CCR's in older subdivisions

[Account Closed]

Many of the listings I look at have a notation beside
RESTRICTIONS: yes

I'm looking in an area of older HOA's, 30 years and more, old. I have not read any of their ccr's, and though I've asked my agent about them, all she has said, is, yes, these are over 30 years old, so the HOA is gone. That is not necessaarily so. My own HOA ccr's state sopmething like:
expiration states "...for a period of thirty (30) years from the date these covenants are recorded, after which time said covenants shall automatically be extended for successive periods of ten (10) years unless and until an instrument signed by the then record owners of leasehold equities...has been recorded,by which said covenants, in whole or in part, are amended or revoked."

If the ccr's are NOT revoked, they are probably still in effect.
Where would one go to find out if the covenants, in whole or in part, were amended or revoked? Since HOA's are corporations, would it be the county recorders office, a state agency, or someplace else?
