This not really a bankruptcy question - you need the assistance of a divorce attorney. Bankruptcy does not really adjust your rights you may have in his pension.

I am an attorney, just not your attorney (yet). Any answers here are to be deemed informational unless and until you retain me as your attorney for actual legal services and legal advice. I offer free in-person consultations so feel free to contact me offline by email or phone. If you like my answer, please hit the thumbs up button.
You should retain a good domestic relations attorney to assist you in a fair and equitable division of assets and to explore what amount of maintenance may be appropriate, if any.
Nevada is a community property state. This means that everything acquired during the marriage, with very few exceptions (i.e. inheritence kept separate, peronal injury settlement kept separate) is presumed community property -- assets and debts -- and subject to EQUAL division. If you are able to dispose of your debts in the bankruptcy, all that will be left is dividing, equally, the assets and determining whether or not spousal support is appropriate. You need to consult with a divorce attorney in your geographic area, NOW, to ensure you are protecting your claims and understand the process.
Responses are for general information purposes only, and are based on the extremely limited facts given. A consultation with an attorney experienced in the area of law(s) indicated in the question is highly recommended. Information and advice given here should not be relied upon for any final action or decision, as the information is limited by its nature to the question asked and the fact(s) presented in that question. THIS RESPONSE DOES NOT CREATE AN ATTORNEY/CLIENT RELATIONSHIP, particularly considering that the names of the parties are unknown.
Your right to receive a portion of a spouse's pension will be determined by the divorce court. If you file bankruptcy, you must be sure to schedule this asset in your petition and claim an exemption to protect your interest. Hope this perspective helps!
