Detect tampered and deepfake Quittance de Loyer (French Rent Receipt)
A quittance de loyer is the rent receipt a French landlord or agency must issue on request, stating the rent and charges a tenant paid for a month, and CAF housing benefit files, visa applications, and future landlords all use them as proof of paid occupancy. Because a quittance invents a tenancy as easily as it documents one, verification leans on arithmetic, signature plausibility, and reconciliation with the bank transfers behind the payments.

What a genuine quittance de loyer contains
A proper quittance names the landlord or agency and the tenant, identifies the property, and states the monthly rent, the charges, and the total paid for a named period, over the issuer's signature or stamp. A series of quittances should run month by month with amounts that stay stable except where the lease says otherwise.
CAF and visa files read quittances against the bail (lease) and the bank account that paid them, so the receipt's amounts, dates, and parties must cohere with the rent transfers and the lease terms. A quittance series whose totals never touch the tenant's bank account is the classic fabricated-tenancy pattern.
How quittance de loyer forgeries are made
Rent arithmetic
Rent plus charges must equal the total on every receipt, month after month. Series that drift, or totals that break the relationship while the lease holds steady, were retyped.
Signature and stamp plausibility
Each receipt should carry the same signature or agency stamp across the series. Signature printing that varies between receipts, or a stamp rendered identically flat each month, marks template assembly.
Bank-transfer reconciliation
Quittances prove nothing unless the money moved. Matching the stated totals against rent debits in the tenant's statements is the strongest check available, and unbacked months are the forgery pattern.
Series coherence
Receipts run consecutively with stable formatting, parties, and amounts. Gaps filled by receipts whose font or layout departs from the series, or numbering that restarts, localise the fabricated months.
What TamperCheck checks on a quittance de loyer
TamperCheck runs 200+ forensic checks across three layers and returns a risk score from 0 to 100 with plain-English findings tied to specific regions of the document. These three carry the most weight on this document class.
Arithmetic reconciliation
Stated totals are recomputed from their components, and running or cumulative figures are checked for continuity across periods. A single edited value breaks the chain even when the page still looks right.
Date and validity consistency
Issue, expiry, and period dates are checked against one another and against the file's own creation metadata, which catches backdating and validity extension.
Field-level forensics
Every text region is analysed in its own right rather than as part of one whole-page image. This catches the smoothed and feathered edits that whole-image Error Level Analysis misses entirely.
And many more checks
The three above are the layers that carry the most weight on a quittance de loyer. Every upload runs the full suite of 200+ checks regardless of document class, spanning file structure and metadata, pixel-level forensics, font and text rendering, optical and print characteristics, provenance signals, AI-generation signatures, and many more checks.
Who verifies a quittance de loyer, and why
French banks, landlords' agents, and housing benefit offices. In each case the document is being used to unlock money, access, or a legal status, which is exactly what makes it worth forging.
How to verify a quittance de loyer in 4 steps
Collect the series
Ask for the receipts covering the period in question plus the lease, so the series can be read against the terms it should follow.
Check the arithmetic
Confirm rent plus charges equals the total on each receipt, and that the amounts hold steady across the series.
Reconcile with the bank
Match the stated totals against rent transfers in the tenant's statements, month by month.
Run a forensic check on the file
A fabricated series is expensive to fake consistently, and the inconsistencies are regional. TamperCheck runs 200+ forensic checks including series coherence and signature analysis, returning a risk score from 0 to 100 with findings tied to specific regions of the image.
Frequently asked questions
Who must issue a quittance de loyer?
The landlord or managing agent must issue one free of charge on request for any rent the tenant has paid. A refusal to provide receipts for months a tenant claims to have paid is itself a signal worth weighing in a file.
Do quittances prove a tenancy exists?
They prove payments were acknowledged, and only as strongly as the signature behind them and the bank transfers underneath them. A complete file pairs the receipts with the lease and the tenant's statements, which is what makes fabricated series expensive to pull off.
What should a quittance de loyer contain?
The parties, the property, the period, the rent, the charges, and the total paid, over the issuer's signature or stamp. Missing period or total lines make the receipt unusable for CAF and visa files, and amounts that never reconcile with the tenant's bank account undercut the whole series.
How does TamperCheck verify rent receipts?
TamperCheck recomputes the rent and charges arithmetic across the series, checks signature and stamp consistency between receipts, and inspects individual receipts for figure-level edits. It returns a risk score from 0 to 100 with findings tied to specific regions.
