Minnesota, Iowa, and Nebraska
FOUNDED IN 2003
Thompson Law is an estate and business planning firm serving individuals, families, farmers, ranchers, and business owners throughout the Midwest. On July 1, 2026, Thompson Law merged with German Law of Grand Forks, bringing together two experiencedfirms with offices in Sioux Falls and Grand Forks.
Our attorneys work with a wide range of clients and planning needs. That includes straightforward estate plans for families who simply want to get their affairs in order, business and farm succession planning, Medicaid and long-term care planning, trust administration, and more advanced estate and trust planning for families with significant assets.
No two clients are exactly alike. Neither are their plans.
We take the time to understand what a client owns, who and what they care about, and what they want their plan to accomplish. Then we explain the options, work through the decisions, and help put the right legal documents and planning in place.
Sometimes the goal is fairly simple: make things easier for your family when you’re gone. Other situations involve a family business, a farm or ranch, long-term care concerns, complicated family dynamics, significant wealth, tax planning, or trusts that may last for generations.

Our non-traditional planning methods include special provisions and protections in Living Trusts, Wills, Powers of Attorney, Living Wills, Irrevocable Trusts, Family Limited Partnerships, and Charitable Gifting Strategies.
Family-Owned Businesses & Farms
Our law firm focuses in estate planning assistance for the unique needs of Family Businesses and Farms. We help clients preserve this important part of their legacy for future generations.
Incapacity Planning
Our law firm helps clients create a plan to handle their affairs in the event they are incapacitated by illness or injury before the pass away. This includes planning to avoid a Living Probate or Guardianship proceeding.
IRA & Retirement Planning
Our law firm has experience in the complex area of estate planning with IRAs and other retirement plans. We help ensure clients and their beneficiaries are protected by employing tax reduction techniques.
Asset Protection & Business Planning
We help clients who are small business owners and those who are most susceptible to being sued by assisting with Lawsuit and Asset Protection. We also assist with Business Succession Planning and Small Business Planning. Some of the tools and strategies used are Family Limited Partnerships, Limited Liability Companies and Buy-Sell Agreements.
Estate Planning and Your Pets
Our firm cares about the welfare of your pets. Your beloved pets need to be protected in the event you are no longer there to take care of them. Estate Planning and implementing a Pet’s Trust can ensure that your pets are provided for after your death.
Special Needs Planning
We offer assistance to clients who have family members with special needs by creating Special Needs Estate Plans. These tailored plans help them preserve government benefits while having their loved ones cared for in all areas of their life: financial, education, medical and most importantly, their emotional and personal needs in the future.
Trust Administration & Probate
We help families who have experienced the loss of a loved one with the ensuing Probate or Trust Administration process. It is our goal to ensure the estate plan is fulfilled according to the clients’ wishes. We have assisted hundreds and hundreds of trustees and executors in fulfilling their fiduciary responsibilities.
Estate Plan Review
We help clients preserve their wealth and achieve their long-term financial goals. Our attorneys work closely with clients’ financial advisors to make sure their estate plan and their financial plan are coordinated and meet our clients’ goals.
Existing Clients: Call our office for an “Accountability Review” to make sure your plan still fits. Life changes, so may your estate plan.
Either way, the approach is the same. Understand the client. Understand the goal. Explain the options clearly. Then build a plan around it.
