Solemn Form

There are two kinds of probate; namely, probate in common form, and probate in solemn form. Probate in common form is granted in the registry, without any formal procedure in court, upon an ex parte application made by the executor. Probate in solemn form is in the natiu:e of a final decree pronounced in open court, all parties interested having been duly cited. The difference between the effect of probate in common form and probate in solemn form is, that probate iu common form is revocable, whereas probate in solemn form is irrevocable, as against all persons who have been cited to see the proceedings, or who can be proved to have been privy to those proceedings, except in the case where a will of subsequent date is discovered, in which case probate of an earlier will, though granted in solemn form, would be revoked.
