A solicitor is a qualified legal professional who gives you expert legal advice for your situation. Solicitors usually practice in a certain field, e.g. Family law, criminal, commercial etc. and they may have areas of expertise in the field they practice in such as a family law solicitor having expertise in child issues. It is important to make sure you chose the right solicitor for your situation.
A solicitor will work with you directly to understand your case and situation so they can advise you accordingly on the legal action you may need to take and any issues you may face and how to resolve them. A solicitor will handle any paperwork from your case such as any forms you need to fill out and can handle any communications such as writing letters on your behalf.
If your case needs to go to court, your solicitor can represent you in court, but they may refer you to a barrister to represent you if the case is complex.
