When issues of paternity come up, it's rarely a question mark of who the mother is, as the child was brought into this world by her. Sometimes it's hard to know who the father is. Or rather, it can be difficult to prove who the father is. The legal significance of paternity allows a parent certain rights to seek visitation, custody etc. However, it also guarantees the child something.
Marriage can be a beautiful thing. It can also turn into something else, something you want to escape. Thank heavens for divorce. If married for many years, or just a short time, alimony could be a part of your divorce decree between you and your spouse.
