In a situation where a woman decides she wants to get pregnant and uses a known party as a sperm donor, and not through an anonymous sperm bank or through a licensed physician in a clinic, the father may in fact have legal rights to the child and unless you had an agreement ahead of time that sets forth what your legal relationships are. You may run the risk. If you're the father of the child, you may run the risk of being financially responsible for the child. And, if you're the mother of the child, you may run the risk that the father is gonna try and get involved with the child later on. So, my advice to you is make sure your legal rights are set forth before you get involved in this in a written agreement that sets forth what your expectations are and you'll eliminate that potential problem.
