Hello KSmith,
If your Lawyer is acting privately, it is not something you must worry about, as that is an issue between the solicitor and the Law firm.
We recommend you that, before requesting any type of service from him, you ask him for his Registration Number at the Colegio de Abogados, that is the equivalent to Bar of Association in Spain, and then check if that information is correct by contacting the corresponding Colegio, also asking if his registration is updated and if he is free of disciplinary sanctions. Most Colegios de Abogados have their own website including a database of registered lawyers, available for anyone to check. You can also make an enquiry over the telephone. I also recommend you to request a copy of his Liability insurance policy, that would cover damages in case professional malpractice. If your lawyer refuses to provide with the requested information and documentation, our advice is that you take precautions or just not hire him.
Regards,
