You can't get credit for college marriage. Although the marriage certificate is a national certificate, because it has nothing to do with studies and does not belong to a certain category of skills, the marriage certificate, including the divorce certificate, is not included in the scope of certificates that can be added credits in the university.
In 2005, the "Regulations on the Management of ordinary college students" was issued to cancel the special provisions of "students who get married without dropping out of school during the study period will be treated as dropping out of school", which means that China began to allow college students in school to get married.
However, allowing does not mean advocating, but it is no longer mandatory opposition and relevant punishment measures. College students still take their studies as the main task, and most college students lack strong material and spiritual support in taking the responsibility of marriage and family, and it is not recommended to reward credits for such behavior.
Marriage certificate (including divorce certificate) although belongs to the national certificate, but considering its nature has nothing to do with studies and skills, this is also one of the main reasons why major colleges and universities in China have not incorporated marriage certificate (divorce certificate) into the credit policy.
