Lawn weed advice, is this bird's foot trefoil/lesser trefoil?
I would be grateful if someone could confirm the ID of this lawn weed. I help an older neighbour with her garden and her front lawn has a significant infestation of this weed, several large patches.
I've done some research and the most likely culprits are those named above but I would like a confirmation, if possible, as well as any experience in treating it.
It's very low growing with the tiny yellow flowers pictured. These pic's are taken at the edge of the lawn where it grows a bit taller.

Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
The back lawn is full of 'wild flowers' ... trefoil, clover, daisies, self heal, wild marjoram, violets etc etc etc ... we cut it nearly as often as we cut the front lawn, again on a medium height, and never use any treatments on it and none of the 'weeds' get out of hand.

If you're open to using chemicals, Weedol Lawn Weedkiller is an effective broad leaf weedkiller so will kill pretty much anything that isn't grass. They recommend you apply it once a year but, if like me you actively weed your lawn, you might only need it every 2-3 years if not less often than that. However, I wouldn't suggest using weedkiller while the plant is in flower in case it could harm bees.
I agree with Dove's comment about cutting lengths. Long grass blocks light which makes it harder for weeds to germinate. Longer grass can also better withstand dry summers and cold winters.

But I didn't want that crocus in that spot, so by definition it was a weed.
