A common dispute among neighbors is who owns, as well as who is responsible for maintaining the boundary fence between their properties. While Texas does not have a specific state statute, there have been court cases over the years that address this topic.
Generally, a landowner in Texas has no legal obligation to share in the costs or future maintenance of a fence built by his or her neighbor on the dividing property line, unless he or she has agreed to do so.
