Selected cases

Adoption of Marlene , 443 Mass. 494 (2005)
Supreme Judicial Court held: "We conclude that a parent's consent to adoption of his or her child under G.L. c. 210, § 2 , does not terminate the parental duty to support the child."

Bobblis v. Costa, 94 Mass. App. Ct. 264 (2018) Appeals court determined that child’s participation in U.S. Army Reserve Officer Training Corp program (ROTC) does not constitute entry into the military, thereby triggering emancipation for child support purposes.

Leavitt v. Restuccia, Mass. Appeals Court No. 20-P-119 (2021)
The judge’s calculation of child support pursuant to the guidelines was error, as he improperly included in the mother’s income the SSDI dependency benefit that the mother received on behalf of the child as a result of the father’s disability. The SSDI dependency benefit must be included in the income of the noncustodial disabled parent — here the father. … After calculating the presumptive support order, the disabled father is entitled to a dollar-for-dollar credit equal to the amount of the SSDI dependency benefit. … Put another way, the $39 dependency benefit must be included in the father’s gross income prior to calculation of child support and then deducted from the presumptive order."

L.W.K. v. E.R.C., 432 Mass. 438 (2000)
Explains the obligation for child support after the death of the paying parent.

Okoli v. Okoli , 81 Mass. App. Ct. 371 (2012)
A husband was required to pay child support for twins who "were conceived through in vitro fertilization (IVF) using donor sperm and donor eggs.." "even though he did not intend to be legally responsible for any child so created." He "was the legal father of the children because he consented to the artificial insemination of his wife."

Rosen v. Rosen , 90 Mass. App. Ct. 677 (2016)
Retroactive modification - equity. Lists the six elements that a child support payor must demonstrate in order to receive an "equitable credit against a child support arrearage."
