Can a nieghbo claim property by mowing it?

In general, simply mowing a neighbor's property does not grant them a legal claim to it. Ownership disputes typically require more substantial actions, such as continuous and open use of the property for a specific period, known as adverse possession, which varies by jurisdiction. Mowing alone would likely not meet the necessary legal criteria for claiming ownership. It's always best to consult a property attorney for specific legal advice regarding such matters.
