Most states are “not a mistake” when it comes to divorce, but in the state of Texas, courts can award a disproportionate amount of the estate in some cases of infidelity, based on “the expense of the collective good to someone other than your spouse or children – the waste of collective property,” Austin says. We have previously blogged about the benefits of a marriage agreement (commonly called pre-nup, and also known as marriage agreement). We are now turning to some kind of clause that can be included in a marital agreement: the lifestyle clause. But sometimes an infidelity clause can be effective simply because a cheating husband may not want “evidence” of his affair made public in court. As Illinois lawyer demarcial Debra DiMaggio points out, it can be difficult to prove infidelity. There may be good reasons to include an infidelity clause in your agreement. What for? Because an infidelity clause in a marriage pact gives you the ability to set your own rules as a couple and perhaps even survive your state`s divorce laws. Studies have found that men are more likely to have extramarital sex when they are sexually dissatisfied, while women are more likely to have extramarital sex when they are emotionally dissatisfied.  Kimmel and Van Der Veen found that sexual satisfaction may be more important for husbands and that women are more concerned about compatibility with their partners.  Studies suggest that people who can separate notions of sex and love are more likely to accept situations of infidelity.  A study conducted by Roscoe, Cavanaugh and Kennedy showed that female dissatisfaction was the leading cause of infidelity, while men reported a lack of communication, understanding and sexual incompatibility.  Glass and Wright also found that men and women involved in sexual and emotional infidelity were the most dissatisfied in their relationships than those who commit sexual or emotional infidelities on pure ones alone.  In general, discontent in marriage is the main cause of infidelity of both sexes.
 It is important to note that there are many other factors that increase the likelihood that someone will be unfaithful.  People who have sexually generous attitudes and those who have had a large number of previous sexual encounters are also more likely to be infidelity.  Other factors such as being well trained, living in an urban centre, being less religious, having a liberal ideology and values, having more opportunities to meet potential partners, and being older have influenced the likelihood of being involved in an extramarital affair.  The spread of sex chat rooms and dating apps has increased the ability of people in a committed relationship to participate in infidelity actions on and off the Internet.
