Hey again @akki,
I'm unsure if I understand you correctly. Could you please clarify if you mean a class 10 school certificate?
In order to get married in Germany, you will need a number of documents. The core documents are a valid passport, a birth certificate and a certificate of no impediment. A school certificate would not be sufficient.
For more information on marriage, please have a look at our Wefugees Blog article on "How to Marry in Germany": https://wefugees.wordpress.com/2018/04/20/heiraten-in-deutschland-how-to-marry/
