Maine requires the petitioner to list the grounds for divorce in the divorce petition. Fault grounds include adultery, impotence, extreme cruelty, desertion, drug and alcohol abuse, failure of one spouse to support the other adequately, confinement in a mental institution for at least seven years prior to action, and abuse. Spouses can also file on no-fault grounds based on irreconcilable differences but the court can order counseling if the non-filing spouse argues against this claim.
