Expired Covenants

non profit Rolling Oaks Association, INC. in Checotah, OK, the dues are voluntary, the CCR's expired in 2012 but the association is still using some of the amended CCR's since 2010. We have one 6 acre empty lot(fraternal recreation area) that is maintained by the association and dues are $50-$150 a year depending on size of the owners lot. Are we allowed to rewrite and amend the expired CCR's. The Rolling Oaks Association also pays the yearly taxes $60 out of the dues for the 6 acre's. Our CCR's are simple and to the point to keep our property values up.
Also, the ownership of the 6 acre lot ownership was turned over to the property's that back up to the acreage. We are responsible for liability insurance not the association, but we have promised the fraternal recreation area to the association for mowing and everyone's enjoyment. This is our only common area. The 6 acre(fraternal recreation area) can not be sold or developed for anything and we are not going to deed it to the association.
Should we hire an attorney?? I am the President and faithfully just trying to do the right thing. Please, I will appreciate all comments and reply's.
Sharon Bass, President Rolling Oaks Association.

Tim,
Thank You for your input. I had a gut feeling an attorney may be needed. This neighborhood association covenants were written in 1962 and had an expiration date to be null and void after 50 years which was 2012. This neighborhood is on a lake and keeping the property values up is our main concern.
