Transferring assets into a revocable trust is a relatively simple task. On real estate, bank accounts, and/or securities accounts, you provide a new deed moving the asset from your name into the trust name. But on retirement accounts, a married person should have his/her spouse be the primary beneficiary, so that they can roll over the assets without tax consequences. Your trust would be the secondary beneficiary. If not married, you should put those assets into your trust and have your trust disperse them accordingly.  Keep in mind, however, that there may be some tax issues you need to think through before making that move.
