Client consulted Lawyer about handling the sale of Client's building, and asked Lawyer what her legal fee would be. Lawyer replied that her usual charge was $100 per hour, and estimated that the legal work on behalf of Client would cost about $5,000 at that rate. Client said, "Okay; let's proceed with it," and Lawyer timely and successfully completed the work. Because of unexpected title problems, Lawyer reasonably spent 75 hours on the Lawyer reasonably spent 75 hours on the matter and shortly thereafter mailed Client a bill for $7,500, with a letter itemizing the work performed and time spent. Client responded by a letter expressing his good-faith belief that Lawyer had agreed to a total fee of no more than $5,000. Client enclosed a check in the amount of $5,000 payable to Lawyer and conspicuously marked, "Payment in full for legal services in connection with the sale of Client's building." Despite reading the "Payment in full..." language, Lawyer, without any notation of protest or reservation of rights, endorsed and deposited the check to her bank account. The check was duly paid by Client's bank. A few days later, Lawyer unsuccessfully demanded payment from Client of the $2,500 difference between the amount of her bill and the check, and now sues Client for that difference. What, if anything, can Lawyer recover from Client? 
Nothing, because the risk of unexpected title problems in a real-property transaction is properly allocable to the seller's attorney and thus to Lawyer in seller's attorney and thus to Lawyer in this case.  Nothing, because the amount of Lawyer's fee was disputed in good faith by Client, and Lawyer impliedly agreed to an accord and satisfaction.  $2,500, because Client agreed to an hourly rate for as many hours as the work reasonably required, and the sum of $5,000 was merely an estimate.  The reasonable value of Lawyer's services in excess of $5,000, if any, because there was no specific agreement on the total amount of Lawyer's fee.
