How to stop neighbors water rushing in my yard?

Put a barrier up we’re the water runs on your property something like a boarder we’re you put in garden but a little higher or a rock wall with stones you only need 2 high you could get the tan ones at Home Depot and stack them

look up how to install French drains, swells for water control.

Talk to your neighbor and see if you can find a solution together. Technically it is illegal to have run off from a neighboring property.

You might need to have your property professionally leveled to prevent your neighbor's water from running into your property.
