This action was commenced by Tracy and Sharon Baxter against their neighbors, James and Darlene Craney, to quiet title to certain real property. The district court granted summary judgment in favor of the Craneys upon the Baxters’ theories of title by adverse possession and title through boundary by agreement. After a trial before the court without a jury, the district court also found in favor of the Craneys and against the Baxters on a claim of easement by prescription. The district court then entered an order awarding attorney fees and costs to the Craneys as the prevailing party.
For reasons to follow, this Court affirms the order granting summary judgment on the adverse possession claim, but we vacate the order for judgment on the theory of boundary by agreement. We also affirm the judgment denying relief on the Baxters’ claim to an easement by prescription. Finally, we vacate the award of attorney fees and costs in favor of the Craneys, and we remand the action for further proceedings.
FACTUAL AND PROCEDURAL BACKGROUND
Tracy and Sharon Baxter and James and Darlene Craney are ranchers who own adjacent parcels of real property in Bear Lake County. The Craneys and the Baxters share a common boundary of approximately one-quarter mile in length. The Craneys purchased their land in 1996 and subsequently removed a portion of a fence located between the two properties. The Baxters contend that the fence marks the actual boundary between the two parcels. The Craneys, on the other hand, contend that the fence was put up for convenience purposes and was only intended to keep cattle from wandering onto a portion of their land. They claim the range line to the east of the fence forms the boundary between the two properties as established by a number of surveys dating back to 1882.
The Baxters filed this action against the Craneys in November of 1997, claiming ownership of the land east of the fence but west of the range line under the doctrine of boundary by agreement or by adverse possession. The Baxters alternatively claimed a prescriptive easement to cross the land lying to the east of the fence for the purpose of reaching a spring to water their livestock. Later, the Baxters attempted to amend their complaint to join the Bureau of Land Management (BLM) as a defendant in the action, asserting that the BLM was an integral party. The district court, however, refused to allow the Baxters to add the BLM.
The district court granted summary judgment in favor of the Craneys on the issues of boundary by agreement and adverse possession. The court concluded that the Baxters failed to present genuine issues of material fact regarding the existence of a boundary agreement between Tracy Baxter and Grant Esterholdt, the Craneys’ predecessor in interest, or the payment of taxes as is required for adverse possession. A trial was held on the issue of whether the Baxters acquired a *169 prescriptive easement to use the land east of the fence for stock watering. The district court found that the Baxters failed to prove the elements required for a prescriptive easement and awarded costs and attorney fees to the Craneys.
ISSUES ON APPEAL
The Baxters raise the following issues on appeal:
1. Did the District Court properly exercise its discretion in denying the Baxters’ motion to amend their complaint to add the Bureau of Land Management as a party?
2. Did the District Court properly grant summary judgment dismissing the Baxters’ adverse possession claim?
3. Did the District Court properly grant summary judgment dismissing the Baxters’ claim of boundary by agreement?
4. Was the District Court’s denial of the Baxters’ prescriptive easement claim at trial based on substantial and competent evidence?
5. Did the District Court properly award attorney fees and costs to the Craneys?
ANALYSIS
A. Motion to Amend
A trial court’s decision to deny an amendment to pleadings is reviewed by this Court under an abuse of discretion standard.
See Cook v. State Dep’t of Transp.,
Rule 15(a) of the Idaho Rules of Civil Procedure provides that leave to amend a complaint “shall be freely given when justice so requires.”
Id. See also Cook,
The Baxters attempted to amend them complaint approximately five months after the original complaint had been filed and after the date for trial had been set. The district court concluded that given the amount of time and money the Craneys had expended in defending the action, “it would be unfairly prejudicial at this point to allow Plaintiffs the opportunity to add a new party and change the dynamics of the action as it now stands.” This illustrates that the district court recognized it had the discretion to allow or deny amendment of the complaint. Because Rule 15(a) requires the district court to allow amendments only when justice requires, the court’s decision to deny the amendment was both within the bounds of its discretion and within applicable legal standards. In addition, the district court displayed sound reasoning for its conclusion. As the court noted, the issues the Baxters sought to resolve with the BLM were not directly related to their action against the Craneys. The BLM was neither a necessary party, nor were the Baxters unduly prejudiced by the district court’s refusal to allow the Baxters to amend their complaint, as the Baxters are not precluded from bringing a separate action against the BLM. Moreover, the potential likelihood of removal to federal court upon the addition of the federal agency *170 to the action would result in the Craneys expending more time and money so that issues unrelated to their case could be resolved. Accordingly, this Court holds that the district court did not abuse its discretion when it refused to allow the Baxters to amend their complaint by adding the BLM as a party defendant.
B. Summary Judgment Motion
1. Standard of Review
In an appeal from an order granting summary judgment, this Court’s standard of review is the same as the standard used by the district court in passing upon a motion for summary judgment.
See McDonald v. Paine,
2. Adverse Possession
Idaho Code section 5-210 defines the elements of adverse possession under an oral claim of right. The statute provides as follows:
For the purpose of constituting an adverse possession, by a person claiming title not founded upon a written instrument, judgment or decree, land is deemed to have been possessed and occupied in the following cases only:
1. Where it has been protected by a substantial inclosure.
2. Where it has been usually cultivated or improved.
Provided, however, that in no case shall adverse possession be considered established under the provisions of any sections of this code unless it shall be shown that the land has been occupied and claimed for a period of five (5) years continuously, and the party or persons, their predecessors and grantors, have paid all the taxes, state, county or municipal, which have been levied and assessed upon such land according to law.
The burden of showing all of the essential elements of adverse possession is upon the party seeking title thereunder and every element of adverse possession must be proved with clear and satisfactory evidence.
See Lindgren v. Martin,
The Baxters argue that they presented a genuine issue of material fact supporting their claim of adverse possession concerning the property, including the payment of taxes on the disputed parcel. The Craneys, on the other hand, assert that the Baxters failed to fulfill the necessary requirements to establish an adverse use of the land, and in particular, that there is no evidence that they paid the taxes on the disputed property.
Generally, Idaho Code section 5-210 requires actual payment of the taxes that are assessed with regard to the disputed property.
See Trappett v. Davis,
The Baxters argue that the “lot number” exception to the tax requirement applies in this case. The lot number exception states that:
(I)n the case of boundary disputes between contiguous landowners, where one landowner can establish continuous open, notorious and hostile possession of an adjoining strip of his neighbor’s land, and taxes are assessed by lot number or by government survey designation, rather than by metes and bounds description, payment of taxes on the lot within which the disputed tract is enclosed satisfies the tax payment requirement of the ... statute.
Scott v. Gubler,
This argument, however, ignores the rationale behind the lot number exception. As the Court stated in
Flynn v. Allison,
“[t]he primary reason behind the lot number exception is as follows: when taxes are assessed according to some generic description, ‘it (is) impossible to determine from the tax assessment record the precise quantum of property being assessed----’”
3. Boundary by Agreement
The doctrine of boundary by agreement has long been established in Idaho law. To have a boundary by agreement, the location of the true boundary line must be uncertain or disputed and there must be a subsequent agreement fixing the boundary.
See Cameron v. Neal,
In support of their argument, the Baxters rely in paid; on Tracy Baxter’s affidavit. In the affidavit, Baxter relates two separate conversations with Esterholdt — one in 1991 and another in 1992 — where Esterholdt purportedly acknowledged that the fence line constituted the boundary between their properties. When examining Baxter’s affidavit, however, the district court noted that it was “uncomfortable giving serious credibility to portions of Mr. Baxter’s affidavit given their hearsay nature.”
The Baxters also offered the affidavits of Marcia Singleton, who is Esterholdt’s daughter, and Henry and Lee Rigby, whose father owned the Craneys’ land at one time. Each of these affidavits to some degree supports the Baxters’ contention that the fence line constituted the boundary between the two parcels. Singleton states that her father considered the fence to be the boundary. She also states that she assumed that the fence line was the boundary. The Rigbys, on the other hand, both state that the fence was not constructed for convenience purposes, but was instead treated as a boundary between the two properties. ■ The district court, however, again commented on the affidavits, stating that it could not “in good conscience give [them] a great deal of credibility.”
We conclude that the district court erred by considering the credibility of the affidavits. Although affidavits must set forth facts that would be admissible as evidence,
see
I.R.C.P. Rule 56(e), it is not proper for the trial judge to assess the credibility of an affiant at the summary judgment stage when credibility can be tested in court before the trier of fact.
See Hines v. Hines,
C. Prescriptive Easement Claim at Trial
1. Standard of Review
Appellate review of the lower court’s decision is limited to ascertaining whether the evidence supports the findings of fact, and whether the findings of fact support the conclusions of law.
See Conley v. Whittlesey,
2. Prescriptive Easement
In order to establish a private prescriptive easement, a claimant must present reasonably clear and convincing proof of open, notorious, continuous, and uninterrupted use under a claim of right and with the knowledge of the owner of the servient tenement for the prescriptive period of five years.
See
I.C. § 5-203;
West v. Smith,
The Baxters argue that Esterholdt, the Craneys’ predecessor in interest, had actual knowledge that the Baxters’ cattle used trails on land east of the fence to reach the spring for water. The district court, however, noting that there was conflicting testimony that the trails were also used by deer and elk wandering off the BLM lands, concluded that the Baxters failed to provide clear and convincing evidence that the trails were sufficient to put Esterholdt on notice of their use as a means for the Baxters’ cattle to get to the spring. We agree. An examination of the record establishes that the district court’s characterization of the land is accurate. The land in question is essentially a knoll or hill. There are a number of trails present on the hillside, all of which could either be used by the Baxters’ cattle or by wild game. The Baxters argue that their testimony at trial delineated the main trails used by their cattle to reach the spring. The record, however, indicates that Esterholdt was ill and was only able to visit the property two or three times per year. Because a landowner need only maintain reasonable supervision over his property,
see Kaupp,
In addition, the multiple paths do not show any established right of way on a specific trail. As the Court of Appeals noted in
Roberts v. Swim,
an easement by prescription “requires a showing by the claimant of a line of travel without material change or variation.”
The Baxters alternatively argue that there is no evidence demonstrating how the fence line that separates the two parcels was altered to allow them cattle to reach the spring. They assert that the lack of evidence as to how the use of the disputed property began raises the presumption of open, notorious, and continued use for the statutory period in their favor under I.C. § 5-203, and contend that the burden then shifts to the Craneys, as owners of the property, to show that the use was permissive.
See West v. Smith,
Although it appears reasonable to assume that Baxter himself altered the fence to allow his cattle to reach the spring, it is true that the record does not indicate how or when the fence was moved. There are, however, facts suggesting that even if Esterholdt was aware that the Baxters’ cattle
*174
were crossing his land to water at the spring, their use of his property was permissive. The property in question is essentially useless for grazing because of its steep terrain and lack of vegetation. Additionally, Esterholdt did not lose access to the spring when the fence was moved. It is therefore logical to assume that even if Esterholdt was on notice that the Baxters’ cattle were crossing his land to reach the spring, he was simply being neighborly by allowing the fence to be moved and giving the Baxters’ cattle access to water. Because a prescriptive right cannot be established where the use was permissive,
see Hunter v. Shields,
The Baxters also contend that the Craneys took possession of the land with knowledge of the easement. As evidence of their knowledge, the Baxters point to testimony that the Craneys inspected the land prior to their purchase and observed the trails. An examination of the relevant testimony in the record, however, merely establishes that the Craneys were aware of the trails at the time of purchase. The Craneys’ mere appreciation of the abundant trails, without more, is insufficient to establish that the Craneys were put on notice of a prescriptive easement across their land. Accordingly, because the district court’s decision is supported by substantial and competent, although conflicting, evidence, this Court will not disturb its conclusion.
See Hunter,
D. Attorney Fees
Finally, we turn to whether the district court erred in awarding attorney fees and costs to the Craneys as claimed by the Baxters in this appeal. Because we remand the case for further proceedings on the question of boundary by agreement, we vacate the award and direct the district court to redetermine the issue of the award of fees and costs upon completion of the proceedings on remand. Nonetheless, we deem it appropriate to address an apparent misperception articulated by the district court with respect to its initial attorney fee determination.
The Craneys requested, and the district court approved, attorney fees pursuant to I.C. § 12-120 together with other costs pursuant to Rule 54(d)(1)(D) of the Idaho Rules of Civil Procedure. The district court noted that both the Baxters and the Craneys are engaged in the businesses of ranching and farming, characterizing each party as being involved in a commercial endeavor. The district court, however, also summarily concluded that the relationship between the two parties was of a commercial nature. This simply is not the case. Idaho Code section 12-120(3) provides that attorney fees may be recovered by the prevailing party in a civil action to recover on “any commercial transaction.”
Id.
The term “commercial transaction,” as defined in I.C. § 12-120(3), includes all transactions except transactions for personal or household purposes.
See id.
This Court has previously recognized that “[a]ttomey fees are not appropriate under I.C. § 12-120(3) unless the commercial transaction is integral to the claim, and constitutes the basis upon which the party is attempting to recover.”
Brower v. E.I. DuPont DeNemours & Co.,
The present ease is analogous to others decided by this Court and the Court of Appeals involving the determination of property rights.
See Jerry J. Joseph C.L.U. Ins. Assoc. v. Vaught,
E. Conclusion
The order of the district court dismissing the Baxters’ claims to title by adverse possession is affirmed, as is the judgment of the district court denying the Baxters’ claim to an easement by prescription. We vacate the district court’s grant of summary judgment dismissing the Baxters’ boundary by agreement claim and remand the case to the district court for further proceedings consistent with this opinion.
We also vacate the order awarding attorney fees and costs to the Craneys, and direct the district court to redetermine the question of the award of attorney fees and costs upon resolution of the claim of boundary by agreement.
No attorney fees or costs are awarded on appeal.
Notes
. The
Trappett
Court notes that "a good deal of the judicial gloss has evolved mechanically and without benefit of supporting rationale, a criticism which might well be leveled at the tax payment requirement itself.”
