I am not sugar coating anything here, take my word for what its worth to you. I graduated magna cum laude from my law school last May and did not get an attorney job until a few months ago. I make well below $50,000 a year in a relatively sized metropolitan area. I know people with top 1/4 in class + law review from my mediocre school who are currently unemployed and trying desperately to get contract attorney work for $18/hr. I will NOT sugar coat this for you! This is tough love.
Know what type of law you want the practice before you sit down in your first LS lecture. Job shadow attorneys in those areas. Do absolutely whatever is necessary to get any experience (this might require quitting your FT job and working PT as a law clerk to get actual legal experience; this is not what you want to hear but the reality is you will be competing with people from a swatch of schools around the country for these jobs and many will have some legal experience as law clerks). If your current job lets you, you need to keep that job long-term and work on the side. A JD is not an entitlement to paying work as an attorney, it only gives you a shot to take the bar exam. It is ultimately ALL on you to pass the bar exam, get legal experience, and work as an attorney in a way that does not result in disciplinary action from the Board of Law Examiners or termination/layoff from your employer.
Work very very very very very very hard during 1L. It will determine whether or not you can even work in certain firms or settings. Keep in mind that about 47% of all law graduates in 2013 and 2014 failed to get a job as attorneys. Thus, the struggle for work is REAL and you MUST do ALL you can to be on the other side of the coin-flip.
Given you are a part-timer I assume you are not at a super elite law school, and that is okay. 90% of all law students are not in the T6, despite what "conventional" wisdom on this subreddit and other law forums says. But you really need to minimize debt, especially since your husband is in grad school too. Do NOT end up taking out loans for food, drink, and song. I know students who were so overwhelmed in LS they just took out a "little extra" money to relax. Now they are part of the $150,000 + in debt crowd. It may seem ludicrous, but it is VERY easy to get way in over your head in debt.
Make sure you try writing on to law review after 1L. So many people say "yeah I worked so hard during 1L, screw that, hahaha." I know for a fact that the judges in the most rural parts of my pissant fly-over state discard ANY resume without law review on it--unless you do moot court and substantial other experience such as clerk in a DA/CA or PDs office.
Make connections with friends at law school. I refer some stuff to a few of my friends and they get $ that way. My area of practice is so closed-circuit that I really cannot benefit from them referring me anyone, but it could someday. The corollary to this: do not waste your time making friends with drama queens and party animals. They are jokers and not worth your time. EVERYONE drinks in law school, so get ready for that. However, most people DO NOT go out to a bar 6 nights a week and party. They are not serious and not worth your time getting involved in.
I was married during LS and I honestly skipped out on all of the "lets all go get wasted after LRW is turned in." I'd get home and read and so my homework until sat 9-10PM, then I would do stuff with my wife. I would not talk to her about my day. I would not bore her with my worries. It was a nice way to just escape for a while.
