A candidate accepts. Contracts go out. Then the right to work check comes back with a passport in one name and a National Insurance letter in another, and onboarding stops while somebody works out whether that is a problem.
It happens more than most HR teams expect. Marriage and divorce account for the bulk of it, but so do gender transition, anglicising a name after moving to the UK, dropping a middle name, and spellings that were wrong on the birth certificate and never corrected. In each case the person is exactly who they say they are. The paperwork has not caught up.
What the check actually requires
A manual right to work check is three steps, all completed before employment begins: obtain the original documents, check them, copy them. Get it right and you establish what the guidance calls a statutory excuse, your defence against a civil penalty that now runs to up to £60,000 per illegal worker, alongside the risk of a criminal conviction in serious cases.
Buried in Step 2 is the sentence that resolves the name problem. The employer's guide requires you to be satisfied that: "the reasons for any difference in names across documents can be explained by providing evidence (for example, original marriage certificate, divorce decree absolute, deed poll). These supporting documents must also be photocopied, and a copy retained."
Two of those three documents every HR team has handled. The third, a deed poll, is the written record of a name change with no marriage or divorce certificate behind it. It is what a service such as UK Name Change issues, and it is on that list precisely because so many name changes have no other paperwork.
Two things follow, and HR teams tend to get one or the other wrong.
A name mismatch is not a red flag. It is a documentation step. There is no basis for pausing a start date over it, provided the evidence exists and you take a copy.
A verbal explanation is not enough. "She got married last year" noted on a file does not satisfy the guidance. The supporting document has to be copied and retained on the same terms as the right to work documents themselves: for the duration of employment and two years afterwards, then securely destroyed.
Where it actually bites
A current passport in the married name raises nothing, because it is one document and agrees with itself.
The mismatch shows up in the combination checks: a birth or adoption certificate together with an official document showing the person's permanent National Insurance number and name. That pairing is where a name change surfaces. The birth certificate carries the name at birth, the NI letter or P45 the name in use now, and the two do not match.
It also shows up when an online check returns the name held by the Home Office and your payroll record was set up years earlier under something else.
The awkward case
Usually the evidence is easy: a marriage certificate, or for a reverted name the decree absolute alongside it.
The difficult conversation is with the employee who simply started using a different name years ago and never documented it. No marriage, no court order, nothing to photocopy. They are not doing anything wrong: using a new name is entirely lawful in the UK without any document at all. But "lawful" and "evidenced" are different things, and your file needs the second one.
That is the case the deed poll exists for. It is not a court process and does not need a solicitor. An unenrolled deed poll, signed and witnessed, is the document the guidance names, and it can be turned around in a day. Worth knowing before you tell a new starter their offer is on hold.
A short checklist
- Ask at offer stage, not day one. The question "will all your documents show the same name?" costs nothing in an offer pack and saves the week you would otherwise lose.
- Accept the standard evidence: marriage or civil partnership certificate, decree absolute, deed poll. Do not ask for more than the guidance requires.
- Copy it and file it with the right to work copies, and keep it as long as you keep those.
- Keep payroll on the legal name. HMRC needs the name the person legally holds. A preferred name belongs in your HR system, not on the P60.
- Run the same process for everyone. Name changes fall disproportionately on women after marriage and on trans employees, and there is a statutory code of practice on avoiding discrimination in right to work checks for a reason. Treating a mismatch as suspicious rather than administrative is its own risk.
None of this needs to delay a start date. It needs one question asked early, and one photocopy taken.
