Suing Over an Unpaid Debt in California: Process and Cost

Suing over an unpaid debt is a business decision before it is a legal one: what will it cost, how long will it take, and will the judgment actually turn into money? California's process is more predictable than most litigation — many debt cases end in default or early settlement — but the economics deserve a clear-eyed look first. Here is the process from complaint to collection, with real numbers.

Before filing: three questions that decide everything

  1. Is the claim timely? Written contracts carry a four-year limitations period (CCP § 337); oral agreements only two years (CCP § 339); open book accounts four years (CCP § 337(2)). A signed written acknowledgment or promise can restart the clock (CCP § 360).
  2. Can the debtor pay? A judgment against a defunct LLC or a debtor headed to bankruptcy is expensive paper. Basic asset research — property records, UCC filings, business status, banking relationships — comes before the filing fee.
  3. Who bears the legal fees? California follows the American rule: each side pays its own attorneys unless a statute or contract says otherwise. If your contract has an attorney-fee clause, Civil Code § 1717 generally makes it reciprocal in an action on the contract and changes the math entirely — the prevailing party may recover reasonable fees.

The costs, itemized

  • Filing fees: roughly $30–$75 in small claims; $225–$385 for a limited civil complaint, depending on the amount and county; $435–$450 for an unlimited civil complaint. Service of process typically adds $50–$150 per defendant.
  • Attorney's fees: vary with the debtor's resistance. An uncontested case that ends in default judgment costs a fraction of one that goes through discovery. Fee structures for collection work include hourly, flat-fee stages, and contingency arrangements, and the right fit depends on the size and strength of the claim.
  • Recoverable amounts: the winning creditor generally recovers court costs, prejudgment interest at 10% per year on contract debts with no stated rate (Civil Code § 3289(b)), and — with a fee clause — attorney's fees. Post-judgment interest generally accrues at 10% annually, although a 5% rate applies to qualifying judgments under $200,000 involving medical expenses or personal debt (CCP § 685.010).

The lawsuit, stage by stage

Complaint and service (weeks 1–8). The complaint pleads the debt under theories that reinforce each other — breach of contract, open book account, account stated, and any guaranty. The debtor must be served, and then has 30 days to respond.

Default — how many debt cases end (months 2–4). If the debtor files nothing, the clerk enters default, cutting off the right to respond, and the court can enter judgment for the amount proven. Debt cases produce defaults at a far higher rate than other civil litigation, which is why a well-documented claim often costs less to prosecute than creditors fear.

Contested track (months 3–18). If the debtor answers, the case proceeds through discovery. Requests for admission are especially potent in debt cases — asking the debtor to admit the invoices are genuine and unpaid narrows the trial to almost nothing, and unjustified denials can support cost awards. Many contested collection cases resolve at mediation or on a motion for summary judgment once the documents are established.

Judgment. Whether by default, motion, or trial, the case ends in a judgment — valid for ten years and renewable (CCP § 683.020).

Two tools that change the leverage

Writ of attachment. In commercial cases, CCP § 483.010 allows a creditor suing on a contract claim of a fixed or readily ascertainable amount of at least $500 to seek a prejudgment attachment of eligible assets while the case proceeds. Granted early, it can preserve assets for recovery and frequently produces settlement, because the debtor loses the ability to outlast you with your own money.

Stipulated judgment settlements. Debtors who want a payment plan can sign a settlement that permits entry of a stipulated judgment upon default without a new lawsuit. The terms must be carefully structured so that the judgment amount is enforceable and does not constitute an unlawful penalty.

Collecting after judgment

Judgment enforcement is its own phase, and planning it from day one is what separates recoveries from wall decorations. The toolkit includes bank levies via writ of execution, wage garnishment against individual debtors, recorded judgment liens on real estate, liens on business assets, court-ordered debtor examinations under oath, and for cash businesses, sheriff keeper levies. Interest at the applicable statutory rate keeps accruing throughout. If the debtor transferred assets to avoid the debt, the Uniform Voidable Transactions Act allows those transfers to be unwound. A systematic approach to all of this is the core of our debt collection practice, and for disputed debts that turn into genuine litigation, our business litigation experience covers the contested track.
