The breach was real. The payout was zero. One missing link decided it
A real estate attorney took his own brother to court, proved the brother broke faith – and still walked away with nothing.
That is the takeaway from an Illinois appellate ruling handed down June 2, 2026, and it is worth the attention of anyone who has ever shaken hands on a development deal with a partner they trusted.
Go back to 2004. William Graft, a real estate attorney, heard that 110 acres of Barrington farmland were available. He brought in his brother Michael, a home builder, and together they set out to build a gated subdivision called Tallgrass. The brothers co-owned two companies for the job – Honeybee Land Investments to finance and hold title to the land, and Exclusive Land Development to fund the infrastructure. They bought the acreage and split it into 71 lots.
The money came from Harris Bank. Exclusive borrowed $8,030,000 for infrastructure; Honeybee borrowed $7,730,000. Lots went on the market in 2006 at prices from $450,000 to $630,000, and every dollar of those early sales went toward paying down the Exclusive loan.
Then the housing market fell apart. By October 2009, the brothers had sold only 7 of the 71 lots.
What turned a bad market into a lawsuit was what Michael did next. He carried a separate $4 million Harris loan for his own company, Builder. The court found Michael never told William when that loan defaulted, and kept William out of his talks with the bank. Then, in September 2012, Michael signed what the court called a secret agreement with Harris: he would work to convince William to enter a consent foreclosure on Tallgrass, and in return Harris would forgive $6,900,000 of his own debt.
William sued his brother for breach of fiduciary duty – the good-faith obligation business partners owe one another.
On that point, he won. The trial court found Michael breached his duties three ways: hiding the Builder default, entering the secret agreement, and selling a lot for less than the price the brothers had agreed on.
But a breach alone does not win a case. William still had to prove the breach caused his losses, and that is where it fell apart. His argument was that, without Michael's betrayal, the brothers could have found a bridge lender in 2012, refinanced, and come out ahead. He leaned on three experts: an appraiser who valued the unsold lots at nearly $29 million, and a financing consultant whose projections put the lost profit somewhere between $5.8 million and $13.8 million, with a third expert testifying that a hard-money lender would have refinanced the project.
The court rejected the chain. The appraisal used the brothers' 2006 peak-market values, cited no comparable sales in the county where Tallgrass sat, and assumed the lots were clear of the foreclosure that actually clouded them. Because the profit projections were built on that appraisal, they fell with it. And no one showed Harris would have dealt – the bank had already turned down a $6,450,000 buyout offer twice.
The conclusion: Michael's breaches were real, but they were not the proximate cause – the direct, legally responsible cause – of the loss. The appellate court affirmed. William's separate attempt to revive an amended complaint was rejected because he failed to develop the argument.
For developers, the line is sharp. Proving your partner wronged you is one fight. Proving that wrong cost you the money is another - and the second one needs evidence the court can actually stand on.
