If she is a resident of NY for two years or more, she can sue for divorce without his consent-based upon the no-fault provision of the NY domestic relations law.
She will have to serve him w/ a summons and complaint.
If she is located in the NYC metro area, she should contact me to arrange for a meeting to
Discuss the matter in greater length.
