If it is yes and your questions;
1-In Turkish legal system doesn't want to police report on divorce cases.
2- We dont know how you can realize "search his background". It is related your country rule.
3-"a virtual separation period of 1 year" means that ; he abondoned his family.
And in Turkey when a child born in marriage period; parties are parents of this child.
If he isn't his child; this situation must be proved.
