what is the cost range for a simple will and healthcare power of attorney for a married couple in Illinois?

Dear Illinois, The prices vary by attorney and locale within the state....think lots of experience vs. less experience...think Harvard vs. State......think high rent vs low rent districts....and all of those factors are justifiable to take into account when setting fees.   Typically however, you may pay anywhere from a flat fee of $350.00 to $650.00 for a simple will and $100.00 to $175.00 for a Power of Attorney OR some attorneys charge you for everything by their "rack" rate (hourly).  It really varies by attorney.  I'd recommend you calling around to a few firms to see what's offered and then you'll have a few prices and can determine an average cost....or at least what you're willing to pay.  Best of wishes with everything.
