Questions & Answers about I och med att ägarbytet görs måste trafikförsäkringen börja gälla.
I och med att is a fixed expression that often means since, as, when, or once, depending on context.
In this sentence, it has the sense of:
- when / once the ownership transfer is made
- with a slight idea of because this happens, something else must happen
So it does not just locate the action in time; it also links it to the consequence in the main clause.
Because i och med att is a complete fixed conjunction used to introduce a clause.

- i och med
- noun phrase
= in connection with
- noun phrase
- i och med att
- clause
= since / when / given that
- clause
Here it is followed by a full clause:
- ägarbytet görs = the ownership transfer is made
So att is required as part of the conjunction.
