For over 30 years, our founder, Abby Wool Landon, has been helping her clients plan for their future, and the future of their families, applying her expertise in estate planning, business succession and tax planning, and probate and trust administration. Abby brings a personalized hands-on approach to each of her client’s needs.

Abby developed many of our unique firm systems, among which is the Emerging Estate Plan a fixed fee program for young adults with emerging estates, and the ILIT Plus™ for larger estates. These are two examples of the unique programs developed by Abby which are available to clients of Wool Landon.

Abby is known throughout the community as a problem-solver. She is an excellent strategist in a conflict, which makes her the right lawyer to help clients and lawyers resolve complex situations and bring families together with solutions to potential problems. She serves as Trust Protector for many of her clients and their irrevocable trusts.

Although it has been decades since Abby was an active courtroom lawyer, her extensive courtroom experience in family law and fiduciary disputes gives her important perspective and experience that she applies when counseling her clients on their individual situations.

Throughout her career Abby has been a consistent scholarly contributor to her field of practice by giving speeches, interviews, presentations, and seminars. Abby has testified as an expert witness in a multinational dispute involving multiple states and two countries. She is sought after for her tax advice related to estate planning.

Some examples of her most recent contributions include: A speaking engagement, “From State to State: Community Property in Transit,” presented at the Connecticut State Bar Association annual meeting on June 10, 2019; and a presentation called “Building a Magical Legacy to Span Generations: Estate Planning Lessons from Harry Potter,” designed to inform clients, in a fun and engaging way, about the importance of up-to-date planning documents.

Abby is the immediate past chair of the Estate Planning Practice Group and a member of the Business Department and Tax Practice Group at Tonkon Torp LLP. She creates estate plans that include wills, trusts, asset protection devices, and family business succession planning. Abby also assists clients in navigating probate and trust administration, and provides expert support for contested probate and other fiduciary disputes. She has significant experience in: corporate tax law and tax partnerships, multiple-generation trust and estate planning, tax domicile analysis (including international applications and planning for non-citizen residents), charitable planning, marital trust planning for step-families, and premarital and post-marital agreements.

In addition to her estate planning background, Abby has 29 years’ experience in business law, helping individual and corporate clients with tax, complex business transactions, mergers and acquisitions, corporate management, business succession, and wealth management. As a small business owner, director, and member of several family partnerships, Abby brings hands-on experience to her clients.

A popular speaker, she has presented at CLE seminars throughout the Northwest, speaking on asset protection, managing community property from state to state, elder financial abuse, and estate planning for families in conflict.

Abby has extensive courtroom experience, including testifying as an expert witness in a multinational dispute involving multiple states and two countries. She is involved in community education and teaching to private groups to raise awareness of the importance of wills and trusts, corporate formalities, tax, and gift and estate tax planning to maximize profit and avoid conflict.
