We lawyers like to use definitions in our writing. It makes the substance of the document easier to read because it allows the drafter to avoid repeating things or using terms in an inconsistent manner. I am going to try that here, knowing that I may offend someone or other.
In this article, ‘marriage’ means a romantic relationship (whether or not having a sexual component) between any two or more people of any genders or without a gender, whether or not sanctified by a religious or civil ceremony of any type, and ‘spouse’ means any of the human beings who are involved in such a relationship. I hope that I have included everyone, but I will not be surprised if I have not. Frankly, I am having trouble keeping up.
