Is there a special form to fill for applying for the 7 years concessions

hi,
I'm overstayer in uk, my son is seventeen and is a british citizen who hold a british pasport, I'm not with his mother anymore and we were never married I was wondering if there is a way that i can regularise my status via him. His birth certificate shows that I'm his father.
