If you still have something from American Savings Bank, F.S.B.
A lien that was never released
American Savings Bank, F.S.B. was closed in a federal resolution on Nov 1, 1991. The FDIC's lien-release page covers failed banks and savings and loans placed in FDIC receivership; it does not say how releases work for resolutions this old.
Call FDIC Resolution Inquiries at 888-206-4662 (8am–4pm Central, weekdays) and ask whether the FDIC holds this institution's receivership. Ask BMO Bank National Association as well: the chain above leads there. The FDIC's own instructions are at FDIC, Obtaining a Lien Release.
An old account, passbook or CD
When a healthy bank assumes a failed bank's deposits, insured depositors become its customers right away (here, Home Federal Savings and Loan Association of Ada). Start with BMO Bank National Association, and ask them to search under the name American Savings Bank, F.S.B..
This failure is older than the current federal rule on unclaimed deposits (mid-1993), so different rules apply. Search FDIC unclaimed funds search, search the unclaimed-property program of the state of the owner's last known address on the bank's records, and ask FDIC Resolution Inquiries at 888-206-4662 what applies to this institution.
A safe deposit box
The FDIC says that when a healthy bank assumes a failed bank's deposits, the branches usually reopen the next business day with box access. Today, ask BMO Bank National Association. A box abandoned for years may have been turned over to the state's unclaimed-property program.
Box contents are not covered by FDIC insurance.
Not sure this is your bank?
Many banks shared a name. Match the city and the years above against your paperwork, or search again with the town.
Credit unions were never FDIC-insured and are not in this record; the NCUA credit union lookup covers those. Banks that closed before about 1970 are not in the FDIC's list either.
One caution: banks also sell single branches. If the office you used was sold to a different bank along the way, the account went with the branch, not with this chain.
