The given case is an example of open adoption.
Open adoption is a type of adoption where the biological and adoptive families have access to various levels of personal information about one another and can choose to get in touch. In contrast to open adoption, which is still a relatively recent phenomena in the west, many Asian communities, particularly those in South Asia, have long practised open adoption.
When a childless couple has little chance of having their own child, it is not uncommon in Hindu society, for instance, for them to adopt the second or later son of the husband's sibling. The individuals involved in the connection will determine exactly how an open adoption functions. In the majority of open adoptions, prospective birth parents and adoptive families communicate via phone calls, emails, and occasionally in-person visits to get to know one another before the child is placed.
After the adoption, the adoptive and birth parents can keep in touch via phone and email, picture and letter exchanges, and other mediums like text messages and video chats to maintain their relationship.
