No. A membership record simply indicates that a person is a child of his or her parents. As a clerk is creating membership records for children, the questions ask something like "is <Father> the biological or legal adoptive parent of <Child>?" and the same for the mother. So there is no distinction on the membership record.

When a child becomes a legal adult (which I imagine varies from country to country), the child then has rights (within Church policies and the laws of the land) to make changes such as legal name. Until then, the parents are the legal guardians and would have those rights.

Because of the previous responses, this question is somewhat irrelevant -- the adoption information is not on the record.
But in general, members don't ever see their actual membership records. They may see their Individual Ordinance Summary, which contains much of the information on the membership record. But again, parents of minor children would be responsible for making decisions in this area. Once a person becomes a legal adult, he or she has every right to see the IOS.
Questions that can benefit the larger community should be asked in a public forum, not a private message.
