High Net Worth Divorce: Property, Experts and What It Costs

A high net worth divorce follows the same law as any other, but the money makes the details expensive: which assets are marital, what a business or stock options are worth, and how each split is taxed. The first question is your state's property system. Nine states use community property, where marital property is generally split equally, and the rest divide it in a way the court finds fair, which isn't always half.

Asset	What gets argued	Expert often hired
A business one spouse owns or runs	Its value, and whether growth during the marriage is marital	Business valuation expert
Stock options and restricted stock	Which grants were earned during the marriage	Compensation or financial expert
Real estate	Value, and separate money used for the down payment	Appraiser
Retirement accounts and pensions	The marital part, and the order to divide it	Actuary; QDRO drafter
Inherited or premarital assets	Whether they stayed separate or were mixed in	Forensic accountant
Income for support	What a self-employed spouse really earns	Forensic accountant

The community property states are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin (IRS Publication 555). Each applies its own rules, and none of them is as simple as splitting the total in half.

Estimate the cost

High-asset divorces cost more mainly because of expert fees and the hours spent on discovery. Use the quotes you've been given.

The defaults are an example, not a typical case: 150 hours at $450 and $20,000 for appraisers and accountants, $87,500 in all. A settled case can cost much less; a trial with competing experts can cost far more.

Separate property and mixing

Property you owned before the marriage, and gifts or inheritances to you alone, are usually separate in every state. They can lose that status when they're mixed with marital money, such as depositing an inheritance into a joint account or using it to pay down the family home's mortgage. Tracing money back to its source is where forensic accountants earn their fees. A prenuptial or postnuptial agreement can change these rules if it's valid under your state's law.

Taxes in the settlement

• Transfers between spouses. Property transferred to a spouse, or to a former spouse incident to the divorce, generally isn't a taxable event (26 U.S.C. § 1041). The receiving spouse takes the original tax basis, so a stock worth $1 million with a $100,000 basis isn't worth the same as $1 million in cash.
• Alimony. For divorce or separation agreements signed after 2018, alimony isn't deductible by the payer or counted as income by the recipient for federal tax (IRS Topic 452). Older agreements follow the old rules unless changed.
• Retirement accounts. A 401(k) or pension is divided with a court order so the transfer isn't taxed as a withdrawal. See what a QDRO is.

Questions to ask your lawyer

1. Is our state community property or equitable distribution, and how does it treat business growth?
2. Which assets do you expect to be argued over as separate?
3. Which experts do we need, and can we share a neutral one?
4. What's the after-tax value of each asset in the proposed split?
5. How does our state handle child support when income is above the guideline cap?
