Change Name After Divorce in South Australia

Changing your name after divorce is one of the more straightforward post-settlement tasks — but the process and cost depend on whether you're reverting to your birth name or choosing something entirely new.

In South Australia, name changes are handled by Consumer and Business Services (CBS SA), not the courts. The divorce order itself doesn't change your name — it gives you the legal basis to do so.

Option 1: Revert to Your Birth Name (Free)

If you took your spouse's surname when you married and want to revert to your birth name (maiden name), you don't need a formal name change application. Your divorce order, combined with your birth certificate, is sufficient proof for most institutions.

Cost: Free — no CBS SA application or fee required.

What you need:

• Your sealed divorce order (showing your married name)
• Your original birth certificate (showing your birth name)

Take both documents to each institution and request the name reversion. Most organisations process this within a few days to a few weeks.

Option 2: Formal Change of Name (For a Different Name)

If you want to change to a name that's neither your married name nor your birth name — or if you want an official change of name certificate for convenience — you apply through CBS SA.

Cost: $72 for a change of name certificate (2026 rates).

Process:

1. Complete the change of name application through the CBS SA website or in person
2. Provide proof of identity (birth certificate, passport, or citizenship certificate)
3. Pay the fee
4. CBS SA processes the application and issues a Change of Name Certificate
5. Use the certificate to update your records across all institutions

The certificate is a legal document that provides a single proof of your name change, which can be simpler than carrying around a divorce order and birth certificate to every appointment.

Where to Update Your Name

Once you have your documentation (divorce order + birth certificate, or change of name certificate), update your records in this order:

Priority 1 — Identity documents:

• SA driver's licence (Service SA — in person, free with supporting documents)
• Australian passport (Department of Foreign Affairs and Trade)
• Medicare card (Services Australia / MyGov)

Priority 2 — Financial institutions:

• Banks and credit unions (all accounts, credit cards, loans)
• Superannuation funds
• Insurance policies (home, car, health, life)
• ATO records (via MyGov)

Priority 3 — Property and government records:

• Land title (Land Services SA — if you retained property in the settlement)
• Vehicle registration (Service SA)
• Electoral roll (AEC — mandatory to update within 21 days)
• Centrelink (if applicable)

Priority 4 — Everything else:

• Employer / payroll
• Utility accounts
• Subscriptions and memberships
• School and childcare records

Name Change for Children

Changing a child's surname after divorce is a separate and more complex process. It requires the consent of both parents, or a court order if consent can't be obtained. This is governed by the Births, Deaths and Marriages Registration Act 1996 (SA) and requires an application through CBS SA.

A parent cannot unilaterally change a child's surname. If your former spouse objects, you'd need to apply to the FCFCOA for a specific issues order — and the court will prioritise the child's best interests, not the parents' preferences.

Timing the Name Change

There's no legal deadline for changing your name after divorce — you can do it immediately or years later. However, doing it sooner simplifies things. The longer you wait, the more documents accumulate under your married name, and the more institutions you'll need to notify.

Many people complete the name change as part of their post-settlement administrative tasks. The South Australia Divorce Financial Split Guide includes a post-settlement checklist that sequences the name change alongside property transfers, account closures, and other administrative steps that need to happen after your Consent Orders are sealed.
