What's the strongest evidence you have of the date you started living there?
Hi Armoured! The first month was the hardest one. Basically not that much:
1) Tickets showing that on that day I arrived in the city from a long trip.
2) Many letters from friends who visited our apartment before and after I moved in stated that I moved in that month.
3) Letters from his parents who happened to visit us for 10 days during our first month of cohabitation. They started that they visited our flat multiple times during those 10 days.
4) Bank statements showing matching places such as Supermarkets, Restaurants, stores, bakeries in that district. For example, the same numbers of on each of ours statement over an over again. (it shows like Пятёрочка # 1234) I highlighted all the matching stuff.
5) Yandex.Taxi order history showing the rider to the flat (just one in that month tho)
6) WhatsApp convos like “when are you gonna be home? I’m cooking dinner”
In the second month I started to feel more comfortable with the new address so I had some online orders at pick up points near by our flat and food delivery.
By the time It gets more and more options like medical records, orders, many transfers, more friends who came over to our flat, and my family’s letters. But the first month is kinda “please believe us and our people’s statements”
