Being served with a collection lawsuit is stressful, and the most common response — setting the papers aside and hoping it goes away — is the single most expensive mistake you can make. Collectors count on defaults. Roughly speaking, the collector's business model works because most people never respond. Here is what actually happens if you default, and what to do instead in the first 30 days.
What a default judgment costs you
In California, you generally have 30 days after service of the summons and complaint to file a written response with the court. Miss that window and the collector can request entry of your default, then a default judgment — a court determination, without your defenses being heard, that you owe the amount the court awards. Once judgment enters, the collector can:
- Garnish your wages through an earnings withholding order
- Levy your bank accounts
- Record a lien against your real property
- Add post-judgment interest, generally at 5% or 7.5% per year for personal-debt judgments entered or renewed on or after January 1, 2023, and 10% for other judgments, plus costs
Most judgments remain enforceable for 10 years and may be renewed, although California restricts renewal of certain smaller judgments arising from personal debt or medical expenses. Defaulting converts a contestable claim into a decade of collection exposure. Whatever the merits of the underlying debt, responding is almost always cheaper than defaulting.
First: figure out who is suing you and for what
Read the complaint carefully. Is the plaintiff the original creditor, or a debt buyer you have never heard of with a name like a hedge fund? This matters. Debt buyers must satisfy California's Fair Debt Buying Practices Act, Civil Code § 1788.50 et seq., which requires them to plead and prove specific facts — including the chain of title showing they actually own your account, the balance at charge-off, and an itemization of post-charge-off interest and fees (see Civ. Code § 1788.58). Many purchased-debt files cannot meet that standard when pressed.
Also check the math. Complaints frequently demand balances swollen by interest and fees the plaintiff cannot substantiate, and sometimes name the wrong person entirely.
Second: check the statute of limitations
California allows four years to sue on a written contract (CCP § 337) and two years on an oral agreement (CCP § 339), generally measured from your default. If the suit was filed too late, the statute of limitations is a complete defense — but it is an affirmative defense, meaning you must raise it in your response or you lose it. California law goes further for purchased consumer debts: a debt buyer may not bring suit on a time-barred debt at all (Civ. Code § 1788.56), and doing so can expose the buyer to liability. This is exactly the kind of defense that a default silently waives.
Third: respond — you have real options
Within the 30-day window, you can typically:
- File an answer. This denies the allegations you dispute and asserts your affirmative defenses — limitations, payment, identity error, lack of standing, improper amounts. Filing an answer forces the collector to prove its case with admissible evidence, which many cannot do economically.
- Challenge the pleadings. If the complaint is legally defective — for a debt buyer, missing the facts § 1788.58 requires — a demurrer can attack it before you ever answer.
- Negotiate from a position of strength. A defendant who has appeared and asserted defenses negotiates a very different settlement than one facing default. Lump-sum settlements at a substantial discount, dismissals in exchange for payment plans, and agreements with credit reporting terms all become realistic.
Deadlines and formatting rules are strict, and a defective response can be as bad as none. This is where experienced debt validation counsel earns its keep — evaluating whether the plaintiff can prove ownership and amount, and choosing the response that fits your facts.
Watch for violations that turn defense into offense
Collection lawsuits are sometimes accompanied by conduct that violates the Fair Debt Collection Practices Act, 15 U.S.C. § 1692 et seq., or California's Rosenthal Act, Civil Code § 1788 et seq. — suing on time-barred debt, misstating the amount owed, threatening action the collector cannot take, or continuing collection without providing verification after a timely written dispute. These violations support claims for actual damages, statutory damages, and attorney fees, and they can become counterclaims or settlement leverage inside the collector's own lawsuit.
If you already defaulted
All is not necessarily lost. California courts can set aside defaults on grounds such as mistake, inadvertence, or excusable neglect (CCP § 473), and improper service can support relief even later. But these motions have their own tight deadlines and are far harder than simply responding on time. If a default or default judgment has been entered against you, act immediately.
