My Client Hasn't Paid My Invoice in 60 Days — What Can I Do as a California Freelancer?

California freelancer with an unpaid invoice? Here's exactly what to do when a client goes silent or keeps stalling after 60 days.

Sixty days have passed. You've sent reminders. You've followed up by email. And now the client either ignores you or keeps saying "the check is in the mail." If this sounds familiar, you're not stuck — and you don't need to hire a lawyer on retainer to do something about it.

Short answer: Start with a formal demand letter. In California, a written demand for payment — especially one on attorney letterhead — resolves most unpaid invoice disputes without ever stepping into court. It signals that you're serious, creates a paper trail, and often prompts payment within days.

Why the First 60 Days Matter

After 30 days, an unpaid invoice is overdue. After 60 days, it's a problem. After 90, it becomes genuinely hard to collect without escalation. California's statute of limitations for written contracts is four years (Code of Civil Procedure § 337), so the legal clock is long — but the practical window for easy collection is much shorter.

Clients who ignore invoices often do so because they don't believe you'll take action. The moment they see that you're willing to escalate, most will pay or at least negotiate. A formal demand letter is the first step that changes the dynamic.

Step 1: Send a Formal Written Demand

A demand letter is a formal written notice that you are owed money and will take legal action if the debt isn't paid by a specific deadline. It's not a lawsuit — it's a warning that a lawsuit is possible.

An effective demand letter for an unpaid invoice should include:

The letter doesn't need to be aggressive, but it does need to be specific and come on legitimate letterhead. An attorney-signed letter carries significantly more weight than an email from your personal account.

Step 2: Know What California Law Says About Freelancer Pay

California has some of the strongest protections for independent contractors in the country. Under general contract law, once you've delivered the work and the client accepted it, they owe you the agreed fee — full stop.

If you had a written contract, enforcing it is straightforward: you performed, they didn't pay, you can demand the amount owed plus interest (typically 10% annually under California law for commercial debts). If you worked on a handshake deal, you still have rights — oral contracts for services are enforceable in California small claims court.

Step 3: Give a Real Deadline

Vague emails don't move the needle. "Please pay when you get a chance" gives the client an easy out. A demand letter with a specific deadline — "You have until May 28, 2026 to submit full payment of $4,750" — removes ambiguity and creates urgency.

If they miss the deadline, you've documented that the non-payment was deliberate, which strengthens any future legal claim.

Step 4: Be Ready to Escalate — But You May Not Need To

If the demand letter works (and it does in most cases), you're done. If it doesn't, California small claims court handles disputes up to $12,500 for individuals, and the filing fee is under $100. The process is designed for non-lawyers. You show up, present your invoice, your contract, and your demand letter — and the judge typically rules the same day.

For amounts above $12,500, you'd file in limited civil court, where having an attorney-drafted demand letter becomes even more valuable as prior-litigation documentation.

When a letter is the right tool: if you've already sent informal reminders and the client is ignoring them, a formal attorney-drafted demand letter is the fastest path to payment before you consider going to court.
