Lawyers and attorneys should understand the industry to which the the M&A is taking place so as to understand the pitfalls. Prior to any negotiations, investigative checks on the company as well as directors/shareholders should also be done.
M&A lawyers should have in the data system all encompassing legal DD check lists which can be initially drafted by lawyers using other check lists that have been used in the past by colleagues or by other M&A professionals. Lawyers should them review these lists and produce their own check lists from their own experience. Then when a specific transaction is to take place it should be reviewed and updated by the lawyer to include matters that may be specific to the such transaction and its industry. Such check lists should also be updated with the times and with new regulations that may be applicable form time to time.
