Divorce changes everything — including your estate plan. But here’s what many people don’t realize: even after a divorce is finalized, your ex-spouse may still have a pathway to your assets. Not directly, but through your children.
If you leave an inheritance to your children outright, those assets become part of their financial picture. And if your child is married to someone you wouldn’t choose to benefit — or if your child gets divorced themselves — those inherited assets could end up in the hands of someone you never intended to receive them.
This isn’t about being vindictive. It’s about making sure the wealth you worked hard to build actually benefits the people you love, in the way you intend.
How Your Ex Could Benefit from Your Estate
There are several ways your ex-spouse could end up with your money after you’re gone, even if your divorce decree says otherwise.
Through your minor children. If your children are minors when you die and they inherit assets outright, a court will likely need to appoint a guardian or conservator to manage those assets until the children reach 18. If your ex-spouse has custody, they will almost certainly be involved in managing those funds — and in many cases, they’ll be the one making spending decisions.
Even with the best intentions, this creates a situation where your ex-spouse has access to and influence over the money you left for your kids. And there’s very little oversight once a guardian is appointed, especially for day-to-day spending decisions.
Through your adult children’s marriages. If your adult child inherits money and commingles it with marital assets — deposits it into a joint account, uses it to buy a home with their spouse, or invests it alongside joint funds — that inheritance can lose its character as separate property. In a subsequent divorce, those assets may be considered marital property subject to division.
Massachusetts follows an “equitable distribution” model for divorce, which means the court has broad discretion to divide assets in a way it considers fair. While inherited assets are generally treated as separate property, commingling can blur the line — and a judge has the authority to include inherited assets in the marital estate if the circumstances warrant it.
Through your child’s financial mismanagement. If your child is financially dependent on their spouse — including an ex-spouse to whom they owe support obligations — an outright inheritance could effectively be redirected through alimony, child support modifications, or shared household expenses.
The Solution: Trust-Based Inheritance Planning
The most effective way to keep your assets out of your ex-spouse’s reach is to leave your children’s inheritance in a trust rather than distributing it to them outright.
A properly structured trust creates a legal wall between your assets and your children’s personal finances. Because the assets belong to the trust — not to your child personally — they are generally not considered marital property, are not reachable by your child’s creditors (including a divorcing spouse), and are managed by a trustee according to the terms you set.
Here are the key trust structures that protect against ex-spouse access:
Discretionary Trust
A discretionary trust gives the trustee full authority over when and how much to distribute to your child. Your child has no legal right to demand distributions, which means their spouse (or ex-spouse) has no claim to those funds either.
This is one of the strongest forms of asset protection. Because distributions are entirely at the trustee’s discretion, a divorce court generally cannot compel the trustee to distribute funds, and the trust assets typically won’t be counted in your child’s divorce settlement.
Spendthrift Trust
A spendthrift provision is a clause included in the trust that specifically prohibits your child from transferring, assigning, or pledging their interest in the trust. It also prevents creditors — including a divorcing spouse — from attaching or garnishing trust assets.
Massachusetts recognizes spendthrift protections, making this an effective tool for families in the Commonwealth. Combined with discretionary distribution provisions, a spendthrift trust provides a robust layer of protection.
Incentive or Milestone-Based Trust
You can also use a trust to control how your children spend their inheritance by tying distributions to specific milestones — finishing a degree, reaching a certain age, maintaining employment, or other conditions you define.
This approach keeps the bulk of the inheritance in the trust until your child has demonstrated the maturity and stability to manage it wisely — and it keeps those assets outside the reach of anyone who might take advantage.
Protecting Minor Children: The Importance of Testamentary Trusts
If your children are minors, a testamentary trust — a trust created within your will or revocable trust that takes effect upon your death — is essential. Rather than leaving assets to your minor children directly (which would require a court-appointed conservator), the trust holds the funds under the management of a trustee you’ve chosen.
This keeps your ex-spouse from controlling the money. The trustee — not the custodial parent — makes distribution decisions based on the terms you’ve established. You can specify that funds be used for education, health care, extracurricular activities, and other defined purposes, while preventing the funds from being used for general household expenses that benefit your ex.
Choosing the right trustee is critical here. Many parents name a trusted family member, a close friend, or a professional trustee — someone who will manage the funds in the children’s best interests and won’t be influenced by the other parent’s wishes.
Don’t Forget Beneficiary Designations
Your will or trust controls many of your assets, but some of the most valuable ones pass outside of your estate plan entirely — through beneficiary designations. This includes life insurance policies, retirement accounts (IRAs, 401(k)s), bank accounts with payable-on-death designations, and investment accounts with transfer-on-death designations.
If your ex-spouse is still named as a beneficiary on any of these accounts, they will receive those assets regardless of what your will or trust says. Massachusetts law does revoke certain beneficiary designations to an ex-spouse upon divorce — but this protection doesn’t apply to all account types, and you should never rely on it.
After a divorce, review and update every beneficiary designation you have. If you want the proceeds to go into a trust for your children rather than to your children directly, the beneficiary designation should name the trust — not the individual child.
The Role of Your Divorce Decree
Your divorce settlement may include provisions about life insurance, retirement account divisions, and obligations to provide for your children. Make sure your estate plan doesn’t conflict with these obligations.
For example, if your divorce decree requires you to maintain a life insurance policy for the benefit of your children, you can still name a trust as the policy beneficiary rather than naming the children directly. This satisfies the obligation while keeping the funds protected from your ex-spouse’s influence.
What About Blended Families?
If you’ve remarried and have children from both your current and prior marriages, the planning becomes even more complex. You’ll need to balance the needs and rights of your current spouse with your desire to protect assets for children from a previous relationship.
We address this topic in depth in our article on how to structure inheritance for a blended family in Massachusetts, but the short version is: trusts are essential. Without them, Massachusetts’s elective share and intestacy laws could redirect assets in ways you never intended.
Coordinate Your Plan with an Attorney Who Understands the Full Picture
Estate planning after a divorce requires more than updating a name on a document. It requires rethinking your entire plan — your beneficiary designations, your trust structures, your powers of attorney, your health care proxy — to make sure every piece reflects your current wishes and protects against unintended outcomes.
At The Law Offices of Kimberly Butler Rainen, we help families throughout Massachusetts create estate plans that account for the realities of divorce, blended families, and complex family dynamics. Your children deserve to inherit what you’ve built — and only what you’ve built should reach them.
