You need to determine the capacity, powers and level of authority that seller(s) have as the person in charge.In CA, the court document which will best identify those powers is called 'Letters' however they may referred to by various names in other jurisdictions.With these Letters you can determine if court confirmation is avoidable or required.If required, many attorneys want to review your offer prior to his/her client (the PR) signing the agreement.
