When selling my software, do I need to license it by law?

Question

Licenses for software and other works

When I sell my software, do I need to license it by law? Since, as I understand it, if there is no license, according to the law, this software turns out to be pirated (but I am the software developer, and I have the source code)

Answer 1

No. By law, copyright belongs to you by default, and moreover, is inalienable. So feel free to share)

Answer 2

See. The legal side to justify the use is an act of acceptance. And the agreement that precedes it, describing the process of transferring the software. In it, you can discuss both the transfer of binaries and exclusive rights to the source code. In addition, you can go to the patent and issue the rights to the software product, but this is in some cases when you need to assign the rights.
