Families today often look different from generations past. Many parents enter a new marriage bringing children from previous relationships. These blended families may be closely connected, but they also face unique challenges when it comes to estate planning.
If you are remarried or part of a blended family, creating a clear and legally sound estate plan is one of the most important steps you can take to protect your spouse, children, and stepchildren. Without one, your assets may not go to the people you intended, and family relationships can be strained for years.
A Common Example: When Good Intentions Go Wrong
Consider this common scenario. Michael and Susan each have children from prior marriages. They get married later in life and build a life together. Wanting to keep things simple, they each sign a basic will that leaves everything to the other spouse at death.
Years later, Michael passes away. All of his assets go to Susan, just as the will directs. A few years later, Susan remarries and executes a new will leaving everything to her new husband. When Susan dies, her entire estate passes to her new spouse, and Michael’s children receive nothing from their father’s estate.
This situation happens far more often than most people realize. Without planning that protects both spouses’ families, children from the first marriage can be unintentionally disinherited.
Common Challenges in Estate Planning for Blended Families
Every blended family is different, but several recurring challenges arise again and again. Having these conversations now can also help you avoid common blended family inheritance issues like:
- Comingled assets: Couples often own a mix of joint property (acquired during marriage) and separate property (owned before marriage or inherited). Over time, these assets can become mixed together, making it difficult to determine who owns what.
- Family conflict: Disputes can easily arise between biological children, stepchildren, and surviving spouses. Without a clear plan, a personal representative may be forced to make difficult choices that strain family relationships.
- Accidental disinheritance: Stepchildren have no automatic inheritance rights in Tennessee unless they are specifically named in a will or trust. If not included, they can be completely excluded from an estate.
- Risk of intestacy: If someone dies without a will, Tennessee law determines who inherits. The surviving spouse and biological children divide assets according to statutory formulas, but stepchildren will not inherit at all.
Key Estate Planning Tips for Blended Families
There is no one size fits all approach. Your plan should reflect your unique family situation, your goals for fairness, and your desire to minimize conflict. Below are three common approaches.
1. Simple Mirror Wills
In this plan, both spouses create wills leaving everything to the other spouse at death. After the second spouse passes, the remaining estate is divided among all children.
Example: Michael and Susan sign mirror wills that say, “I leave everything to my spouse, and if my spouse has died, I leave everything equally to all our children.”
Pros:
• Easy and inexpensive to create
• Straightforward to understand
• Avoids complexity during the first spouse’s lifetime
Cons:
• Provides no protection for the first spouse’s children
• The surviving spouse can freely change their will after the first spouse dies and cut out those children
• All assets remain under the surviving spouse’s full control and can be redirected elsewhere
2. Separate Estate Plans with Marital Trusts
In this approach, each spouse creates their own will or revocable living trust that provides for the surviving spouse but also protects the inheritance for that spouse’s children.
A marital trust is a common strategy for blended families. When one spouse passes away, their assets are placed into the trust for the benefit of the surviving spouse. The survivor may receive income from the trust, such as interest, dividends, or rental proceeds, and may also have access to the principal for support. After the surviving spouse’s death, the remaining assets in the trust are distributed according to the first spouse’s wishes, typically to that spouse’s children, ensuring their inheritance is preserved.
Example: Michael’s trust provides that Susan receives all income from his trust during her lifetime, but the principal passes to Michael’s children at Susan’s death.
Pros:
• Protects each spouse’s biological children
• Ensures the surviving spouse is cared for
• Prevents unintentional disinheritance
• Can reduce estate taxes in some situations
Cons:
• More complex and expensive to create
• Requires naming a trustee to manage the trust
• The surviving spouse has limited access to the deceased spouse’s assets
3. Joint Revocable Trust with a Marital Trust Component
A third option is to create a joint revocable trust together. Both spouses transfer assets into one shared trust. During their lifetimes, they can manage the trust together. When one spouse dies, the trust splits into separate shares: one containing the surviving spouse’s assets and the other containing the assets of the deceased spouse. The assets of the spouse that passed away usually go into a martial trust for the benefit of the surviving spouse.
Example: Michael and Susan establish the “Michael and Susan Family Trust.” At Michael’s death, his portion of the trust is held for Susan’s benefit during her lifetime. When Susan later passes, Michael’s portion is distributed to his children, while Susan’s portion goes to hers.
Pros:
• Simplifies management during marriage
• Allows coordination of assets under one structure
• Provides built in protection for both sides of the family
Cons:
• Requires cooperation and trust between spouses
• Slightly higher cost and more complex to administer
• May require ongoing trustee involvement to ensure fairness
Practical Tips for Blended Family Estate Planning
1. Update your beneficiaries – Regularly review life insurance, retirement accounts, and payable on death designations to ensure they reflect your wishes.
2. Document your intentions clearly – Ambiguity creates conflict. Be explicit about who receives what and when.
3. Communicate openly – Having honest conversations with your spouse and adult children now prevents painful misunderstandings later.
4. Name contingent beneficiaries – Always name backup beneficiaries in case your primary beneficiary passes away or cannot inherit.
5. Work with an experienced estate planning attorney – Tennessee’s estate and probate laws have unique rules that affect blended families. An attorney can design a plan that ensures your intentions are carried out and your family is protected.

Blended families require special care when it comes to estate planning. Without a clear plan, assets can easily end up in the wrong hands, and children from prior marriages can be unintentionally left out.
