Sadly enough even checks on closed accounts can be "cashed" by other banks who don't know that the account is closed. We have no access to those systems.
The procedure at BofA is standard, and pretty long standing (It was the same when I was there six years ago). The reason being that a cashiers check can be deposited, or cashed at ANY bank. We aren't allowed to put a hold on it. So, while this is an unlikely situation, what could happen is that the check could get lost and end up here in Alaska. I could take it for deposit, not put a hold on it (because I can't) and the person depositing it could take all the cash out the next day and I couldn't stop them. Then 5 or 10 days later I'd find out the check was actually stollen from you, and be out the entire amount if my depositer took off (and they often do)
They do not typically pay interest, but your situation (return receipt that was signed on a trust check) is a bit different than the norm. I personally would call the officer working on the trust and ask for the interest, as well as what the status of that receipt was (what address did it go to...who signed etc.) If the trust is of any decent size they will want to "make you happy" and might offer up the interest on a similarly termed certificate of deposit. It won't be much, but I'm sure for you...it's the principal of the thing right?
Do not talk to a branch about this. Go right to the top (the Trust area). Even a low level person in that department has more ability to handle your issues quickly and easily than a person in the branch system who has no involvement, and can't see the trust system on line.
Tell them Dawnie sent you...and I'm still waiting for them to rescue me from Alaska where they sent me in 1998
