try
Community Legal Advice or have a look at any insurance policies you have for any legal advice added to the policy. My car insurance policy with tesco has 24 hour legal advice which covers any legal advice on any private legal matter, most people think these advice lines only cover motoring!!! Also if you work for a large firm might be worth checking they dont offer something like this, i know my work offers it which isn't that well known in our company.
The CAB can be a nightmare to speak to on the phone, recently tried getting advice for a polish guy at work and spent hours trying to get through to them in my area. So might be easier to go in to your local center.
Anyway good luck
