The credential requirement turns on whether the qualification itself matches the listed profession, not on the name printed on it. A former surname is an identity-linking question rather than a credential deficiency, but the file still has to establish that the diploma belongs to the applicant.
Treat it as identity evidence, not a credential gap
Confirm first that the degree, diploma or licence corresponds to the profession being claimed and to the duties described in the offer, since that analysis is unchanged by a name change. Then handle the name separately, with the civil documents that connect the two identities. Where the credential itself is an uncertain fit for the listed profession, that is a question for counsel on its own merits.
Sequence matters here as much as substance. Settle the credential question before paying for registry copies, because a qualification that does not match the listed profession will not be rescued by a flawless identity chain, and those copies would then buy nothing. Once the fit is confirmed, the name work runs on its own clock: an evaluator asked to report on a degree should be told about both names at the outset, since a report issued in one name and a passport in another creates a second linking problem stacked on the first.
Raise the former name in the opening exchange with the evaluator rather than correcting a finished report.
