Legal Question in Family Law in Nevada

It depends. Can you trace the $54K to your separate property? If you are not sure, you should contact an attorney who can explain the distinction between community property and separate property.

John is correct. The law provides a method -- two, actually -- for distinguishing those interests; the first under a case called Malmquist, and the second under a a statutory amendment to NRS 125.150. Both are explained to some degree at http://willicklawgroup.com/property-rights-and-division/. But to analyze your specific facts, get all documentation of the transactions -- including any evidence of your intentions at any time, and most importantly all records of title, and see a family law specialist to explain what is important, what is not, and how it will probably come out.
