How I can claim my share

Looks like a pretty big up hill battle - multi-international claim and no written contracts? What kind of proof do you have? Did you compile the code, did you leave any hidden signatures in the code?

After they denied to pay you (in writing? By phone? By email?), you should not have released the code. Essentially, you should have held out until you were paid.

So it may be too late.

However, how much of a paper or electronic trail have you got? Is it a bunch of phone calls? Time sheets? Letters? Emails? Email can be faked, but it may at least be demonstrative of a commercial relationship.

Also, even if there is no intellectual property law there, you can probably sue under good old fashioned contracts law. You contracted - even if not in writing (although that would help you prove your case) - to provide code in exchange for a consideration (payment).

This is indeed an uphill battle, but it's not an impossible one. So get your proofs lined up, and start looking for an attorney to represent your interests.

You live in Myanmar? Geez, you are so screwed. You don't need legal help, you need to get an exit visa.

Thanks for all replies,

I have a copy of letter, posted to University of Computer Studies Yangon(UCSY). It is the sole document that I have now. In this letter, I disagree to be presented my software at the juries of teachers from UCSY. In my code there is no signature of the evidence. I gave a CD with my all source code! That 15 students make their teacher believe that they have written all modules by themself. But my letter is posted their teacher just before the second time presentation at their university. First time presentation, I compiled it into binary.

Best Regards,
