As long as you and your ex can agree on how to divide up your assets, there is no need to involve lawyers or the court system. Even if children are involved, in most states you have the opportunity to separate in private, ing to whatever arrangements the two of you agree on.
There is no minimum amount of time a couple needs to live together to be considered common law married. For example, a couple could live together for one day and be considered common law married if they agree to be married and hold themselves out as such.
In Texas, specific rules govern the concept of common law marriage, including the “common law marriage 6 months rule.” This rule stipulates that couples can be considered legally married if they have lived together and presented themselves as a married couple for at least six months, along with meeting other criteria.
Unlike some states, Texas does not recognize common law marriage. This means that simply living together for a certain amount of time does not automatically entitle unmarried partners to the same legal rights and responsibilities as married couples.
As the law presently stands, when one party dies, the surviving partner in a non-married relationship is rendered similarly legally compromised if the deceased failed to make specific arrangements or provision in a will for that person.
Texas is known as one of the more difficult states to receive maintenance but does have a "10-year rule." This rule only allows a spouse to seek spousal maintenance if the marriage lasted 10 years or longer but does not automatically guarantee that a spouse in a marriage of this duration will receive maintenance.
