My honest advice would be to think twice about the degree.
If you want to learn software development, that's easy to do for free, plenty of MOOCs (free online courses) at places such as edX and Coursera, and the library will be stocked with books.
Your law office will probably have a tech dept right? Start hanging with them and ask questions. If they are shorthanded, offer to help. Do they do e-discovery? Lots of opportunities to learn about the IT world there.
If you really want to do another degree, why don't you wait and save for it? How much could you save a year? As a last option there is borrowing the money...
