Deeds can have several dates on them. The date the document was signed, the date it was acknowledged, and the date the record was recorded. If there is a significant gap in the dates, try and determine why if possible. Acknowledgements were usually made before a notary or in open court–was it difficult for the signer of the deed to do this? If court was only held a few times a year, it might have taken a while before the signer was able to attend court.
If the date of recording is significantly after the other dates, did someone forget to record it? Did they wait until someone died to record the deed? It is possible that the grantor and grantee were deceased at the time the deed was recorded.
