When it comes to legal matters, the term "caveat to will" is not uncommon. This typically refers to a formal notice that is issued to a probate court to challenge or dispute the validity of a will. However, there are a number of other phrases and terms that can be used to convey a similar meaning. These include statements such as "objection to will", "contest of will", "will challenge", or simply "will dispute". No matter the terminology used, the purpose remains the same - to express disagreement or concern regarding the legitimacy of a last will and testament.
