Legal costs alone span a huge range depending on how much you and your spouse agree on. LegalZoom reports that the average cost of a divorce with attorneys is $11,300, with a median of $7,000. But those numbers mask the extremes: an uncontested divorce where both parties agree on everything can cost under $1,000 in attorney fees, while a contested divorce that goes to trial can exceed $20,000 — and in complex cases, much more.

According to DivorceNet, the national average hourly rate for family law attorneys in 2023 was $312, with California averaging $384 and New York $397. Attorneys typically require a retainer fee of several thousand dollars upfront, billed against hourly work. Court filing fees add another $100 to $435 depending on the state.

The degree of conflict is the biggest cost driver by far. When both spouses agree on property division, support, and custody, legal costs stay manageable. Each contested issue adds hours — and hours are expensive.

Affordability depends heavily on what income looks like after the split. Someone who was part of a dual-income household is typically managing on one salary going forward. For someone who wasn't employed — or was underemployed — that shift is even larger.

Research cited by Five Pines Wealth found that women's household income drops by an average of 41% after divorce, while men's falls by about 23%. Those aren't edge cases. They're typical. Oklahoma State University's Extension program notes that in most cases, the divorced person will be living on less money, and the non-working spouse in a single-income marriage may need to find employment since alimony is awarded less frequently now than in past decades.

This income picture — what reliably comes in each month — is the foundation for every other affordability question. Start there before you look at expenses.

One of the most common financial surprises in divorce is discovering just how much it costs to run two households instead of one. The expenses that seemed manageable when split between two people — rent, utilities, groceries, insurance — now fall entirely on each individual. Research from Smedley Law Group found that post-divorce expenses can run 50% to 75% higher than couples anticipate.

There's also the setup cost of a new household. Moving expenses, security deposits, utility connection fees, and furnishing a new space from scratch can easily reach several thousand dollars before a single recurring bill has been paid. These costs need to be in your planning picture before you separate — not discovered afterward.

Prudential advises mapping out the full housing scenario: what happens if you sell the house and what proceeds you'd receive, what happens if one spouse keeps it, and what your new housing cost will be in either case.

Your income tells you what's coming in going forward. Your liquid savings — checking, savings, and accessible accounts — tell you what you can absorb during the transition. Divorces don't conclude quickly. Legal processes take months. During that period, you may have both ongoing household expenses and attorney fees running simultaneously.

Knowing how much liquid cash you have, and how long it can cover your essential expenses and legal costs, is one of the most important calculations to do early. A family law attorney from The Carver Law Firm advises clients to treat a divorce like dissolving a business partnership and to have a clear-eyed picture of the financial runway before negotiations begin.

If your cash is thin relative to your expected legal costs and transition expenses, that's a planning gap — not a reason not to proceed, but something to address deliberately before you're in the middle of it.

If your financial plan depends heavily on receiving alimony, child support, or a specific settlement outcome, it's essential to understand that those are assumptions — not guarantees — until a court order or signed agreement makes them real. Support amounts are determined by state law, court discretion, and the facts of your specific situation. No planning tool can calculate them for you; only an attorney familiar with your state's rules can give you a realistic range.

U.S. Bank and other financial planners consistently advise building your post-divorce budget around the income you know you have, and treating support as supplemental — particularly because support arrangements can change over time and enforcement isn't automatic.

Build your financial picture with and without support in it. If the numbers only work when everything goes your way, that's important information before you sign anything.

Affording a divorce is a question with real answers — but only once you've built an honest picture of what the process will cost, what your post-divorce income will actually be, and how long your current cash can carry you through the transition. The goal isn't to frighten you into staying. It's to help you make the decision with your eyes open, and to plan for the financial realities that catch people unprepared. A sober look at the numbers now is far less painful than a surprise six months in.
