The best way to get the right legal advice is to contact a Solicitor in your area.
The best way to do this is to search the website of the Law Society.
http://solicitors.lawsociety.org.ukYou will see loads of search criteria and refinement searches as you put in your details.
If you ring one of them and they can't help you then, I am sure they will give you the name of another suitable Solicitor in your area. However, before you ring them check their name also on the Law Society website to see if they are registered and see if they undertake the work that you require. See also if they have a website and what work they do.
I hope this helps. I am not a lawyer, but have used this route before on many occasions to find a specialist solicitor to do the work I required.
