I want a divorce but my husband doesn't. We have been living apart for almost 5 years. What should I do first in order to move forward.

we have been living apart for almost 5 years and I want a divorce without a hassel. My problem is he has control of all the financial records bank statements, stocks,etc. I know he will not give them to me because he doesn't want things to change. He owns his own business as well as several stocks and land. I found out he recently purchased some property in another county and also has taken 2,500 out of our checking account and put it into a bank near this other property. I think he is trying to hide funds so that I will not get them. My question is how do I get our financial records if he has them? Also, I am on a budget and do not have a lot of money to spend on a lawyer what is my best option? Please help, I just want out of this marriage. We have been married for 24 years, but not living together for the last 5. We have 2 teenage boys that he hardly pays attention to. I found out 5 years ago that he had a mistress for 10 years behind my back, I should have divorced then.
