Legal Question in Civil Litigation in Nevada

There are several details you neglect to mention here.

First, do you know the legal owner of the property? If you do, you cannot simply claim ownership because it has not been claimed by the person who has legal rights to the property. You might be able to if you make a good faith (genuine) effort to locate and notify the rightful owner where the property is. Lost property may not simply be deemed abandoned if the true owner is known to the holder.

Are you the owner of the establishment? That is who must make any claim for such property. The circumstances of the "abandonment" come into play here, as well.

If an effort is made to find the owner and let him/her know his/her property has been found, but there still is no move by such owner to claim it, then it may be treated as unclaimed property. There is an entire chapter of statutes in our state relating to such property: http://www.leg.state.nv.us/NRS/NRS-120A.html
