MD does appear to have very narrow circumstances in which a parent's rights may be involuntarily terminated. These are:
Circumstances That Are Grounds for Termination of Parental RightsFamily Law
A petition for termination of parental rights shall be filed if:
• The child has been in an out-of-home placement for 15 of the most recent 22 months.
• A court finds that the child is an abandoned infant.
• A court finds that the parent has been convicted, in any State or any court of the United States, of:
» A crime of violence against a minor offspring of the parent, the child, or another parent of the child
» Aiding, abetting, conspiring, or soliciting to commit a crime described above
IF these circumstances do not exist, then a court may not have the authority to terminate the non-custodial parents' rights even if they would like to.
