Legal Description Abbreviations Potential Issue Chicago Cook Co

[Tony Rodriguez]

Hello all, I'm in the process on closing on a property located in Chicago and the title commitment has the legal description of the property as ... PRINCIPAL MERIDIAN, IN COOK CO ILLINOIS. but the current recorded deed has the description as ... PRINCIPAL MERIDIAN, IN COOK COUNTY ILLINOIS.

So the word COUNTY has been abbreviated to CO in the title commitment I'm supposed to sign, my lawyer says it should be OK but I'm not so sure, I have yet to find a deed in cook county that abbreviates the word cook. I'm I being too picky or can this be a potential issue when I sell the house?
