To obtain a tax ID # for the estate, you need to complete the
SS-4 form(click link and print).
Once you have the Tax ID # (usually you can call IRS, they will give you one over the phone, then you can mail the form to them), you can open an account in the "Estate of John Doe". Once the account is established, you can disburse the funds in accordance with the will or if there is no will, as state law dictates. The account may come in handy, as other checks payable to the estate may come in.
You did not say what state you are from, perhaps if you post it, then another person from that state can respond with state-pertinent materal for you.
Good luck.
