#### Usage notes

In non-legal usage, almost exclusively used in the passive, in form “obligated to X” where ‘X’ is a verb infinitive or noun phrase, as in “obligated to pay”. Further, it is now in standard use only in American English and some dialects such as Scottish, having disappeared from standard British English by the 20th century, being replaced by obliged (it was previously used in the 17th through 19th centuries).
