California Security Deposit Evidence Checklist

Start with a one-page case map

Before collecting every file, write the five facts that orient the dispute: rental address, parties, deposit amount, move-out date, and amount still in question. Add the day-21 date and the date the accounting arrived.

This map keeps your evidence from becoming another pile. Every later document should connect to a date, deduction, payment, condition, or request on the map.

Folder 1: tenancy and deposit

California law permits credible evidence to establish the existence and amount of a deposit, including a canceled check, receipt, lease, consistent statements or actions, and qualifying sworn evidence. Keep the clearest proof first.

• Signed lease and addenda
• Receipt, canceled check, bank record, or other proof of the deposit
• Move-in checklist and inspection report
• Notices ending the tenancy
• Forwarding address or agreed electronic return instructions

Folder 2: condition and inspections

Name files by date, room, and subject. A filename such as 2026-06-04-kitchen-counter-move-out is more useful than IMG_4827. Keep original files in a separate folder so metadata is preserved.

• Original move-in photographs and video
• Repair requests showing preexisting or developing conditions
• Initial move-out inspection request and statement
• Move-out photographs and walkthrough video
• Landlord photographs before and after repair or cleaning

Folder 3: accounting and support

Do not combine the estimate and final invoice into one entry. The dates and changes between them may be relevant to the accounting timeline.

• Deposit refund or transfer confirmation
• Itemized statement
• Bills, invoices, receipts, and vendor information
• Landlord or employee work description, time, and hourly rate
• Materials and supply documentation
• Good-faith estimate and later final documents

Folder 4: communication and delivery

Export or screenshot the relevant parts of email and message threads, but preserve enough context to show sender, recipient, date, and subject. Save demand letters in their final sent form with attachments and delivery proof.

Write a dated note for important phone calls. Identify who spoke, what was said, and what follow-up was promised. A contemporaneous note is usually more useful than trying to remember the conversation months later.

Turn the folders into an evidence index

1. Assign each record an exhibit number.
2. Give it a date and plain-language title.
3. State the single fact it supports.
4. Link it to a timeline event or deduction row.
5. Mark whether it came from you, the landlord, or a third party.

Your evening is not the filing system

A dispute feels heavier when the record lives across a camera roll, inbox, text thread, and desk drawer. The objective is not perfect paperwork. It is a file another person can understand without borrowing your memory.

RentClaw is built to organize these materials into a review-ready self-help packet. It does not evaluate credibility, determine liability, or replace legal advice.

How this checklist was reviewed

This checklist was reviewed on August 9, 2026 against the current text of California Civil Code section 1950.5, the California Courts security-deposit guide, and California Courts guidance on preparing proof. Each folder maps to a date, amount, condition, communication, or supporting-document question found in those official sources.

The checklist is an organizational framework, not a statement that any item proves liability. Editors and resource librarians may cite it as a practical evidence-index model while linking the official sources below for the governing rules.
