The primary requirements concern issues such as the distribution of assets acquired jointly or individually during the marital stay, custody of children, the division of child custody debts, the setting of a child support ceiling, etc. In California, a couple may waive their property-sharing (co-ownership) rights through a prior contract.  The agreement may limit sp assistance (although a court may set it aside in the event of a divorce if it considers the restriction to be unacceptable). The agreement can be used as a contract to make a will that requires one spouse to take care of the other in the event of death. It may also restrict inheritance law in the event of death, such as the right to inheritance allowance, the right to execution, the right to take as a predetermined heir, etc.  In California, registered national partners may also enter into a prenup. Post-marriage agreements are treated very differently in California law. Spouses have a fiduciary duty to each other, so pre-marital agreements fall into a particular category of agreements. There is a presumption that the post-parental agreement was obtained by undue influence when a party gains an advantage. Disclosure cannot be abandoned as part of a post-marriage agreement. [Citation required] In accordance with the provisions of Article 10 of the Ukrainian Family Code, conjugal relations, rights and obligations of spouses may also be governed by a marriage contract, if the spouses wish to settle their property by other means, they are then provided for by the Family Code of Ukraine. A conjugal agreement with the mutual and free consent of the parties may guide the courts during the divorce proceedings.
If the parties marry with the application of the delimitation, their respective discounts would remain separated during the stay of the marriage. In the event of a dissolution of the marriage, whether it is a death or a divorce, the spouse with the slightest limit would be entitled to a right against the spouse with a greater limit for half the difference between their limit values. The agreement should also have a deterrence clause, which means that if one of the clauses of the agreement is invalidated, the rest of the agreement is still valid. In the past, couples have entered into pre-marriage agreements with some uncertainty as to their validity. Today, the presumed validity and applicability of such agreements is no longer at issue in states that have adopted UPAA/UPMAA, including Florida, Virginia, New Jersey and California.  It is the sanctity of the bond created by marriage that still makes divorce a taboo in most communities around the world.
