A more thorough explanation:

A derivative conveyance is a type of secondary conveyance, which means it is a transfer of property rights that is based on a previous conveyance. This type of conveyance is also known as a derivative deed.

For example, if John sells his house to Jane, and then Jane sells the same house to Tom, the conveyance from Jane to Tom is a derivative conveyance because it is based on the previous conveyance from John to Jane.

Another example would be if a developer buys a large piece of land and then subdivides it into smaller lots to sell to individual buyers. The conveyances from the developer to the individual buyers would be derivative conveyances because they are based on the original conveyance from the developer.

These examples illustrate how a derivative conveyance is a transfer of property rights that is based on a previous conveyance. It is important to note that a derivative conveyance cannot exist without a primary conveyance, which is the original transfer of property rights.
