Palimony is not based solely on the length of time you’ve lived together, but rather the state of your relationship. A court may authorize palimony if there is evidence to show that you and your partner had an arrangement that was similar to marriage. This arrangement can be verbal, written or implied. Evidence that may support the existence of a contractual relationship include:
Comingling of assets
Sharing of income and property
Co-signing major purchases
Shared credit cards
Naming your partner as a beneficiary for benefits
