*204Opinion
ANDERSON, P. J.Defendants James L. and Alice Pappas appeal from a judgment establishing a right-of-way by necessity across their property.
I. Facts and Procedural History
The property which is the subject of this suit consists of two adjoining parcels of land, the Highland Court parcel (Highland parcel) and the Roemer parcel. Dr. Thomas Clark recorded a deed to the Highland parcel on March 23, 1946. He acquired the Roemer parcel through an installment land sale contract entered by December 26, 1948, at the latest. (The contract could not be found, but its existence is not disputed.)
On June 30, 1950, Dr. Clark sold the Highland parcel to Evelyn and Scott Sparling; this sale left the Roemer parcel landlocked. Approximately seven months later, Dr. Clark acquired the deed (i.e., legal title) to the now landlocked Roemer parcel (on Feb. 26, 1951); on January 22, 1959, he transferred the Roemer parcel to his daughter and grandson, Georgia C. and Thomas H. Roemer, the plaintiffs herein.
The Roemers had several casual discussions with the Sparlings concerning access to public roads over the Highland parcel, and at one point they hired an attorney to assist them; his services were discontinued when Mr. Sparling assured them that they could work something out without legal assistance. However, nothing was ever done to secure an easement for the benefit of the Roemer parcel over the Highland parcel. In 1982 the Spar-lings sold a portion of the Highland parcel to the Pappases who were advised of the Roemers’ possible claim to an easement; they executed a written agreement to hold Mrs. Sparling harmless from any such claim.
Ultimately, to secure access the Roemers brought this action to quiet title in an easement by way of necessity against both the Pappases and the widowed Mrs. Sparling; they dismissed Mrs. Sparling as a party approximately two years before trial. The trial court found for the Roemers and granted them a way of necessity over the Pappases’ property.
On appeal defendants challenge the judgment on the following grounds: (1) An easement by necessity cannot have arisen, because the putative common owner (Dr. Clark) held only an equitable title to the dominant tenement when the alleged necessity arose. (2) The common owner lacked the intent to retain an easement. (3) The trial court erroneously rejected the defenses of unclean hands and “balancing of the equities.” (4) The trial court erred in locating the easement on defendants’ parcel rather than on an *205adjacent parcel. (5) Plaintiffs should be required to compensate defendants for the value of the property taken.
We reject each of these contentions and affirm the judgment.
II. A Right-of-way by Necessity Has Been Established
A. Common Ownership
The defendants first argue that the plaintiffs are not entitled to an easement by way of necessity because there never existed the requisite common ownership of the Highland and Roemer parcels for this doctrine to ■ apply. They argue that the equitable title held by Dr. Clark to the Roemer parcel was not sufficient to encumber the Highland parcel with a way of necessity when he sold it.
“ ‘A way of necessity is an easement arising from an implied grant or implied reservation; it is of common-law origin and is supported by the rule of sound public policy that lands should not be rendered unfit for occupancy or successful cultivation. Such a way is the result of the application of the presumption that whenever a party conveys property, he conveys whatever is necessary for the beneficial use of that property and retains whatever is necessary for the beneficial use of land he still possesses. . . (Daywalt v. Walker (1963) 217 Cal.App.2d 669, 672-673 [31 Cal.Rptr. 899].) The philosophy behind this presumption is that the demands of our society prevent any man-made efforts to hold land in perpetual idleness as would result if it were cut off from all access by being completely surrounded by lands privately owned. (Reese v. Borghi (1963) 216 Cal.App.2d 324, 331 [30 Cal.Rptr. 868].)
A preliminary requirement to establishing a way of necessity is that the dominant and servient tenements be under the same ownership at the time of the conveyance giving rise to the necessity. (Reese v. Borghi, supra, 216 Cal.App.2d at pp. 332-333.) Dr. Clark bought the Roemer parcel under an installment land sale contract, whereby the seller, the Moraga Company, retained legal title to the property until the final payment was made, at which point legal title was conveyed to him. Defendants admit that Clark held equitable title to the Roemer parcel when he sold the Highland parcel to the Sparlings. They contend that because Clark did not have legal title, he was not a common grantor for purposes of application of the doctrine of way of necessity. While this appears to be a case of first impression, we find the distinction without significance.
Under an installment land contract, the buyer agrees to make payments over time and the seller agrees to convey legal title to the buyer at *206some future date. “During the term of the contract the [buyer] acquires an ‘equity ownership’ in the property.” (1 Miller & Starr, Current Law of Cal. Real Estate (rev. ed. 1975) §2:32, pp. 260-261.) The seller conveys “his equitable interest in the property” (Tucker v. Lassen Sav. & Loan Assn. (1974) 12 Cal.3d 629, 637 [116 Cal.Rptr. 633, 526 P. 2d 1169]), retaining only “naked legal title” as security (Estate of Reid (1938) 26 Cal.App.2d 362, 367 [79 P.2d 451]). Equity “considers the purchaser to be the owner of the land,” and the seller is said to have “no greater rights than he would possess if he had conveyed the land and taken back a mortgage.” (Elliott v. McCombs (1941) 17 Cal.2d 23, 31 [109 P.2d 329].) The buyer’s interest is subject to property tax (Eisley v. Mohan (1948) 31 Cal.2d 637, 643), and the buyer will receive title free and clear, as against the sellers’ judgment creditors, upon making the final payment under the contract (1 Miller & Starr, supra, § 2:34, p. 268). In sum, the buyer is generally deemed the “owner” notwithstanding the retention of legal title by the seller. (See Elliott v. McCombs, supra, 17 Cal.2d at p. 31 [buyer “is for all purposes the owner”].) Here, as the trial court correctly observed, Dr. Clark as purchaser had taken possession of the property and paid taxes thereon; the seller retained legal title for security, and Clark was for all purposes the owner.
The significance of purchasing real property under an installment land sale contract as compared to buying property outright and securing the loan for that purchase with a deed of trust lies in the remedy for breach of the agreement—an action for breach of contract in the former case and foreclosure on the deed of trust in the latter. We see no reason to deny respondents the benefit of the strong public policy favoring ways of necessity simply because the common grantor (Clark) employed different means in purchasing the Highland and Roemer parcels.
B. Existence of Necessity
To establish a right to a way of necessity, strict necessity must exist; that is, when the claimed way constitutes the only access to the claimant’s property. (Lichty v. Sickels (1983) 149 Cal.App.3d 696, 699 [197 Cal.Rptr. 137]; Reese v. Borghi, supra, 216 Cal.App.2d at p. 332.) While evidence was presented that plaintiffs had contacted the owner of property abutting his on the other side of the Highland parcel and been denied access, the trial court correctly concluded that such attempt is not a prerequisite for establishing an easement by way of necessity: “Plaintiffs’ common law right to seek a right-of-way of necessity is not affected by the fact that they could have a right-of-way by condemnation [citations].” (Reese v. Borghi, supra, 216 Cal.App.2d at pp. 329-330.) Just as in Reese, “the plaintiffs here were not ‘driven to a proceeding to condemn the land on payment of its value,’ ” citing Taylor v. Warnaky (1880) 55 Cal. 350, 351. (Id., at p. 330.)
*207However, creation of a way of necessity is founded upon the salutary public policy against permitting land to remain in perpetual idleness. (Lichty v. Sickels, supra, 216 Cal.App.2d at p. 703.) And where land is not capable of being developed, ingress and egress rights will not affect that land’s idleness and no necessity for an easement then arises.
Defendants contend that the court erred in sustaining plaintiffs’ motion in limine to exclude evidence concerning the “difficulty of building on or developing the [plaintiffs’] property.” They argue that if allowed to develop this issue, they would have established the issue of the “undevelopability” of the Roemer parcel and that strict necessity did not exist because there could be no beneficial use to which the property might be put.
Defendants may be correct that if they can establish that the Roemer parcel is incapable of development and, therefore, useless, there exists no necessity for access. Since the doctrine of easement by way of necessity rests upon the public policy that the law favors utilization of land, that policy is not furthered if the land is incapable of utilization. However, defendants confuse “incapability” of development and “difficulty” of development. Plaintiffs’ motion in limine was directed to “defendant’s proposed testimony concerning the difficulty of building or developing the plaintiff’s property . . . ."1(Italics added.) Such testimony is clearly irrelevant. The court did not forbid introduction of evidence that proves the impossibility of developing the Roemer parcel. Indeed, that the property is capable of development, even though difficult, would seem to be demonstrated by plaintiffs’ investment in this lawsuit and by their willingness to pay the cost of constructing the access road. Nothing in the record before us indicates a motive on the part of plaintiffs other than development. Necessity has been established.
C. Intent Not to Retain Easement
Defendants argue that Clark did not intend to retain an easement over the Highland parcel. When the conditions for an easement by necessity are shown the law presumes that the grantor intended to reserve such an easement. (Hewitt v. Meaney (1986) 181 Cal.App.3d 361, 366 [226 Cal.Rptr. 349].) The presumption, however, is rebuttable; “an easement by necessity will not be imposed contrary to the actual intent of the parties.” (Id., at pp. 366-367.) The presumption is one affecting the burden of proof, and to overcome it the defendant must show by a preponderance of the evidence that “the common grantor did not intend to reserve an easement through the granted parcel.” (Id., at p. 367.)
*208Defendants cite the following facts in an attempt to overcome the presumption: (1) Clark made no reference to retaining access to the Roemer parcel in the deed to the Highland parcel; (2) the purchase price paid by the Sparlings was not reduced because of the reservation of an easement; (3) Clark initially offered to sell the Sparlings both parcels; and (4) that Dr. Clark, after he had already sold them the Highland parcel, telephoned the Sparlings offering to sell it to them without mentioning reservation of an easement; defendants claim this conversation constituted a disclaimer of any right of access over the defendants’ portion of the Highland parcel.
The argument is addressed to the wrong forum and ignores the respective functions of trial and appellate courts. The question of the grantor’s intent was one of fact for the trial court. (See Hewitt v. Meaney, supra, 181 Cal.App.3d at pp. 367, 368, 371.) On appeal that court’s determination cannot be disturbed if there was substantial evidence to support it. (9 Witkin, Cal. Procedure (3d ed. 1985) Appeal, § 278, p. 289.) A party who challenges the sufficiency of the evidence to support a particular finding must summarize the evidence on that point, favorable and unfavorable, and show how and why it is insufficient. (Trailer Train Co. v. State Bd. of Equalization (1986) 180 Cal.App.3d 565, 587-588 [225 Cal.Rptr. 717].)
Defendants have made no attempt to comply with these requirements. They set out only the evidence in their favor, ignoring evidence which supports a contrary view. They seem to concede that the evidence was conflicting, repeatedly asserting that their showing was “sufficient to overcome the presumption,” and that there was a “preponderance of evidence” that no easement was intended. Their citations to Hewitt v. Meaney, supra, 181 Cal.App.3d 361, are unavailing, for the trial court there found the presumption rebutted and the issue on appeal was the sufficiency of the evidence to support that finding. No such finding was made by the trial court herein, nor was one requested.
On the subject of intent the only cognizable argument raised is that the trial court erred by excluding evidence alleged to prove “the difficulty of creating access to the Roemer lot over the Highland Court parcel.” Evidence that the dominant parcel is “virtually inaccessible” over the servient parcel may, indeed, support an inference that the grantor did not intend a right of access. (See Hewitt v. Meaney, supra, 181 Cal.App.3d at p. 370.) However, the record before us does not establish that evidence of inaccessibility was ever offered or excluded. There was some discussion of soil instability, but defendants’ counsel said such evidence went to the difficulty of developing the Roemer parcel, not the difficulty of constructing or maintaining the proposed driveway. The issue of Dr. Clark’s lack of intent to *209retain an easement was never really raised at trial; we refuse to entertain it here.
