And also, keep bank statements and paperwork related to them.
When my aunt passed away, there were problems with her estate, because she had bank accounts at banks which had been bought out by other larger banks, and bond coupons to cash in, which were somehow involved with banks which no longer existed.
I wasn’t privy to all the details, but apparently she had some bonds, had failed to cash in the interest due from the coupons, and the cashing in process involved a correspondent bank, which had been bought by another bank, so the bank didn’t exist any longer.
If a bank merges into another bank, or is bought by another bank, the transition should be seamless. But if enough years go by, and there’s no paperwork on it, and you have to try to prove to someone at the bank that this account existed and was absorbed from another bank, you will have a tough time getting your money.
Keep HARD copies of the statements. I will never willfully agree to all electronic statements.
On the subject of money security, anyone having fallout problems from the equifax mess? I started to get lifelock until I found out they partner with equifax. That relationship makes lifelock a non-starter to me.
