Verify before accusing
Similarity alone is not always plagiarism. Gather the suspected original source and compare the work carefully.
Preserve evidence
Save the delivered files.
Record the source of the suspected original.
Keep relevant messages and scope documents.
Document what originality or licensing was promised.
Avoid altering the evidence before the dispute is understood.
Stop using questionable work
If ownership is uncertain, avoid publishing or distributing the material until the issue is resolved.
Ask for an explanation
Give the freelancer an opportunity to explain licensed assets, references, collaboration or other circumstances.
Portfolio theft and delivery plagiarism are related warning signs.Both are reasons to strengthen verification before future engagements.
Review available remedies
Depending on the agreement and hiring channel, options may include replacement work, refund discussions, platform disputes or professional legal advice for serious cases.
