what are the procedures for divorce in nepal? Well, I am out of country and my wife is in Nepal. Is it mandatory, by law, for me to present physically in Nepal for the process of divorce?

No need to be physically present. Process is lengthy if husband initiated but if mutually agreed can be done quicker. I know of a lawyer who has done these in the past for people out of country let me know if you need contact info you can email him and find more info re: cost etc.

A friend of mine went through this and what Yuvaraj said sounds right.

के भयो तेस्तो र पापर्चुके लिनु पर्यो ? कि बिदेसमा गए पछी अर्की तरुनी (महिला) भेटिएकोले हो ? उहिले उहिले पहाड र काठ बात नेपाल सहर झर्ने हरुले श्रीमती संगै राख्न मन न पराउने भै गाउमा एउटा सहरमा एउटा श्रीमती बनाउथे रे ? कहिँ तेस्तै भएको त हैन ?just curious?

just an FYI the divorce procedings may go in favor of your wife in regards to spousal property claims as our law favors women. If you both have mutual agreement on property claims where the woman has decided not to pursue filing for it please make sure to officially document it. If you have already agreed to give out a portion of you property to settle a divorce still make sure the agreement is officially documented.  

 yuvaraj,
can you please message be the contact info of a lawyer you are talking of.

Thanks

 magorkhel, it's personal stuff dude. But still I would like to answer,
Jeevansaathiko(life partner) is the one who should be able to support in each and every situations no matter it's the tough one or the good one.
Mero dukka ko samayama maile usko saath paina,  and good time ma i prefer rather to be alone than her company.
If it was arrange marriage, I would have compromised but it was the love one...mesmerizing one...
yup we still do love each other but was never able to respect each other's feelings..so,  just need a break..

@pokhrelikanchi
I don't get your question. However, would like to say regarding that sentence.
My personal opinion only:
higher the expectation, deeper it hurts when the expectation scatters.
arranage marriage ma expectation, trust and even love, all starts after marriage,
love marriage ma it exists beforehand. 
so.......
