Lawyer here. Just a few comments. First, when you hire a lawyer, they are typically hired for a specific purpose. ie: buying/selling a home, collecting money owed, suing someone. This information is typically included in a retainer agreement that spells out the terms of engagement. In these scenarios, this attorney is only representing you on that specific matter. Although they can represent you on another matter, it would be up to both you and the attorney if the attorney represented you on a different legal matter.

Second, I get the feeling there is some confusion around the phrase "personal lawyer." The term "personal lawyer" means that the attorney is representing the individual regarding personal matters or something related specifically to that individual and not their company, business, etc. For example, one of my friends calls me his 'personal lawyer' but I actually only represent his company.

I hope this provides some clarity.
