Is my dad not my real dad?????

okay so i had to make a copy of my birth certificate for something, and my parents were on vacation so i went through our files to find it. curiosity got the best of me when i saw an envelope from the court so i opened it and they were paternity papers. my mom was the petitioner and my stepdad the respondent. my dad was only mentioned once in the papers as her having been married to him. what i dont understand was the DNA test papers. the people tested were me, my mom and my stepdad. and it said something like "the respondent (his name) should not be excluded as the father of the child blah blah blah there is a 99.85% chance of paternity. my question is WTF. and now that i think back to it i remember when i was 7 (the year the papers were dated) getting swabbed my mouth swabbed and recently i asked my parents what it was cause i was thinking about it and they were like "we dont remember, probably something for insurance. WTF?????????? what conclusion should be drawn from this?

the thing is im still really close to who i thought was my real dad, but i dont know what to think now

Your mom and stepdad are your biological parents.

You should draw the conclusion that your step-father is, in fact, your real father. Sound pretty clear to me. So, your parents are your parents, doesn't sound like anything to be all worked up about. If it bothers you, talk to them about it.

looks like your mother cheated on your "dad" with the person who is now your "stepdad". Your stepdad is your biological father.

Start. Running.

Sounds like you step dad could be your dad. I wonder is your supposed real dad paying child support?

Legally, if your mother was married to someone when she was pregnant with you and gave birth to you then in the eyes of the law, that person is your father unless that person filed legal paperwork challenging the paternity and terminating the legal rights.

the language you quote "the respondent should not be excluded as the father of the child" means the respondent is your biological father.

However, biology is not the only thing that makes a father. If your Dad supports you, loves you, and acts like a father too you, and he is your father in your heart and in his heart, then he is your father and biology doesn't change that.
