I recently helped a client get probate for her mother’s estate. The will had been done years earlier, and unknown to everyone involved, the pages were accidentally misnumbered to be missing one number – so while there were no pages missing, it appeared that page 5 was not there. Thankfully, we were able to get the lawyer who drafted it to sign an affidavit that there was no page 5 and it was simply a typo, and were able to get probate for the estate.
We all make mistakes; none of us is immune. For minor errors like this, it is often possible to explain the situation to the court and have probate approved. If there are more serious errors, it may require a formal hearing to address the issue. Either way, just because there is an error is not fatal to a will.
