Margaret S. Hartwell
Founding Partner · Estate planning · Probate & trust administration
“An estate plan is a letter to the people you love, written in the only language a court is required to honor. It should read like you.”
Margaret founded the firm in 2012 after nine years in the trusts and estates group of a large downtown Kansas City firm, where she learned both the craft of sophisticated planning and the conviction that families should not need a conglomerate to get it. She has spent her career on one question: how families keep what they have built, and how they pass it on without passing on conflict.
Her practice centers on estate planning for families and business owners on both sides of the state line, and on guiding personal representatives and trustees through administrations that stay out of the newspaper and out of litigation. Probate judges see her often enough to know her filings arrive complete.
She teaches an annual continuing legal education session on Missouri nonprobate transfers, and spends an unreasonable share of her free time restoring a 1920s Waldo bungalow that she describes as her longest-running administration.
