DNA

I don't want to expose anything here but mine was a multinational Airlines, a media corporation and a shopping site to name a few and after discussing for some time, i found that i would lose the names. so, i passed them to their owners quietly.
One way to check is to write to them saying you will think for it and don't reply. After some time, if they reply threatening with a court case with all procedures in a formal way, then u know that u should better return them in case of multinationals. I mean, unless your point is stronger, u r certain to lose the case.

telling lies about your strength of money and attorney are matters of joke and nothing else.
I suggest you hold the domain until they really inform you they are starting court procedures. Your positive point is you are in mexico.
