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.

Unity Legal Services, the Norman practice of attorney Monica “Mona” Guziar, focuses solely on estate planning, probate, guardianship, and Oklahoma mineral interests. A 2017 graduate of the University of Oklahoma College of Law, Guziar built the firm around a simple promise: listen first, then create the plan that protects a family’s assets, goals, and values—and nothing more. Typical work includes wills, revocable and irrevocable living trusts, durable powers of attorney, living wills, probate administration, and guidance on royalty and lease issues that often sit inside an Oklahoma estate. Beyond the office on West Main Street, she teaches free community estate-planning classes and stays active with Big Brothers Big Sisters, Rotary, Fostering Futures, and Norman Kiwanis. That mix of a narrow practice and local teaching has made Unity Legal Services a familiar stop for Cleveland County families who want a clear plan rather than a stack of extra documents.

McBride & Associates, P.C. has served Oklahoma families since 1996 with estate planning, trusts, wills, probate, guardianship, business planning, and bankruptcy from offices in Edmond and the Moore–Oklahoma City area. Founder L. David McBride, an electrical-engineering graduate of the University of Oklahoma who later studied law at OU and Queen’s College, Oxford, focuses his practice on trusts, wills, probate, and business planning and regularly teaches those subjects to civic groups and other attorneys. The firm treats a trust as a practical tool—not a luxury document—used to keep a client in control, avoid an unplanned probate, and tailor fiduciaries and beneficiaries to a real family, including blended households and special-needs planning. Attorneys Karina R. Lueck and Teresa D. Gerber round out the team on estate planning, probate, business matters, and employment work. Clients are invited in for a free first-hour consultation so the plan can be custom-fit rather than pulled from a single template.

Cortes Law Firm, founded in 2013 by Oklahoma City attorney Stephen L. Cortes, concentrates on estate planning, probate, and trust administration for families and business owners across the metro. Cortes, licensed in Oklahoma since 1999 and a graduate of Oklahoma City University School of Law, previously served as general counsel to Governor Brad Henry and as a referee for the Oklahoma Court of Civil Appeals. The firm’s “client-centered” process starts with a sit-down about goals and fears, then turns those into customized documents—revocable living trusts, wills, powers of attorney, living wills, special-needs and charitable trusts, guardianship planning, and trust administration. Attorney Elaine Pok-Wright handles probate with the same family-first approach, and the office offers Spanish-language service, virtual meetings, and flat-fee options on many uncontested matters. From its Broadway Extension office, Cortes Law Firm’s aim is simple: while you are living, stay in control of what you own, and when you cannot, leave clear instructions about who receives what, and when.

Postic & Bates, P.C. is a south Oklahoma City family firm that has practiced estate planning, probate, real estate, elder law, and adoption since Martin Postic, Jr. opened his Moore office in 1980 and later built the Shadowlake Law Center. Julie E. Bates joined in 1987, and their son David Postic became part of the practice in 2016 after graduating with honors from the University of Oklahoma College of Law—where he now teaches Wills & Trusts as an adjunct. The firm’s planning work covers living trusts, wills, durable powers of attorney, asset protection, Medicaid and special-needs planning, trust administration, and the real estate that so often sits inside an Oklahoma estate. Attorneys appear in Oklahoma, Cleveland, Canadian, McClain, Grady, and Pottawatomie Counties and treat the job as making sure the right people can care for a client in life and receive what they should after death. First meetings are offered as a free, no-obligation consultation.

Parman & Easterday is an Oklahoma City estate-planning and elder-law firm that also serves Tulsa, built around founder Larry V. Parman’s vow that no family should go through the unplanned mess he watched his own family face. Licensed in Oklahoma since 1981 and in Missouri since 1974, Parman is an Accredited Estate Planner and, the firm notes, Oklahoma’s only member of the American Academy of Estate Planning Attorneys—a designation that requires far more estate-specific training each year than the state bar minimum. The office on Quail Pointe Drive customizes wills, trusts, probate, Medicaid planning, asset protection, business succession, and trust administration so a legacy is a help to loved ones rather than a burden. Parman has written several plain-language books on Oklahoma estate planning and still teaches through the firm’s seminar program, putting education ahead of the engagement letter. The work is purpose-driven on purpose: protect assets while the client is alive, and leave clear instructions after.

Derryberry & Naifeh, LLP has practiced in Oklahoma City since 1979, pairing a mid-size bench with the personal follow-through of a smaller shop from its office on North Lincoln Boulevard. The firm’s roots run through Oklahoma public life: co-founder Larry Derryberry was a former state representative and attorney general, and estate-planning attorney Don Nevard previously served as general counsel to the Oklahoma Tax Commission. That tax and government background shows up in the wills, revocable and irrevocable trusts, living wills, special-needs and charitable trusts, business-succession plans, and probate work the firm handles for families whose estates include companies, mineral rights, or investment real estate. Lawyers also represent executors, trustees, and beneficiaries when an estate is already in court. New estate-planning and probate clients are invited to start with a free consultation.
