If deed restrictions are on the original deed but do not show up on a later deed of a new owner can a Homeowners Association enforce the original deed restrictions in Arkansas?

Yes. It is the responsibility of the buyer to have a professional title examination performed to disclose deed restrictions that appear in the chain of title but do not appear in the present owner's deed. From articles I have seen it is a common problem in Arkansas that restrictions are not carefully carried forward in deeds. That error does not make them unenforceable. If the restrictions have not expired by a statute of limitations they are still in effect.
