Motion: A written or oral application made to a court or judge to obtain a ruling or order directing that some act be done in favor of the applicant. (TheFreeDictionary)

However, during a trial or a hearing, an oral motion may also be permitted. (definitions.uslegal.com)

An oral contract is a contract, the terms of which have been agreed by spoken communication. This is in contrast to a written contract, where the contract is a written document. There may be written, or other physical evidence, of an oral contract – for example where the parties write down what they have agreed – but the contract itself is not a written one. (Wikipedia)

Dances with Wolves actor Kevin Costner has taken legal action against a film production company he claims broke an oral agreement to pay him $8m (£4.6m). [...] The 50-year-old claimed he had "duly performed all obligations under the agreement in all material respects". (BBC News)
