Under the general rule in
Section 9 of Rule 130 of the Rules of Court, when the terms of an agreement
were reduced in writing, as in this case, it is deemed to contain all the terms
agreed upon and no evidence of such terms can be admitted other than the
contents thereof. Rudlin argues that under Section 9, Rule 130, a party
may present evidence to modify, explain or add to the terms of the written agreement
if it is put in issue in the pleading, "[t]he failure of the written
agreement to express the true intent and the agreement of the parties
thereto." Assuming as true Rudlin’s claim that Exhibit "7"
failed to accurately reflect an intent of the parties to fix the total contract
price at P6,006,965.00, Rudlin failed to avail of its right to seek the
reformation of the instrument to the end that such true intention may be
expressed.
Evidence of a
prior or contemporaneous verbal agreement is generally not admissible to vary,
contradict or defeat the operation of a valid contract. (Lapulapu Foundation, Inc. v. Court of Appeals, 466 Phil. 53, 62
(2004), citing MC Engineering, Inc. v. Court of Appeals, G.R. No. 104047, April
3, 2002, 380 SCRA 116, 137).
“SEC.
9. Evidence of written agreements. — When the
terms of an agreement have been reduced to writing, it is considered as
containing all the terms agreed upon and there can be, between the parties and
their successors-in-interest, no evidence of such terms other than the contents
of the written agreement.
However, a
party may present evidence to modify, explain or add to the terms of the
written agreement if he puts in issue in his pleading:
(a) An
intrinsic ambiguity, mistake or imperfection in the written agreement;
(b) The
failure of the written agreement to express the true intent and agreement of
the parties thereto;
(c) The
validity of the written agreement; or
(d) The
existence of other terms agreed to by the parties or their
successors-in-interest after the execution of the written agreement.
The term
"agreement" includes wills” (emphasis supplied).
Rudlin cannot
invoke the exception under (a) or (b) of the above provision. Such exception
obtains only where "the written contract is so ambiguous or obscure in
terms that the contractual intention of the parties cannot be understood from a
mere reading of the instrument. In such a case, extrinsic
evidence of the subject matter of the contract, of the relations of the parties
to each other, and of the facts and circumstances surrounding them when they
entered into the contract may be received to enable the court to make a proper
interpretation of the instrument." (Seaoil
Petroleum Corporation v. Autocorp Group, G.R. No. 164326, October 17, 2008, 569
SCRA 387, 396-397, citing OrtaƱez v. CA, 334 Phil. 514, 519-520 (1997) &
Heirs of Amparo del Rosario v. Aurora Santos, et al., 194 Phil. 670, 687
(1981).
Under the fourth
exception, however, Rudlin’s evidence is admissible to show the
existence of such other terms agreed to by the parties after the execution of
the contract. But apart from the Bar Chart and Cash Flow Chart prepared by FBC,
and the testimony of Rodolfo J. Lagera, no competent evidence was adduced by
Rudlin to prove that the amount of P6,006,965.00 stated therein as
contract price was the actual decreased amount that FBC and Rudlin found
mutually acceptable. As to the affidavits executed by Architect Quezon and
his associate Roberto R. Antonio, the same do not serve as competent proof of
the purported actual contract price as they did not testify thereon.
Significantly, the June 5, 1986 Letter-Agreement did not at all mention the
total contract price. Likewise, there is nothing in the various letters sent by
Rudlin to FBC while construction was in progress and even subsequent to the
execution of the said Letter-Agreement indicating that Rudlin corrected the
contract price of P6,933,268.00 which FBC had repeatedly mentioned in
its letters and documents (FINANCIAL BUILDING CORPORATION vs. CORPORATION,

JR., J.).
