The process of acquiring German citizenship as a spouse requires you to prepare carefully and follow specific steps. The following diagram shows how you need to proceed and what to expect.
Separation before the end of the proceedings: What now?
If there is a separation during the proceedings without the marriage being divorced, this can still be considered a breakdown of the marital relationship. In such cases, the basis for simplified Naturalization in accordance with § 9 StAG no longer applies.
It is therefore advisable to inform the naturalization authority about the separation at an early stage inorder to avoid possible legal consequences. However, you still have the option of applying for Naturalization in accordance with the general provisions of § 10 StAG.
However, a change of residence permit is often necessary in the event of separation or divorce. You must therefore check again whether your new Residence permit is eligible for Naturalization . Naturalization is possible with the following titles:
- Residence for the purpose of gainful employment, e.g.: § 18a, § 18b, § 18g and § 21 AufenthG.
- Residence on humanitarian grounds, e.g.: § 25 a and § 25b AufenthG.
- Residence for family reasons, e.g.: § Section 28 (1) sentence 1 no. 3, Section 31, Section 36 and Section 9 AufenthG.
