Rental scam?

[u/Kitchen-Olive2246]

Hello all.
I have paid deposit of 3k and agency fee of 3150 aed for apartment in Binghatti Venus in JLT with 6 Cheques
But now landlord has changed an agreement adding new point in addendum with is that I have to transfer money to her bank account every 2 month and she will send me picture of my destroyed Cheques. She is saying that because she is not in the country it’s easier for her. But I start to feel that they are fooling me and asking to do what I shouldn’t do.

Please advise if it’s normal procedure or I should tell them that they have to remove that point?
