How to Write Numbers on Checks & Legal Documents

When filling out a check, contract, or legal invoice, writing the amount in words is a legal requirement to eliminate ambiguity. Financial standards demand specific formatting rules to ensure compliance and prevent tampering:

  • Explicit Currency & Sub-Units: Writing full names like “Dollars And Fifty-Six Cents” ensures exact fractional amounts cannot be misread.
  • The “Only” Suffix: Appending “Only” marks the value as final, preventing fraudulent word additions.
