The firm

Three lawyers. One long view.

We are deliberately small. Every matter is handled by an attorney whose name is on it, every attorney is licensed in Missouri and Kansas, and nobody here will ever describe your family as a file.

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.

Marcus J. Amory

Partner · Family law · Collaborative practice

In family law the verdict is not the ending; the family is. I measure outcomes by how they hold up at a graduation, five years on.

Marcus joined Margaret in 2015 and became a name partner in 2018, building the firm's family law practice on a settlement-first philosophy backed by meticulous trial preparation. Before private practice he served as a staff attorney with a legal aid family unit, and later accepted guardian ad litem appointments in contested custody matters, an experience that permanently shaped how he weighs what children carry out of these cases.

He is trained in collaborative practice and is a registered family mediator, and roughly a third of his docket resolves without a contested filing. The remainder benefits from the fact that opposing counsel know he does not bluff about trying a case.

Marcus grew up in Kansas City, Kansas, coaches a spring soccer team of eight-year-olds with more enthusiasm than tactical success, and keeps a paisley collection that the rest of the firm has voted not to discuss.

Leila N. Haddad

Associate · Probate · Guardianships & conservatorships

Probate clients rarely need to be impressed. They need to be told, in plain sentences, what happens next, and then they need it to happen.

Leila joined the firm in 2021 from a judicial clerkship with a Missouri circuit court, where she watched a full docket of probate matters from the bench's side and developed her defining professional habit: filings that answer the court's questions before they are asked.

Her practice concentrates on estate administration, guardianships and conservatorships for elderly and disabled family members, and the small-estate procedures that spare families a full administration. Clients consistently describe her the same way: she calls back the same day, and she never makes you feel foolish for asking.

She serves on the young lawyers board of a Kansas City legal aid organization and hosts a monthly supper club whose rotating theme has never once been observed by its members.
