Legal Question in Family Law in Maryland

Re: Do siblings have rights to visit another sibling after adoption?

There is no automatic right to sibling visitation, nor is there any law which specifically authorizes visitation by siblings. However, you could file a court petition seeking it, and if a judge feels that it would be in the best interest of the child to maintain a relationship with her siblings, the judge could conceivably grant such rights.

Re: Do siblings have rights to visit another sibling after adoption?

Since your daughter was adopted by your step-mother and father, she is not legally considered a sibling of your other children, even though biologically she is. Unless the adoptive parents have very good reasons to keep the children apart, it is too bad to do so, but decisions about whom a child associates with are the legal right of the legal parents, and the chance of a court granting visitation rights to your other children are slim. If you have a strong argument about why it would be important for your daughter to visit with her biological siblings, you might file an action with the court and give it a try, but you will need a very compelling reason.
