Does a revocable living trust have to be notarized every 5 years?
No, there is no such requirement.
Living trusts must be notarized when they are made and if they are later amended. But one of their beauties is low-maintenance.
While most authorities agree that it is a good idea to periodically review a living trust to be sure it accurately reflects the maker’s wishes and includes the property he or she currently owns, there is no need to have it notarized again unless some substantive changes are made to it.
