Detect tampered and deepfake Guardianship or Custody Proof
Forged custody and guardianship documents are detected through the court that supposedly issued them: the case reference format, the seal and its sealing date, and whether the operative clauses actually grant what the person presenting them claims. These documents decide who may take a child across a border, so a forged one is a child protection matter before it is a paperwork problem. Officers see them at a counter, under time pressure, as a photocopy. TamperCheck gives them a written verdict.

What a genuine guardianship or custody document contains
A guardianship or custody document is an order of a court, and its authority sits in its operative clauses rather than its title. It names the issuing court, the case or reference number, the child by full name and date of birth, both parents, and the guardian or applicant. The numbered paragraphs that follow set out what is actually granted: sole or joint custody, residence, guardianship of the person or of property, any conditions attached, and any express permission for the child to travel or to hold a passport. The order date, the judge, the seal, and the sealing date close it.
The numbering is the structure that has to hold. Operative paragraphs run in an unbroken sequence, so a clause added to grant travel permission disturbs the count, the spacing, or the line leading around it. The child's name and date of birth have to match the passport presented at the counter, a claim of sole authority contradicts an order naming both parents as joint holders, and the sealing date cannot precede the date the order was made. Where a notarised consent letter travels with the order, its notary commission has to have been valid when it was signed.
How guardianship or custody document forgeries are made
Operative clause insertion
A paragraph granting permission to travel or sole authority over a child is added to a genuine order. Inserted clauses disturb the numbering sequence, the paragraph spacing, or the line leading of the page they land on, and the added text seldom matches the rendering of the text it sits between.
Guardian name substitution
The named guardian is replaced so an adult with no legal relationship to the child appears to hold authority over them. This is the version with the most serious consequences, because it is the one that moves a child across a border, and it changes only a few characters on an otherwise authentic order.
Court seal and sealing stamp copying
The seal and the court officer's sealing stamp are copied onto a fabricated order. Court seals are impressed or embossed and deform the paper, and the sealing date stamped alongside has to be consistent with the date the order was made and with the case number in the heading.
Page appending in a scanned order
Extra pages are added to a genuine scanned order, or one page is swapped, so the order appears to grant more than the court gave. Pages produced separately differ in skew, resolution, and compression from the scan they were joined to, even when the wording reads correctly.
Forged consent letters alongside a real order
The order is genuine and the notarised consent letter from the non-travelling parent is not. Signatures are copied from other documents, notary stamps are reused across unrelated files, and commission expiry dates frequently contradict the date the letter claims to have been signed.
Orders assembled from published templates
Court formats are published, so a complete order can be built with a plausible case number and names and dates that agree throughout. Nothing in the text contradicts anything else, and the check falls back on the seal, the print, and confirmation from the court named on the front page.
What TamperCheck checks on a guardianship or custody document
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.
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.
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.
And many more checks
The three above are the layers that carry the most weight on a guardianship or custody document. 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 guardianship or custody document, and why
Consulates and border officers assessing minor travel 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 guardianship or custody document in 4 steps
Read the operative clauses, not the heading
A document titled as a guardianship order may grant far less than the person presenting it claims. Work through the numbered paragraphs and establish exactly what authority is granted, over whom, for how long, and whether travel or passport authority is expressly covered.
Cross-reference the child against the passport
The child's full name and date of birth on the order have to match the passport being presented, character for character. Where a parental relationship is being claimed, check that the accompanying birth certificate names the travelling adult as a parent.
Confirm the order with the issuing court
Use the case reference and the parties' names to ask the court named on the order whether it exists, whether it remains in force, and whether it has been varied or superseded. Ask for a sealed copy rather than relying on the photocopy you were handed.
Run a forensic check before acting on it
Where a child's travel turns on the document, a clean review is worth having in writing. TamperCheck returns a risk score from 0 to 100 in about a minute with findings tied to the regions that failed, and processes the file ephemerally without storing it.
Frequently asked questions
How do consulates verify custody documents for minors?
They read the operative clauses and then confirm the order with the court that made it, using the case reference and the child's details. A consulate looks for express authority covering the specific journey, checks the order is current rather than superseded, and asks for a sealed copy rather than a photocopy. Where one parent travels alone, a notarised consent letter from the other is usually required alongside it.
Can a guardianship order be forged?
Yes, and because these orders decide who may remove a child from a country, a forged one is handled as a safeguarding matter rather than a documentary one. The common forms are a genuine order with an added clause granting travel permission, a real order with the guardian's name replaced, and a fabricated order from a court whose format the officer cannot recognise. Each leaves traces in the file.
What documents does a child need to travel with one parent?
Typically the child's passport, evidence of the relationship such as a birth certificate naming the accompanying parent, and either a court order granting sole custody or permission to travel, or a notarised consent letter from the parent who is not travelling. Requirements vary by destination and by carrier, and airlines often apply them more strictly than borders do.
How do you check a notarised parental consent letter?
Check the notary before the signature. A valid notarial act carries the notary's name, commission number, and commission expiry, and that expiry has to fall after the date of signing, while the seal should be impressed or embossed rather than printed flat. Then confirm the letter names the child, the travelling adult, the destination, and the dates, since vague letters are often genuine templates wrapped around a forged signature.
