You are bidding against firms that can lose money for two quarters
The auction price in this category is set by advertisers with more patience than you, so pick the ground where that matters least.
Family law is one of the most expensive categories in search, and the reason is arithmetic. A single retained matter is worth enough that a well-funded firm can spend through a bad quarter and stay in. If you enter on the broadest terms with a small budget, you are choosing the fight where their advantage is largest.
Start where intent is narrow and volume is small. A term naming a matter type and a county will generally cost less per click and convert better than the head term, because the person typing it has already worked out what they need.
Decide up front what you will pay for a consultation that actually happens. Not a click, not a form. Work backward from what share of consultations become matters at your firm and what an average matter is worth to you. Those two numbers exist inside your practice management system.
Then hold the account to it. Any campaign that cannot be tied back to booked consultations is a hypothesis, and hypotheses do not get a permanent line in the budget.
