Niederlassungserlaubnis: Married or Separated Status with Pending Divorce?

Hello,

I am an Indian national applying for Niederlassungserlaubnis with Oberhavel. I have an unlimited employment contract, B1 German certificate, and all required documents.

My situation:

• Wife: Living permanently in India
• Status: Legally married but divorce case is pending in Indian court
• We live in separate countries (no plans for her to come to Germany)

Important clarification: This is about the pending divorce case only. There is no maintenance/spousal support involved, no criminal issues, or other complications. Only the divorce case status.

My question:

When I fill the Niederlassungserlaubnis form, should I mark my family status as:

1. "Verheiratet" (Married) - since divorce is not finalized?
2. "Getrennt Lebend" (Separated) - since we live in different countries?

What I need to know:

• Which status is correct for my situation?
• What documents do I need to provide as proof of status?
• Does the pending divorce affect my application?

Additional Context:
This is purely about my individual settlement permit application.

Thank you for advice.
