, do you both have accounts at the same banking/investing institutions?
401ks, by nature, are at whatever institution the employer chose to be the custodians of their 401k plans. Semi-amusingly, my last two employers went through division spin-offs and/or being acquired, and I ended up with SIX 401k plans out of two employers - but all held at an institution that I'll call Alpha Investments, just for this thread.
I have a regular and a Roth IRA, both held at "Beta" Investments. These contain a mix of rollover and direct contributions over the years.
She has reg & Roth IRA at the same Beta Investments as I do.
IRA = Individual Retirement Account, focus on Individual. Only one person can have investment decision power on an IRA...except that we share everything, including email passwords, our list of web properties we're members of, etc, and have an agreement that we won't change the other's accounts - but we like to check balances.
Our accounts at Beta have but one username and password, so we can both see them.
Regular banking: Local credit union for checking, savings, and "long term savings", an account with higher interest and min. balance.
Business banking: since my biz is still small, I'm using personal accounts, but at a different smaller local bank than our household stuff. She shows no interest in having any access to the biz accounts.
Would you propose to have it different?
