Estate Planning for Blended Families in Massachusetts — Avoid the Intestacy Trap

If you remarried and you have children from a prior relationship, Massachusetts default inheritance rules will almost certainly produce an outcome nobody in your family wants. Your surviving spouse will not receive everything. Your children from the first marriage may end up co-owning your home with your current spouse. And the resulting conflict can end in a forced sale and years of litigation.

This is not hypothetical. It is exactly what Massachusetts intestacy law dictates.

The Massachusetts Blended Family Intestacy Problem

Under M.G.L. c. 190B, § 2-102, when a married person dies without a will and has children who are not the surviving spouse's children, the spouse receives:

• The first $100,000, plus
• 50% of the remaining balance

The other 50% goes directly to the deceased's children.

If your estate consists primarily of a $600,000 home titled in your name, your surviving spouse gets $100,000 plus $250,000 (half of the remaining $500,000). Your children from your prior marriage receive $250,000. Since the home cannot be divided, your spouse and your children now co-own the property — and either side can petition the court to force a sale under M.G.L. c. 241.

Your spouse may be forced to sell the home they live in to pay out your children's share. Or your children may be forced to wait indefinitely while your spouse occupies property they partially own. Neither outcome is acceptable.

The Elective Share Adds Complexity

Even if you write a will leaving everything to your children and nothing to your spouse, Massachusetts law prevents that. Under M.G.L. c. 191, § 15, your surviving spouse can reject the will and claim the statutory elective share: the first $25,000 plus a life estate in one-third of the remaining estate.

The 2019 Cianci v. MacGrath ruling confirmed that a surviving spouse who claims a life estate under the elective share can petition the court to partition and sell the real estate. So even with a will, your spouse can force a sale of property you intended for your children.

Planning Tools That Actually Work

QTIP Trust (Qualified Terminable Interest Property). The QTIP trust is designed specifically for blended families. When you die, the home and other assets fund the trust. Your surviving spouse receives income from the trust and can live in the home for life. When the surviving spouse dies, the remaining trust assets pass to your children from the first marriage.

The QTIP trust satisfies the marital deduction (no estate tax at the first death) while ensuring your children ultimately receive the assets. The surviving spouse cannot change the remainder beneficiaries — your children's inheritance is locked in.

Life estate deed with special power of appointment. A simpler alternative: you deed the home to your children while reserving a life estate for yourself and, after your death, for your surviving spouse. Your spouse can live in the home for life, and the property automatically passes to your children when the spouse dies.

The risk: if your spouse needs long-term care, the life estate can complicate MassHealth eligibility. The five-year lookback period applies to life estate transfers.

Separate property ownership with a will. Keep the home titled solely in your name (not as tenants by the entirety) and use a will to leave it directly to your children. Your surviving spouse claims the elective share, but a separate life insurance policy payable to the spouse provides comparable financial security without tying up the real estate.

Common Mistakes in Blended Family Planning

Titling the home as joint tenants with right of survivorship. This means the home passes entirely to your current spouse at your death — your children from the first marriage receive nothing from that asset. If that is your intention, fine. But most remarried parents do not realize they are disinheriting their children.

Assuming beneficiary designations override the elective share. Retirement accounts and life insurance pass directly to named beneficiaries outside of probate. But the surviving spouse's elective share is calculated against the probate estate. If the probate estate is small (because most assets went to beneficiaries), the elective share may consume most of what remains.

Not updating estate documents after remarriage. Under M.G.L. c. 190B, § 2-301, if you marry after executing your will and never update it, your new spouse is automatically entitled to their full intestate share — even if the will leaves everything to your children. The omitted-spouse provision overrides your existing will.

Assuming your spouse will "do the right thing." Second marriages end at a higher rate than first marriages. Even if your current relationship is strong, your estate plan must account for the possibility that your spouse's priorities change after your death — especially if their own children or financial pressures enter the picture.

The Conversation That Prevents the Conflict

The most effective blended-family estate planning tool costs nothing: a family meeting where you explain your plan to your spouse and your children before you die. Transparency about who receives what — and why — prevents the shock and resentment that drive elective-share elections and partition lawsuits.
