A more thorough explanation:

A revival statute is a law that provides for the renewal of actions, wills, and the legal effect of documents. For example, if a will is not probated within a certain time frame, it may become invalid. However, a revival statute can renew the validity of the will if certain conditions are met.

Another example is a statute of limitations. If a person fails to file a lawsuit within the time limit set by the statute of limitations, the claim may be barred. However, a revival statute can renew the claim if certain conditions are met.

Overall, a revival statute allows for the renewal of legal actions or documents that may have become invalid due to the passage of time or other factors.
