There is no key required to gain access to the courthouse. In today's litigious society, there is absolutely no guarantee that your Will or any other estate planning document that you prepare will not be challenged. Your estate is liable for the legal expenses necessary to defend your Will. If you think it is a possibility that your Will may be contested, please let your attorney know. There are several defense mechanisms that can be added to your Will and other estate planning documents to eliminate or minimize this risk.
