Married to a German in Berlin: § 9 StAG Shares LEA's One Portal, Not a Guaranteed Spot in Line

The Official Rule

Being married to a German citizen barely touches most of what naturalization asks of you, what it actually shortens is the calendar. § 9 StAG lets a spouse or registered life partner of a German citizen apply after just three years of ordinary, lawful residence, two years short of the general five-year minimum, on the condition that the marriage or partnership itself has already existed for two full years. These aren’t the same countdown, they run on separate tracks. Somebody who arrived in Berlin, married a German citizen twelve months later, and has now logged three years in the country and two years married satisfies both figures simultaneously, since the two periods are free to overlap rather than needing to happen back to back.

A detail worth checking before anything else: the German partner has to have carried German citizenship across that whole stretch, this route rewards marrying someone already German, not someone who picked up citizenship mid-relationship. Beyond that narrower residence math, every other piece of a standard Berlin filing under § 10 StAG, already laid out in depth in this site’s main Berlin naturalization guide, still has to be satisfied: B1 German, income that doesn’t lean on certain public benefits, a settled identity question, and, for most applicants, a passed Einbürgerungstest.

A discretionary shortening beyond the 3 years exists too, for reasons of public interest, once a marriage or partnership has run for at least 3 years, but this is a case-by-case exception rather than something to plan around, and worth raising directly with LEA if you genuinely think it applies rather than assuming it automatically does.

What Berlin Hasn’t Published

Compare two cities and the gap becomes obvious. Hamburg’s own parliament, the Bürgerschaft, holds a written answer stating an exact figure: 97 people naturalized under § 9 StAG in Hamburg in a defined window in 2025, out of a known total. Berlin has never produced the equivalent number in anything found while researching this page, and the reason isn’t that the underlying data doesn’t exist.

The Amt für Statistik Berlin-Brandenburg, the joint state statistics office, describes its own naturalization data collection this way: “Erhoben wird die Struktur der eingebürgerten Bevölkerung hinsichtlich demografischer Merkmale, Aufenthaltsdauer, bisheriger Staatsangehörigkeit, Rechtsgrundlage der Einbürgerung und Beibehalt der bisherigen Staatsangehörigkeit,” the legal basis of each naturalization, alongside demographic traits, residence duration, and prior nationality, is explicitly one of the fields collected. What the office’s public tables actually publish, though, is limited to yearly totals, age groups, and breakdowns by prior nationality, not by StAG section.

That gap shows up in the Senate’s own written answers to the Abgeordnetenhaus too. A February 2025 written question (Drucksache 19/21757) asked, among other things, how the 21,802 people naturalized in Berlin in 2024 broke down by district, and the Senate’s answer was direct: no such breakdown exists to hand over. A more recent answer, Drucksache 19/26331 from June 2026, gives the city’s overall naturalization totals in detail, already covered in this site’s main Berlin naturalization guide, but again reports them as aggregate figures, not split by legal basis. Nothing found while researching this page suggests Berlin’s Senate has ever been asked, in writing, exactly how many people used § 9 specifically, the way Hamburg’s Bürgerschaft has been.

None of this means the spousal path is rare in Berlin, only that the city hasn’t chosen, or been asked, to say the number out loud. If a future written question changes that, this page will reflect it.

One Portal, Solo Filing

Service Berlin’s own Einbürgerung page lists “Staatsangehörigkeitsgesetz (StAG) §§ 8, 9, 10” together as the legal bases behind a single listed service, and offers exactly one route in: “Jetzt online erledigen,” the same Online-Antrag with its preceding Quick-Check that every naturalization applicant in the city uses, regardless of whether they qualify under § 8, § 9, or § 10. There’s no dedicated § 9 form to hunt for, and no separate spousal portal sitting alongside the standard one.

What the same page does spell out clearly is who files alone versus who can be folded into someone else’s application. As this site’s guide to how LEA handles a child’s co-naturalization covers in detail, a child under 16 can be requested inside a parent’s own Online-Antrag. Service Berlin’s page draws a firm line past that: “Ehegatten, Lebenspartner und Kinder ab 16 Jahren müssen einen eigenen Antrag stellen,” spouses, registered partners, and children aged 16 or older each have to submit their own independent application. A § 9 applicant sits squarely in that second group. You’re an adult naturalizing on your own legal basis, not a dependent riding along on your German spouse’s status, and LEA’s system treats you accordingly: your own Online-Antrag, your own Quick-Check, your own €255 fee, through the identical portal every other adult applicant in Berlin already uses. What differs from a standard § 10 filing is simply which supporting documents you attach, your marriage or partnership certificate and proof your spouse held German citizenship throughout, not which system processes it.

A Queue That Isn’t Strictly First-Come

Here’s where Berlin’s own record diverges from Hamburg’s in a way worth sitting with before you file. Hamburg’s Bürgerschaft has stated plainly that its Amt für Migration works through every application in strict chronological order by filing date, whatever legal basis it’s filed under. Berlin’s Senate, asked a related but distinct question, gave an answer that runs the other way.

In a June 2026 written answer (Drucksache 19/26331), a member of the Abgeordnetenhaus asked directly whether LEA had decided to prioritize its oldest backlog cases. The Senate’s response ruled out a pure first-in-line system entirely, for either direction: “Die Bearbeitung erfolgt nicht allein nach dem Eingangsdatum des Antrages, da dann neue und bereits entscheidungsreife Anträge zurückgestellt werden müssten,” processing does not follow the filing date alone, because doing so would force newer applications that are already ready for a decision to be set aside. The Senate went on to describe the actual practice: LEA works older and newer cases in parallel, treating a file’s Entscheidungsreife, how ready it genuinely is for a decision, as a factor alongside how long it’s been sitting, specifically because that combination has proven more effective at keeping overall processing moving as naturalization volume has climbed.

What this means in practice is genuinely more uncertain in Berlin than in Hamburg, not less. Hamburg’s system gives you a clear, if unwelcome, answer: a shorter residence requirement buys no shortcut, full stop. Berlin’s system leaves the door structurally open for a quickly-completed, well-documented § 9 file to reach decision-readiness sooner than an older, more complicated standard case and get worked in parallel with it, but nothing in the public record confirms that happens for § 9 cases specifically, or that LEA treats them any differently from a standard filing once they’re both sitting in the queue. Plan around Berlin’s own honest range, a year or longer, sometimes just a few months, rather than assuming either a shortcut or a guaranteed place in strict order.

What Happens to a Family, and What Happens if the Marriage Doesn’t Last

Two federal features ride along with a § 9 applicant no matter which city’s office is handling the file. A couple’s minor child can naturalize at the same time without clocking up any residence of their own, and inside Berlin that runs through the exact under-16 mechanics this site’s guide to LEA’s child co-naturalization already walks through, folded into the same Online-Antrag, the same signed consent template when custody is shared, and the same 51 EUR add-on per child. Filing under § 9 instead of the standard route changes nothing about how that part works.

There’s also a narrow window if the marriage itself doesn’t survive. File within a year of your German spouse’s death, or within a year of a divorce becoming final, and you’re still raising a minor child from that marriage who already holds German citizenship, § 9 remains open rather than bouncing you back to the ordinary five-year requirement. Nothing turned up in Berlin’s own published guidance addressing this scenario specifically, which suggests LEA simply applies the federal wording as written, the same way any German office would. Confirm your own deadline directly with LEA if this situation applies to you rather than assuming the clock is more forgiving than it is.

Documents to Have Ready

• Records establishing an uninterrupted three-year stretch of lawful residence in Germany.
• Your marriage or partnership certificate, dated to show the relationship reached its two-year mark.
• Something confirming your spouse’s German citizenship stretches across that whole window, not merely the present day.
• The rest of the ordinary § 10 file: a B1 certificate, evidence your income holds up on its own, an Einbürgerungstest pass (or paperwork excusing you from it), and standard ID documents.
• If it applies: a finalized divorce decree or a late spouse’s death certificate, apostilled and translated if either was issued outside Germany.
• A completed Online-Antrag under your own name through service.berlin.de, kept separate from any application your spouse might file.
• The €255 fee, settled by card or PayPal when you submit.

Step by Step

Compliance Note

This page walks through the § 9 StAG spousal route and how Berlin’s Landesamt für Einwanderung handles it, reflecting information gathered in mid-2026. Nothing here substitutes for legal counsel. Individual circumstances, particularly around death, divorce, or unusual documentation, can shift how a case plays out, and Berlin has published comparatively little of its own data on this specific pathway. Where your situation isn’t straightforward, reach LEA through its official channels, or a lawyer working in Staatsangehörigkeitsrecht, before treating anything above as the final word.
