How to change the bank account where the tenant pays the rent in the Czech Republic?

Q: What do you need to do if you want/need to change the bank account where the tenant pays the rent which is different than that written in the rental contract in the Czech Republic?

A: You simply need to sign the tenant a formal notification that the bank account has changed. It is not required by Czech law to need to sign any formal amendment to the contract when changing the bank account (though in practice sometimes it can be useful to do so in order to make the tenant feel more comfortable and provide a better paper trail).
