If you want to turn your life contract into a marriage contract, you need to follow these steps: but the relationships of some couples do not end very well. They do not divide the property in silence and leave. Instead, they take their fight to court. New Jersey courts responded to these claims by trying to figure out what the couple had agreed to and dividing their property accordingly. The courts have ruled that unmarried couples generally have the right to enter into any type of cohabitation agreement they wish. However, the courts have consistently held that these agreements can only focus on financial and property matters and that they must also be fair and reasonable in the circumstances of the unmarried couple. Concubine agreements are contracts and can be repealed for the same reasons that could lead to the cancellation of a commercial contract.
