# Detect tampered and deepfake Power of Attorney

> A power of attorney is the instrument behind most elder financial abuse, because it turns one signature into spending authority over someone else's assets. The fraud takes two shapes. One is an instrument the principal never executed. The other is a real one whose granted powers were widened after signing, so a narrow authority over a pension becomes authority to sell a house. Banks and registries act on both. TamperCheck examines the notarisation, the scope clause, and the page continuity between them.

## What a genuine power of attorney contains

A power of attorney identifies the principal by full name, address, and identifying document, names the attorney or attorneys and where they live, and then enumerates the powers granted: operating accounts, dealing with specified property, tax and benefit matters, health decisions where the jurisdiction permits. Limitations and exclusions follow, along with commencement, expiry or a durability clause covering incapacity, and the terms on which it can be revoked. It closes with the principal's signature and date, witness blocks giving names and addresses, a notarial certificate and seal, and a registration endorsement where one is required.

The enumerated powers are where the whole value sits, and the execution formalities exist to bind them to a moment in time. The notarial certificate names the principal and fixes a date on which an officer watched them sign, so the execution date must sit before any record of the principal losing capacity and inside the notary's commission period. Witnesses are generally barred from being the attorney or benefiting under the instrument, so those names must not overlap. Numbered and initialled pages fix how many pages of powers were actually granted.

## How power of attorney forgeries are made

### Scope widened after execution

Powers are added to the enumerated list, or a limitation is deleted from it, on an instrument the principal did sign. The signature, witnesses, and notarial certificate stay genuine, which is what gets it past a bank. The added lines usually disturb the spacing and numbering of the list they were inserted into.

### Powers page substituted

In a multi-page instrument the page carrying the schedule of powers is reprinted and swapped, leaving the signature and attestation pages untouched. Page initials are the check that catches this, because the replacement either loses them or reproduces a copy of an initial that already appears elsewhere in the document.

### Principal signature forgery

The signature is traced from a specimen or copied from another document the principal signed. A traced signature moves at the wrong speed, so pen pressure and stroke width stay unnaturally even, and a copied one arrives carrying the paper tone of its source.

### Backdated execution

The execution date is moved to a point before the principal lost capacity, so an instrument signed too late appears to have been signed in time. This is the central manoeuvre in contested elder abuse cases, and the printed date is then contradicted by the notarial block, the witness details, and the file's own metadata.

### Fabricated notarial and witness blocks

Witness names and addresses are invented, or both witness signatures come from the same hand, and a notarial certificate is assembled to sit under them. Where the commission number is also invented it fails the commissioning authority's format, and where it is borrowed the expiry date rarely matches the execution date above it.

### Instruments produced entirely from a template

A complete power of attorney can be assembled from a precedent and filled in for a principal who never saw it. Nothing inside it contradicts anything else, so internal checks pass, and it is caught instead on the physical evidence: text rendered uniformly across every page, and a seal with no impression behind it.

## What TamperCheck checks on a power of attorney

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.

### Embossed seal analysis

A physically embossed seal deforms the paper it sits on. A seal that was scanned and reprinted is flat, and the two separate cleanly under analysis even when they are hard to tell apart by eye.

### 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 power of attorney. 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 power of attorney, and why

Banks, registries, and care providers acting on delegated authority. 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 power of attorney in 4 steps

1. **Insist on the original or a certified copy.** Work from the executed original or a copy certified by the notary or solicitor who holds it, not a scan forwarded by the attorney. Original instruments carry embossing, page initials in wet ink, and binding marks, none of which reproduce, and a refusal to produce one is itself informative.
2. **Check the register and check for revocation.** Where the jurisdiction registers powers of attorney, search the register for the instrument and confirm it is recorded, current, and not revoked. Property powers are often also recorded at the land registry. A power that was validly granted and later revoked looks identical on paper to one still in force.
3. **Verify the notary and speak to the principal.** Confirm the notary's commission number and expiry against the commissioning authority's register and that they were commissioned where the certificate says the signing happened. Where the principal can still communicate, contact them directly rather than through the attorney, and confirm the scope they believe they granted.
4. **Run a forensic check on the document itself.** Registry and notary checks confirm an instrument exists; they do not show whether the copy in front of you matches it. TamperCheck runs 200+ forensic checks on a power of attorney and returns a risk score from 0 to 100 within seconds, naming the field or page that was edited, at $0.50 per document.

## Frequently asked questions

### How do banks verify a power of attorney?

Banks typically require sight of the original or a certified copy, check any registration endorsement, confirm the scope of the granted powers covers the transaction being asked for, and record the attorney's identity before acting. What most do not do is examine the document forensically, which is why a widened scope clause on an otherwise genuine instrument gets through.

### How common is power of attorney fraud?

It is one of the most frequently reported forms of elder financial abuse, and it is under-reported because the victim is often unable to notice or to complain. Most cases are not fabricated instruments but abuse of real ones, with the document forgery sitting at the boundary: powers added, limits removed, or an execution date moved back to cover a signing that happened too late.

### Can you tell if a power of attorney was signed after the person lost capacity?

Not from the document alone, but you can test whether the execution date is the date it claims to be. Backdating leaves the printed date at odds with the notarial block, the file's own timestamps, and the rendering history of the region that was changed. Establishing capacity itself needs medical records set against that date.

### What makes a power of attorney invalid?

A power of attorney is invalid when the execution formalities fail: no capacity at signing, missing or disqualified witnesses, an absent or defective notarial certificate, or a signature that is not the principal's. It also ends on revocation, on expiry, or on the principal's death. Forgery of the signature or of the notarisation voids it from the start.
