When buying via attorney, what roles do they perform?

[Samuel Hall]

When you hire an attorney for a transaction (Instead of using an agent, or yourself) what roles are they expected to perform?

For example:

Do they coordinate with the title company, and other associated vendors?

Do they draft all documents and all revisions?

I have little frame of reference and am learning how to operate most effectively while covering all of my bases legally. In my current transaction, if I am unable to contact my hired attorney in a timely matter I end up handling the time sensitive components myself including the drafting of documents.
