I have never had legal problems while homeschooling, because I live in a small school district.Often, I am the only homeschooling mom in the district. One year, they never responded to my letter of intent to homeschool and apologized at year's end.
The neighboring district, however is much bigger and bureaucratic, they unjustly returned all the mothers' Individual Home Instruction Plans, and Home School Legal Defense had to be called in.
