Hi all,Could anyone tell me how to prune this tree

hi do you know which tree it is. its difficult to tell from your photo.

Hi sbg, sorry the smallest in the picture, the others are overgrown nettles and a selfset budlea. I tried to put 2 pictures up but the first disappeared when I went back to edit. Tech is beyond me.

Could it be a Young Indian Bean tree? I'm no good with Latin names sorry. I am using an ipad and I can make the picture bigger like using a mobile phone if you get my drift!

Very hard to advise without good identification. Could you take close up & picture of leaves?

I might have suggested a Judas Tree (Cercis) of some sort or another, just by the shape of the leaves, but hard to judge size.
