A: If you're spouse has money then the court can order him/her to pay for your fees and costs, including attorney's fees. If neither you or your spouse have any money, then you can go to a self help center at court and ask for free help and a fee waiver. They are not lawyers, they will only help you fill out the forms, and normally there are a lot of people waiting in line. If your spouse has money, an attorney MAY file the paperwork with a fee waiver and ask the court to have your spouse pay your attorney's fees.
A: It depends what the date of separation was, or if there is a date of separation. Date of Separation is a specific definition whereby both parties exhibit an intent to divorce, and do not intend to continue with the marriage. Any property acquired during marriage is community property. Marriage is from the date of marriage to the date of separation.
A: the home you inherited was your separate property. When you converted that home to money, and used YOUR money to buy a home during marriage, then he has a claim that the home is community property, absent written agreement to the contrary. If you wanted to keep it separate, you could of made him sign a post nuptial agreement. If you are thinking about a divorce, then you should hire an attorney and get advice in person. I would need more facts to give you a clear answer.
