Are you regulated?
If a lawyer is regulated, they will have certain types of standards and protection in place, which you can look up in our types of lawyer section.
Do you have any professional insurance in place?
Asking this will help you find out whether you would be entitled to claim compensation if something went wrong. You may also want to ask if their insurance covers you if you find a problem with the outcome of the work and the law firm is no longer open.
Can you give me an idea of cost and are there additional costs outside of your quote?
Lawyers should be able to give you a cost estimate. You should also check if things like VAT, expenses or insurance are included. If you want a lawyer to pay a third party on your behalf (such as the Land Registry or Companies House), check whether the payment itself is included.
