About

Hartwell Law, the Oklahoma City practice of attorney David P. Hartwell, has spent more than three decades helping families plan ahead and move through the sensitive work of estate planning, wills and trusts, guardianship, and probate. Born and raised in Oklahoma City, Hartwell earned his accounting degree and law degree from Oklahoma City University and has been admitted to practice in Oklahoma state courts, the U.S. District Court for the Western District of Oklahoma, and the Tenth Circuit Court of Appeals since 1990. The firm is known for personal, appointment-based counsel that turns a client’s wishes, family circumstances, and assets into tailored legal documents rather than generic forms. Whether someone is creating an estate plan, updating a trust, or guiding a loved one’s affairs through guardianship or probate, the office emphasizes clarity, compassion, and practical next steps. From its Sovereign Row office, Hartwell Law presents itself as a local guide for life’s important decisions—protecting what matters most and helping families enter their next chapter with confidence.

Why we like Hartwell Law

Hartwell Law earns a place at #2 among Oklahoma City trust attorneys because attorney David P. Hartwell has spent more than three decades focused on the work families actually need: estate planning, wills, trusts, guardianship, and probate. Born and raised in Oklahoma City, he brings an accounting degree and a 1990 law degree from Oklahoma City University, plus admission to Oklahoma state courts, the U.S. District Court for the Western District of Oklahoma, and the Tenth Circuit. That mix of local roots, tax-aware training, and long practice lets the office turn a client’s wishes, assets, and family circumstances into tailored documents—and update them when a trust needs an amendment. What separates the firm is its personal, appointment-based approach: one attorney walking clients through sensitive next steps rather than routing them through a large, general-practice machine. As a member of the Oklahoma Bar Association serving from a single Sovereign Row office, Hartwell Law stays close to the community it has advised since 1990.
