Can a stepparent adopt if the biological parent has a mental illness in Massachusetts?

Yes, you can file a stepparent adoption in Massachusetts when the other biological parent has a mental illness. What matters is how the consent and abandonment provisions of M.G.L. c. 210 apply to your family's situation. The statutes in the information we work from do not address mental illness directly, so how a diagnosis affects your case is something to confirm with the Probate and Family Court clerk or an attorney.

What the law does focus on:

• Parental consent: M.G.L. c. 210 § 2 requires written consent from the lawful parents. If the other parent is willing and able to sign, consent is the usual route.
• Abandonment: M.G.L. c. 210 § 3 addresses abandonment. Massachusetts sets no fixed number of months. Abandonment depends on the parent's overall conduct, so the court looks at the whole picture rather than a calendar count.
• Child's consent: If your child is 12 or older, the child's written consent is also required under M.G.L. c. 210 § 2.

Common situations, and what to check:

• The parent is in the child's life and willing to consent: Consent is handled under M.G.L. c. 210 § 2. The clerk can tell you how the court wants signatures handled.
• The parent has been absent or out of contact: Abandonment under M.G.L. c. 210 § 3 turns on overall conduct, not a set period. Whether an illness plays any part in that analysis is a question for an attorney.
• The parent has a guardian, or you question their ability to understand and sign: This depends on the facts, and the data we rely on does not cover it. Speak with a Massachusetts family law attorney and the clerk about notice, who must sign, and any extra steps.
• The parent objects: A contested case turns on its specific facts. Get individual legal advice before you file.

Other points that apply to your case:

• Court: You file in the Probate and Family Court. The county clerk's office can answer procedural questions and confirm the filing fee.
• Residency: Massachusetts has no minimum residency period under M.G.L. c. 210 § 1.
• Home study: It is waived for stepparent adoptions
