If you're using standard plugin, such code should be supported:

$(document).ready(function() {
    $("#myForm").validate({ 
        submitHandler: function(form) {
            SomeFuncHere();
        }
    });
})

The code in submitHandler should be called after successful validation.

Edit: based on your code, try this instead:

$("#myform").validate({ 
    submitHandler: function(form) {
        var cboxes = ($('input:checkbox:checked').filter(":checked").length);
        var nboxes = ($(":checkbox:not(:checked)").length);
        var flag = false;
        if ((cboxes > 0) && (nboxes > 0)) {
            flag = confirm('You have Checked only few locations among the List. \n Are you sure, you do not want to Prescribe from the other locations? ');
        } else if (cboxes == 0) {
            alert('Please select atleast One Address \n Where you would prefer to prescribe from.');
        }
        else {
            flag = true;
        }
        return flag;
    }
});
