If a person sets up a charitable trust, it is generally safe for them to believe their money will go to the appropriate beneficiary. However, there are some instances in which this simply is not possible. For instance, establishing a trust for an organization or institution that disbands or closes shortly before the trust goes into effect would make the trust technically impossible to execute. Similarly, if a trust puts money towards a particular cause, but that cause radically changes, it may not be possible to carry out the trust according to the document's language.
