a weak case.
2. Negotiate fee arrangements with counsel. Discussing budget expectations, alternative fee structures, or capped-fee arrangements for discrete phases of litigation can create more predictable costs.
3. Scope discovery carefully. Working with counsel to narrow discovery requests and responses to what’s genuinely relevant limits unnecessary document review and vendor costs.
4. Use mediation and arbitration where appropriate. Resolving disputes outside of full trial litigation, when contractually or strategically available, often produces significant savings.
5. Review contracts for fee-shifting language before disputes arise. Businesses that negotiate favorable attorney fee provisions in their contracts on the front end may recover costs if a dispute later arises and they prevail.
6. Preserve evidence early. Avoiding spoliation issues and last-minute scrambles to locate documents reduces costly discovery disputes and potential sanctions under Washington’s evidentiary rules.

Conclusion

Business litigation costs in Washington State vary enormously based on the nature of the dispute, the amount in controversy, and how the case is litigated. Attorney fees typically dominate the budget, but discovery, expert witnesses, and court costs all contribute meaningfully to the total expense. Washington’s fee-shifting statutes — particularly under the Consumer Protection Act and RCW 4.84.330’s treatment of contractual fee clauses — can significantly change the cost-benefit calculation for both plaintiffs and defendants. Businesses that engage counsel early, assess their case realistically, and remain open to mediation or arbitration are generally best positioned to control costs while still protecting their legal interests.
