My husband & I went through a 'social study' back in 2003/2004. Basically you will have series of interviews with a master social worker who will 'study' you. She will observe you with your son & without. She will either interview your friends & family or have them write letters of recommendation on your behalf. The same social worker will go through the same process with your ex. In our case it took almost a year to complete. But... our case involved my husband's 3 school age children & both sides had blended families with 1/2 siblings & step siblings that were a part of the picture. They observed us as a family, interviewed us together, seperately & the same with all the kids. She interviewed teachers & reviewed school records & all of that. Medical records for all parties involved, back ground checks, you name it. It was a really invasive process for ANYONE! A lot of their focus will be determined by the claims of the other party (the ex). My husband's ex has extensive mental issues. She really put us through the ringer. She made every outlandish claim she could come up with and our 'studies' was invasive to the point that I literally wondered if they were going to ask us to bend over. If you know what I mean. After the interviews & observations are done, the social worker will write a report consisting of her findings from both sides that will include her recomendation to the court as to who should have primary custody of the child/children. In the end, the social worker & the judge ruled in our favor. We not only retained custody of their two sons (who my husband had been raising since the divorce when the kids were toddlers) but his daughter who had always resided with their mother also came to live with us. It was a nightmare to go through & I was glad when it was over (that's an understatement actually) but it was all about protecting our children & in the end was worth it! Looking back I am thankful that we were strong enough to endure it because it resulted in our family being brought together. All our kido's are teenagers now & are exceeding our expectations. They are ALL amazing! Did I totally scare you??? I really didn't mean to! Our case was extreme I am sure. Bottom line, just love your son & be honest! They will not take him from you unless they find VERY good cause. Good luck!
