        )

                    [admin_comment] => 
                    [approve_status] => approve
                    [other_gov_id] => 
                    [doc_no] => 1
                    [created_at] => 2020-04-04 12:39:12

Method 1

You can use laravel querying-relationship-absence

$users= User::doesntHave('user_documents')->get();

Method 2

Depending on how you have setup your relations, something like this should work:

User::doesntHave('documents')->get();
