Background
Sarah Minden and Stephen Wright were in a long-term romantic relationship from 2005 to 2020. In 2007, Wright moved into Minden’s West Roxbury home without paying rent, in exchange for helping with household responsibilities. Because Minden was too busy with work to manage her finances, she added Wright’s name to her Brookline Bank checking account — an account she had held since 1978 — so that he could pay household expenses on her behalf. Minden never authorized Wright to use the account for his own personal expenses, and Wright never asked.
Several years later, Minden discovered that her expenses had grown dramatically since Wright moved in. After confronting him in 2014, the parties agreed that Wright would pay his own personal expenses and half of their joint expenses going forward. Wright sent Minden an email claiming he had previously deposited approximately 470,000 to 500,000 Canadian dollars into the account — a figure Minden believed. He also executed wills in 2014 and 2017 naming Minden as his primary beneficiary, though the wills contained a condition: Minden would benefit only if the parties were still living together at his death.
When Wright moved out in 2020 and Minden retook control of her finances, she discovered the truth: Wright had charged his long-term care insurance, medical bills, plane tickets, and personal credit cards to the account while contributing “nothing ever.” Meanwhile, his personal assets had grown from approximately $500,000 to $1.5 million during the relationship. After a three-day bench trial in the Superior Court, the judge found for Minden on her unjust enrichment claim and awarded $137,516.41 in restitution — covering Wright’s personal expenses and his share of joint expenses from 2016 through 2020. With prejudgment interest and costs, total judgment was $185,980.10.
The Court’s Holding
The Massachusetts Appeals Court (Shin, Ditkoff & Tan, JJ.) affirmed in full. Reviewing factual findings under the clearly-erroneous standard, the court rejected both of Wright’s arguments on appeal.
Wright’s first argument was that Minden could have had no expectation that account funds remained exclusively hers because she voluntarily added him as a joint account holder. The court disagreed. Minden testified that her purpose was to enable Wright to manage her finances for her convenience — not to grant him an unrestricted license to pay his own expenses. The parties’ 2014 agreement, in which Wright acknowledged he was required to pay his personal expenses and half of joint expenses, confirmed that expectation. The trial judge was entitled to credit Minden’s testimony and the Appeals Court deferred to that credibility determination. The court distinguished cases involving inter vivos gift analysis in estate administration, noting that in those contexts different rules apply and even then the account structure is not conclusive.
Wright’s second argument was that the parties had agreed Minden would forgo reimbursement in exchange for being named the main beneficiary of his estate. The court rejected this as well. The trial judge found that Wright’s wills conditioned Minden’s inheritance on the parties’ still living together at the time of his death — a condition Minden did not know about when the wills were executed. Given that Wright’s wills offered no reliable security for Minden, the trial court’s finding that no waiver agreement had been formed was not clearly erroneous.
Key Takeaways
- Adding a partner to a bank account for financial management convenience does not authorize that partner to use the account for personal expenses; the parties’ intent — not the account’s legal form — controls the unjust enrichment analysis.
- Unjust enrichment turns on the “reasonable expectations of the parties,” an inquiry that appellate courts review deferentially: where the trial judge heard testimony and assessed credibility, the clearly-erroneous standard gives substantial weight to those findings.
- A conditional testamentary bequest (beneficiary inherits only if living with the testator at death) does not constitute meaningful consideration for a waiver of restitution claims, particularly where the beneficiary was unaware of the condition.
- Long-term cohabitation without marriage does not shield a partner from unjust enrichment liability; Massachusetts courts will look past the domestic context to the actual financial arrangements and the parties’ reasonable expectations.
- Joint bank account creation is routinely misread as evidence of shared financial intent; practitioners advising clients who share accounts with partners should document the purpose clearly, as intent at formation is often the decisive issue in later disputes.
Why It Matters
Minden v. Wright is a useful reminder for family and civil litigators that the financial entanglements of long-term cohabiting relationships — even non-marital ones — can give rise to enforceable restitution claims under Massachusetts law. When one partner covertly diverts a joint account to personal use while falsely claiming prior contributions, that conduct falls squarely within the reach of unjust enrichment doctrine, even without a written agreement.
The decision also highlights a recurring issue in cohabitation disputes: joint bank account status is frequently offered as evidence that the account holder consented to any and all withdrawals. The court’s analysis makes clear that the account’s legal form is less important than the purpose for which it was created and how the parties understood their arrangement. Attorneys counseling clients who share financial accounts with domestic partners should advise them to document that purpose clearly — because absent that documentation, the fact-finder will be left to reconstruct intent from emails, testimony, and financial statements, often years after the fact.
