First and foremost, this is only a guideline as estate planning costs depend entirely on the complexity of work, time and experience necessary, and the geographic location where services are rendered. That being said, basic estate planning costs between $500 and $1,000. More complicated plans will run several thousand dollars. If you combine estate and business planning, you can expect between $5,000 and $10,000 in fees because there are several documents and entities that must be created. The more appropriate question is how much will it cost you if you don't plan for your estate or business. In Florida, it is presumed reasonable for attorneys' fees alone to be 3% of the gross estate in probate. This can total between $5,000 and $15,000 on basic estates. Moreover, no money can compensate you for the emotional expense associated with poor or no planning. Sadly, we see it often. The costs and risks of not planning far outweigh the investment.
