Mississippi Code Title 89. Real and Personal Property § 89-13-23

The person who built the party fence may remove it at pleasure, if the owner of the adjoining land will not pay his proportion thereof; and although the proprietor of any land may desire to retain any fence built by him on a line which divides his land from that of another person, as a private fence, yet that other person may adopt the same as a party fence by paying his proportion of the value thereof; and if the value cannot be agreed upon by the parties, the person desiring to adopt the fence may apply to a justice of the peace to appoint freeholders to assess the proportion that should be paid, as in other cases.
