When you build a cavity wall, bricks outside, concrete blocks inside,
do the mortar beds in the two leaf have to line up, e.g. with 2 bricks
to one block. Or is it OK for them not to, and the wall ties be at an
angle ?

Just watched my builders do this, bending wall ties to suit, my bricks are
imperial and blocks are metric so they are not going to match anyway in my
case

If the wall ties slope, wouldn't they encourage moisture to transfer
from one wall to the other?

As long as they are sloping towards the outside then all is OK.

They need to be similar, not exact, else you will have problems. an
inclch out is OK. This information is based entirley on building walls
for my own house, and learning from the screw ups.

The ties have "drips", as long as the drips are the lowest points,
then you shoule be ok. The ties I used have drips every 7mm or so,
some have one single drip, which may need more care.
