How to handle a Lease Extension?

[J Greenspan]

Hello everyone,

I know this is probably a dumb question (sorry in advance), but how does it work if I used a RE/MAX real estate agent to find a tenant/prepare the original lease, and now the tenant wants to extend the current lease? Do I have to do so using the same real estate agent since the lease is technically "owned" by RE/MAX? I found a lease extension form online but it specifically states: "Use of this form by persons who are not members of the Texas Association of Realtors is not authorized" (of which I am not). If possible, I would prefer to not have to pay commission fees if it's something I can legally handle on my own without the use of a real estate agent.

Thanks!
