Every document and account to update after you get married

The list reads as longer than the work actually is. Most of it is a scan of the marriage certificate attached to a short standard message, and a large share can be done online in an evening. What matters is writing the list down once, in full, rather than discovering it piece by piece over a year. This article groups every organisation by urgency, names the evidence each one wants, and marks the few places where a real deadline exists.

These come first because everything else asks to see the result of them.

The American DMV deadline is the single item on this whole list that can produce a penalty, and it is set by each state rather than federally. Look up your own before you assume you have time.

Note what never changes anywhere: your birth certificate, your degree certificates, your professional qualifications, your Social Security number or National Insurance number. Those record a fact or an identity, not a current name.

No legal deadline here, but a practical one. If the name on your account does not match the name on your payroll record, payments can be rejected.

• Employer and payroll — before the next pay run. Payroll cut-off is often mid-month, so telling HR on the 20th means the change shows on the month after next.
• Banks, credit cards, brokerage accounts — new cards take one to two weeks. Until they arrive, expect occasional questions at hotel check-in and car rental desks, where card and ID are compared.
• Mortgage or landlord, and any loan agreements — the name of the contracting party matters when you refinance.
• Tax authority — in the UK usually automatic through your employer; in the US the IRS matches your return against Social Security records, which is exactly why the SSA step comes first. A mismatch delays a refund.
• Pension providers and retirement accounts — and while you are there, check the beneficiary.

That last point deserves its own sentence. Beneficiary designations on life insurance, pensions and retirement accounts override a will in most jurisdictions, and marriage does not update them. If yours still names a parent or an ex-partner, that is who inherits. It takes ten minutes to fix and is the most consequential item on this page.

Weeks four to eight. Not optional, because in a claim the name on the policy has to match your ID.

1. Home and contents insurance — and this is the moment to combine two policies into one, since two policies on one household pay twice and only cover once.
2. Car insurance — in the US, merging vehicles onto one policy usually reduces the premium. In the UK, a no-claims bonus is personal and generally cannot be transferred to a spouse; adding them as a named driver is the normal route, and misrepresenting who mainly drives the car is fraud.
3. Health insurance — in the US, marriage is a qualifying life event opening a special enrolment period, typically 30 days on employer plans and 60 days on the marketplace. Miss it and you wait for open enrolment. This is a real deadline.
4. Life, income protection and critical illness cover.
5. Utilities, broadband, phone, subscriptions, TV licence.
6. Professional bodies, unions, licences to practise.

For most of these a scanned certificate and a short message is enough. The part that genuinely takes time is finding the account numbers, not writing the messages.

While you are in the insurance folder, look for cover you are now paying for twice rather than only renaming it. Two contents policies on one address, two breakdown memberships, two travel insurance policies and two cell phone insurances are the usual suspects. Cancelling the newer of a pair is normally straightforward, and the saving is often larger than anything the tax system offers a newly married couple.

Individually trivial, collectively the reason the process drags on. Work through them in one sitting rather than as they occur to you.

• Frequent flyer and loyalty programmes — important, because the name has to match your passport at check-in
• Doctor, dentist, optician, pharmacy, any repeat prescription
• Children’s school or daycare, if applicable
• Gym, clubs, library, alumni associations
• Online accounts with stored payment methods
• Electoral roll (UK) or voter registration (US)
• Will, power of attorney and advance directive — not because of the name, but because marriage changes what they do
• Your building manager, doorbell, letterbox and neighbours

The last one sounds trivial and is not. A letterbox that does not carry the new name gives postal workers grounds to return mail addressed to it — including, with some irony, your new passport.

One further piece of sequencing: if a change of name also means a change of email address, do not do both at once. Keep the old address running as an alias for at least six to twelve months. Account recovery for dozens of services points at that mailbox, and closing it early is how people lock themselves out of their own accounts.

The trick is to work in batches rather than organisation by organisation. Prepare once, then send everything in sequence.

1. A good scan of the marriage certificate as a PDF. You will attach it fifteen times.
2. One short standard message giving the old name, the new name, the date of marriage and a request for written confirmation. Only the account number and the greeting change.
3. A list of every account with its reference number and contact route. If you do not have one, the fastest way to build it is to read the last twelve months of bank statements: every recurring counterparty is there, including the ones you have forgotten.
4. A column for replies. An item is only done when confirmation arrives, not when the message goes out.

Starting from bank statements rather than memory is what makes the list complete. And when it comes to telling people rather than institutions, a line on your wedding website does the job in one go, instead of correcting the spelling of your surname in a hundred separate conversations.
