Make a full and honest disclosure to the lawyer of all the facts...good or bad. The lawyer will keep all facts in strictest confidence; and
Avoid unnecessary telephone calls to the lawyer.
You should consider the financial advantages or disadvantages of a proposed legal action by discussing it with the lawyer. For example, would the court costs and legal fees be more than the amount of a bad debt you would like to recover?
Get legal advice before signing documents or taking legal action, and then follow the advice of the lawyer.
