Garden prone to flooding and path collects pools of water due to not being level/no drainage

The path could be taken up and relayed, putting in some sort of drainage like ago drains seeing in into a soak away. The lawn well you may need some sort of trench along the neighbours side of your lawn, maybe a French drain to take away the water and filling the trench with stones. This maybe the way forward.

lift and relay path put field drains in for lawn

Take everything up an put it back level or with a slight slope to a drain that leads to a soke away depending on how the garden sits

The best option in my opinion is to use Ago drains along the path making sure that the new path is made with a run off leading into them, on top of this you will also need to connect the ago drains into a soak away to make sure that they do not just hold the water. I'd recommend that you make sure that who ever makes the soak away uses soak away crates instead of building it out of rubble. This will be a slightly more expensive way but would mean that there would be less of your garden dug up and the turf would be less likely to sink over time. As regards to the garden flooding the best way would be to use a french drain, they're in my opinion the best way to irrigate a domestic garden. The french drain would also have to be connected to a soak away. It's always difficult to advise on these sorts of things without actually having seen the garden but that would be my advice to you. Best of luck.

the path will need to be lifted,but before it is relaid there will have to be land drains put down under the lawn,depending on what is at the far end of your garden,ie. fields,empty ground or somebody"s garden will determen wether or not you will need a soakaway or not for the collected water to run into,if done properly you should"nt have any more trouble.

Reading the description you give of the problem it seems that the water flooding your path and lawn comes mainly from the adjoined property, which is on a higher level. Regardless of any other intervention you want to do in your garden, you need to intercept the water coming from the other property. This can be done easily with low-cost drainage consisting of a drain pipe laid in a trench full of shingles and gravel running along the front from which the water comes. The trench, depending on its good looking or not, can be left exposed or covered. It can even be covered with turf after having laid a membrane to prevent soil clogging the gravel.
