It depends on your state. In some states - like NC- you can sue the "alienator for - you guessed it - "alienation of affection." In some, like VA, there is no community property, there is "equitable distribution" of assets. VA has no "irreconcilable differences" grounds for divorce. To get into court quickly, the divorce must be due to adultery, which VA recognizes as intolerable. The fault grounds - like adultery, domestic violence, desertion, incarceration - determine distribution of assets.
