You need to send all required documents to support your application:

All is clearly stated in the Guide and Application form: proof of identity, original birth certificate, proof minimum of 12 months of ILR, proof of residence requirements (letters of employers, tax office), etc. But all depends on which basis are you applying (residence, crown service, marriage, etc).

I do suggest you use a checking service, a pending civil porceeding may well hamper your application, but the checking service will be able to advice you, otherwise ring them on 0845 010 5200 Mo-Fri 9:00 am to 9:00 pm.
