Lease Signing Evidence Checklist: What to Save Before You Get the Keys

Quick answer
A lease file should prove what was advertised, what was negotiated, what the final contract says, what money changed hands, and which version each person actually signed. Save the listing, application, approval, draft lease, final lease, addenda, payment records, identity/contact information for the landlord or agent, and the messages that resolve any disputed term.

Key takeaways

• Evidence begins before the lease exists; the listing and approval terms can explain later discrepancies.
• Keep the final signed PDF outside the landlord's portal.
• Preserve proof of payment with the purpose of each payment, not just a bank total.
• A change log is more useful than a folder full of unlabeled draft leases.
• Separate “facts proved by records” from “legal conclusions that still need local verification.”

The seven-document lease file

1. The listing or offer

Save the advertisement as a PDF or full-page screenshot showing the address, advertised rent, included utilities, incentives, parking, furnishings, pet terms, and date captured. Listings change or disappear quickly.

2. The application and screening record

Keep the application you actually submitted, consent forms, receipts, and any credit/background-check documents provided to you. In New York, the current statute and Attorney General guidance impose specific limits and documentation requirements on credit/background-check fees. In British Columbia, application and processing fees are prohibited by statute. If money was collected, preserve the receipt and description of the payment.

3. The approval or offer message

An approval email often contains the practical deal: rent, start date, deposit, concession, parking, pet approval, or deadline to accept. Save the full message with sender and date.

4. Every material lease draft

You do not need to preserve twenty identical PDFs, but keep the first meaningful draft and the final version. If a clause changes, keep the intermediate version that shows the change.

5. The executed lease and addenda

Download the final signed agreement, not only the “completed” notification. Confirm signatures, page count, schedules, building rules, parking addenda, pet addenda, guaranties, utility riders, and any concession letter.

6. Payment evidence

For each payment, record amount, date, recipient, method, and stated purpose. A $3,000 transfer means little if nobody can later tell whether it was first-month rent, deposit, a holding payment, or multiple items combined.

7. Clarifications and corrections

If the final document conflicts with the listing or approval, save the message that resolves it. Better still, make sure the resolution appears in the signed lease or addendum.

File naming that survives a dispute

Use names that explain themselves, such as:

• 2026-09-12_listing_123-main-st.pdf
• 2026-09-20_approval-email.pdf
• 2026-09-22_lease-draft-v1.pdf
• 2026-09-23_lease-final-executed.pdf
• 2026-09-23_security-deposit-receipt.pdf

Do not overwrite drafts with the same filename. A version history can prove that a disputed clause appeared only after approval.

What screenshots miss

A cropped text can hide the sender, date, surrounding messages, attachments, or URL. When a conversation matters, preserve the entire thread or export it. If a portal allows document download, take the actual PDF. If a message contains a link to a document, save both the message and the document.

Worked scenario: the missing concession

A tenant's approval email promises “one month free on a 12-month lease.” The first lease draft contains no concession. A leasing employee texts, “Don't worry, accounting knows.” The tenant should not rely on that reassurance alone. The evidence file should include the listing, approval email, lease draft, text, and a written request for a corrected lease or signed concession addendum. If the concession is inserted, save the final executed version and payment ledger showing how the credit will be applied.

Evidence gaps that create avoidable problems

• Only the signature page was saved, not the entire lease.
• The tenant has a portal link but no downloaded copy.
• The landlord has a payment total but no record of what each payment represented.
• A pet or parking promise exists only in a phone call.
• The parties changed a clause by email but never identified which lease paragraph was amended.
• A move-in checklist exists, but it is unsigned and cannot be tied to the date possession began.

Jurisdiction notes worth preserving

In British Columbia, the Residential Tenancy Act requires a written tenancy agreement with specified information and says the landlord must give the tenant a copy within 21 days after entering into it. The province's standard RTB-1 form includes the statutory standard terms.

In New York, the Attorney General's guide recommends written agreements to avoid disputes, explains that a party must sign the lease to be bound by its terms, and describes additional protections for certain rent-regulated tenancies. New York's plain-language statute also applies to covered residential leases.

FAQ

Do I need to print everything?

No. A well-organized digital folder with reliable backups is usually easier to search. Keep originals when available.

Are screenshots of the listing worth saving?

Yes, especially if the listing describes included utilities, parking, furnishings, or incentives. Capture the address and date, not just a cropped marketing phrase.

Should I save rejected lease drafts?

Save any draft that contains a material term later changed or disputed. You do not need endless duplicates.

Is a recorded phone call good evidence?

Recording laws vary. Do not assume a recording is lawful. A safer general practice is to send a written summary after an important call and ask the other side to correct any misunderstanding.
