David A. McCarville


Legal Assistant: Brandi Kline


David assists clients with estate planning and administration, probate litigation, Blockchain technology legal advice, and real estate/corporate transactions. In his work with individuals, couples, families and business owners, he serves as a trusted counselor who brings a multidisciplinary approach to help solve their legal problems and plan for the future. His clients know they can count on him to intervene personally, if he can, or put them in touch with another professional who can help.

Estate Planning for Individuals, Couples and Families. David wholeheartedly believes that every person needs an estate plan to protect their assets and preserve their wishes upon death and/or incapacity. Through the use of Living Trusts, Powers of Attorney, Advanced Health Care Directives and related documents, David empowers his clients with all the tools they need to make sure their estate avoids the costly and time-consuming probate process. Estate planning can be a scary and overwhelming prospect for many people; knowing that, David patiently leads his clients through the entire process, with the goal of ultimately replacing their fear with peace of mind. 

Estate & Succession Planning for Business Owners. David helps business owners safeguard their legacies by making sure their business interests are protected and pass to a worthy successor. He works through issues related to buy-sell agreements, assigning interests, asset protection, cash flow management, and effective use of life insurance and other financial tools to assure a smooth transition. He has also helped resolve complex situations where business and personal issues collide: for example, he recently helped an owner in a multi-owner partnership ethically protect his business assets while going through a divorce. David has significant experience working with owners of family farms and helping them navigate their specialized estate and business succession planning needs. 

Probate Litigation & Trust Administration. David represents parties involved in contested Probate Court actions such as Guardianship, Conservatorship, Formal Probate and Trust Administration matters. In this capacity, he also represents individuals and licensed fiduciaries who are acting as Trustees, Conservators or Personal Representatives of either a Trust or a Probate Estate. David has experience helping to resolve complex probate issues involving vulnerable adults, undue influence and fiduciary rights and obligations.  

Blockchain Technology Legal Advice. David is an Adjunct Professor at ASU’s Sandra Day O’Connor School of Law teaching a course titled Blockchain & Cryptocurrencies Law & Policy. David assists clients with Blockchain technology legal advice, estate planning and administration, probate litigation, and real estate/corporate transactions. In his work with individuals, couples, families and business owners, he serves as a trusted counselor who brings a multidisciplinary approach to help solve their legal problems and plan for the future. David is committed to understanding the use cases and legal implications of this technology and has become a recognized thought leader on Blockchain and related technologies. David provides legal counsel to startups and established companies seeking to leverage Blockchain or DLT to improve their business processes. David’s experience includes advising on issues related to Corporate Governance, Security Token Offerings, Smart Contracts, Estate Planning and Administration.

Real Estate/Corporate Governance & Transactional Matters. In the areas of real estate and corporate governance, David advises clients on both transactional and governance matters. His real estate and corporate law experience includes breach of contract and partnership disputes, well-sharing agreements, purchase and sale contracts, easements and adverse possession matters. David’s transactional practice benefits from his earlier work as a litigator: he is particularly adept at identifying potentially problematic contract terms when helping his clients review and negotiate leases, purchase and sale contracts, franchise-purchase agreements, and other contracts. His transactional practice also includes forming business entities for real estate holding companies, advising on corporate governance issues, and reviewing loan documentation.

Previous Career in Logistics and Transportation Industry. For many years, David enjoyed a rewarding career in logistics, planning and transportation industries in Washington, D.C., Nevada and Arizona. As a consultant with Booz Allen, he was involved in strategic planning associated with the transportation and disposal of nuclear waste for the U.S. Department of Energy’s Yucca Mountain Project. His previous experience also includes serving as a Nuclear Transportation Manager at Edlow International Company and as an Operations Manager at Matrix International Logistics.
