Co Signer Form and Information

[Kyle Doney]

I haven't had to do a co signer for any leases in the past. I found some co signer templates online, but wondering if anyone has one they could share that is solid? 

Also, do you put anything in the lease itself referring that there is a co signer or do you simply have the co signer form filed out? 

Any do and donts or other input appreciated.
