Retrofit will parse all attributes that you specified in your model. If some attribute in your JSON does not exist Retrofit will set NULL as the value of that attribute.

Knowing this feature, the only thing that you need to do is something like:

if(myObject.getReviewerDetails() == null)  
 // do something

Happy code!

You can check key exist or not using jsonObject.has like following way,

      JSONObject jsonObject=new JSONObject();
        if(jsonObject.has("reviewer_details")){
          //do process with data
        }
