What Drives the Cost of a Family Law Case

Hourly billing, retainers and RCW 26.09.140

Family law is billed by the hour against a retainer, so the honest answer to what a case will cost is a range that depends almost entirely on how much is actually in dispute. Two divorces with identical assets and identical incomes can differ by a factor of ten depending on whether the parties can agree.

This estimator asks about the things that move the number: whether the parenting plan is contested, how complicated the finances are, how the other side behaves, whether experts such as a parenting evaluator or forensic accountant are needed, and whether you expect to settle or go to trial. It returns a range of hours and fees along with the factors driving it.

The single biggest lever is you

Across almost every case type, the largest cost difference is not the assets or the income. It is whether the matter resolves by agreement or is fought out in court. Cases that settle through negotiation, mediation or the collaborative process routinely cost a fraction of cases that reach a contested trial, and the outcomes are frequently similar. King County reinforces that: under Local Family Law Rule 16 the parties in almost every family law case must complete mediation or another form of alternative dispute resolution before trial, and the case schedule sets the trial date roughly ten to twelve months after filing. That is why this estimator shows you both figures side by side rather than a single number.

Why Your Real Number May Differ

Where estimates meet reality

  • How much the other party disputes, and how reasonable their counsel is, which neither you nor we control.

  • Whether new issues emerge mid-case, such as a hidden account, a relocation request or a safety concern.

  • Court scheduling. Contested trials in King County are set months out, and trial preparation is the largest single block of work in a litigated case.

  • Expert fees, which are billed by the expert directly and are not included in the figures shown here.

  • Court filing fees ($364 to file a dissolution in King County), service costs and copies, which are also separate.

  • Decisions you make as the case goes on. Every contested motion has a cost, and some are worth it while others are not.

Frequently Asked Questions

Attorney fees estimator

How much does a divorce cost in Washington?

It depends almost entirely on how much is contested. An agreed divorce where the parties settle everything is a fraction of the cost of a case with a disputed parenting plan or a business to value. Washington’s 90-day waiting period means even an agreed case takes at least three months. The estimator above gives a range for your circumstances.

Do you charge a retainer?

Yes. Family law matters are handled on an hourly basis against an initial retainer, with the scope and rates set out in a written fee agreement before any work begins.

Can I make my spouse pay my attorney fees?

Washington courts can order one spouse to contribute to the other’s fees under RCW 26.09.140 after considering the financial resources of both parties, and fees can also be awarded where a party has litigated unreasonably. It is discretionary and never guaranteed.

Is mediation cheaper than going to court?

Almost always, and substantially so. In King County it is also required: Local Family Law Rule 16 calls for mediation or another form of alternative dispute resolution before trial in nearly every family law case.

Is this estimate a quote?

No. It is a planning tool based on how similar matters usually run. Your actual fees and the scope of work would be set out in a written fee agreement after we have discussed your situation.
