A standard will works fine for a straightforward family. One marriage, shared children, no competing interests. But if you have remarried, have children from a prior relationship, or are raising stepchildren, a standard will is not just insufficient. It can actively work against you.
The problem is not that standard wills are poorly written. The problem is that they are designed for a family structure that does not match yours. And when the assumptions built into those documents meet the reality of a blended family, the gaps become expensive, painful, and sometimes irreversible.
Competing Interests in Blended Families
In a blended family, the interests of your current spouse and your children from a prior marriage are not automatically aligned.
- If you leave everything to your spouse, your children from a previous relationship may receive nothing.
- If your spouse remarries after your death, those assets could end up with someone else’s family entirely.
A standard will that says “everything to my spouse” trusts that your spouse will eventually pass those assets to your children. That trust may be misplaced. Your spouse has no legal obligation to leave anything to your children, and Massachusetts law does not create one.
This is not about bad intentions. Circumstances change. Your spouse may need those assets for their own care. They may remarry and create a new estate plan. They may face creditor claims or a lawsuit.
The result is the same: your children lose their inheritance.
Massachusetts Law Creates Additional Risks
Massachusetts has an elective share statute that allows a surviving spouse to claim a portion of the deceased spouse’s estate, regardless of what the will says.
Under M.G.L. c. 190B, § 2-202, a surviving spouse can elect to receive a share of the “augmented estate,” which includes assets the deceased spouse transferred during life.
If you planned to leave most of your assets to your children from a prior marriage, your current spouse can override that plan by exercising the elective share. A standard will does not address this. It simply distributes assets and hopes for the best.
Additionally, Massachusetts intestate succession law treats blended families differently from intact ones.
If you die without a will and your spouse has children from another relationship, your spouse receives only the first $100,000 plus half the balance. Your children share the rest. But stepchildren receive nothing.
Where Standard Wills Specifically Fail
- No protection after first death. A standard will distributes assets outright. Once your spouse receives those assets, they are your spouse’s to use, gift, or bequeath as they choose. There is no mechanism to ensure anything reaches your children.
- No trust structure. Without a trust, there is no way to provide for your spouse during their lifetime while preserving assets for your children after your spouse’s death. A trust can do both. A standard will cannot.
- No creditor protection. Assets distributed outright to your spouse become part of your spouse’s estate. If your spouse has creditors, faces a lawsuit, or goes through a future divorce, those assets are exposed.
- No control over timing. A standard will distributes assets immediately upon your death (after probate). For blended families, immediate distribution often creates conflict. A trust allows you to stage distributions, set conditions, and maintain oversight.
- No coordination with beneficiary designations. Many of your most valuable assets, such as retirement accounts, life insurance, and payable-on-death accounts, pass outside of your will through beneficiary designations. A standard will does not account for these, and if the designations conflict with the will, the designations win.
What Works Instead
Blended families need a combination of trusts, carefully drafted wills, and coordinated beneficiary designations. Here are the structures that actually protect everyone:
A QTIP trust (Qualified Terminable Interest Property trust). This allows you to provide income and support for your surviving spouse during their lifetime while ensuring that the remaining assets pass to your children after your spouse dies. Your spouse cannot change the ultimate beneficiaries. This is one of the most effective tools for balancing competing interests in a blended family.
A credit shelter trust (bypass trust). This trust shelters assets from the Massachusetts estate tax at the first spouse’s death. Because Massachusetts does not offer portability of the state estate tax exemption, failing to use a credit shelter trust means wasting the first spouse’s $2 million exemption. For a blended family with combined assets over $2 million, this oversight can cost tens of thousands of dollars in unnecessary taxes.
Separate trusts for children from prior relationships. Rather than leaving everything in one pot, creating separate trust shares for each group of children ensures that your biological children receive what you intend, without relying on your spouse’s goodwill or future planning.
Updated beneficiary designations. If you want your life insurance or retirement accounts to fund a trust for your children, the beneficiary designation must name the trust, not the individual child. Otherwise, the funds bypass your plan entirely.
The Estate Tax Factor
The Massachusetts estate tax applies to estates over $2 million, and the tax is calculated on the full estate, not just the excess. The federal exemption for 2026 is $15 million.
Because Massachusetts does not offer portability, married couples in blended families face a unique risk: if the first spouse’s exemption is wasted, the surviving spouse’s estate could face a significantly higher tax bill.
Proper trust planning preserves both exemptions and can save a blended family hundreds of thousands of dollars.
Have the Conversation Now
The most important step in estate planning for a blended family is not the legal document. It is the conversation. Talk to your spouse about your goals for your children. Talk to your children about what they should expect. Transparency now prevents conflict later.
