What can my mother-in-law do about the fact that her neighbors have closed off her gutter?

Questioner

My mother-in-law's neighbors had new gutters installed and they blocked my mother-in-law's drain by placing a plate so that all the rainwater no longer runs off via the neighbors' gutter and now everything overflows at my mother-in-law's. Talking to the neighbors is pointless, they just say that my mother-in-law's handyman is a bungler and that she should also get new gutters.

Lawyer

Your mother-in-law has the right to drain rainwater onto the property of the neighbours, which is an easement and therefore the neighbours may not deprive her of this right. They are liable for the work of their contractors. The neighbours must be summoned to make the easement possible at their expense.
