Selected cases

Ciani v. MacGrath, 481 Mass. 174 (2019)
"To the extent a surviving spouse's shares of the decedent's estate exceed $25,000, § 15 reduces his or her interest in the real property from outright ownership to a life estate."

"As a practical matter, § 15 is unwieldly and perplexing to apply in most instances. ... In addition, it is "woefully inadequate to satisfy modern notions of a decedent spouse's obligation to support the surviving spouse or modern notions of marital property," ..., and, although not visited in detail here, the history of the statute leaves no doubt that it is decidedly gendered.... In short, the statute is in desperate need of an update and we urge the Legislature to do so."
