the most you can generally claim in California small claims court
The basics
- Court
- Small Claims Court, a division of the Superior Court in each county
- Limit
- Up to $12,500 for an individual. You can file only two claims over $2,500 in a calendar year.
- Filing fee
- Between $30 and $100, depending on the amount and how many claims you've filed. You can ask for a fee waiver.
- Where to file
- Usually the county where the landlord lives or does business, or where the rental is.
- Lawyers
- You can get advice from a lawyer beforehand, but neither side can have a lawyer represent them in court.
Before you file
- Ask in writing first. A judge will want to see that you gave the landlord a chance to pay.
- Work out the total: the amount withheld, plus up to twice the deposit if you'll argue bad faith. Everything you claim must fit under the limit.

Haven't sent a demand letter yet?
It's the step judges look for, and often the one that gets you paid. Get a letter citing California Civil Code § 1950.5, sent by USPS Certified Mail if you like. See it free first.

If a court finds the landlord kept the deposit in bad faith, it may award statutory damages of up to twice the amount of the deposit, in addition to actual damages (Civ. Code § 1950.5(m)).
For example, if a landlord kept all of a $1,800 deposit, the most a court could award under the statute is about $5,400, if it finds the landlord acted in bad faith. Courts decide penalties on the facts, so ask for what the statute allows and be ready to explain why it applies.
Everything you claim, penalties included, has to fit under the court's limit, or you give up the excess by filing there.
Step by step
- Fill out the claim. Form SC-100, Plaintiff's Claim and ORDER to Go to Small Claims Court, with the landlord's correct legal name (check your lease or the owner on record).
- File it with the court clerk. In person, by mail or online where your court allows it, and pay the fee. You'll get a hearing date.
- Serve the landlord. Someone over 18 who isn't part of the case, a process server or the sheriff delivers the papers, and files proof of service.
- Prepare your evidence. Organize it by date. Bring three copies of everything: one for you, one for the judge, one for the landlord.
- Go to the hearing. Tell the judge what you paid, when you moved out, what you got back and when, and which rule was broken. Keep it short and factual.
The landlord has the burden of proving that the amounts they kept were reasonable (Civ. Code § 1950.5(m)).
What to bring
- Your lease
- Proof of the deposit: receipt, canceled check or bank record
- Move-in and move-out photos or video
- The itemized statement, if any, and its postmark
- Your demand letter and its Certified Mail receipt
- Texts and e-mails with the landlord
Put everything in date order. Judges hear many cases a day, and a clear timeline is the most persuasive thing you can bring.
