As Real Estate Agents, we are only allowed to utilize the promulgated contract forms created for our designated states by our respective licensing agencies. A real estate agent cannot create specific forms which is considered practicing law and not legal. Also, providing forms from our state association of Realtors for public use is not authorized. I would check with the California Real Estate Commission for a form for public use, but I doubt if one will exist for room rentals.
You may check with a local office store for blank, fill-in forms that may fit your needs. Good Luck.... more
