Amendment form for lease extension on my rental property?

[David Antunes]

I've got a rental unit in San Diego, CA with great tenants who are approaching the end of their current lease. They have told me that they are interested in renewing the lease, and I'm happy to have them stay.

I am preparing for the renewal and wondering if I can use the AMENDMENT OF EXISTING AGREEMENT form by the California Association of Realtors (C.A.R. Form AEA, 12/17) for this. Can I use one of these amendment forms to refer to the original lease and simply make adjustments on the monthly rent amount and the lease termination date?

Is there any risk in using the amendment form this way?

Thank you in advance!
