How to write a demand letter in Contra Costa County
Updated August 2026 · Code of Civil Procedure § 116.320
Do I need to send a demand letter before filing small claims in Contra Costa County?
Usually yes. In California small claims, you generally must ask for payment or return of property before you file, and that requirement comes from Code of Civil Procedure § 116.320. A clear written demand letter is the simplest way to prove you asked.
If you are in Concord, Richmond, Antioch, Walnut Creek, Pittsburg, Martinez, San Ramon, Brentwood, or elsewhere in the county, the basic rule is the same: ask first, then file if needed. That matters because Contra Costa small claims cases are heard in Martinez, Pittsburg, and Richmond, so if your dispute ends up in court, the judge may want to know whether you tried to resolve it before making the trip to one of those courthouses.
A demand letter also helps even when the other side ignores you. It creates a clean timeline, shows what you wanted, and reduces the chance of a fight later about whether you ever asked.
What should a demand letter say?
Keep it short, specific, and calm. Say who you are, what happened, what you want, and what you will do next if the problem is not fixed.
You do not need legal language. In most cases, your letter should sound like a serious business note, not a threat. The goal is to make it easy for the other person to understand the problem and choose to solve it.
- Your full name and the best way to contact you.
- The other person's or business's correct name.
- A simple timeline of what happened, with dates if you know them.
- What you paid, what was promised, or what property is involved.
- What you want now: payment, repair, return of a deposit, return of property, or something else.
- A clear statement that if the matter is not resolved, you may file in small claims court.
- Copies of key proof, like a contract, invoice, text message, photos, or receipts.
A simple fill-in structure
- State the relationship: "I hired you for..." or "You owe me for..."
- Explain the problem in a few sentences: what was agreed, what went wrong, and when.
- State the fix you want: "Please pay..." or "Please return..."
- Say how they can resolve it and where to send payment or property.
- Say that if it is not resolved, you may file a small claims case in Contra Costa County.
What is a good demand letter example for a Contra Costa County case?
A good letter is direct and factual. It avoids insults, long arguments, and legal buzzwords that make people defensive.
You can adapt this wording:
"I am writing to demand payment for [describe the debt or loss]. On [date], we agreed that [describe the agreement]. I performed my part by [what you did], but you did not [what they failed to do]. As a result, I lost [money, property, time, or other specific harm]. Please resolve this by [paying the amount owed / returning the property / completing the agreed repair]. If I do not hear from you, I may file a claim in Contra Costa County small claims court."
If the dispute involves a written contract, keep a copy with your letter and records because written-agreement claims generally have a time limit of 4 years. If the agreement was only spoken, the general time limit is shorter, usually 2 years.
How much detail should I include?
Include enough detail to make the claim understandable, but not every grievance you have ever had. Most strong demand letters fit on one page or a little more.
Focus on facts that matter to payment or repair: the agreement, the breach, and your loss. If you bury the key point in a long emotional story, the other side may miss the actual demand.
- Good detail: dates, receipts, messages, photos, invoice numbers, and the exact work or item involved.
- Less helpful detail: insults, guesses about motives, or long side disputes that do not affect what is owed.
- Best tone: firm, respectful, and ready to show a judge if needed.
How should I send the demand letter in Contra Costa County?
Send it in a way you can later prove. Mail is common, and email or text can help if that is how you normally communicate, but keep copies of everything.
Proof matters because if the dispute ends up at one of the Contra Costa hearing locations in Martinez, Pittsburg, and Richmond, you may want to show the judge that you tried to solve it first. Keep the final letter, any attachments, proof of mailing, delivery confirmation if you have it, and screenshots of any replies.
If you are dealing with a business, send the letter to the business name and also to the person or department you actually dealt with if you know it. If the other side moves around or ignores calls, sending the letter to the best known address is usually better than doing nothing.
What happens if they ignore my demand letter?
You still gained something: a clear record. If they do not respond or refuse to fix the problem, you can decide whether to negotiate more, try mediation, file small claims, or walk away.
| Your option | When it makes sense | What to expect |
|---|---|---|
| Send one more short follow-up | The person may have missed the first letter or asked for more time | Useful if the dispute seems fixable and you want to show patience |
| Try mediation | You both want a practical solution, not just money | Can be faster and less formal than court, but both sides have to participate |
| Use Judicaid | You want help drafting and organizing a settlement push before filing | Flat price of $34.99 per case; it is one option, not a guarantee |
| File small claims | You are ready to ask a judge to decide | Individuals can generally claim up to $12,500 |
| Walk away | The claim is weak, the proof is thin, or the stress is not worth it | Sometimes the cheapest option is to stop spending energy on it |
Where would I file in Contra Costa County if the demand letter does not work?
Small claims matters in this county are heard in Martinez, Pittsburg, and Richmond. Which location makes sense can depend on local assignment and where the dispute or parties are connected, so check with the court before you go.
The Martinez courthouse is at 725 Court Street, Martinez, CA 94553, and the Pittsburg courthouse is at 1000 Center Drive, Pittsburg, CA 94565. Before making a trip from places like San Ramon, Brentwood, or Richmond, confirm the current filing and hearing information with the court because counter windows and phone coverage are limited.
Contra Costa says the filing clerk window hours are 8:00 a.m. to 4:00 p.m., with most clerks answering phones from 8:00 a.m. to 3:00 p.m.. The court's main phone number is (925) 608-1000. Those local details matter because if you wait until the last minute, a missed call or wasted drive can cost you another day.
Can I use the demand letter later in court?
Yes, in most cases you should bring it with you. Your demand letter can help show that you asked for resolution before filing and that the other side knew what you wanted.
Bring the letter, attachments, proof of sending, and any reply. If you filed after a written agreement went bad, also bring the contract and proof that your claim was filed within the general time period of 4 years. If it was an oral deal, be ready to explain the shorter general period of 2 years.
What mistakes should I avoid in a demand letter?
Do not bluff, exaggerate, or make threats you cannot back up. A sloppy or angry letter can make settlement harder and can look bad later.
- Do not demand things that were never promised.
- Do not list every possible complaint if only one or two matter.
- Do not use insults, sarcasm, or threats about arrest or immigration.
- Do not send your only originals; keep your records.
- Do not wait so long that the claim becomes stale under the general limits for written or oral agreements.
What if I want help writing the letter?
You have a few practical choices. You can write it yourself, ask a local legal aid or self-help resource what information to include, try mediation, or use a service like Judicaid to organize a clear settlement demand.
If you plan to file in Contra Costa, local logistics matter too. Since small claims hearings are in Martinez, Pittsburg, and Richmond and clerk access is limited to 8:00 a.m. to 4:00 p.m., with most clerks answering phones from 8:00 a.m. to 3:00 p.m., a clean letter sent early can save you a courthouse trip later.
Frequently asked questions
Do I have to cite the law in my demand letter?
No. You generally do not need to include statute names or legal arguments. It is usually enough to clearly explain what happened, what you want, and that California small claims requires a demand before filing under Code of Civil Procedure § 116.320.
Can I send the demand letter by email instead of mail?
You can, especially if email is how you and the other side usually communicate. But keep copies and any proof that it was sent and opened, because if the case ends up in one of the Contra Costa locations in Martinez, Pittsburg, and Richmond, you may want to show the judge that the demand was actually delivered.
What if I do not know which Contra Costa courthouse handles my case?
Check with the court before you go. Small claims matters are heard in Martinez, Pittsburg, and Richmond, and the court's main line is (925) 608-1000. That is worth doing because clerk windows operate during 8:00 a.m. to 4:00 p.m., with most clerks answering phones from 8:00 a.m. to 3:00 p.m..
Can I ask for more than the small claims limit in my demand letter?
You can ask for what you believe you are owed, but if you choose small claims later, individuals generally cannot recover more than $12,500 in that court. If your dispute is larger, think carefully before filing because your court choice can affect strategy.
Does a text message count as a demand?
Sometimes it can help show that you asked, but a formal letter is usually better. A letter is easier to print, easier to organize, and easier to explain in court if your case is later heard in Martinez, Pittsburg, or Richmond under Martinez, Pittsburg, and Richmond.
What if our agreement was only verbal?
You can still send a demand letter and still may have a claim. Oral agreements generally have a shorter time limit, usually 2 years, so do not drift. In your letter, describe exactly what was said, when, and what each side was supposed to do.
