You can basically use any institution you want. I have an all Vanguard portfolio so I opened mine with Vanguard. I believe some institutions charge fees if you buy another institution’s funds through them (again, not something I’ve had to deal with). The bogleheads have documented how to build a three fund portfolio with funds from various institutions. 34 minutes ago, NYAdmin said: am wondering about your statement that the Three Fund Index takes hours per year to manage. I think I'd go with 50% Total Stock, 25% Total International and 25% Bond. What is there to manage? Can't I just declare my funds, then let the sit? So the reason it takes a few hours per year to manage is because you need to keep those funds in the right proportion to each other. When your portfolio is small this means putting new money into the funds that are “low” and when your portfolio is large it means occasionally selling what you have too much or to buy what you have too little of. If you wanted to literally do nothing then a target date fund or a fixed allocation fund like Vanguard’s life strategy fund will handle that for you. 39 minutes ago, NYAdmin said: Also, it looks like my husband also has a percentage money from his 401K invested in Vanguard's Total Bond and Total International as well as a bunch of other Vanguard Funds. Is it not wise to both have money going into the same fund? Please read my blog post on investing in a marriage that hopefully will last, but may not. I wrote that before I got divorced and I’m happy it is something we considered. To answer your question directly, owning a fund in multiple accounts is fine, owning a fund in a single account is fine. That isn’t what matters. Let’s assume you won’t get divorced. You and your husband should decide on an asset allocation that works best for you two. You should view your entire portfolio as the summation of each account and buy funds in each account based on how cheap it is. Suppose everything in your husband’s 401k is expensive except bonds, you’d want to keep your bonds there (as much as possible), which would mean your other accounts would have to be more stock heavy in order to reach your overall desired asset allocation. ...if your husband has a bunch of funds that either means he is betting on specific sectors/asset classes, which I wouldn’t do, or his account is needlessly complicated, which I also wouldn’t do. It isn’t a huge sin, but it is something to consider.
