Usage notes
In non-legal usage, almost exclusively used in the passive, in form âobligated to Xâ where âXâ is a verb infinitive or noun phrase, as in âobligated to payâ. Further, it is now only in standard use 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).
