Oskar Ocampo took the stand in a contract dispute. Before answering questions, he recited an affirmation promising to tell the truth in a form that impressed the duty on his conscience. The court then permitted his testimony on matters within his personal knowledge.
Express Warranty by Affirmation
Otis Olsen, a boat dealer, told buyer Onyx O'Reilly that a used vessel had never been in an accident. The statement became part of the basis of the bargain. When Onyx later discovered collision damage, the affirmation created an express warranty that the boat failed to meet.
Registered Agent Designation
Odette Orozco formed Orbit Communications LLC and designated a registered agent in the formation documents. The designation operated as an affirmation that the agent had consented to serve. The company thereby satisfied the statutory requirement to maintain an agent in the state.
Divorce Petition Under Oath
Osprey Aviation's owners, a married couple, filed a joint petition stating under oath that their marriage was irretrievably broken. Neither party denied the allegation. After a hearing the court made the required finding and dissolved the marriage.
Common questions
Frequently Asked
5
What form must an oath or affirmation take to satisfy the witness-competency rule?+
The declaration must be in a form designed to impress the duty to testify truthfully on the witness's conscience. No particular religious wording is required. An affirmation that binds the conscience without invoking a deity is sufficient.
Supporting sources
Does an unsigned pleading satisfy Rule 11(a)?+
No. Every pleading must be signed by at least one attorney of record or by an unrepresented party. An unsigned paper must be struck unless the omission is promptly corrected after notice.
Supporting sources
When does a seller's statement create an express warranty under the UCC?+
Any affirmation of fact or promise that relates to the goods and becomes part of the basis of the bargain creates an express warranty. Formal words such as "warrant" are unnecessary. A mere opinion or commendation does not create a warranty.
Supporting sources
What finding must a court make when both spouses state under oath that their marriage is irretrievably broken?+
The court shall make a finding whether the marriage is irretrievably broken after a hearing. If one party denies the allegation under oath, the court must consider additional statutory factors including prospects for reconciliation.
Supporting sources
Why must a search warrant be supported by oath or affirmation?+
The Fourth Amendment requires that warrants issue only upon probable cause supported by oath or affirmation. The sworn statement supplies the factual basis the magistrate uses to determine whether probable cause exists and to describe the place and items with particularity.
