90.06(1) (1) When any owner or occupant of land builds a fence before a boundary line has been located between that land and any adjoining land and the location of the boundary line establishes that the fence is located on the adjoining land, the person who built the fence or that person’s grantee, devisee or heirs shall be the owner of the fence. The owner of the fence shall relocate the fence to the boundary line within 30 days after service of written notice of the location of the fence upon the owner of the fence by the owner or occupant of the land upon which the fence is located.

90.06(2) (2) The notice under sub. (1) shall be served personally on the fence owner or by leaving a copy of the notice at the fence owner’s usual place of abode with some member of the fence owner’s family who is of suitable age and discretion.

90.07 90.07 Division of partition fence.

90.07(1) (1) A division of a partition fence, or the line upon which a partition fence between adjoining lands shall be built, may be made by fence viewers in the following cases:

90.07(1)(a) (a) When a division of a partition fence, or the line upon which a partition fence between adjoining lands shall be built, shall not have been made in the manner prescribed by s. 90.05, either of the owners of adjoining lands may have the line between that person’s land and the adjoining land of any other person divided, and the portion upon which the respective owners shall erect their share of the partition fence assigned, regardless of whether that person’s land be enclosed or not and regardless of whether such adjoining land be enclosed or not.

90.07(1)(b) (b) When any lands belonging to different persons in severalty shall have been occupied in common or without a partition fence between them and one of the occupants shall be desirous to occupy that occupant’s part in severalty, and the other shall refuse or neglect, on demand, to divide with the desiring occupant the line where the fence ought to be built or to build a sufficient fence on the part of the line belonging to the other occupant, when divided, the occupant desiring it may have the same divided and the share of each assigned.

90.07(1)(c) (c) When any controversy shall arise about the right of the respective occupants in partition fences or their obligation to maintain the same, either party may have the line divided and the share of each assigned.

90.07(2) (2) In either such case application may be made to 2 or more fence viewers of the town where the lands lie or to 2 or more fence viewers of 2 towns, if the lands lie in 2 towns, who, after 8 days’ notice in writing to each party to be served as a summons is in a civil action in a court of record or by registered mail with return receipt requested in the case of a party who does not reside in this state, shall, in writing, divide the partition fence or line and assign to each owner or occupant that party’s share thereof; and in each of said cases they shall also therein direct the time within which each party shall build or repair, as may be proper, that party’s share of the fence, having regard to the season of the year, and shall file such decision in the town clerk’s office, who shall record the same.

90.09(1) (1) When the boundary line between enclosed lands owned by different persons is a river, brook, pond or creek, which of itself is not a sufficient fence, and it is impracticable, without unreasonable expense, for a partition fence to be built on the true boundary line, and either owner or occupant refuses to join in making a partition fence on either side of the river, brook, pond or creek, or they disagree respecting making a partition fence, either party may apply to 2 or more fence viewers of the town, who, after giving notice as provided in s. 90.07, shall proceed to view the river, brook, pond or creek.

90.09(2) (2) If the fence viewers determine that the river, brook, pond or creek is not a sufficient fence and that it is impracticable, without unreasonable expense, to build a fence on the true boundary line, the fence viewers shall, in writing under their hands, determine how or on which side of the river, brook, pond or creek the fence shall be built or whether the fence shall be built partly on one side and partly on the other side. The fence viewers shall assign to each owner or occupant that owner’s or occupant’s share of the fence and the time within which the respective parties shall build the fence. The fence viewers shall file their determination in the office of the town clerk, who shall record the determination.

90.09(3) (3) If either party refuses or neglects to build that party’s part of the fence within the time assigned by the fence viewers, the other party may, after having completed his or her own part, build the other party’s part and recover the expense of building the other party’s part of the fence as provided under s. 90.11.

90.09(4) (4) If the fence viewers determine that it is impracticable, either from the formation of the banks of the river, brook, pond or creek or for any other reason, to maintain any fence along or near the boundary line, they shall give written notice to the parties of that determination.

90.11(1)(a) (a) Whenever any owner or occupant of land has built, repaired or rebuilt any fence, pursuant to the provisions of this chapter, that the adjoining owner or occupant has been lawfully directed by fence viewers to build, repair or rebuild but has failed to do within the time prescribed, the owner or occupant who built, repaired or rebuilt the fence may complain to any 2 or more fence viewers of the town.

90.11(1)(b) (b) The fence viewers complained to under par. (a) shall, after having given notice to the defaulting adjoining owner or occupant as provided in s. 90.07, examine the fence and ascertain the expense of building, repairing or rebuilding the fence.

The special charge shall be collected by the town treasurer with the other taxes in the town. Any special charge under this paragraph remaining unpaid shall be added to the list of delinquent taxes returned to the county treasurer. The county treasurer shall collect the delinquent special charge or sell the land as for delinquent taxes. All proceedings in relation to the sale of land for a delinquent special charge shall be the same in all respects as in the case of land sold for other delinquent taxes. Every county treasurer who shall collect or receive any moneys on account of delinquent charges under this subsection shall pay the moneys received to the treasurer of the proper town.

If the line has been previously divided, the owner or occupant of the newly enclosed land shall pay the value of the fence on the part of the line previously assigned to that owner or occupant. In either case, the value of the fence at the time shall be ascertained on the application of either adjoining owner or occupant as provided in s. 90.11, if the parties do not agree.

90.13(2) (2) If the responsible owner or occupant fails to pay the value for 60 days after the value has been ascertained and demand made, the proprietor of the fence may recover the value with the fence viewers’ fees and costs.

The rate of pay for the fees and expenses shall be set by the viewer’s city, village or town. The fees and expenses shall be paid equally by the parties to the controversy, and if any of them neglect to pay the same within 30 days after the services are performed, each fence viewer may recover from delinquent parties jointly double the amount of the fees and expenses. A fence viewer who neglects to perform his or her duties shall forfeit $5 and be liable to the injured party for damages. Fence viewers may administer oaths for purposes of this chapter.
