Neither. Women no longer are required to reveal their marital status by using special titles. The use of Ms. evolved in the twentieth century and serves the same purpose as Mr. for people who prefer to begin a name with a title.
A divorced woman is a Mrs. If her name is Sally Reid and she was married and now divorced from Peter Reid she is no longer Mrs. Peter Reid. As a divorced woman she is now Mrs. Sally Reid. Those saying a divorced woman is a Ms. are incorrect. A divorced woman, a single woman, or a married woman may choose to use Ms. Ms.basically means "guess" or "my marital status is none of your business."
Ms.
miss.
You address a woman as Mrs. when you know she is married. When you know she is single you address her as Miss. When you are uncertain about her marital status it is best to address her as Ms.
divorced woman is a Ms. Once the divorce is executed, the women in no longer a Mrs.
Mrs. is a title of respect that may be used to address a married woman. Ms. is preferable, especially if you do not know what the woman's preferred title is, or if you do not know the marital status of the woman.
"Mrs" is the term of address used for a married woman. "Miss" is used for unmarried women and girls.
You can use Mrs., Miss, or Ms., depending on the marital status and preference of the woman.
it depends if she is married Mrs. if not miss if she has been married but not anymore then Ms.
If you are divorced, you can use the prefix "Ms." if you prefer not to use "Mrs." or "Miss". It is a neutral form of address that does not indicate marital status.
Traditionally in England a woman called Mary, married to a man called John Smith, would be known as "Mrs John Smith" when married, and as "Mrs Mary Smith" when divorced. Many women nowadays prefer to be known as "Mrs Mary Smith" even when married. Divorced women may also be known as "Ms Mary Smith" ('Ms' is pronounced 'Muz'). "Ms" is also used by single women who do not like "Miss". The previous answerer, who is obviously doesn't like traditional forms, wrote "Anything but Mrs." Of course it is always courteous to address a woman by the way she has said she prefers; some divorced women revert to their maiden name.
You can address an unmarried woman as "Ms." just as well as a married woman. In a situation where you are unsure of the marital status, "Ms." is a safe form of address, and avoid "Miss" and "Mrs."
