About Toni

Learn Toni’s areas of practice.

Practice areas
  1. Estate planning
    Wills, Trusts, Wealth Transfer Planning, Charitable Planning, Gifting Strategies, and Farm/Business Succession Planning.

  2. Probate
    When someone dies, certain assets may to pass to that individual's heirs free of court interference; however, many assets do not automatically pass to those heirs without a court process. That court process is called probate.

  3. Trusts
    The attorneys and paralegal team at Sandin Law can help your successor trustee(s) deal with the complexities of administering your trust.

  4. Wills and living wills
    Without a will, your loved ones will likely have an intestate probate. Probate, in general, can be a costly public process in which the state determines who administers your estate and the distribution of your assets.

  5. Corporate and incorporation
    We are here to provide support and peace of mind in the areas of your business where the advice of an attorney can save you time, money, and help you avoid unnecessary liability and loss.

  6. Real estate
    Our attorneys and paralegals were raised by entrepreneurial parents, growing up in either farming families or small business/commercial real estate focused families, so we have a solid understanding of what those clients need.

Toni is the owner and founder of Sandin Law and is licensed to practice law in both North Dakota and Minnesota. She graduated with distinction in 2005 from the University of North Dakota School of Law and is also a Certified Public Accountant (CPA), having received her CPA designation in 2002. Toni received her undergraduate degree from the University of Saint Thomas where she majored in Accounting. With her unique blend of legal, tax and accounting knowledge, Toni provides a strategic advantage for her clients because of her ability to intricately understand multiple facets of estate and gift tax planning. Having grown up in an entrepreneurial family, Toni understands all aspects of being involved in a family business and the challenges that can come with it. Toni specializes in estate planning matters, including business succession planning, charitable planning, special needs planning, and estate and gift tax planning, probate and trust administration, and real estate.
While attending law school at UND, Toni was a member of the North Dakota Law Review, an Extern with the United States District Court for the District of North Dakota, and worked as a law clerk in the Grand Forks State's Attorney's Office. She spent five years as an Associate Attorney with Dorsey & Whitney in Fargo, North Dakota in their corporate and estate planning practice groups prior to opening Sandin Law in September of 2009, and from 2015-2018, she joined Gray Plant Mooty managing the Fargo's Trust, Estate and Charitable Planning group. Toni remains highly connected to both the legal and accounting industries through numerous areas of involvement, including being a member of Wealth Counsel, a member of Red River Valley Estate Planning Council, a member of the State Bar Association of North Dakota, a member of the Minnesota State Bar Association, a member of the American Institutes of Certified Public Accountants, and a member of the North Dakota Society of Certified Public Accountants.
Toni has been invited to speak at a number of events in the region on topics such as business succession planning, real estate, charitable giving, advanced estate planning techniques, as well as special needs planning. In 2011, Toni was featured in the Bismarck Tribune's Business Watch Magazine as a recipient of the "40 under 40" Award, which is published across the State of North Dakota, and in 2014, Toni was selected by Prairie Business Magazine as one of the "Top 25 Women in Business".
Toni is a native of Fargo, North Dakota and loves working in, living in, and giving back to her local community. Toni currently serves as a board member for the Red River Valley Estate Planning Council, the Sanford Foundation, and the Village Family Services Foundation. She also serves on the finance council to her parish, Sts. Anne & Joachim Catholic Church. In the past, Toni has served on the board of directors for the North Dakota Autism Center, co-chaired the Signature Chef event for the March of Dimes, and supports many different charities in her community, including the Jeremiah Program, the United Way, Habitat for Humanity, and Churches United for the Homeless.
When she is not serving her clients and her community, Toni enjoys yoga, water skiing, playing tennis, traveling, and spending time at the lake. Most of all she enjoys spending time with her husband, four children and their miniature poodle.

Professional and Excellent Attention to Detail
Elizabeth and I were in need of establishing our estate plan and Toni and her team provided excellent advice throughout the process. We worked closely with Kristen, who listened to our needs and put together a great plan for our family and took the time to walk through the plan in its entirety, and answer all of our questions. I would highly recommend Sandin Law for your estate planning needs.

Review of Toni Sandin and Sandin Law
Wholeheartedly, our family was very pleased with the law services Toni Sandin and Sandin Law provided us in many ways. We, as most families, needed help with estate planning, business transaction, transfer of wealth and health directives. She recommended a Revocable Family Trust. This helped with income and legal protection, as well as, future equal transfer of assets to our daughter’s families and designated non-profits we have supported for years. Around this same time we made the decision to have a retirement and business transfer. Toni represented ALL parties involved and was highly respected by all for her knowledge and professionalism. We were very pleased with her assistance with all these transactions. We consider Toni Sandin a friend, but as important, as an attorney and Sandin Law are wholeheartedly highly recommended by all.

Estate planning/Will
We were in need of updating our will and needing an estate plan. Our experience with Sandin Law was very easy and relaxed. Most people needing an Estate Plan, Will and Living Will really don’t know what the family, tax and legal pitfalls are and that may come into play. Sandin Law and staff were very knowledgeable and helpful as they counseled us on what would be the best path forward for our family. We felt so relieved to get this taken care of and are so happy we chose Sandin Law.

Sandin Law Exceeded My Expectations
Toni and her team are my go-to for business planning. Most recently, we consulted with them about splitting off a business line into its own entity. Toni made recommendations on how to best do that and took care of all the paperwork making the process simple for us.

Estate planning Attorney | Nov 23
Relationship: Fellow lawyer in community
"I endorse this lawyer. Toni is a high caliber lawyer, colleague, community leader and mentor to numerous people. She is highly effective, ethical and she employs genuine kindness and compassion toward people! When our team makes referrals to Toni, the clients always provide extremely positive feedback regarding Toni's legal services, expertise and effective guidance!"
Estate planning Attorney | Nov 23
Relationship: Worked together on matter
"I hired Toni as an expert witness in a complex fraudulent transfer case. One of our defenses was that in the event a fraudulent transfer occurred it was done for legitimate estate planning purposes prior to the issues arising in the lawsuit. Toni was fantastic. She was extremely well-versed in this area of the law. She was very easy to work with and was thoroughly prepared. When she was deposed it was clear she was the most knowledgable estate planning person in the room. With Toni's assistance as an expert we obtained a very favorable settlement for my client. So favorable, in fact, that creditors objected to the terms. With a full understanding of our defense and the risks the bankruptcy trustee had, the U.S. Bankruptcy Court confirmed the settlement agreement over the objections. I would not hesitate at all to higher Toni as an expert again. She was simply fantastic."
Estate planning Attorney | Oct 19
