Old checkbook transaction registers – how long are we supposed to keep these? How many of these do you have?

I went into the cabinet drawer to pull out old tax documents from 2011 and 2012 to shred. If you only need to keep these and their supporting records for 3 – 7 years (or indefinitely if you commit fraud hahaha – see this post) , then it seems like we can declutter these.  

I must have decluttered the registers from before we got married since the earliest I found was for 1984, the year of our marriage.  

64 registers gone!  plus another 23 random medical documents.  87 items gone today!

Now I’m off to shred them! I know, it’s overkill but . . .
