Wasn't sure where to post this, but figured enough lawyers were around here to ask.

I am a professional musician, which includes composing new original works that are copyrighted and published. It was recently suggested to me that I needed to revise my estate planning documents to account for the complexities of owning copyrights and a music publishing company. This is new territory, so I'm seeking advice.

A few questions:

• Do I need to designate an heir for copyright ownership?
• Do I need to designate an heir for my publishing company and/or publishing rights?
• Can/should I specify my copyrights and publishing rights should be sold to another publishing company?
• Anything in particular I should consider that might not be obvious or otherwise apparent?
