You can consult first with the clerk's office, probate division to see if they have an expedited method to deal with small estates. If they have no suggestions, Seek an attorney to advise you of the easiest way to deal with your check.
I agree with Mr. Shelley. Consult the circuit court to determine if you can accomplish this without opening the estate. My presumption is that you could use a small estate affidavit, similar to the one you stated, to provide evidence to the bank that you are the beneficiary, or receiving such money on behalf of the beneficiaries, of the estate. I do not think you will need an attorney, unless you encounter a problem. If you do encounter a problem, then a lawyer should be able to achieve your goal in relatively little time and with relatively little effort.
