Above the fold, say which of the three jurisdictions you actually file in
A visitor cannot use anything else on the page until they know the case can be handled where they live.
Put it in words a person reads without effort: we handle divorce and custody matters in the District, in Montgomery and Prince George's Counties, and in Arlington, Alexandria and Fairfax County. Naming the specific places is the point. Serving the DMV means nothing to someone deciding whether to call, and it is also the phrase every competitor uses.
If your coverage is uneven, say that too. A firm that takes District and Maryland matters but not Virginia should say so on the first screen. The inquiries you lose were ones you would have declined, and the visitors you keep now trust the rest of the page.
Underneath, two more facts: what the first meeting costs and whether it happens by video. Both are among the first things a person wants and among the last things most firm sites disclose.
Then a phone number that is tappable and an inquiry form that is short. Not a chat bubble that opens over the copy before anyone has read a sentence.
