A separation forces a fixed set of decisions about property, support, children and debt, and the number you genuinely disagree on, not how angry you feel, sets the bill.
Before you call anybody, sit down with a legal pad and write out every decision the separation actually forces. Not the grievances, not the history, just the decisions: who keeps the house or whether it sells, what happens to the retirement accounts, whether support gets paid and for how long, where the children sleep on a Tuesday in March, and who carries the balance on the joint card. Most separations produce somewhere between eight and twenty such items. Some of them you already agree on, whether you have said so out loud or not. That gap between what feels contested and what is contested is where the money goes.
The inventory, in four buckets
Property comes first because it is the most countable. Real estate, vehicles, bank accounts, retirement plans, a business interest, the furniture nobody wants, the furniture both of you do. Support splits into two questions that lawyers price very differently: child support, which most states calculate from a formula with a small number of inputs, and spousal support, which is discretionary and can absorb billable hours the way a sponge absorbs water. Children means legal decision-making, the physical schedule, holidays, and how you handle a future move. Debt means the mortgage, the cards, the car notes, the student loans, and any tax liability sitting behind a joint return.
Write each item on its own line. Then mark it agreed, unclear, or contested. Be honest about the middle category, because unclear usually means neither of you has looked up the number yet, and once you do, the item resolves itself. A retirement account nobody has valued feels like a fight. A retirement account with a current statement in front of both of you is arithmetic. The work of turning unclear into agreed is cheap, often free, and it is the single highest-return hour you will spend on this.
Why the count, and not the anger, predicts the bill
Attorneys bill for the work that a disagreement generates, and a disagreement generates work in a predictable sequence: a letter, a call, an exchange of documents, a proposal, a counterproposal, and eventually a motion if none of that lands. Each contested line item runs its own version of that sequence. Two contested items is two sequences. Nine contested items is nine, and the sequences interfere with each other, because a concession on the house gets traded against the support number and the trade has to be priced twice.
Emotion changes how the process feels, not what it costs, at least not directly. Two people who cannot stand each other but agree on the schedule and the split of the accounts will finish faster and cheaper than two people who are perfectly civil and genuinely disagree about whether the business is marital property. What emotion does is inflate the count, by converting matters of fact into matters of principle. That is worth watching for in yourself, because every item you move off the contested list is a discrete, measurable amount of money you do not spend.
What each route actually costs you
With zero or one contested item, self-filed paperwork plus a single paid document review is usually the right shape. You pay the court's filing fee, which varies by county and is published on the clerk's website, and you pay one attorney for one or two hours to read what you drafted before you sign it. With two to four contested items and reasonably matched information, mediation does the work: a neutral, paid by the hour and split between you, walks the list and closes items one at a time.
Once the count climbs past four, or once a single item is large and opaque, such as a closely held business, a pension with a survivor election, or a house with a disputed down payment, hire representation and do it early. The point at which people most often regret waiting is the point at which they discover the other side already has a Divorce Lawyer and a filed proposal on the table. Coming in behind that costs more than starting alongside it, because you pay someone to reconstruct a record instead of building one.
Debt is the item people count wrong
A divorce decree divides responsibility between the two of you. It does not release either of you from a contract signed with a lender, which means a card in both names stays in both names until it is closed, refinanced, or paid off, no matter what the judgment says. The Consumer Financial Protection Bureau is the federal agency responsible for consumer credit reporting and lending practices, and the practical consequence is that your credit report keeps telling the truth about the account long after the court has finished. Pull a full report for yourself now. Every joint line on it is an inventory item, and the ones you can retire before filing shrink the count.
Do the inventory on paper before you make a single call, then take it into the consultation and ask the attorney to price the contested lines rather than the case as a whole. You will get a more useful answer, and you will know which parts you can carry yourself.
