What to include in 3 Day Notice to Quit or Cure in Iowa

[Rebecca B.]

Here we go! First month's rent rent up front. Second month's rent paid on time. Third month an email to say it would be late. Paid four days late but they didn't pay the late fees. Fourth month was due yesterday. Not paid and no contact from them.

I want to serve them with a 3 day notice to quit or cure. I've found examples online but have a couple of questions.

1. Do I need to cite the legislation code that I'm using?

2. Can I include late fees?

3. I use Cozy for online payments. If they make a partial payment online will it negate the notice to quit?
