You probably remember the moment you first put your estate plan in place. Maybe it was when you bought your home, welcomed a child, or wanted to make sure your farm or business would be protected. But here’s the reality: the plan you wrote years ago may not match your life today.
In South Dakota, where families often balance farmland, businesses, and blended households, even small life changes can make old documents unreliable. At ND Estate Services, we’ve seen too many families assume their plan will “just work,” only for their loved ones to discover later that beneficiaries are outdated, guardians aren’t named, or assets aren’t covered.
In fact, a nationwide problem: many adults in the U.S. have experienced family conflict because an estate plan wasn’t in place.
The truth is simple: an estate plan is only as strong as it is current. This blog will walk you through 8 clear signs that it’s time to update your estate plan, so your wealth, your wishes, and your family stay fully protected.
1. Marriage, Divorce, or Remarriage
Getting married, divorced, or remarried changes your family structure, and your estate plan needs to keep up. In South Dakota, a surviving spouse has legal rights to a share of your estate under the elective share rules (SDCL § 29A-2-202). That means if your documents don’t account for a new spouse, the law may step in and create results you didn’t intend.
For example, if you divorce but forget to update your will or beneficiary forms, your ex-spouse could still be listed to inherit life insurance or retirement accounts. Updating your estate plan ensures the right people are named and your current spouse, children, or stepchildren are protected.
2. Birth or Adoption of a Child or Grandchild
Few moments change your priorities like welcoming a new child or grandchild. Without updating your estate plan, that child may not be included in your will or trust.
Have you thought about who would take care of your kids if something happened to you? In South Dakota, naming a guardian in your will is the only clear way to decide who would care for your minor children (SDCL § 29A-5-201). Without it, the court will step in and make the decision for you.
Adding new children or grandchildren to your estate plan also ensures they are provided for financially. Whether that’s updating a trust, naming them as beneficiaries, or setting aside accounts for their education, these updates make sure your plan grows with your family.
3. Death of a Beneficiary or Fiduciary
Life doesn’t always unfold the way we expect. If a beneficiary, executor, or trustee named in your estate plan passes away, your documents need to be revised. Otherwise, your plan could “fail” and require the court to step in.
Imagine naming your brother as the executor of your estate, only for him to pass away years before you. If you haven’t named an alternate, the court may appoint someone else, possibly someone you wouldn’t have chosen. A quick update prevents these gaps and ensures the right people are still in place.
4. Significant Changes in Wealth or Assets
Buying a farm, starting a business, inheriting land, or even selling property can all shift the balance of your estate. If you don’t update your plan, those changes may not be covered. In South Dakota, family farms and ranches often represent both livelihood and legacy, but they can also be hard to divide fairly without advance planning.
For example, if one child wants to continue farming and another does not, your plan should spell out how that property will be managed. Updating your estate plan after major financial changes ensures your wealth is distributed in ways that support both your goals and your family’s needs.
5. Relocation to or from South Dakota
Moving across state lines is more than just a change of address. Each state has its own probate rules, tax laws, and requirements for powers of attorney or healthcare directives. South Dakota has no state estate or inheritance tax, but if you move to a state that does, your estate plan may need a complete overhaul.
Even if you’re moving into South Dakota, your old documents may not comply with local law. Reviewing your estate plan after any move helps ensure your documents will be honored in your new state.
6. Changes in State or Federal Law
Laws don’t stay the same forever. Federal estate tax thresholds shift, and South Dakota has updated provisions for healthcare directives and probate procedures over time.
For example, South Dakota’s Health Care Decisions Act (SDCL Chapter 34-12D) governs advance health care directives. If your documents were drafted before these provisions were updated, they may not fully reflect what current law requires.
Keeping your plan current with legal changes ensures your wishes are followed and that your family doesn’t face unnecessary court challenges. A periodic review with a professional familiar with South Dakota law can give you peace of mind.
7. Shifts in Health or Family Dynamics
If you’ve experienced a health scare or received a new diagnosis, it’s time to take another look at your estate plan. Powers of attorney and healthcare directives only work if they reflect your current wishes and the people you trust right now. Without an update, decisions about your care could end up in the wrong hands.
Family changes matter just as much. Maybe you’ve become closer to someone who wasn’t part of your plan before, or perhaps a relationship has broken down. Your estate plan should grow with those changes, it’s a living document, not a snapshot of your life from years ago.
8. It’s Been More Than 3–5 Years
Even if life feels steady, estate plans don’t age well without attention. A will or trust written five years ago might list an old address, an outdated account, or a beneficiary who’s no longer in your life. Those small details can cause major headaches in probate.
Think of it like maintaining your farm equipment or your car. You wouldn’t go years without a tune-up. The same goes for your estate plan—regular check-ins keep it running the way you intend, so it’s ready when your family needs it.
The Risks of Ignoring Updates
What happens if you never revisit your estate plan? The consequences can be more costly and more painful than most families expect. Outdated beneficiaries may leave property to someone you never intended. Probate can drag on for months, draining both time and money. Family members may even end up fighting over guardianship or assets.
One of the most common and heartbreaking examples we see is a life insurance policy that still names an ex-spouse. That single oversight can redirect thousands of dollars away from the people you love most. The good news is that these mistakes are completely preventable. Updating your plan regularly keeps control in your hands and spares your family from unnecessary stress.
Keep Your Estate Plan Current, Keep Your Family Protected
Estate planning is about peace of mind. But that peace only lasts if your plan stays up to date. South Dakota families face unique considerations, from farmland to blended households, and your plan should reflect those realities.
If you haven’t reviewed your estate plan in years, or if any of these 8 signs apply to you, now is the time to take another look. Updating today ensures your family is protected tomorrow.
