How Divorce, Remarriage & Blended Families Affect Wills and Trusts

How Divorce, Remarriage & Blended Families Affect Wills and Trusts

How Divorce, Remarriage & Blended Families Affect Wills and Trusts

Family dynamics have changed significantly over recent decades. Today, blended families—where one or both spouses bring children from previous relationships—are increasingly common. While these families create new bonds and opportunities for love and connection, they also introduce complex estate planning challenges that many people don’t anticipate until it’s too late.

At Horn & Johnsen SC, we’ve helped countless Wisconsin families navigate the intersection of changing family structures and estate planning. Whether you’re going through a divorce, entering a second marriage, or building a blended family, understanding how these life events affect your will and trust is essential to protecting everyone you care about.

Why Divorce Changes Everything About Your Estate Plan

When you created your will or trust during your marriage, your spouse was likely named as your primary beneficiary, executor, trustee, healthcare agent, and financial power of attorney. After a divorce, these designations don’t automatically disappear—and that can create serious problems.

What Happens to Your Will After Divorce?

Under Wisconsin law, divorce automatically revokes certain provisions in your will that benefit your former spouse. Specifically, any disposition or appointment of property to your ex-spouse is treated as if they predeceased you. However, this automatic revocation has important limitations:

  • It only applies to ex-spouses—not their relatives who may have been named as contingent beneficiaries
  • It doesn’t affect beneficiary designations on life insurance policies, retirement accounts, or payable-on-death accounts
  • It doesn’t update your executor or trustee appointments if your ex-spouse was named in those roles
  • It doesn’t address guardianship provisions for minor children

The bottom line: relying on automatic revocation is risky. You need to proactively update your estate plan after divorce.

The Beneficiary Designation Problem

One of the most common—and costly—mistakes divorcing individuals make is forgetting to update beneficiary designations. These designations operate outside of your will and pass directly to the named beneficiary regardless of what your will says.

Consider this scenario: Mark divorced his first wife but never changed the beneficiary on his $500,000 life insurance policy or his 401(k). When he passed away five years later, his current wife and two young children received nothing from these assets—everything went to his ex-wife, because she was still listed as the beneficiary.

Review and update beneficiary designations on:

  • Life insurance policies
  • Retirement accounts (401(k), IRA, pension plans)
  • Bank accounts with payable-on-death (POD) designations
  • Investment accounts with transfer-on-death (TOD) designations
  • Annuities

Remarriage: Balancing New Commitments with Existing Obligations

Entering a second marriage brings joy and new beginnings, but it also requires careful estate planning to balance your commitment to your new spouse with your obligations to children from your previous marriage.

The Classic Blended Family Dilemma

Here’s a common situation we see: Sarah and Tom, both in their 50s, get married. Each has adult children from previous marriages. Sarah wants to ensure Tom is cared for if she dies first, but she also wants her estate to ultimately pass to her children, not Tom’s children.

Without proper planning, one of two outcomes typically occurs:

Scenario 1: Sarah leaves everything to Tom outright. Tom remarries after Sarah’s death or simply leaves everything to his own children. Sarah’s children receive nothing.

Scenario 2: Sarah leaves everything directly to her children. Tom is left with no support and may face financial hardship, creating family conflict.

Neither outcome aligns with Sarah’s true wishes.

Solutions for Blended Families

1. Qualified Terminable Interest Property (QTIP) Trust

A QTIP trust allows you to provide for your current spouse during their lifetime while ensuring your assets ultimately pass to your chosen beneficiaries (typically your children) after your spouse’s death. Your spouse receives income from the trust and may also receive principal for health, education, maintenance, and support, but cannot change who receives the trust assets after their death.

2. Marital Property Agreements

Wisconsin is a marital property state, meaning assets acquired during marriage are generally owned equally by both spouses. A marital property agreement (prenuptial or postnuptial) can clearly define what property belongs to whom and how it will be distributed at death. This is especially valuable when both spouses bring significant assets or children from previous relationships into the marriage.

3. Life Insurance Strategies

Life insurance can provide liquidity to ensure your new spouse is financially secure while preserving other assets for children from a previous marriage. You might establish an irrevocable life insurance trust (ILIT) with your children as beneficiaries while leaving other assets to your spouse.

Special Considerations for Blended Families

Minor Children in Blended Families

When minor children are involved, estate planning becomes even more critical. Consider these questions:

  • Who will serve as guardian if both biological parents die?
  • Should your new spouse have access to assets intended for your minor children?
  • How can you ensure funds are used for your children’s benefit?

A trust can protect assets for minor children while specifying who will manage those funds and how they can be used. This prevents assets from being controlled by an ex-spouse or potentially misused.

Adult Children and Stepparent Relationships

Even when all children are adults, estate planning requires sensitivity. Adult children often have strong feelings about how assets should be distributed, especially if they feel their inheritance is threatened by a stepparent.

Open communication is essential. While you’re not required to disclose all details of your estate plan to your children, discussing your general intentions can prevent hurt feelings and potential legal challenges after your death.

Naming the Right Fiduciaries

In a blended family, naming executors and trustees requires careful thought:

  • Will your new spouse and your children be able to work together effectively?
  • Would a corporate trustee or professional fiduciary provide more neutral administration?
  • Should you name co-trustees from both sides of the family?

Choose fiduciaries who can navigate family dynamics diplomatically and put your wishes above personal interests.

Don’t Forget These Critical Updates

When divorce or remarriage occurs, review and update:

Estate Planning Documents:

  • Will
  • Revocable living trust
  • Durable power of attorney for finances
  • Healthcare power of attorney
  • Living will/advance directive

Beneficiary Designations:

  • Life insurance policies
  • Retirement accounts
  • Bank and investment accounts
  • Annuities

Ownership Structures:

  • Real estate titles
  • Vehicle registrations
  • Business ownership documents
  • Joint bank accounts

Other Important Documents:

  • Healthcare directives and HIPAA authorizations
  • Digital asset access instructions
  • Letters of instruction to executors and trustees

Wisconsin-Specific Considerations

Wisconsin law has specific provisions that affect blended families:

1. Marital Property System: Wisconsin is one of few states with a marital property system (similar to community property). Understanding how this affects your estate plan is crucial, especially in second marriages.

2. Elective Share Rights: A surviving spouse in Wisconsin has the right to claim a percentage of the deceased spouse’s estate even if the will provides differently. Proper planning can address this to ensure your children aren’t disinherited.

3. Step-Parent Adoption: If your new spouse adopts your children, this creates legal parent-child relationships that affect inheritance rights and can simplify estate planning.

The Cost of Inaction

We’ve seen too many families torn apart by estate planning oversights. Consider these real consequences:

  • Unintended inheritance: An ex-spouse receives assets you intended for your children
  • Family conflict: Step-siblings battle over assets without clear guidance
  • Financial hardship: Your current spouse is left without support because you prioritized protecting your children’s inheritance
  • Probate complications: Ambiguous documents lead to expensive court proceedings
  • Disinherited children: Your new spouse receives everything and your children from a previous marriage receive nothing

These outcomes are preventable with proper planning.
