Plain-English Summary
When a probate court admits a will or refuses to admit it, Rule 108 requires that the notice mailed to heirs and legatees include a clear explanation of what rights they have as interested persons, using standard forms from the Article II Forms Appendix. Which form applies depends on whether the will was admitted or denied, and the same distinction carries through to notices sent by publication when mailing is not used.
The rule also covers foreign wills proved by copy, cases where a will executed outside Illinois is admitted here based on a copy rather than the original. Heirs and legatees in those cases get the same kind of rights explanation, whether the notice goes out by mail or publication.
