China's 2023-11 accession to the Convention Abolishing the Requirement of Legalisation for Foreign Public Documents made every law-firm newsletter. For trademark filings it changed nothing—filing never required legalization in the first place.
The Convention replaces the old chain of consular legalization for public documents with a single certificate. For companies litigating in China—where proof of legal status and evidence formed abroad face real formalities—that is a genuine simplification, and it deserved the coverage. What went wrong was the leap in the hundreds of summaries that followed: “document formalities for Chinese trademark filings just got easier.” They did not get easier. They were already this easy: a plain copy, a translation, a signature.
An Apostille certifies the origin of a public document. A power of attorney is a private document—to get it onto the Apostille track you would first have to notarize it, and the certificate would then vouch only for that notary, not for the power of attorney itself. The filing stage requires neither step: what it wants is the signed form itself. That is why our engagement process can send you the power of attorney today and file as soon as it comes back signed—there is no notary appointment on the critical path.
In court. In litigation, proof of legal status and evidence formed abroad must clear real formalities—and that is exactly where the 2023 accession helps. In administrative review proceedings the requirement is conditional: it attaches only in specific situations, not across the board. In the filing procedure there is none at all. These are three different procedural worlds; most English-language checklists flatten them into one, and the flattened version always lands on “to be safe, legalize everything.” Safe for whom is a fair question—that advice adds weeks and fees to a step that needs neither.
The good news has one real wrinkle: India objected to China's accession, so the Convention does not operate between China and India. An Indian company litigating in China still takes its documents down the old consular-legalization road. For filing, though, the analysis above holds exactly as written—that checklist has never asked an applicant of any nationality for legalization.
Those three items, plus one detail that genuinely does trigger a correction notice: the power of attorney must state the principal's nationality—a box to fill in, not a ceremony. The full guide has the document trail and sources; how to engage us shows where the power of attorney sits in the five steps.
