Differences between spouses that are considered sufficiently severe to make married life together more or less impossible. In a number of states, irreconcilable differences is the accepted ground for a no-fault divorce. As a practical matter, courts seldom, if ever, inquire into what the differences actually are, and routinely grant a divorce as long as the party seeking the divorce says the couple has irreconcilable differences. Compare incompatibility; irremediable breakdown.

A mistake by both spouses in a marriage that can serve as grounds for an annulment. For example, if one spouse went into the marriage wanting children while the other did not, they have a misunderstanding that will be judged serious enough for a court to terminate the marriage.

In some states, a type of marriage in which couples can become legally married by living together for a long period of time, representing themselves as a married couple and intending to be married.

Federal taxes assessed on any gift, or combination of gifts, from one person to another that exceeds $12,000 in one year. Several kinds of gifts are exempt form this tax: gifts to tax-exempt charities, gifts to your spouse (limited to $120,000 annually if the recipient isn't a U.S. citizen) and gifts made for tuition or medical bills. In addition to the annual gift tax exclusion, there is a $1 million cumulative tax exemption for gifts. In other words, you can give away a total of $1 million during your lifetime -- over and above the gifts you give using the annual exclusion -- without paying gift taxes.
