Unsure about adding both parents on Common App?

<p>I feel a bit confused about adding both of my parents on Common App... I've lived with my mother for my entire life and have never met my dad. So when I fill in the information, I obviously just have my father's name; I don't even have an address. However, when I "Print Preview" the application, it doesn't have anything saying that my father is at an unknown address or anything and makes it seem like he lives with me. It just says that my parents are "Separated" in a box. I was wondering how I should go about that? Will the admissions officers get that he isn't apart of my life based on the fact that I don't have any information down for him, or am I going to need to type and attach a letter to my Common App explaining my family's situation?</p>

<p>I would suggest you add a brief explanation by attaching a document in the additional info section at the end.</p>
