As an attorney (my practice is not family law, though) let me give you a few words of advice. Be sure to interview the attorney and get to know something about them - don't just choose one based on economics.
Be sure that he/she practices regularly in the court where you will be (the county)...because there is a definite edge for attorneys who are familiar with the judges.
Ask if he/she regularly represents husbands or wives and how many child custody cases they have handled.
Ask if he/she will regularly speak with you (and not relegate your calls to a paralegal or admin). Make sure that you have someone who will explain to you the proceedings and what is happening. You don't want to get to court and be surprised about something.
Ask if he/she can recommend a good mediator (always better to try this route even with an attorney representing you, because it is less costly both $$ and on the children's mental health).
Ask if he/she can give you the names of any clients they have represented....some attorneys have clients who will agree to speak to potential new clients (but not always, because there is issue of confidentiality).
Ask if he/she can refer you to any counseling or support groups. If he/she is interested in the overall well-being of a client, then it is likely that he/she will have some contacts to these type of groups (not just in it for the $$).
And finally, make sure you feel that he/she is someone you can trust and feel comfortable speaking to. I hope this helps you a little. Good luck. Email me anytime if you have questions or just need a little moral support. ____@____.com
