Hey there, Legal Tea Listeners – This is your host, Jenny Rozelle. Welcome back for another episode, which is a “current trends” topic where we talk about things going on currently that are relevant and pertinent to my estate and elder law world, and/or maybe things I’ve seen on the news or stumbled across on social media. Well, today we are diving into a topic that sits right at the intersection of modern technology and traditional estate planning — and that intersection is becoming more, let’s call it, crowded by the day. Meaning it’s going to become a bigger and bigger thing and issue – just watch! Today, we are talking about like consumer DNA testing and how services like 23andMe and AncestryDNA are creating unexpected complications in estate administration, inheritance claims, and family relationships after someone has passed away. Let’s dive in…
For many people, DNA testing starts out as something lighthearted. You may be curious about your ancestry, or maybe you want some general health insights. You spit in a tube, mail it off, and a few weeks later there you are, scrolling through results on your phone. But according to a recent article on JD Supra, those same DNA tests are now being used in legal contexts — particularly when estates are being settled and someone new suddenly appears claiming to be related to the deceased. I have a great movie scene or TV show scene of this all happening, by the way, so I’m sure it’s a matter of time before this is the subject of a whole movie!
What makes this topic and trend especially challenging is that SOMETIMES these discoveries happen after death. For example, during life, someone may never have known they had a biological child, or they may have known but never acknowledged it. In other cases, the child may have known about the biological relationship but had no legal proof. DNA testing sure changes that. It provides scientific evidence that can reopen questions families thought were long settled. According to JD Supra, estate planning attorneys are seeing an increase in claims from individuals who discovered their biological connection only after a parent or relative had already passed away. I’m curious, Legal Tea Listener, have you heard of this happening to a family member or friend yet? Let me know if you have!
So … to understand why this matters, it is important to talk about how estate planning traditionally works. Most people plan around the family they know. They think about their spouse, their kids, maybe stepchildren (maybe!)n, and often grandchildren. Estate plans are usually drafted based on those known relationships. But DNA testing has introduced a new layer — proof of biological relationships that may never have been part of the family narrative. According to JD Supra, that proof can create legal ambiguity when estate documents may not be specific enough.
One real-world example discussed in recent reporting involves a woman who discovered through DNA testing that she was biologically related to a man who had already died. She connected with relatives, confirmed the relationship, and eventually asserted a legal claim to a portion of a significant financial recovery related to his estate. Even though the claim was ultimately limited by timing and state law, the damage was done. Families who believed everything was resolved suddenly found themselves dealing with lawyers, court filings, and emotional fallout. According to JD Supra, these types of cases are happening more and more.
It is also worth emphasizing something that surprises a lot of people: a DNA match does not automatically entitle someone to inherit. That is HUGE and needs to be repeated for purposes of this podcast and topic: a DNA match does not automatically entitle someone to inherit. Biology alone does not control inheritance. According to JD Supra, one of the most important factors is whether the person who died had a valid estate plan. A properly executed will or trust that clearly identifies beneficiaries generally controls who inherits, even if a biological child is discovered later. That is one of the strongest arguments for having an estate plan in place.
But where things go wrong is when estate plans are unclear, outdated, or nonexistent. If someone dies without a will or trust, state intestacy laws take over. Many of those laws prioritize biological relationships, which is where DNA testing suddenly becomes very powerful. According to JD Supra, some states allow biological children to inherit even if they were never acknowledged during life, while others require proof of acknowledgment, support, or a legal parent-child relationship. The rules vary widely, and most families do not know which version applies to them until it’s too late.
Even when someone does have a will or trust, the language used can create unintended consequences. Phrases like “my children,” “my descendants,” or “my issue” are common, but legally are fairly broad, right? According to JD Supra, if those terms are not defined, a court may have to decide whether a newly discovered biological child falls within that class. That decision may be based on state law definitions rather than what the person actually intended. You can see where this could get complicated quickly!
So here is a hypothetical that illustrates the issue. Imagine someone signs a will leaving everything “to my children, in equal shares.” At the time, they believe they have two children. Years later, after their death, a third biological child is discovered through DNA testing. If the will does not define “children,” a court may have to decide whether that third child is included. According to JD Supra, this is exactly the type of ambiguity that leads to litigation — not because the law wants to create conflict, but because the document didn’t provide enough guidance.
Courts may also look at whether there was any acknowledgment or relationship during life. Did the deceased ever provide financial support? Were there letters, birthday cards, or other evidence of recognition? According to JD Supra, even small acts can sometimes be used to support a claim of parentage when combined with DNA evidence. This can be especially difficult for families who had no idea such a relationship existed.
Timing plays a huge role in these cases as well. Many people assume that once probate is finished, everything is final. But according to JD Supra, that may not always hold true. Some DNA-based claims fail because they are brought too late, after deadlines have passed. Others succeed because they are raised early enough in the process. This uncertainty is part of what makes these situations so unsettling — families may think the estate is settled, only to find out surprise, it is not!
Another critical piece of this puzzle is understanding which assets are actually at risk. Not every asset is subject to probate or inheritance claims. Assets that pass by beneficiary designation — like life insurance policies, retirement accounts, and payable-on-death accounts — typically pass outside probate and are not affected by later-discovered heirs. According to JD Supra, this distinction highlights the importance of beneficiary planning alongside estate documents like Wills and Trusts. That is because a well-crafted Will or Trust can offer significant protection when they are properly drafted. Those documents can define beneficiaries very specifically and include language that limits who has standing to challenge distributions.
For example, according to JD Supra, Wills and Trusts can also include statements of intent that make it harder for someone to argue they were unintentionally omitted. While no document can prevent every lawsuit, clarity dramatically reduces risk.
As you can imagine, DNA-based claims can be extremely stressful for the family as well as the person or persons in charge – like the Executor. Executors often assume their role will be administrative — gathering assets, paying bills, making distributions – call it a day, right! But when a surprise heir appears, the role becomes much more complicated. According to JD Supra, fiduciaries have a duty to take these claims seriously, seek legal guidance, and avoid distributing assets prematurely. Ignoring a claim or handling it incorrectly can expose an executor to personal liability.
It is also important to recognize the emotional side of these disputes. These cases are not just about money (but money IS involved too!). They raise questions about identity, belonging, and long-held family secrets. According to JD Supra, even when claims are unsuccessful, they can permanently change family dynamics. That emotional toll is something estate planning attorneys are seeing more often as DNA testing becomes more common.
So what does all of this mean for you, my Legal Tea Listener? First, estate planning today requires a more thoughtful approach than it did even ten or fifteen years ago. Technology has changed how family relationships are discovered, and estate plans need to account for that reality. According to JD Supra, reviewing and updating your plan regularly is one of the best ways to protect your intentions. Second, if you don’t have an estate plan, relying on state law is increasingly risky. Intestacy statutes were not designed with modern DNA testing in mind. Without a plan, you may be inviting outcomes you never intended. According to JD Supra, a basic estate plan can go a long way toward preventing future disputes. And finally, if you are serving as an executor or anticipate serving in that role, do know and hear me loud and clear that these issues are becoming more common. So buckle up!
This is a great way to warp this topic/episode up – think of it this way: at the end of the day, DNA tests do not themselves create family conflict — they uncover it. That’s deep, isn’t it! And without careful planning, that discovery can spill into courtrooms in ways that are painful, expensive, and entirely avoidable. Estate planning is not just about distributing assets anymore. It is about managing uncertainty in a world where the past is easier than ever to uncover.
Alrighty, let’s wrap this episode up, shall we? Next week, we’re back to the “celebrity estate planning” type of episode – so, for this episode, I will be diving into what happened estate-wise following the death of The Velvet Underground musician, Lou Reed. So yeah, that’s next week, so until then, Legal Tea Listeners, be well and talk soon!
