Thank-you to everyone who responded to my issue of custody and my right to continue homeschooling.
I don't fault the HSLDA for not getting involved. Like the rep told me, the real issue is custody and the tool to get that away from me is homeschooling. I checked the Rutherford Institute and they have the same policy.
There are reasons why I have always had full / sole legal custody of DS. His bio dad has very limited, ordered by the courts, contact with him. I'm starting to feel that this is something he doing's to get even with me for some perceived aggreviance. It's still very frightening for me because if I get in front of a judge that is not homeschool friendly ...
If I can brag on my son for a wee bit, in public school he was doing awful. He had a .93 GPA when I finally pulled him out. He just took the IOWA state testing and except for 1 subject which we hadn't covered yet, he scored 13+ in everything. He was in 10th grade at the time of the testing. The subject we didn't cover yet, because he had it in public school, was Algebra, and he scored a 9.6. I plan to teach that to him this year. Well, planned I should say.
And I don't mean that "na-na, my kids better than yours". Not at all!! I just use it as proof, proof to me at least, that he is thriving in homeschool. Bio dad wants him placed in a school that ranks #162 out of #308. That's the bottom 50%. How can that ever be a good idea? The public school in my community ranks #59 out of #308. Huge difference.
DS has never been social. He always complained that other kids picked on him, talked bad about him and he was bullied.

I've got documentation from the school on that.
He's a little more social now but it's a long process. He loves our homeschool co-op group and the other kids are always inviting him over.
Sorry to be so long winded. I wanted to answer some questions / update on what I could. It's a very difficult time for me but I know in my heart that homeschooling is best for him.
