Frequently Asked Questions

Yes. While a signed contract strengthens your position, California recognizes implied contracts and quantum meruit claims. If you can prove the client requested your services, you performed them, and the client accepted the benefit, you have a valid claim even without a written agreement. Your demand letter should cite California Civil Code §1621 (implied contracts) and include copies of emails or messages showing the client's request for your work and agreement to your rates.

This is the best position to be in from a legal standpoint. Their continued use of your work contradicts their claim that it's defective. In your demand letter, point out this inconsistency explicitly: "You claim my logo design was 'not what you ordered,' yet you continue to display it prominently on your website, business cards, and social media. Your actions demonstrate acceptance of my work." Courts view continued use as strong evidence of acceptance. If they're truly using defective work, they'd stop using it.

Under 17 U.S.C. §201(a), copyright vests in the author at the moment of creation. For independent contractors (not employees), you automatically own the copyright unless you signed a work-for-hire agreement or explicit copyright assignment. The burden is on them to prove they own it, not on you to prove you do. In your demand letter, state: "As the author of this work and an independent contractor (not an employee), I retain copyright ownership under 17 U.S.C. §201(a). Your contract contains no work-for-hire provision or copyright assignment. Your unauthorized use constitutes infringement." Save your original work files with creation dates as evidence if needed later.

Yes, if your contract includes an interest provision OR if you're pursuing a breach of contract claim in California. Under California Civil Code §3289(b), you can recover 10% annual interest on unpaid contract amounts from the date payment was due. Calculate it as: (Principal × 0.10 × Days Overdue) / 365. So a $5,000 invoice that's 60 days overdue accrues about $82 in interest. For invoices over 180 days overdue, this adds up to meaningful amounts. Always include accrued interest in your demand letter total.

For demand letters I personally draft, I see full payment in about 65-70% of cases within 30 days. Partial settlement (50-80% of the amount owed) happens in another 15-20% of cases. About 10-15% require follow-up litigation or result in no recovery. The key variables are documentation quality (signed contract vs. oral agreement), amount owed (higher amounts get more resistance), and whether the client is still using the work (copyright leverage dramatically improves odds). DIY demand letters written by freelancers themselves succeed in about 45-50% of cases in my experience.
