These days, most of us in "the 99%" who have any estate at all have most or all of it invested or saved with a financial institution. All those institutions have a process where you can designate a list of beneficiaries who will receive the funds immediately upon your death -- meaning that the funds bypass probate and are rapidly accessible to the beneficiaries you name.
I suggest that you set a specific date each year that is meaningful for you -- maybe New Years, or your birthday, or your anniversary, or your retirement date, or some other very memorable day that rolls around every year and that will always remind you to spend an hour or two reviewing your estate plans and these beneficiary lists.
And note that you need to actually confirm what the financial institutions have -- it's not enough to just look at your list of who you think they have. With the internet, confirming your beneficiary designations is usually just a matter of logging onto the company website and calling up your beneficiary list. Do this for each bank or investment institution where you have funds.
Next, make sure your will or trust or durable power of attorney are still compatible with your wishes, and go over your advanced medical directive in case your wishes have changed there.
This annual estate planning review is one of the best ways to ensure that the estate you leave behind actually winds up getting where you want it to go with a minimum of fuss and expense.
