The short answer
An uncontested divorce in Las Vegas — where both parties agree on assets, custody, and support before filing — typically costs $1,500 to $4,000 in total attorney fees, sometimes less with a flat-fee document-preparation service. A contested divorce, where custody, property division, or support are disputed, generally runs $5,000 to $20,000+ per side, and a high-conflict case involving business valuation, custody litigation, or extensive discovery can climb well past $30,000.
Nevada's status as a community property state and a relatively fast residency requirement (six weeks) compared to other states shapes both the process and, indirectly, the cost — the paperwork itself is often simpler here than in many states, but that doesn't reduce cost when the underlying dispute is genuinely contested.
How retainers work
Most contested-divorce attorneys in Las Vegas require an upfront retainer — commonly $2,500 to $10,000 depending on case complexity — which is held in a trust account and billed against as work is performed, typically at an hourly rate of $250 to $500. When the retainer is drawn down, you're billed for a replenishment. This is the single biggest reason contested divorce costs are hard to predict upfront: the final bill depends heavily on how much your case actually requires, not a number either side controls entirely.
What actually drives a case from $3,000 to $30,000
Three factors explain almost all of the variance: whether custody is contested (custody disputes are consistently the most expensive part of a divorce, often requiring evaluations, mediation, and sometimes a custody evaluator), whether there's a business or significant asset requiring formal valuation, and how cooperative the other party's attorney is — a case can turn expensive quickly when one side uses procedural delay or excessive discovery requests as a strategy, regardless of how reasonable your own position is.
Flat fee vs. hourly — which to expect
Uncontested divorces and simple document preparation are increasingly offered at flat fees in Las Vegas, which gives cost certainty for straightforward cases. Contested divorces are almost always billed hourly against a retainer, because no attorney can predict at the outset how much litigation, negotiation, or court time a genuinely disputed case will require.
