Re: Here's a question for your lawyers
I don't think any lawyer could answer your question with that little information and I strongly urge you to talk to one in person instead of over the internet. Having said that I am not going to give you advice but a couple of questions that might help you in preparing for your appointment:
* What is your nationality, what is your wife's?
* Where and when did you marry?
* Where do you live now and where does your wife live?
* Did you conclude any prenuptials (assuming those can be enforced in the jurisdiction your marriage is under)?
* When did you create the libraries and where?
* Were you employed at the time of creating the libraries? Were you a student? Were you self-employed? Did you own your own company?
* Did you generate income and did you eventually support your wife during the creation of the libraries?
* Do you use the libraries currently in order to generate income? E.g. by dual-licensing them or by using them in your own projects?
* Do others contribute (send patches, write documentation or translations)?
* Where does the valuation from the other side come from? Is it made up? Was there some expert advice? Was that advice correct (many so called IP valuations contain mistakes, e.g. they fail to consider the necessity (and the costs) of supporting of ongoing development)?
This list is of course not exhaustive and really: *TALK TO YOUR LAWYER*.
Please don't post any answers but feel free to use the questions. One word of advice: It feels like sh*t (thankfully I am not a family law lawyer) but at some point that dark tunnel ends. Really.
