It is very difficult to get a divorce for a male in Nepal. Basically you have to wait for her to file a case. You can have your parents deal with court on your behalf by signing over in front of notary /people from embassy. Then case will be decided on court, where she will get her share from your property. It doesn't matter how much she is asking for it, eventually she will get what she is entitled legally but if you are in hurry then you will have to come in terms with her.
And for attorney, please ask someone backhome, and depending where in Nepal someone will be able to help you.

Nepal ko law (US ko pani same nai chha) heavily favors women.
