delivered the opinion of the court.
The appellant’ in this ease, sued upon a promissory note payable December 30, 1906, demurred to the same on the ground that the action had prescribed. • The district court, trying the case de novo on appeal, sustained the demurrer, but permitted the complainant to amend at the trial. This he did in the following terms: ‘ ‘ That the promissory note described in the first paragraph of the complaint has been extended and renewed by the complainants on various occasions during the years 1907,1909 and 1911, with the consent and on petition of the defendant.”
Upon such amendment being allowed the defendant demurred on the grounds that the complaint was ambiguous, unintelligible and uncertain, and that such complaint did not state a cause of action inasmuch as it did not set forth that the interruption of the prescription took place in writing in accordance with section 48 of the Code of Civil Procedure. The district court overruled the demurrer and the appellant alleges error.
With respect to the alleged ambiguity, the appellant maintains that no one could tell in what day, month or year the alleged renewals took place. Perhaps the court should have required the complainant to be a little more specific, but if this was any error it was harmless, as the defendant was clearly apprised that at various times before the period of prescription had been completed the defendant had renewed or extended his note, and if it were important for him to know the exact dates he could have applied for a bill of particulars.
With respect to the fact that the complaint failed to say that the new promise was in writing, it is difficult to tell to. *138what causes of action or kinds of prescription section 48 of the Code, of Civil Procedure refers. The section is as follows:
“Section 48. — No acknowledgment or promise is sufficient evidence of a new or continuing contract, by which to take the case out of the operation of this title, unless the same is contained in some writing, signed by the party to be charged thereby.”
The title relates principally to disabilities, and no distinct actions or periods of prescription are described. However, supposing that section 48 refers to all periods of prescription there is nothing in the code which requires that a complaint alleging a new promise must set forth that sucji new promise was in writing.
In the various States of the Union the evidence of certain contracts is required to be in writing, but it is not necessary to allege in a pleading that the defendant contracted in writing. Furthermore, a contract may be renewed by partial payments and promise is not the o^y indispensable thing to interrupt a period of prescription.
The case went on to trial and the opportune moment for the defendant to avail himself of the provisions of section 48,, if applicable to his case, existed when evidence of verbal promises was given by the complainants. The defendant made no objection at the trial, and any objection to the failure to prove a new promise in writing was waived. Falero v. Falero et al., 15 P. R. R., 111; 38 Cyc., 1393, 1395, Trial; 20 Cyc., 320, Statute of Frauds.
The defendant answered alleging payment. The district court considered the evidence and found that only about sixty dollars had been paid, and. gave judgment for the balance, and no error is alleged.
In this court attorney for the appellant verbally alleged that the district court should not have allowed an unsworn amendment. As this was not a jurisdictional defect and was not raised below it must be held to be waived, especially as *139it is not made an assignment of error as required by rules 42 and 43 of this court.
The judgment must he affirmed.'
