Is it legal for you to find someone who already is homeschooling & pair up with them? If you have to work- can you pay another mother or dad to homeschool your kid? Is that legal?
Not sure of your State or local laws, but that might become a daycare and be regulated.
Laws vary from state to state but my simplistic answer is, if you and the other adult keep your mouths shut about the arrangement, who cares?
