I notarized a lease agreement a few weeks ago. I made an entry of it in my notary journal and asked the signers to sign it.
The person managing the transaction asked me if it was necessary to keep a journal. I told him that Colorado law requires all notaries to keep a journal of notary acts that affect the title of real property. (CRS 12-55-111). However I keep a journal of all notarizations, regardless of what they pertain to.
The law has been amended to read that every Colorado notary will be required to keep a journal of every notarial act, and will go into effect July 1, 2009.
There are some other changes to the law. You can read about it at the Colorado Secretary of State website.
