How to Change Your Name After Marriage or Divorce in New Brunswick (2026)
In New Brunswick, most people do not need a formal legal name change after marriage. You can assume your spouse's surname simply by updating your ID with your marriage certificate. This guide covers the order of operations, the rules specific to New Brunswick, and a free downloadable checklist.
Assumed surname vs. legal name change
Assumed surname (what most people do): If you simply wish to use your new marital surname, bring your official marriage certificate and government photo ID to any Service New Brunswick service centre.
Legal name change (a separate, formal process): A legal name change through Vital Statistics Branch, Service New Brunswick is required only if you want to change the name on your birth certificate itself, or to adopt a name not covered by the assumed-surname rule.
Order of operations
Marry
Officiant registers the marriage with provincial Vital Statistics. This takes a few weeks.
Order your marriage certificate
From the province or territory WHERE you married (not the licence -- the registered certificate issued by Vital Statistics).
Update your SIN (Service Canada)
Free. Can run at the same time as step 4. Your SIN number does not change.
Update provincial driver's licence + health card
Critical: do this BEFORE the passport application. Use your marriage certificate.
Apply for a new passport (IRCC)
Only after provincial ID already shows the new name. Full fee -- no amendment option. Fee as of 2026-03-31: $163.50 (10-yr) / $122.50 (5-yr); indexes annually.
Update CRA, banks, employer
None of these update automatically. CRA: phone (single name) or mail/fax (both names). Banks: online or branch.

After provincial IDA name change requires a NEW passport at the full fee -- there is no amendment or reduced rate. Submit your marriage certificate or divorce order / resumption-of-surname certificate / court order.
Your submitted provincial ID must already show the new last name before IRCC will accept the application. Update your driver's licence and health card FIRST.
Fee as of 2026-03-31: $163.50 (10-yr adult) / $122.50 (5-yr adult). Passport fees index annually under the Service Fees Act. Verify the current fee on the IRCC website before applying.

CRA cannot update a name fully online. Changing a single name (first OR last) can be done by phone. Changing both names requires mail or fax with a vital-statistics name-change certificate or court order.
Recommended: update your SIN first, then call CRA to confirm (SIN may auto-notify CRA). Takes 4-6 weeks.
CRA does not share your name change with other departments. Update banks, employer, and other accounts separately.
