What is a key feature of gifts made to conceived and unborn children?

The key feature of gifts made to conceived and unborn children is that they are dependent on the birth of the child. This means that for the gift to be legally effective, the child must be born alive. If the child is never born, the gift cannot take effect. This condition highlights the unique legal status of gifts made in contemplation of the birth of a child, where the potential for the gift is entirely reliant on the event of birth occurring.

In this context, it’s important to understand that gifts are only recognized as valid once the child exists as a living person, which is why gifts that are intended for unborn children cannot legally transfer until the child is born. Other options do not apply to this specific context as each addresses different characteristics or implications regarding donor's tax or the nature of the gift itself.
