Section 28 of the Hindu Adoptions and Maintenance Act, 1956, protects a dependent's right to maintenance, which is treated as a charge on the deceased's estate. This right can be enforced against a person who receives the property (a transferee). However, the right cannot be enforced against a "transferee for consideration and without notice of the right." This means the right *can* be enforced if either:
\[\begin{array}{rl} \bullet & \text{The transfer was gratuitous (a gift), regardless of whether the transferee had notice.} \\ \bullet & \text{The transferee had notice of the maintenance right, even if they paid for the property.} \\ \end{array}\]
Therefore, the right is enforceable in both situations (A) and (B).
