The Company that you mention, which is, I assume the same company as can be found at the link below, does have an A+ rating with the BBB. That said, the percent charge they want for whatever asset they have found is not insignificant. However, they often locate assets through their research that heirs of the deceased would never have found. So, if the heirs want any of the asset that they would not have discovered but for the company, they have to decide if some is better than nothing.As far as locating assets without using a company like this, it takes some footwork (on the computer) and sifting through old paperwork of the deceased.
