OPINION
¶ 1 D.A. Osguthorpe and the D.A. Osgu-thorpe Family Partnership (collectively the Osguthorpes) appeal the- district court’s grant of Enoch Richard Smith’s motions for summary judgment and denial of the Osgu-thorpes’ motions for summary judgment, to dismiss, and to amend. We affirm in part, and reverse and remand in part.
BACKGROUND
¶ 2 Prior to 1966, Enoch Smith Jr. (Smith) 1 and D.A. Osguthorpe (Osguthorpe) were partners in a cattle and sheep business (the partnership). In November 1966, Smith and Osguthorpe entered into an agreement (the dissolution agreement) “to settle all of the rights between them in the partnership businesses and affairs.”
¶ 3 Under the dissolution agreement, Smith agreed to sell Osguthorpe his interest in the partnership assets, subject to a reservation by Smith of a share of proceeds derived from the sale or lease of property (the disputed property), which is the subject of this appeal. In return, Osguthorpe agreed to pay Smith $50,000 and to assume partnership obligations.
¶ 4 Smith and Osguthorpe signed the dissolution agreement. Additionally, Osgu-thorpe’s wife signed under a clause providing that “I ... agree that any interest that I may have in and to the [disputed property]
¶ 5 Sometime after entering into the dissolution agreement, Osguthorpe conveyed part of the disputed property to the D.A. Osgu-thorpe Family Partnership (the family partnership). The family partnership included Osguthorpe’s son Stephen.
¶ 6 On August 14, 1996, Osguthorpe and the family partnership entered into a twenty-eight-year agreement with Wolf Mountain Resorts, L.C. (Wolf Mountain) titled “Lease Agreement” (the lease). Under the lease, Wolf Mountain agreed to annually pay the Osguthorpes $100,000 to “lease[ ] ... specific portions” of the Osguthorpes’ property, including the disputed property, “for use as a commercial recreation area, including the installation, maintenance and operation of two ski lifts, snow making and clearing of ski trails and such other related facilities, structures and roads as may be required.” The lease also required Wolf Mountain to permit the Osguthorpes “to improve and to use” the property provided the Osguthorpes did “not interfere with ski lifts and similar structures and runs of’ Wolf Mountain.
¶ 7 Sometime in 1997, American Skiing Company (the Canyons) succeeded to Wolf Mountain’s interest in the lease. On July 28, 1997, the Canyons, Osguthorpe, the family partnership, and Stephen, as an individual, amended the lease. This first amendment granted the Canyons the right to construct a ski trail, and the right to repair and construct additional roads and relocate and upgrade lifts subject to the approval of Stephen and the Canyons’ director. The amendment required the Canyons to “include the Osgu-thorpes in their master planning process.” The amendment also increased the annual rent to $150,000.
¶8 On August 10, 1998, the lease was amended a second time. This second amendment gave the Canyons the right to have alpine skiing operations and to construct another road subject to the approval of Stephen and the Canyons’ director. The Osguthorpes retained the right to use and improve all of the property for their sheep and cattle ranching operations, so long as the same did not damage the Canyons’ facilities or unreasonably interfere with the Canyons’ winter use of the property. The amendment increased the annual payment to $200,000.
¶ 9 In November 1998, Enoch Richard Smith, as representative of Enoch Smith Jr.’s estate, brought a breach of contract action against the Osguthorpes, seeking a share of the lease payments. Smith filed a motion for partial summary judgment, contending the dissolution agreement entitled him to a share of the lease payments. The Osguthorpes filed a cross-motion for summary judgment, contending the dissolution agreement was unenforceable. Following a hearing, the district court granted Smith’s motion for partial summary judgment.
¶ 10 Thereafter, the Osguthorpes’ counsel withdrew and newly associated counsel filed a motion to reconsider the grant of partial summary judgment to Smith, asserting the dissolution agreement was unenforceable for want of consideration and under the statute of frauds. The Osguthorpes’ new counsel also filed a second motion to amend their answer to assert, inter alia, fraud defenses and counterclaims. The district court denied the Osguthorpes’ motion to reconsider, ruling that the dissolution agreement was integrated and satisfied the statute of frauds. The district court did not address the Osgu-thorpes’ motion to amend.
¶ 11 Smith filed a second motion for summary judgment seeking damages of one-half of the lease payments in excess of $1.60 per acre. In response, the Osguthorpes asserted the lease payments were mainly for services rendered by Osguthorpe and Stephen, thus a material issue of fact existed as to the allocation of payments due Smith. The district court granted Smith’s requested damages, concluding the lease payments were entirely for use of the disputed property not for services.
¶ 12 The Osguthorpes then filed a motion to dismiss for failure to join Stephen and the Canyons as indispensable parties. The district court refused to grant or deny the motion. Instead, the court ruled that although
¶ 13 The Osguthorpes now appeal the grant of Smith’s motions for summary judgment and the denial of their motions for summary judgment, to dismiss, and to amend their answer.
ISSUES AND STANDARDS OF REVIEW
¶ 14 The Osguthorpes argue the district court erred in granting Smith’s motions for summary judgment.
Summary judgment is appropriate only when there is no genuine issue as to any material fact and the moving party is entitled to judgment as a matter of law. In determining whether the [district] court correctly found that there was no genuine issue of material fact, we accept the facts and inferences in the light most favorable to the [nonmoving] party. In deciding whether the [district] court correctly granted judgment as a matter of law, we give no deference to the [district] court’s view of the law; we review it for correctness.
SME Indus., Inc. v. Thompson, Ventulett, Stainback & Assocs.,
¶ 15 The Osguthorpes also argue the district court erred in not ordering join-der of Stephen and the Canyons. We review the district court’s “rule 19 determination under an abuse of discretion standard.”
Grand County v. Rogers,
ANALYSIS
I. Is the Dissolution Agreement Enforceable?
¶ 16 The Osguthorpes raise a number of issues in contending the district court erred in enforcing the dissolution agreement. We consider each issue but conclude the district court did not err in concluding the dissolution agreement is enforceable.
A. Consideration of Parol Evidence in Determining the Dissolution Agreement is Integrated
¶ 17 The parol evidence rule “operates in the absence of fraud to exclude [prior and] contemporaneous conversations, statements, or representations offered for the purpose of varying or adding to the terms of an integrated contract.”
Union Bank v. Swenson,
¶ 18 “[A] court must first determine whether the writing was intended by the parties to be an integration. In resolving this preliminary question of fact, parol evidence, indeed any
relevant
evidence, is admissible.”
Union Bank,
¶ 19 The dissolution agreement provides that the parties “now desire to settle all of the rights between them.” (Emphasis added.) Further, the agreement requires Osgu-thorpe to pay $50,000 to Smith within thirty days of the date of the agreement and “upon payment in full” requires Smith to execute and deliver assignments, deeds, and bills of sale necessary to convey his interest in the partnership businesses. Each party also agrees to “release and discharge” the other from all claims arising out of the partnership. We conclude the unambiguous language establishes that the dissolution agreement is integrated.
B. Consideration for the Dissolution Agreement
¶20 Next, the Osguthorpes argue that although in the dissolution agreement Smith purports to convey his interest in the disputed property, Smith had nothing to convey as Osguthorpe was at all times the owner of the property. Thus, they argue Smith’s promise to sell subject to a reservation when he had no interest to sell does not “suffice for consideration.”
¶ 21 The dissolution agreement provides:
Except as hereinafter reserved to [Smith], [Smith] agrees to sell to [Osgu-thorpe] all of [Smith’s] right, title, interest and estate in and to all partnership assets, and [Osguthorpe] agrees to purchase from [Smith] all of his said right, title, interest and estate in and to all partnership assets upon the following terms and conditions, to-wit:
1. The partnership assets and properties covered hereby shall include:
(g) In addition to the above described property, [Smith] agrees to sell to [Osgu-thorpe], his interest in the following described real property located in Summit County, Utah, subject, however, to the reservation of interests therein by [Smith] as hereinafter specifically set forth:
[property description in metes and bounds].
(Emphasis added.)
¶22 The district court concluded the disputed property was a partnership asset based upon this declaration. We agree. Subparagraph (l)(g) falls under the paragraph providing that Osguthorpe “agrees to purchase ... all partnership assets
upon the following terms and conditions,”
and paragraph (1) providing that
“[t]he partnership
assets and
properties covered hereby shall include,”
and then listing the partnership properties. (Emphasis added.) In subpara-graph (l)(g), Smith agrees to sell
“his interest in the following described real property.”
(Emphasis added.) Smith and Osguthorpe were agreeing that certain properties were
¶23 The Osguthorpes argue the declaration alone is insufficient as a matter of law to establish that Smith had an interest in the disputed property because Smith was required to prove a conveyance, separate from the dissolution agreement, by Osguthorpe to Smith or their partnership that complied with the statute of frauds.
¶ 24 To satisfy the statute of frauds, “[a]ll that is required is that the interest be granted
or declared
by a writing subscribed by the party to be charged.”
Guinand v. Walton,
II. Is the Reservation of a Share of the Lease Payments an Unreasonable Restraint on Alienation?
¶ 25 The Osguthorpes argue Smith’s reservation of an interest in the sale and lease payments is void as an unreasonable restraint on alienation. Smith responds the reservation of a share of the lease payments is not a restraint on alienation but is merely an agreed upon method of splitting up the profits when the disputed property is leased. The reservation provides in relevant part:
In' the event, however, that [Osguthorpe] or his successor or successors in interest, during the lifetime of the survivor of [Smith] and [Osguthorpe], plus twenty-one (21) years, in a good faith transaction, shall sell the property, or any part thereof at a price exceeding Twenty Dollars ($20.00) per acre, plus the depreciated' cost of any fencing that [Osguthorpe] may have caused to be done on the property, then [Smith] shall share equally with [Osguthorpe] in the sales price paid over Twenty Dollars ■ ($20.00) per acre, plus said depreciated fencing cost, and if, during said period of time he, or his successor or successors in interest in the property shall lease all or any part of the property, for any period oftime commencing during said retained interest period, at a price in excess of $1.60 per acre per year, [Smith] shall share equally in the excess rental over the $1.60 per acre per year.
¶26 In
Redd v. Western Savings & Loan Co.,
“is an attempt by an otherwise effective conveyance or contract to cause a later conveyance (a) to be void; or (b) to impose contractual liability on the one who makes the later conveyance when such liability results from a breach of an agreement not to convey; or (c) to terminate or subject to termination all or a part of the property interest conveyed.”
Id.
at 762 n. 1 (quoting Restatement of Property § 404). Traditionally, direct restraints have been held to be void.
See Page v. Page,
¶ 27 “An indirect restraint on alienation arises when an attempt is made to accomplish some purpose other than the restraint of alienability, but with the incidental result that the instrument, if valid, would restrain practical alienability.”
Redd,
¶ 28 The pivotal issue in the present case is whether the provision that Osguthorpe
share the lease payments
with Smith restrains practical alienability and thus is an indirect restraint on alienation.
6
Utah appellate courts have not considered this issue. However,
Holiday Out in America at St. Lucie, Inc. v. Bowes,
¶ 29 Even if we were to hold the rent sharing provision in the present case is an indirect restraint, we would conclude it can
¶ 30
Kerley v. Nu-West, Inc.,
“1. the one imposing the restraint has some interest in the land which he is seeking to protect by the enforcement of the restraint; 2. the restraint is limited in duration; 3. the enforcement of the restraint accomplishes a worthwhile purpose;
4. the type of conveyances prohibited are ones not likely to be employed to any substantial degree by the one restrained;
5. the number of persons to whom alienation is prohibited is small; 6. the one upon whom the restraint is imposed is a charity.”
Id. at 634 (quoting Restatement of Property § 406 cmt. i (1944)).
¶ 31 In upholding the restraint, the Arizona Court of Appeals noted the sellers retained an interest in the adjoining land. See id. at 635. The court then emphasized the “whole purpose of the agreement was to develop and sell land — the very antithesis of the purpose of those practices that gave rise to statutes and decisions [traditionally] forbidding quarter sales and unreasonable restraints on alienation.” Id. The court further emphasized the developer knew when he bargained for the agreement that he had to project his profit or loss plus the ten percent reservation on the price of the property. See id. The court also emphasized that although “[a]s written, the obligation to pay money [was] unlimited as to time ... [t]he law ... implie[d] that it [would] be carried out within a reasonable time.” Id. Thus, although the power to trigger the obligation to pay the ten percent was within the developer’s control, if the sellers took no legal action to see that the spirit of the agreement was enforced, “laches [might] foreclose [their] right to receive the ten percent payment” upon resale. Id. at 636.
¶ 32 In the present case, Enoch Richard Smith alleges his father’s justification for the reservation was to allow him to participate in the disputed property’s future increase in value. Further, the record shows the reservation did not prevent alienation twice — to the family partnership and to the Canyons. In fact, the Osguthorpes leased the property for twenty-eight years and it has been improved. Thus, we conclude the reservation of a share of the lease payments is enforceable.
III. Does the Dissolution Agreement Entitle Smith to Share in the Lease Payments Although the Osguthorpes Use Portions of the Disputed Property for Grazing?
¶ 33 The Osguthorpes assert the dissolution agreement provides that they do not have to share the lease payments with Smith so long as they use the disputed property for grazing in connection with their sheep and cattle operations.
¶ 34 The dissolution agreement provides:
So long as [Osguthorpe] shall use said real property as grazing lands in connection with his operation of a sheep or cattle business, [Osguthorpe] shall have the right to the possession and use of the property without compensation to [Smith], but he shall pay the taxes and any expense of maintaining the property. In the event, however, that [Osguthorpe] or his successor or successors in interest ... shall lease all or any part of the property, for any period of time commencing during said retained interest period, at a price in excess of $1.60 per acre per year, [Smith] shall share equally in the excess rental over the $1.60 per acre per year.
(Emphasis added.)
¶ 35 The Osguthorpes allege that Smith’s counsel assured Osguthorpe that the dissolution agreement would only require him to share lease payments if he ceased using the property for grazing. We agree with the district court that the Osguthorpes’ allegation is contrary to the unambiguous plain language of the agreement and that Smith is entitled to share in the lease payments even though the Osguthorpes continue to use part of the disputed property for grazing.
IV. Does the Dissolution Agreement Entitle Smith to Share in the Lease Payments?
¶ 36 The Osguthorpes argue that because the lease does not grant the Canyons an exclusive right of possession, Smith is not entitled to share in the lease payments under the dissolution agreement. They maintain the lease grants a nonexclusive easement because they retain the right to possess, improve, and control the property.
¶37 The dissolution agreement provides that Smith is entitled to share in lease payments if the Osguthorpes lease “any part” of the disputed property. The district court ruled the lease was for a leasehold interest. The court emphasized that the lease is titled “Lease Agreement” and identifies the Osgu-thorpes as the lessors and the Canyons as the lessee. The court further emphasized that the lease requires the Canyons to pay “rent.” Thus, the court ruled the dissolution agreement requires the Osguthorpes to share the lease payments. The Osguthorpes argue the district court elevated form over substance in focusing on the nomenclature “lease.”
¶ 38 “A lease conveys an interest in land and transfers possession.”
Keller v. Southwood N. Med. Pavilion, Inc.,
V. Do Issues of Material Fact in Regard to Allocation of the Lease Payments Preclude Summary Judgment on Damages?
¶ 39 The Osguthorpes maintain the district court erred in ruling that the entire payment due under the lease and the amendments is for use of the disputed property because the
¶40 The district court ruled the lease and the amendments are integrated. However, it is unclear from the district court’s ruling whether the court considered the parol evidence offered by the Osgu-thorpes in so ruling. The court also ruled that any “side oral agreement” for services by Stephen violated the statute of frauds.
¶ 41 In first determining whether the lease and the amendments are integrated, the district court was required to consider “parol evidence, indeed any
relevant
evidence,”
Union Bank v. Swenson,
¶ 42 The initial lease makes no reference to services, nor does it include any language that even ambiguously alludes to services. The first amendment provides that Stephen is to approve construction of certain roads and trails and the Canyons “will include the Osguthorpes in their master planning process.” It also provides the lease parties are to “work together in good faith” and “maintain open communications.”
¶43 The Osguthorpes offered affidavits and deposition testimony that Osguthorpe and Stephen met with the Canyons after it succeeded to Wolf Mountain’s interest in the lease. The Osguthorpes and the Canyons allegedly orally agreed that Stephen would assist the Canyons with obtaining permits and with the development of the disputed property. The Osguthorpes also offered two checks from the Canyons for the annual lease payment. The 1999 check listed Stephen as the payee.
¶ 44 In his deposition, Blaise Carrig (Car-rig), the Canyons’ director, testified that because of time constraints and the parties’ relationship, the first amendment was brief and does not include a detailed description of the personal services. Carrig further testified that use of the property was worthless without the Osguthorpes’ support in obtaining permits and “consultation to make the whole operation and planning ... work.” Carrig also testified that the lease amendment language that the Canyons and the Osguthorpes agree to “work together in good faith” and “maintain open communications” establishes that part of the lease payment is for services.
¶ 45 We cannot determine from the record whether the district court considered the offered parol evidence to determine as a threshold matter whether the lease and the amendments are an integrated agreement.
See Colonial Leasing Co. of New England, Inc. v. Larsen Bros. Constr. Co.,
¶ 46 On remand the district court should make clear it considered the parol evidence in ruling the lease and the amendments are integrated or it should take evidence to determine if the lease and the amendments are integrated. The district court should determine based on the lease and the amendment terms, testimony of the parties to the lease and the amendments, and the circumstances surrounding their execution if they are integrated. Even if the evidence offered on remand “is uncontroverted, [the district] court is free to disregard such [evidence] if it finds the evidence ‘self-serving and not credible.’ ”
Glauser Storage, L.L.C., v. Smedley,
VI. Did the District Court Err by not Ordering Joinder of Stephen and the Canyons?
¶ 47 In essence, the Osguthorpes argue the district court erred by inviting, rather than ordering, joinder of Stephen and the Canyons because they are indispensable parties. Under Rule 19 of the Utah Rules of Civil Procedure, a party must be joined if that party is necessary and it is feasible to join that party.
See
Utah R. Civ. P. 19. “The underlying purpose of rule 19 requiring joinder of necessary parties is ‘ “to protect the interests of absent persons as well as those already before the court from multiple litigation or inconsistent judicial determinations.” ’ ”
Grand County v. Rogers,
¶ 48 “Under rule 19, the [district] court must first determine whether a party is necessary.” Id. at ¶ 29. A party is necessary if:
“(1) in his absence complete relief cannot be accorded among those already parties, or (2) he claims an interest relating to the subject of the action and is so situated that the disposition of the action in his absence may (I) as a practical matter impair or impede his ability to protect that interest or (ii) leave any of the persons already parties subject to a substantial risk of incurring double, multiple, or otherwise inconsistent obligations by reason of his claimed interest.”
Id. at ¶ 28 (quoting Utah R. Civ. P. 19(a)). If the court concludes a party is necessary, “the court must next consider whether joinder of the necessary party is feasible.” Id. at ¶ 29. If joinder is feasible, the necessary party “ ‘shall be joined.’ ” Id. (quoting Utah R. Civ. P. 19(a)).
¶ 49. The district court concluded that although Stephen and the Canyons did not have an interest in Smith’s action generally, they did have an interest in the court’s ruling that the lease payments were for use of the disputed property not for personal
¶ 50 In their opening brief, the Osgu-thorpes fail to discuss specific facts showing how Stephen or the Canyons, “based on the criteria set forth in rule 19(a), [are] necessary parties] to this action.”
Green v. Louder,
¶ 51 “Without more, delay is not a proper reason to deny joinder under [r]ule 19.”
Le-Pet, Inc. v. Mower,
¶ 52 Further, rule 19 allows joinder where there is a “substantial risk” of inconsistent obligations. Utah R. Civ. P. 19(a). Here, according to Stephen’s affidavit, Osguthorpe allocates the lease payments. Arguably, Stephen’s interest and the Canyons’ interest in the district court’s ruling in regard to the lease payments are identical — they both share a concern that services are a significant part of the lease payments. Although the Canyons is not bound by the district court’s decision, it seems likely that an action by the Canyons against Stephen for services would be unsuccessful.
Cf Boczon v. Northwestern Elevator Co.,
CONCLUSION
¶ 53 We conclude the dissolution agreement is integrated and enforceable. We further conclude Smith is entitled to share in the lease payments even though the Osgu-thorpes still use the disputed property for grazing and the Canyons’ possession of the same may not be exclusive. However, the district court was required to consider extrinsic evidence in determining as a threshold matter whether the lease and the amendments are integrated. We therefore reverse in part and remand for consideration of this evidence and for proceedings consistent with this opinion.

Notes
. Enoch Richard Smith filed this action as the representative of the estate of his father, Enoch Smith Jr., who died on November 11, 1996. For convenience we refer to the two as Smith.
. The Osguthorpes additionally argue the district court exceeded its discretion in failing to grant their second motion to amend. However, they fail to explain why the district court exceeded its discretion. They instead appear to ask this court to order the district court to allow amendment on remand. As Smith correctly notes, the Osgu-thorpes have the option to seek amendment on remand.
See Call v. West Jordan City,
. It is unclear whether the district court considered the parol evidence offered by the Osgu-thorpes in determining that the dissolution agreement is integrated. However, even if we were to conclude that the parol evidence was admissible to determine if the dissolution agreement is integrated and the court erred in not considering it, we conclude any error was harmless. The parol evidence does not establish that the dissolution agreement is not integrated.
In his affidavits, Osguthorpe attested that in 1966, he and Smith orally agreed to dissolve the partnership. Thereafter, he tendered $50,000 to Smith who accepted the payment. A few weeks later, Smith’s attorney contacted Osguthorpe to sign the dissolution agreement, which Osgu-thorpe reviewed. Osguthorpe also attested that the $50,000 lie paid Smith was equal to or greater than the then current market value of Smith’s partnership interest and Osguthorpe received no consideration for signing the dissolution agreement. This testimony is not persuasive on the issue of integration.
. The Osguthorpes argue the district court erred in refusing to consider parol evidence offered to support their contention that Smith's promise to sell the disputed property was illusory. Smith responds that because the dissolution agreement unambiguously declares that the disputed property was partnership property and Smith had an interest in such property, parol evidence is inadmissible. The Utah Supreme Court has recognized that parol evidence is admissible to show lack or want of consideration,
see Union Bank v. Swenson,
. The Osguthorpes also argue Smith's promise to sell some undefined “interest” in the property fails for lack of specificity under the statute of frauds. "[A] real property interest may be transferred through [a deed or] other documents and memoranda revealing an intent to transfer an interest in real property.”

Moreover, although quarter sales traditionally have been considered void as unreasonable restraints on alienation,
see, e.g., United States v. 397.51 Acres of Land,
. The Osguthorpes also argue the lease grants only a license to the Canyons. A license "is the permission or authority to engage in a particular act or series of acts upon the land of another without possessing an interest therein.”
