Fake Employment Contract Detection Lending Fraud Guide

A fake employment contract is a fabricated, altered, or AI-generated version of a permanent contract, fixed-term contract, or job offer letter, submitted to a lender to misrepresent an applicant's employment status, tenure, or income stability. Unlike a payslip, which mainly evidences pay, an employment contract is used to prove the type of employment — permanent versus fixed-term, probationary versus confirmed — which directly affects how a lender scores affordability risk. This article covers what makes contract fraud distinct from fake payslip detection and fake tax notice fraud, which we have covered elsewhere in this series, and sets out the forensic signals and regulatory obligations specific to this document type.

Why Employment Contracts Are Now a Primary Fraud Target

Employment contracts are targeted because they let an applicant convert a precarious job into an apparently stable one without needing to falsify a full income history. According to Experian's fraud data, an estimated 84 in every 10,000 UK mortgage applications show indicators of fraud, contributing to roughly £1.3 billion in annual losses across the mortgage market (Experian, cited in industry fraud reporting). Cifas, the UK's fraud prevention data-sharing service, has separately flagged false employment and income misrepresentation as the most commonly recorded fraud type in mortgage applications (Cifas Fraud Risk Focus).

A specific and under-reported pattern is contract-type misrepresentation: an applicant on a genuine but fixed-term or probationary contract submits a document altered to read "permanent" — a single word change that shifts a marginal application from decline to approval in many affordability models. Because the underlying employer and salary are real, this form of fraud is harder to catch than a wholly fabricated employer, and it rarely appears in payslip-only checks since payslips do not usually state contract type.

Three applicant profiles account for most contract fraud referred to lenders: those inside a probationary period who remove the probation clause, those on genuine fixed-term contracts who change the end date or contract type, and those with a verbal or informal job offer who fabricate a formal offer letter before their actual start date.

How Fraudsters Fabricate Employment Contracts

Fabrication ranges from a copy-paste edit of a real document to a fully AI-generated contract with no underlying employment at all. Four techniques dominate cases referred to UK lenders in 2026.

Template and word-processor editing of a genuine document. The applicant opens their real contract in a PDF editor and changes specific fields — contract type, end date, job title, salary band — leaving surrounding text and letterhead untouched. This is the most common method: it requires no technical skill and preserves an otherwise-authentic document structure, defeating visual review.

Full AI generation with cloned employer branding. Generative tools can reproduce a named employer's letterhead, logo, HR signature block and standard clauses from public job adverts or LinkedIn pages, producing a contract for a relationship that does not exist. These documents are typically internally consistent but fail on external cross-checks.

Fabricated or borrowed company registration details. Contracts reference a company name and sometimes a company number in the header or signature block, checkable against the free Companies House register. Fraud rings either invent a number, transpose digits from a real one, or copy the registration details of an unrelated dormant or shell company that has no connection to the applicant's claimed role.

Forged or scanned-and-pasted signatures. Genuine e-signed contracts (DocuSign, Adobe Sign, HelloSign) embed a certificate and audit trail; a forged contract typically shows a signature image with different compression artefacts, resolution or anti-aliasing from the surrounding text — evidence that the signature was pasted in from a separate source rather than applied by the signing platform.

Forensic Signals That Expose a Fake Contract

The signals that reliably separate genuine from fabricated employment contracts fall into four categories: structural, cross-referential, cross-document and behavioural.

Cross-validating the contract against the applicant's payslips and bank statement deposits is the single strongest counter-measure, because a fabricated contract describing a permanent role at £48,000 cannot be reconciled with three months of bank credits consistent with a lower, irregular fixed-term wage. This is the same principle underlying AI document fraud detection techniques applied across payslips, bank statements and tax documents — no single document is assessed in isolation. A bare Companies House existence check is not sufficient alone, since fraudsters increasingly borrow the registration details of a real, active company in an unrelated sector; a business-activity consistency check is also required.

What Borrowers and Brokers Ask on Finance Forums

On mortgage and personal finance forums, three recurring questions expose both borrower misunderstanding and a genuine verification gap that lenders have to close.

On threads such as one on Mumsnet titled around altering a job offer to "borrow more" on a mortgage, posters have asked whether editing a contract to show permanent status before submission would realistically be noticed by a lender — with other forum members correctly pointing out that this constitutes fraud under the Fraud Act 2006, regardless of whether the underlying job and salary are genuine.

On MoneySavingExpert's forums, applicants have separately asked why a lender requests a full contract of employment in addition to payslips and bank statements, when the payslips alone appear to demonstrate income. The answer is regulatory: MCOB 11.6.26R prohibits mortgage lenders from relying on self-certified income, and a contract is the independent, employer-issued evidence of employment terms — permanent, fixed-term or probationary — that a payslip alone cannot establish (FCA Handbook, MCOB 11.6).

A third recurring question, from limited company directors, asks whether a contract of employment with their own company satisfies a lender's employment evidence requirement. It generally does not: lenders treat sole-director company income as self-employment, requiring independent evidence such as SA302s, company accounts, or accountant confirmation rather than a self-issued contract, precisely because that document is not independent of the applicant.

Regulatory Obligations for UK Lenders

UK consumer and mortgage lenders operate under overlapping duties that require employment evidence to be independently verified, not merely collected.

A lender that grants credit on the strength of an employment contract that was never independently checked against Companies House, metadata forensics or cross-document consistency is exposed to supervisory criticism under CONC 5.2A and, for mortgages, a direct breach of the MCOB 11.6 prohibition on relying on unverified declarations. Supervisory findings of inadequate income verification can lead to redress requirements and enforcement action.

Multi-Layer Detection in Practice

A layered protocol lets underwriting teams check every contract without extending processing times: OCR extraction of employer name, contract type, dates and salary; a live Companies House lookup; PDF metadata and signature-layer forensics; font and layout consistency checks around commonly-edited fields; and cross-document reconciliation against payslips and bank deposits.

AI-generation signal detection functions as a complement to existing structural controls — metadata forensics, Companies House lookups, arithmetic and cross-document checks — rather than a replacement for them. According to the ACFE 2024 Report to the Nations, manual review methods identify only 37% of document fraud, with an average detection delay of 87 days — a gap that, in mortgage lending, often means funds have already been advanced before the fabrication is found.

CheckFile applies this layered approach across employment contracts, payslips and supporting income documents for lending and KYC teams.

Criminal Penalties for Fabricated Employment Documents

Submitting a fabricated employment contract to obtain credit exposes the applicant, and anyone who helped produce the document, to criminal liability under English law. Fraud by false representation under the Fraud Act 2006, section 2 and producing or using a false instrument under the Forgery and Counterfeiting Act 1981 each carry a maximum sentence of ten years' imprisonment; a service that knowingly sells fabricated contracts can be prosecuted as an accessory. Beyond criminal exposure, a discovered fabrication typically leads to immediate withdrawal of the credit offer, a recorded Cifas fraud marker affecting applications for up to six years, and, for existing lending, acceleration or recall of the facility.

Frequently Asked Questions

Can a genuine employer's letterhead be used on a fake contract?

Yes. Fraudsters commonly copy a real employer's logo, address and HR signature block from a job advert or company website onto a fabricated contract for a role the applicant does not actually hold. Companies House cross-checks confirm the company exists, but only cross-document validation against payslips and bank deposits reliably exposes that no genuine employment relationship supports the figures claimed.

Is changing "fixed-term" to "permanent" on a real contract still fraud?

Yes. Even where the employer, salary and role are genuine, altering the stated contract type to misrepresent job security to a lender is fraud by false representation under the Fraud Act 2006, because it is a material change made to influence a lending decision. The underlying employment being real does not remove criminal liability for the alteration.

Why do lenders ask for a contract as well as payslips and bank statements?

A payslip evidences pay but not the type or security of employment. A contract is the independent, employer-issued document that establishes permanent, fixed-term or probationary status, which materially affects affordability risk scoring. FCA MCOB 11.6 prohibits mortgage lenders from relying on self-certified income, making an independently-sourced or independently-verified contract part of a compliant income evidence file.

Does a contract with your own limited company count as employment evidence?

Generally not on its own. Lenders classify income from a company where the applicant is sole or majority director as self-employment rather than employment, and typically require SA302s, filed company accounts, or accountant confirmation instead of a self-issued contract, because that document is not independent of the applicant.

What should a lender do if a submitted contract is suspected to be forged?

The lender should preserve the document and its metadata, decline or pause the application pending verification, and record the suspicion through internal fraud reporting processes. Where money laundering indicators are present, a Suspicious Activity Report may be required under the Money Laundering Regulations 2017, and suspected fraud should also be reported to Action Fraud.
