What is a caveat?

usually a warning or a condition one should be aware of as in the latin phrase caveat emptor which means buyer beware!! and that is the full extent of my knowledge of latin In addition to the above, the term "caveat" refers to a challenge of the validity of a will after the decedent has died but before the will has been admitted to probate. It has the effect of forcing the matter into will contest litigation. ---- In the UK, a caveat is a restriction entered at the Probate Registry to prevent someone from taking out a grant of probate or grant of letters of administration. It is usually done where there is likely to be a dispute, e.g over the terms of a Will or over who should administer an intestate estate. It does not always lead to litigation - it simply prevents administration of the estate until the dispute is resolved, either by mediation, litigation or other agreement between the parties. A caveat needs to be renewed regularly, and can be removed at any time by the person who registered it.
A warning of specific conditions or limitations.
