I would be very surprised if the Magistrates did not consider imposing a custodial sentence, however having said that it is not inevitable. Because of the severity of the offence you may well be eligible for legal aid, dependent upon your household earnings, you should contact a local solicitor to confirm with them. If you are not eligible you would need to instruct someone privately if you were to be represented at Court, my department specialises in this area and we would be happy to assist, if you are interested in this then please feel free to call on 0333 999 7158. Because of the potential for a custodial sentence I heavily suggest that you are legally represented in your hearing to give you the best chance of avoiding a custodial sentence.
