First, find out how often they practice in front of that judge and what percentage of their practice is family law. $3000 is a lot money and a good attorney tries to use their client's money wisely. Do they charge for phone calls and emails? Do they have their paralegals do some of the work to save you money? Can you negotiate a flat fee? Many attorneys accept payments after the retainer is used or will do the work for a flat fee. It's best to try to have a face to face free consultation, but you are out of state. Get a phone consult and see if your personality meshes with the attorney. Read Avvo reviews, too.

Lastly , I would want to know his/her plan on presenting evidence favorable to the judge.
