Legal Question in Family Law in Texas

I think you are talking about a document to ensure that there is no argument that the parties are "informally married" married by meeting three elements...one of which is co-habitation.

I draft this document for clients for a flat fee of $200. As with all legal matters, be careful in just finding a random internet form and doing it yourself.
