My husband changed the bank account for his direct deposit on his mypay on January 15th. Does this mean his next pay check will be deposited into that account or will it remain going into the old bank account for a few more paychecks? I don't see how 2 weeks isn't enough time to process his new information but just wondering. 

Good rule of thumb that Finance recommends: if the Direct Deposit action isn't processed by the 10th of the month, it's likely not going to go through to the new account yet. Not saying it won't--but it's not likely if it was on the 15th.

Most important thing is to NOT close the old account until it clears in the new account. Know a few people this happened to; it SUCKS to get fixed and you will not be able to get the money right away. 

Better safe than sorry. LES's are up right now, so you could look at it and see what bank the comments say it's going to. Unless his new account is at the same bank, then it wont be much help.
