Shop around. You should find a competent lawyer who will do it for around $100-$150.

If you can't afford that, Nolo press has a quite few good books about contracts, contractors, and IP rights. A visit to your library or bookstore, a few hours reading, plus some pocket change for a photocopy of the pages and you've got yourself a well-written contract ready to go.

I'm interested, how does this work? How do you prove the assets you use are the ones you have IP for? Do you have to list all the filenames, or descriptions of the content of every file? That would hardly seem watertight.

Is it possible to get an open-ended agreement that every piece of artwork sent to you and paid for (keeping records of payment per asset) automatically becomes your IP, rather than having to switch the IP after paying?

Depends on the situation.

With work for hire you can be extremely generic, just state that it is all works created or performed during employment.

For specific works, generally a very short description of the work or works is sufficient.

When contracting for works, you can state that it is for all works created as specified in the contract and subsequent amendments, agreements, work orders, and other attachments. (Or other wording as dictated by your lawyer.)



Enforcing IP violations is extremely time consuming and expensive. It very rarely happens. When a lawsuit does occur, it is usually obvious at the specific parties involved, and the specific works.



The big reason for doing it is that you cannot sell works that you do not own, and this assignment of rights says that you own it. It is a paper that is filed in a drawer and never seen again, like so many other rights assignments, but it must exist for legal purposes.
