No lawyer can give you proper advice about the law anywhere other than the jurisdiction in which that lawyer is qualified to practice.
In the United Kingdom there are at least three different jurisdictions. England and Wales count as one jurisdiction together, and then Scotland and Northern Ireland have their own completely separate legal systems. That is without mentioning places like the Isle of Man and the Channel Islands, and so on.
We are a firm of lawyers qualified within England and Wales, and therefore we are only qualified to give advise in relation to the law of England and Wales. Very often also the 'Wales' is dropped. Sorry Wales. But whenever you see reference to the law of England or to a lawyer qualified in England, that almost invariably includes Wales as well.
Nevertheless there is some overlap between the laws of different jurisdictions. Because we are in the EU nowadays, English law includes a lot of law that comes from Brussels. So that counts as English law as well, but that still does not mean that an English lawyer is qualified to give you advice on the law in (say) France, just because France is also a member of the EU. For that you would have to consult a French lawyer.
So please be aware that your English lawyer will give you advice on English law only and not on any foreign law unless you specifically ask for it, and if you do ask for it you will probably be referred to another lawyer who has the necessary expertise to advise you about the foreign legal system in question.
