Answer to Question 1
There will be a variety of discovery tools that can be used, starting with interrogatories. If there is a financial affidavit required, you will need to both prepare one for your client, and review the one presented by the other party. You will ask for documentation with Requests for Production, perhaps request a QDRO to be ordered to identify pension rights, and prepare to depose both the spouse and perhaps other financial advisors, using a subpoena duces tecum to ensure they come with necessary documents. You can use a preprinted questionnaire to ensure that all possible assets are identified, and you will need to interview the client both for preparation of your responses and to determine if there are any suspected gaps in their responses. In some cases, it may be necessary to hire an investigator and/or forensic accountant to review all the information.
Answer to Question 2
We'd want to start with the question, What kind of error? Catherine must handle this assignment with the utmost care and professionalism. Failure to do so could mislead her attorney about the client's overall financial picture, resulting in poor strategic decisions. Her supervising attorney is ultimately responsible for the negligent actions of the law office staff. This attorney, as well as the entire firm, would suffer the consequences. If Catherine's attorney instructed her in a clear and understandable manner to perform standard procedures and she did so in a slipshod manner, and the attorney relied on her work, Catherine might be admonished, or, depending on the severity of the repercussions, possibly fired. On the other hand, if Catherine's attorney's assigned work beyond her area of knowledge, training, and experience, and he did not review her work before it was either sent out or relied upon, Catherine should not be found responsible. The young attorney would have committed malpractice and that would be handled by his firm. Catherine should not be held responsible if she completed the assigned task to the best of her ability and training, and had made the assigning attorney aware of what the scope of that ability and training was.
