H. L. LEACH, Sr., Irene G. Leach, H. L. Leach, Jr., and P. C. Williams, as Individuals, and doing business as Associated Industries, Plaintiffs in Error,
v.
Clarence V. LaGUARDIA and Rose LaGuardia, Defendants in Error.
No. 21481.
Supreme Court of Colorado, In Department.
July 3, 1967.
Coit & Walberg, Leonard R. Liss, Denver, for plaintiffs in error.
Joseph N. Lilly, Denver, for defendants in error.
SUTTON, Justice.
This writ of error arises out of a dispute between a landlord and a tenant over who is entitled to $15,000 in remaining proceeds out of $80,000 received in a condemnation action when the City and County of Denver acquired certain lands for a new public library.
The record discloses that Clarence and Rose LaGuardia were the lessors and that the lessees were H. L. Leach, Sr., H. L. Leach, Jr., Irene Leach and P. C. Williams, d/b/a Associated Distributors. Both sides claimed the escrowed balance of the money paid by the city.
The resolution of the entire dispute hinges on the legal interpretation to be be given a three page written lease entered into by the parties. This lease was signed on December 7, 1962, and was to run for five years beginning on January 1, 1963. The lease itself consisted of three pages. The first was on a realtor's printed form and attached to that was a typewritten page, neither of which had any termination *624 provisions. However, a third sheet of paper, executed at the same time and signed by the contracting parties, related to the termination provisions.
We agree with the trial court that all three pages constitute one instrument. We therefore must determine the meaning of the termination provisions which read:
    "Notwithstanding anything
  herein contained to the contrary,
  it is understood and
  agreed that in the event the
  landlord enters into a lease
  of 25 years or longer, covering
  the entire building in
  which the demised premises
  are located or in the event
  the landlord decides to raze
  the building in which the
  demised premises are located,
  this lease may be terminated
  on _____________, or any
  time thereafter, between landlord,
  his heirs, or assigns,
  upon giving not less than three
  months prior written notice,
  and said date for said termination
  under said notice shall
  be the date of the end of the
  terms of the lease as though
  provided originally for the
  expiration of the term of
  said lease.
    "And the Lessor or Lessee
  is hereby granted the right to
  terminate this lease upon three
  (3) months notice in writing
  to the Lessor at anytime after
  the first day of January, 1963.
    "Clarence V. Laguardia 12/7/62
    Rose LaGuardia
    H L Leach"
In view of the obvious conflict between the two above quoted termination provisions, and the confusion created by the proviso as to whom the notice of termination should be given, the trial court took evidence relating to how page three happened to be executed and what the parties intended thereby. It then found that the lessor had the right to terminate the lease at willsuch being the true intent of the parties at the time of the signing. Parenthetically it might be stated that the evidence demonstrated that both parties knew prior to the signing that the city was contemplating a taking of the property for public purposes; thus, it was indeed logical for the trial court to conclude that the owner wanted to and did retain the right to terminate.
It is an old and widely recognized rule that written documents containing ambiguities or unclear language or meaning are to be construed with reference to the intent of the parties. Denver Plastics, Inc. v. Snyder, Colo., 416 P.2d 370 (1966); Buckhorn Plaster Co. v. Consolidated Plaster Co., 47 Colo. 516, 108 P. 27 (1910). Since the parties intended to provide for termination by the lessor in the manner in which such was done here, and since the record shows (and there is no dispute in this regard) that notice to terminate was properly given, the lease was terminated as of November 7, 1963. Thus, at the subsequent date when the condemnation took place, Leach and his associates held no right or interest in the property in question and were not entitled to any portion of the proceeds.
The judgment is affirmed.
MOORE, C. J., and DAY and HODGES, JJ., concur.
