While it may look simple, the drafting of a will and other estate planning is actually very complex. State laws regarding estate planning change often, and failure to comply can make any changes illegal. An attorney with experience in estate planning can help you to avoid making a costly mistake, and keep you up to date on changes in estate law.
Remember: an improperly prepared will is invalid, and can create court battles and expenses that can eat away at the assets you spent a lifetime assembling. It is much better to safeguard your assets by consulting an attorney before beginning the writing of a will.
