            }
            else
            {
                <input type="checkbox" disabled="disabled" />
            }
            <input type="file" name=ficateFile />
        </div>
    </div>

A:

Without seeing your full code and css this is a tricky thing to answer however perhaps you could try this?
input[type=checkbox], input[type=file] {
    display: inline-block;
}

If that doesnt work you could allways split the checkbox and file upload into 2 columns eg 
<div class="form-group">
    <div class="col-md-2"></div> <!-- Label -->
    <div class="col-md-2"></div> <!-- Checkbox -->
    <div class="col-md-8"></div> <!-- File Upload -->
</div>
