Adjusting Your Surname After Naturalization? Your Child's Age Decides Who Signs
After naturalization, you can adapt your name to the usual German naming form through a Namensangleichung, name adjustment declaration, under Article 47 of the Introductory Act to the Civil Code (EGBGB), and this can genuinely help with everyday integration. What actually happens to your child's surname if you make this declaration depends entirely on their exact age: children under 5 have their surname automatically changed alongside their parents, no separate action needed. Children between 5 and 7 need their own joining declaration submitted, but since they're still legally represented by their parents at this age, the parents submit it on the child's behalf as legal representatives. Between 7 and 14, the child can submit the declaration themselves with parental consent, though parents retain the option to submit it without the child's own involvement at this age. From 14 onward, the child has to give their own personal consent to the name declaration, this can no longer be decided purely by the parents. One detail worth knowing before you sign anything: a name adjustment declaration can only be submitted once, and it's irrevocable, so it's worth being certain of the decision for your whole family before filing it.
The Official Rule
Deciding to formally adjust your family’s surname to a more standard German form after naturalization feels like a personal, one-step decision, but what actually happens to each of your children depends specifically on their individual age, and it’s worth understanding this before filing anything.
After naturalization, you can adjust your name to the customary German form through a formal declaration. The Auswärtiges Amt’s official guidance confirms this process, a Namensangleichung, name adjustment, operates under Article 47 of the Introductory Act to the Civil Code (EGBGB), and it’s specifically designed to help facilitate everyday integration in Germany, it’s an available option, not a mandatory step of naturalization itself.
| Child's age | What happens |
|---|---|
| Under 5 | Surname changes automatically alongside parents, no separate action |
| 5 to 7 | Needs a joining declaration, but parents submit it as legal representatives |
| 7 to 14 | Can submit themselves with parental consent, or parents can submit without them |
| 14 and older | Must give their own personal consent, parents alone can't decide |
What happens to a child’s surname specifically depends on which of four age brackets they fall into. Serviceportal Düsseldorf’s official guidance on post-naturalization name changes confirms children younger than 5 have their surname automatically changed alongside their parents’ declaration, no separate joining action required for them specifically. Children between 5 and 7 need a joining declaration submitted on their behalf, but since they’re still fully legally represented by their parents at this age, the parents themselves submit this declaration as the child’s legal representatives.
The rules shift meaningfully once a child is old enough to have some say of their own. For children between 7 and 14, the Landkreis Schwäbisch Hall’s official guidance sheet on Namenserklärung confirms the child can submit the declaration themselves with parental consent, though parents retain the option to submit it without the child’s own direct involvement at this specific age, a genuine middle ground between the younger automatic-change bracket and full personal consent. From age 14 onward, this shifts entirely, the child must give their own personal consent to the name declaration, this can no longer be decided purely by the parents on the child’s behalf.
One detail is worth knowing clearly before submitting anything at all. A name adjustment declaration under Article 47 EGBGB can only be submitted once, and it is irrevocable. Given this permanence, and given how differently it plays out across your own children depending on their specific ages, it’s worth being genuinely certain of the decision for your whole family before filing.
What Real People Say
Families with children spanning multiple age brackets describe genuine surprise at how differently the process plays out for each child, several specifically mention initially assuming one single family-wide declaration would cover everyone identically, only to learn their older and younger children required meaningfully different levels of involvement and consent.
Families who filed their name adjustment declaration describe double-checking the irrevocable nature of the decision as something they wish they’d emphasized more before filing, several specifically recommend discussing the decision as a full family, including with children old enough to have an opinion, well before submitting anything, given there’s no way to reverse it afterward.
Step by Step
- Confirm each of your children’s exact current age before assuming a single process applies to all of them equally.
- For children under 5, expect the surname change to happen automatically alongside your own declaration, no extra step needed for them.
- For children 5 to 7, prepare to submit their joining declaration yourselves as their legal representatives.
- For children 7 to 14, decide together whether the child submits their own declaration (with your consent) or whether you submit it on their behalf.
- For children 14 and older, involve them directly, their own personal consent is legally required, not optional.
- Before filing anything, confirm your whole family is certain of the decision, it can only be submitted once and cannot be reversed afterward.

FAQ & Common Pitfalls
If we naturalize and adjust our surname, does our 3-year-old's name change automatically?
Yes, for children under 5, the surname change happens automatically alongside the parents' own declaration, there's no separate action or declaration needed specifically for a child this young. This is the simplest scenario of the age-based rules, the younger age bracket is handled without requiring any additional joining paperwork.
Our daughter is 6. Do we need her to sign anything, or can we just handle it as parents?
She technically needs her own joining declaration submitted, but at age 6, within the 5-to-7 bracket, you as her parents submit this on her behalf as her legal representatives, she doesn't need to personally sign or consent at this age. This is a meaningfully different rule than either the under-5 automatic change or the older-child consent requirements.
Our son is 12. Does he have to personally agree to the name change?
At 12, within the 7-to-14 bracket, he can submit the joining declaration himself with your consent as his parents, though you as parents also retain the option to submit it without his direct involvement at this specific age. This is a middle-ground bracket, more involvement is possible than for a younger child, but it's not yet mandatory the way it becomes at 14.
Can we change our minds later if we regret adjusting our name this way?
No, this is a genuinely important detail to know before filing anything, a name adjustment declaration under Article 47 EGBGB can only be submitted once, and it is irrevocable. It's worth being fully certain of this decision for your entire family, including how it affects each child's specific age bracket, before you submit the declaration.
