You can do this! We're here for you.
I strongly recommend you prepare for your consultations by having:
a) a point form description of your situation (time married, number of kids, your estimated yearly income, his income, his alcoholism, etc)
b) a list of point form questions to ask. Brainstorm about anything and everything you're worried about, categorize and write down point form. Here are some examples:
*What is the process of legal separation and divorce (specific time frame and delays)?
*What is my state/province's tendency with regards to custody (sole with visitation, joint)?
*What is involved in obtaining supervised visitation given my partner's history of alcohol abuse?
*What will be my financial responsibilities with regards to this divorce (common debt, etc)?
*Can I get use of the family home by asking my spouse to leave?
*Will there be repercussions with regards to custody if *I* leave the family home with my child?
*What is your hourly rate?
*How would you approach a case like mine?
You can either jot down notes or record the consultation so you can review the tape afterward. By preparing like this, you can get the most out of every consultation and compare each lawyer.
