Goldie H. KIZER
v.
Jack S. BURK
No. 66874.
Supreme Court of Louisiana.
September 3, 1980.
*1052 Roger M. Fritchie, Durrett, Hardin, Hunter, Dameron & Fritchie, for defendant-applicant.
Robert L. Kleinpeter, Kleinpeter, Kleinpeter & Kleinpeter, for plaintiff-respondent.
DIXON, Chief Justice.
Goldie Kizer brought this declaratory judgment action to terminate defendant's rights under a "Surface Lease and Agreement to Buy and Sell," to relieve plaintiff from any further obligation under the contract, and for supplemental relief. There was judgment for the plaintiff in the trial court, and the Court of Appeal affirmed. Writs were granted on defendant's application.
Plaintiff's husband, Roland Kizer, and Jack Burk were friends of long standing, both mature businessmen. In the course of frequent social encounters it was agreed that a farm in East Feliciana Parish, owned by Goldie Kizer, would be leased to Burk for three years and sold to him at the end of the lease. On August 27, 1976 a contract for the lease and purchase of the 276 acre farm, prepared by Roland Kizer, was executed by Roland and Goldie Kizer and Jack S. Burk. A copy of the lease is attached in an appendix.
Among other obligations of the contract, it provided: "The LESSEE further agrees that the cultivation of the crops and the maintenance of the pasture will be done in a good and workmanlike manner and LESSEE will carefully and faithfully guard and protect the said premises." At the time of the sale, vendors were to reserve one-half of the minerals.
This suit was filed on February 7, 1978. The abrogation of the agreement was sought for two reasons: Jack Burk had executed a timber deed on the Kizer farm on December 27, 1976, for which he had been paid $11,300, and had executed an oil and gas lease on the property on October 21, 1977.
On the representations of defendant that the timber sale and oil and gas lease were not inconsistent with the objectives of the lease, were consistent with the basic objectives of the particular contract, and were executed with the knowledge, acquiescence or subsequent approval of the parties, we granted the application for review.
The record does not support defendant's contentions. Although defendant's actions were consistent with his own plans for the development and financing of the farm, he presumed too much, and did not have the owner's consent when he dealt with property which was not his own, nor did the owner ratify defendant's actions in any way.
Kizer did not know of the timber sale until some neighbors told him of its removal in April of 1977. Kizer wrote to Burk for an explanation. Burk explained that he felt that he had the right to dispose of the timber, since he planned to clear the land so it could be in full production at the time of the purchase, when there would be substantial payments due on the purchase price and interest. Recognizing his lack of ownership of the timber, Burk suggested that he either turn the money over to Mrs. Kizer and receive a diminution in the purchase price when the sale would be completed, or keep the funds and pay interest on them until that time. There were further discussions, but no clearly determinable agreement. Kizer testified that he thought it was decided that Mrs. Kizer should take the funds; Burk thought that no determination had been communicated to him. The funds were not returned, and the "land clearing" was never completed.
As with the problem of the timber proceeds, so went the problem of the mineral lease. There was correspondence, conversation, talk of different offers, but no agreement. Burk eventually executed the mineral lease without the Kizers, even though he would own no mineral interests until the sale was made.
Under the provisions of the Civil Code, a tenant is required to utilize the *1053 leased property as a good administrator, according to the use for which it was intended by the lease. C.C. 2710(1). The landowner may obtain dissolution of the lease if the lessee makes another use of the premises than that for which it was intended, or if the lessee fails to fulfill his obligations under the lease. C.C. 2711, 2729. The lease may itself provide the purpose for which the premises are to be used and for restrictions on the use of the premises, but in the absence of such provisions, the court may look to the surrounding circumstances, such as the nature of the situation, and previous use of the property. Tullier v. Tanson Enterprises, Inc., 367 So.2d 773 (La. 1979); Comment, The Louisiana Law of Lease, 39 Tul.L.Rev. 798, 856-859 (1965).
Initially it should be noted that the sale of the timber was clearly beyond the authority granted under the agreement. At the time of the agreement and the timber sale, C.C. 465 provided:
"Standing crops and the fruits of trees not gathered, and trees before they are cut down, are likewise immovable, and are considered as part of the land to which they are attached."
Therefore, the standing timber on the leased property must be considered as a part of the leased estate. The agreement clearly did not give the lessee the power to alienate any part of the leased premises. To the contrary, the lessee agreed to faithfully and carefully guard and protect the premises. A lease is a synallagmatic contract whereby the owner of the thing leased grants to the lessee the enjoyment of the thing for a certain time. C.C. 2669, 2674. It does not give the lessee the power to alienate all or part of the leased thing. C.C. 2719.
We agree with the trial court and the Court of Appeal that the sale of the standing timber was an unintended use of the premises. In addition, we note that the sale without authority of the timber which the lessee did not own can hardly be reconciled with the defendant's duty, under the lease provisions, to faithfully and carefully guard and protect the leased premises, since he in fact alienated a part of the premises. Therefore, the plaintiff was entitled to a dissolution of the contract because of the defendant's actions. C.C. 2711, 2729.
Furthermore, the plaintiff did not waive her right to complain of the breach, or consent to the unintended use of the premises, by accepting the rent installment due on September 1, 1978. In Illinois Central Gulf R. Co. v. International Harvester Co., 368 So.2d 1009 (La.1979), this court noted that the Civil Code and statutes of this state do not provide for any legal presumption of consent to arise from a lessor's silence and acceptance of rent. We noted a number of cases from which it might appear that a lessor condones a violation of a lease by accepting rent, but concluded that those cases involved a determination that the lessor either impliedly consented to a modification of the lease or forgave a breach thereof. Among those cases were Arms v. Rodriguez, 232 La. 951, 95 So.2d 616 (La.1957) and Major v. Hall, 251 So.2d 444 (La.App.1971), cited by defendant in the instant case. After a careful review of the facts, however, we conclude that the lessor in the instant case did not consent to the use of the premises made by the defendant, or forgive him the breach.
The record indicates that, far from having consented to the timber sale, or forgiven it, at the time the 1977 rental payment was accepted the plaintiff, through her husband, was making efforts, consistent with his friendship with the defendant, to have the matter settled and her interest protected. We cannot say that merely because Mr. Kizer sought to have the matter settled amicably without resort to legal proceedings, that the plaintiff consented to the sale of the timber, or that she forgave the defendant for the breach of contract.
From a reading of the lease and purchase agreement provisions it is clear that the parties intended that the contract to sell at the termination of the lease be conditioned on the faithful performance of the obligations under the lease. C.C. 2026. The performance of those obligations was therefore a suspensive condition of the contract to sell. Since the condition failed to occur and the defendant breached the *1054 agreement, the plaintiff is under no obligation to sell the property to the defendant.[1]
For the reasons assigned, the judgment of the Court of Appeal is affirmed. Costs are to be paid by defendant-appellant.

NOTES
[1]  Although we do not disagree with the Court of Appeal in holding that the unauthorized mineral lease by Burk, who had not yet acquired any mineral ownership, was a detrimental use of the leased premises, it is unnecessary to decide that issue.
