Legal Question in Family Law in Nevada

Despite your question being fairly fact specific, there is quite a bit of important information that is missing from your narrative that allows for an answer to be given that is fair to you. In reality, you are asking for what would be the final definitive result of a case you may have difficulty bringing in the first place, and where that case should be brought can't be determined by what you stated. Your case is way too complex, both factually and legally, to be able to fairly answer without detailed analysis. You should consult with a domestic relations attorney in your area. If you have some court order or there has been a written custodial determination(s) regarding your child, you should bring that to the consultation.

Roger is completely correct -- any meaningful answer will require a consultation with a family law specialist to go over an awful lot of facts about who did what, when, and where, and who has been where, for how long, before a decisive answer could be given.

In preparation, consider creating a timeline to explain those facts. A guideline for how to create a timeline is posted at http://willicklawgroup.com/consultation-policies/.

In the meantime, however, if you want to review the rules that govern the jurisdiction question (i.e., where you have to file to get what you are seeking), look at the article titled "The Basics of Family Law Jurisdiction," posted at http://willicklawgroup.com/child-custody-and-visitation/. That same web page has good deal of information that will help you about how the case would proceed if your case is heard in Nevada.

In the meantime, if you really believe that the child is in physical danger, you should contact Child Protective Services wherever the child is located.
