Security Deposit Evidence Checklist: What to Save Before a Dispute

Quick answer
A strong security-deposit file is not “lots of screenshots.” It is a small set of records that proves five things: what was paid, what the unit looked like at the start, what changed during the tenancy, what it looked like at the end, and how any deduction was calculated. Organize the evidence by date and purpose so another person can understand it without your memory filling the gaps.

Key takeaways

• Save original documents and files, not only cropped screenshots.
• Pair move-in evidence with comparable move-out evidence.
• Keep maintenance reports because delayed repairs can affect responsibility.
• Preserve the landlord's itemization and the underlying invoices, receipts, or quotes when available.
• Keep proof of how and when a forwarding address or demand was delivered.

The five evidence buckets

A. Money

Save the lease page that states the deposit, the receipt, bank transfer, cancelled check, payment-platform record, and any later agreement changing the amount. If the property changes owners or managers, keep communications showing who now holds the deposit.

B. Move-in condition

Keep the signed inspection report, inventory, key handover record, and photos or video. The goal is not to photograph every square inch; it is to document pre-existing marks and the condition of high-dispute areas such as flooring, walls, counters, appliances, bathrooms, windows, and furnished items.

C. Repair and maintenance history

A leak reported in March but repaired in June may matter to a later dispute about staining or flooring. Keep the first report, follow-up messages, access appointments, invoices you paid, and photographs showing progression.

D. Move-out condition

Repeat the move-in photo set as closely as possible. Keep cleaning receipts if cleaning is disputed. Save the move-out inspection report and any list of conditions the landlord asks you to correct before surrendering possession.

E. Deposit return and deductions

Keep the returned amount, itemized statement, envelope/postmark if timing matters, emails, invoices, photographs used by the landlord, and any contractor estimate. If a deduction is simply a lump sum, ask politely for the calculation.

Evidence index you can actually use

ID	Date	Record	What it proves	Original saved?	Linked issue
E-01	Move-in date	Signed condition report	Baseline condition	Yes	Flooring
E-02	Move-in date	Bedroom floor photo	Existing scratch near closet	Yes	Flooring
E-03	During tenancy	Repair email	Leak reported	Yes	Water stain
E-04	Move-out date	Matching bedroom photo	Scratch unchanged	Yes	Flooring
E-05	After move-out	Deduction statement	$650 floor charge	Yes	Flooring

Name files consistently, for example 2026-06-01_move-in_bedroom-floor_01.jpg. Consistent names make the record easier to audit than a camera roll of thousands of images.

How to handle screenshots

Screenshots are convenient but fragile. They may hide the sender, date, URL, message before/after, or attachment. When a message matters, save the full conversation or export it if the platform allows. If the platform may delete old history, back it up early.

For photographs, retain original files where practical. Do not alter an image to make a mark look worse or cleaner. If you crop a copy for explanation, keep the untouched original too.

Worked scenario: the cleaning deduction

A landlord withholds $300 for “deep cleaning.” The tenant has a move-out video and a $140 professional-cleaning receipt but no move-in cleaning record. The evidence file should not claim that the unit was “perfect.” It should show the receipt, the move-out condition, the lease's cleaning language, the landlord's itemization, and any invoice supporting the $300. The unresolved question is then narrow: what cleaning was actually needed, what did it cost, and does local law allow that deduction in these circumstances?

Evidence gaps that matter

• No proof that the deposit was paid.
• Move-in photos exist but cannot be dated or tied to the unit.
• Important damage is photographed only after move-out with no baseline comparison.
• A repair problem was discussed by phone but never confirmed in writing.
• The landlord's deduction statement is saved but the underlying cost documents are missing.
• The tenant says a forwarding address was sent but cannot show when or how.

FAQ

Should I record the move-in inspection on video?

Video can complement a written report and still photos. A slow walkthrough is more useful than a fast cinematic clip. Narrate room names and obvious pre-existing damage, but keep the signed report as well.

Can metadata prove when a photo was taken?

It can help, but metadata can be missing or altered when files are copied or sent through apps. Treat it as supporting evidence, not the only proof of date.

What if I have no move-in photos?

Use other contemporaneous material: the signed condition report, listing photos, maintenance requests, emails, witness knowledge, or landlord records. Do not fabricate a baseline.

How long should I keep the file?

Keep it at least through the time in which a claim or dispute can realistically be brought under the applicable local rules. Limitation periods vary, so confirm the jurisdiction-specific answer.
