# Detect tampered and deepfake Employment Contract > An employment contract gets verified for one clause out of thirty: the remuneration clause. It is a multi-page signed instrument, so unlike a one-page letter it can be attacked page by page, with a single sheet replaced inside an otherwise genuine PDF and the signature page left untouched. Page numbering, initials, and clause cross-references are what hold the document together. TamperCheck analyses every page and processes the file ephemerally, storing nothing afterwards. **Canonical URL:** https://tampercheck.ai/documents-support/employment_contract **API document class:** `employment_contract` **Last updated:** 2026-10-07 --- ## What a genuine employment contract contains A contract of employment identifies two parties precisely: the employing entity by its legal name and registration number, and the employee by name and address. It sets out the job title, place of work, start date, whether the term is permanent or fixed and when it ends, the probation period, working hours, and the remuneration clause covering base salary, frequency, currency, bonus, commission, allowances, and equity. Leave, sick pay, notice on both sides, confidentiality, intellectual property, restrictive covenants, and governing law follow, closing with signature blocks and schedules. A contract holds together by cross-reference. Clauses cite other clauses by number, defined terms are capitalised and used consistently throughout, salary usually appears in both numerals and words, and pages are numbered against a stated total with initials on each one. Replace a page and the numbering, the initials, or a reference to a clause that has quietly shifted will stop lining up. The start date has to sit sensibly against the signature dates, and the notice period has to be compatible with the term the contract sets. ## How employment contract forgeries are made ### Remuneration clause rewrite The salary figure in the pay clause is raised to clear an affordability or visa threshold. Where the amount appears in numerals and again in words, forgers regularly update one and miss the other, which leaves the contract stating two different salaries inside a single sentence. ### Page substitution One page of a multi-page PDF is swapped for a re-rendered version carrying different terms, leaving the signature page intact. The replaced sheet often differs from its neighbours in embedded font subsets, page dimensions, or image compression, even when it looks identical on screen. ### Signature block transplant A signature and the name and title beneath it are lifted from another document and placed onto a contract the signatory never saw. A transplanted signature is pixel-identical everywhere it is reused, whereas a genuine one differs every time it is written. ### Initial forgery across pages Contracts initialled on every page are meant to show a person working through the document. Copied initials repeat exactly, with the same stroke widths and the same position relative to the page margin, which real initialling never does across a dozen sheets. ### Term and start date edits A start date is moved back to manufacture tenure for a background check, or a fixed term is extended so the contract outlasts the loan or visa it supports. Both leave dates that sit oddly against the signature dates and the contract's own notice provisions. ### Template contracts naming a real employer A generic contract is downloaded, the employer's name and logo added, and the result presented as a real agreement. These fail on details an outsider cannot know: the entity's registered name and number, the internal clause structure, and who actually signs contracts there. ## What TamperCheck checks on an employment contract 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. ### Signature forgery analysis Signature regions are assessed for ink consistency and for how the stroke sits on the page, which distinguishes a genuine pen stroke from a pasted image of one. ### Reference and document number checks Document, account, and reference numbers are checked for issuer format conformance and against every other place the same value appears on the page. ### 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 an employment contract. 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 an employment contract, and why Lenders, immigration officers, and background screeners confirming employment. 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 an employment contract in 4 steps 1. **Check the fields against each other.** Read salary and benefits, contract term, and employer signature together rather than one at a time. Forgers typically change one value and leave the rest of the document describing the original. 2. **Inspect the file metadata.** Open the document properties and look at the producer, creation date, and modification date. A document produced by a consumer PDF editor, or created long after the date printed on its face, is worth a closer look. 3. **Ask for a second document.** Request a corroborating document from the same issuer or an adjacent period. Forgery effort concentrates on one file, so inconsistencies surface as soon as there are two to compare. 4. **Run a forensic check.** Manual review catches obvious edits but not field-level pixel manipulation or synthetic generation. TamperCheck runs 200+ forensic checks on an employment contract and returns a risk score from 0 to 100 within seconds, at $0.50 per document. ## Frequently asked questions ### How do banks verify an employment contract? Banks read the remuneration clause against corroborating documents rather than trusting it: payslips, salary credits on the bank statement, and where available a tax form for the same period. They confirm the employing entity's legal name and registration number resolve to a real company, check that the signatory can bind it, and look for page-level inconsistency across the PDF. ### Can an employment contract be altered to show higher salary? Yes, and it is the commonest alteration made to this document. The edit is usually confined to the remuneration clause, so the rest of the contract stays genuine and reads perfectly. Two things catch it: the amount written in words disagreeing with the amount in numerals, and the salary failing to match the payslips and bank credits filed alongside it. ### How do I check whether a page was replaced in a contract PDF? Compare the pages against each other instead of reading them in order. A substituted page commonly differs in embedded fonts, page dimensions, image compression, or the exact position of headers and footers, and its initials or page numbering may break the sequence. TamperCheck performs that comparison across every page and reports which one does not match the rest. ### Which parts of an employment contract are forged most often? Salary, contract term, start date, and the employer's signature, in that order. Salary drives lending and visa decisions, the term determines whether income looks durable, the start date manufactures tenure for background screening, and the signature is what makes the other three appear agreed. Each is a small edit inside a document that is otherwise entirely genuine. ## Related document types - Payslip: https://tampercheck.ai/documents-support/payslip - Salary Certificate: https://tampercheck.ai/documents-support/salary_certificate - Bank Statement: https://tampercheck.ai/documents-support/bank_statement - Tax Form: https://tampercheck.ai/documents-support/tax_form - Tax Return: https://tampercheck.ai/documents-support/tax_return - Offer Letter: https://tampercheck.ai/documents-support/offer_letter --- Try TamperCheck now: https://tampercheck.ai/dashboard · Docs: https://tampercheck.ai/docs · Pricing: https://tampercheck.ai/pricing
