as for your question:
- the time it might take depends on the authorities in Kenya, however you could get a certification by the embassy of Kenya in Germany, that proves that your divorce documents are not fake.
- as for the birth certificate, if you have a Auszug aus dem Geburtenregister from the Standesamt, almost all German authorities accept it on behalf of the birth certificate.
