With respect to financial issues related to divorce, marital agreements are regularly maintained and enforced by courts in virtually all states. There are circumstances in which the courts have refused to apply certain parts/provisions of these agreements. In North Dakota.B, divorce courts retain the jurisdiction to amend a limitation on the right to apply for spousal support or assistance in a pre-marital contract if this would result in the spouse who waived that right in need of public assistance at the time of the divorce.  Florida and several other states have similar restrictions to prevent an outgoing spouse from becoming a community of the state after divorce under a marital agreement.  In addition, in Florida, the Pre-Trial Contracts Act, where inheritance (electoral quota) and thought rights granted to surviving spouses under state law are so strong that a waiver of the rights of the surviving spouse, enshrined in a matrimonial agreement, is enforceable with the same formality as the will (notarially and notably). The canonical law: the letter and the spirit, a commentary on canon law, states that the condition can be defined as "a provision by which an agreement is subject to verification or the fulfillment of a circumstance or event that is not yet certain." He added: "Any future condition related to conjugal consent invalidates the marriage." For example, a marriage would not be valid if the parties prescribed that they must have children, or they had the right to divorce and remarry. [Citation required] Even in countries that have not adopted UPAA/UPMAA such as New York, properly executed marriage contracts have the same presumption of legality as any other treaty.  It is not necessary for a couple who signs a marriage pact to keep separate lawyers to represent him as long as each party understands the agreement and signs it voluntarily with the intention of being bound by its terms. There is a strong public policy that favours parties that control and decide their own interests through contracts.
 There are no state or federal laws requiring adults with contractual capacity to hire a lawyer in order to enter into a marriage contract such as a marriage contract, with the exception of a California law that requires the parties to be represented by a lawyer if spousal assistance (support) is limited by the agreement.  The marriage agreement may be challenged if it is proven that the contract was signed under duress.  Whether a pre-marriage contract was signed under duress must be justified by the facts and circumstances of this case.
